The fadL gene of Escherichia coli codes for an outer membrane protein involved in long-chain fatty acid transport. Its product was purified from outer membrane proteins. We determined the nucleotide sequence of a 2.8-kb chromosomal DNA segment that contains the fadL gene. The fadL gene consists of a 1149-nucEeottde coding region and contains a highly hydrophobic polypeptide of 383 amino acids with a calculated molecular weight of 42 380. We have used S1-mapping analysis to identify the transcription initiation site. A region exhibiting extensive dyad symmetry and perfect homology to the catabolite activator protein binding site was detected. [ABSTRACT FROM AUTHOR]

- Abstract
Targeted recruitment of histone acetyltransferase (HAT) activities by sequence-specific transcription factors, including the retinoic acid receptors (RARs) and retinoid X receptors (RXRs), has been proposed to lead to destabilization of nucleosomal cores by acetylation of core histones. However, biochemical evidence indicates that destabilization and depletion of linker H1 histones must also occur at the promoter regions of actively transcribing genes. Mechanisms by which nuclear receptors and other transcription factors affect the removal of histone H1 from transcriptionally silent chromatin have not been previously described. In this report, we show that RARs interact in a ligand-dependent manner with HMG-I, which is known to displace histone H1 from chromatin. We further show that HMG-I and a novel related protein, HMG-R, also interact with other transcription factors. Using sense and antisense constructs of HMG-I/R in transient transfection assays with a retinoid responsive reporter, we also demonstrate that HMG-I/R is important for retinoid dependent transcriptional activity of RAR. These findings suggest a step wise mechanism by which RARs and other transcription factors can cause a targeted unfolding of compact chromatin as a first step in transcriptional activation, which would then be followed by recruitment of HAT activity and subsequent events.

- Abstract
We report the purification and localization of the fadL gene product (FLP), an essential component of the long-chain fatty acid transport machinery in Escherichia coli. FLP was extracted from total membranes by differential extraction with the nonionic detergents Tween 20 and Triton X-100. This protein was further purified from a Tween 20-insoluble-Triton X-100-soluble extract by salt fractionation, gel filtration chromatography, and hydrophobic interaction chromatography. This regime results in a 95-fold purification of FLP from total membranes. The purified protein preparation was homogeneous based on silver staining and gave the characteristic behavior established for the fadL gene product in the presence of sodium dodecyl sulfate at different temperatures prior to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (Mr of 33,000 when heated at 25 degrees C and Mr of 43,000 when heated at 100 degrees C) and on two-dimensional polyacrylamide gels (pI of 4.6 and a Mr of 33,000). Purified FLP was rich in hydrophobic residues accounting for approximately 45% of the total amino acid composition. To localize FLP, antisera were raised against the purified protein and were used to probe differentially fractionated membranes by Western immunoblotting. This procedure demonstrated the presence of this protein only in the outer membrane fraction of fadL+ strains. We confirmed the outer membrane localization of FLP by measuring long-chain fatty acid transport in fadL+ and fadL strains treated with EDTA to alter outer membrane permeability and in spheroplasts generated from fadL+ and fadL strains. Both EDTA-treated cells and spheroplasts transported long-chain fatty acids at essentially the same rate regardless of whether they contained a wild-type or mutant fadL gene. These data imply that FLP is a protein in the outer membrane which is specifically involved in long-chain fatty acid transport.

International audience; Objectives: Our aim was to assess if switching from a protease inhibitors (PI)-based regimen to a PI-free one is associated with an increased risk of Kaposi Sarcoma (KS) relapse among patients living with HIV (PLHIV) with history of KS and controlled HIV replication.Methods: In a retrospective analysis of the prospectively collected Dat'AIDS database we selected patients who both had a past KS history and a HIV-1 viral load below 200 copies/mL while being PI-treated. We searched for KS relapses while persistent virological success was maintained for at least 6 months, whether patients kept taking the PI, or switched to PI-free regimen.Results: Among the 216 patients with past KS event and a history of HIV-1 infection efficiently treated by a PI-based regimen, 148 patients (68.5%) later switched to a PI-sparing regimen. Their baseline characteristics were not different from non-switching patients. We described 7 cases of relapse (3.2% of the 216 patients). Five cases of relapse occurred in switching patients (3.4%). The remaining two relapses occurred in PI-treated patients (2.9%). At KS relapse, CD4 cell count was 459 cells/μL (range 225-560) for switching patients, compared with 362 and 136 cells/μL for the other two patients.Conclusions: In this large cohort of PLHIV with a history of KS and ART-controlled HIV replication, KS relapses were described in 3.2% of the patients, and were not more frequent when a PI-containing ART regimen has been switched to a PI-free regimen. Our results do not support a specific effect of PI on KS.

Background The arrival of highly effective, well-tolerated, direct-acting antiviral agents (DAA) led to a dramatic decrease in hepatitis C virus (HCV) prevalence. Human immunodeficiency virus (HIV)-HCV–coinfected patients are deemed a priority population for HCV elimination, while a rise in recently acquired HCV infections in men who have sex with men (MSM) has been described. We describe the variations in HIV-HCV epidemiology in the French Dat’AIDS cohort. Methods This was a retrospective analysis of a prospective cohort of persons living with HIV (PLWH) from 2012 to 2018. We determined HCV prevalence, HCV incidence, proportion of viremic patients, treatment uptake, and mortality rate in the full cohort and by HIV risk factors. Results From 2012 to 2018, 50 861 PLWH with a known HCV status were followed up. During the period, HCV prevalence decreased from 15.4% to 13.5%. HCV prevalence among new HIV cases increased from 1.9% to 3.5% in MSM but remained stable in other groups. Recently acquired HCV incidence increased from 0.36/100 person-years to 1.25/100 person-years in MSM. The proportion of viremic patients decreased from 67.0% to 8.9%. MSM became the first group of viremic patients in 2018 (37.9%). Recently acquired hepatitis represented 59.2% of viremic MSM in 2018. DAA treatment uptake increased from 11.4% to 61.5%. More treatments were initiated in MSM in 2018 (41.2%) than in intravenous drug users (35.6%). In MSM, treatment at the acute phase represented 30.0% of treatments in 2018. Conclusions A major shift in HCV epidemiology was observed in PLWH in France from 2012 to 2018, leading to a unique situation in which the major group of HCV transmission in 2018 was MSM. Clinical Trials Registration. NCT02898987.

International audience; Background - Although antiretroviral therapy (ART) has reduced the risk of Kaposi sarcoma (KS), KS cases still occur in HIV-infected people. Objective - To describe all KS cases observed between 2010 and 2015 in a country with high ART coverage. Methods - Retrospective study using longitudinal data from 44 642 patients in the French Dat'AIDS multicenter cohort. Patients' characteristics were described at KS diagnosis according to ART exposure and to HIV-plasma viral load (HIV-pVL) (≤50 or >50) copies/mL. Results - Among the 209 KS cases diagnosed during the study period, 33.2% occurred in ART naïve patients, 17.3% in ART-experienced patients and 49.5% in patients on ART, of whom 23% for more than 6 months. Among these patients, 24 (11.5%) had HIV-pVL ≤50 cp/mL, and 16 (66%) were treated with a boosted-PI-based regimen. The distribution of KS localization did not differ by ART status nor by year of diagnosis. Limitations - Data on human herpesvirus 8, treatment modalities for KS and response rate were not collected. Conclusion - Half of KS cases observed in the study period occurred in patients not on ART, reflecting the persistence of late HIV diagnosis. Factors associated with KS in patients on ART with HIV-pVL ≤50 cp/mL remain to be explored.

- Abstract
Purpose: To assess the intraocular pressure (IOP)-lowering effect of a biodegradable bimatoprost implant following selective laser trabeculoplasty (SLT) in a canine model. Methods: Unilateral SLT was performed in 11 normotensive, treatment-naive beagle dogs. IOP was measured at baseline (pre-SLT) and weekly post-SLT (≤10 weeks). After IOP returned to baseline or at 10 weeks (whichever occurred first), a sustained-release bimatoprost implant was administered bilaterally in the anterior chamber of each animal. IOP was measured weekly for 4 weeks and then every 2 weeks up to week 42. Results: The main outcomes included the IOP change (%) from baseline, calculated in both eyes in the overall population, SLT responder subgroup (defined by peak IOP reduction from baseline ≥3 mmHg or ≥15% for >1 week post-SLT), and SLT nonresponder subgroup (defined by peak IOP reduction from baseline <3 mmHg or <15%). The bimatoprost implant lowered IOP similarly in both the SLT-treated and fellow SLT-naive eyes. Following bimatoprost implant administration, the mean (standard deviation [SD]) peak IOP reduction from baseline was 34.4% (8.5%) in SLT-treated eyes and 35.7% (5.9%) in fellow SLT-naive eyes. The bimatoprost implant lowered IOP comparably ( P > 0.17) in eyes that responded to SLT (mean [SD] peak IOP reduction, 34.6% [10.7%]; n = 6) and those that did not (mean [SD] peak IOP reduction, 34.1% [6.1%]; n = 5). Conclusion: The bimatoprost implant effectively lowered IOP in eyes pretreated with SLT, regardless of response to SLT. The current data suggest that eyes previously treated with SLT can still benefit from the intracameral bimatoprost implant.

- Abstract
There is a growing demand for prehospital ambulance transport. These urgent transports however seem to be largely misused and are accompanied by risks. Several strategies have been studied with the aim of reducing demand on an already under pressure system. Sending alternative non-medical transport, a mobile nurse team or deciding not to transport a patient are some of these strategies that allow a reduction for urgent transport for non-critical patients. These various approaches bring benefits but still lack evidence regarding safety., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

- Abstract
Geographic atrophy (GA) is an advanced form of age-related macular degeneration (AMD) characterized by atrophy of the retinal pigment epithelium (RPE), loss of photoreceptors, and disruption of choriocapillaris. Excessive light exposure is toxic to the retina and is a known risk factor for AMD. We first investigated the effects of blue light-induced phototoxicity on RPE and photoreceptors in nonhuman primates (NHPs, a model of progressive retinal degeneration) and then evaluated the potential cyto- and neuroprotective effects of the brimonidine drug delivery system (Brimo DDS). In the first set of experiments related to model development, parafoveal lesions of varying severity were induced using blue light irradiation of the retina of cynomolgus monkeys to evaluate the level of phototoxicity in the RPE and photoreceptors. RPE damage was assessed using fundus autofluorescence imaging to quantify areas of hypofluorescence, while thinning of the outer nuclear layer (ONL, photoreceptor nuclei) was quantified using optical coherence tomography (OCT). Photoreceptor function was assessed using multifocal electroretinography (mfERG). RPE damage progressively increased across all lesion severities from 2 to 12 weeks, as did the extent of ONL thinning. Lesions of high severity continued to show reduction in mfERG amplitude, reaching a statistically significant maximum reduction at 12 weeks. Collectively, the first set of experiments showed that blue light irradiation of the NHP eye resulted in progressive retinal degeneration identified by damage to RPE, ONL thinning, and disrupted photoreceptor function - hallmarks of GA in humans. We then used the model to evaluate the cyto- and neuroprotective effects of Brimo DDS, administered as a therapeutic after allowing the lesions to develop for 5 weeks. Placebo DDS or Brimo DDS were administered intravitreally and a set of untreated animals were used as an additional control. In the placebo DDS group, hypofluorescence area continued to increase from baseline, indicating progressive RPE damage, while progression was significantly slowed in eyes receiving Brimo DDS. Likewise, ONL thinning continued to progress over time in eyes that received the placebo DDS, but was reduced in Brimo DDS-treated eyes. Pharmacologically relevant brimonidine concentrations were sustained in the retina for up to 26 weeks following Brimo DDS administration. In summary, Brimo DDS demonstrated cyto- and neuroprotective effects in a novel NHP GA model of progressive retinal degeneration., (Copyright © 2021 The Authors. Published by Elsevier Ltd..

- Abstract
Background and Objective: The percentage of Lebanese older people has increased considerably. Given that Lebanese seniors are marginalized in the health policy-making process, we suggest a high social inequality in oral health that has not been studied so far. The purpose of our study was to describe and compare oral health status in a group of Lebanese older people according to their socioeconomic status (SES) MATERIALS AND METHODS: Participants were recruited from three different primary health care clinics in Beirut, Lebanon. Data were collected from an administered questionnaire that included sociodemographic variables, perception of oral health, and regular dental visits. Oral examination included the number of missing and decayed teeth, the prosthetic status, and the number of functional dental units (FUs). The SES of the participants was determined by educational level, previous or actual work, and neighborhood level., Results: 264 participants aged 71.4 ± 6.27 years (64.7% female) were included in the study. Regular dental visit, dental status, FU, and oral health perception were significantly related to the participants' place of residence, educational level, and work. Moreover, the mean number of missing teeth (p = 0.048) and decayed teeth (p = 0.018) was significantly elevated in the low SES., Conclusion: There is a clear socioeconomic inequality in oral health among the Lebanese older people. Further researches should explore the potential contribution of psychosocial and behavioral factors in explaining these disparities.

Aim: The use of the ala-tragus line (ATL) to orient the occlusal plane (OP) is controversial because there is a lack of agreement on the exact points of reference for this line. This study determined the relationship between the natural OP and ATL which was established by using the inferior border of the ala of the nose and (1) the superior border of the tragus (ATL1), (2) the tip (ATL2), and (3) the inferior border of the tragus (ATL3)., Materials and Methods: Lateral cephalometric radiographs were taken of each subject by a standard method and tracings were obtained on acetate paper to show the OP and the three ala-tragus lines. The relationship between the OP and each of ATL was measured for each subject. Mean and standard deviation values were then calculated for the relationship. Statistical analysis was performed using repeated measure analysis of variance followed by Bonferroni pairwise comparisons and Student's t-test (α = 0.05)., Results: Significant differences were noted between the three mean angles (p = 0.046). The mean angle (3.275 degrees ± 2.54) formed by OP and ATL2 was significantly the smallest (p < 0.05)., Conclusion: The ala-tragus line, extending from the inferior border of the ala of the nose to the tip of the tragus of the ear presented the closest relationship to the natural occlusal plane.

- Abstract
Purpose: To compare the durability of Kenalog, Trivaris, Triesence, and compounding pharmacy preservative-free triamcinolone acetonide in pigmented rabbits with syneretic vitreous using direct visualization, pharmacodynamics, and pharmacokinetics., Methods: Twenty-five Dutch-belted rabbits were used. Pharmacokinetic experiment: Rabbits were intravitreally injected with one of four 4-mg triamcinolone acetonide formulations. Wide-field imaging was serially performed to document residual drug mass. Pharmacodynamics experiment: Four triamcinolone acetonide groups and one control group received intravitreal recombinant human vascular endothelial growth factor 165 every 2 weeks and were followed with fluorescein angiography to assess vascular endothelial growth factor retinal vasculopathy as a measure of residual steroid effect. Particle size of the formulations was measured with Mastersizer 2000., Results: Remaining triamcinolone acetonide mass after 19 weeks: 12,091 ± 2,512 pixels for the Kenalog group, 1,307.36 ± 695.57 for Trivaris, 5577 ± 1477 for Triesence, and 1,535 ± 329 for compounded preservative-free triamcinolone acetonide. Kenalog suppressed recombinant human vascular endothelial growth factor-induced retinopathy more effectively than the other triamcinolone acetonide groups at Week 39, the final time point assessed. Particle size (90th percentile) was 47 μm for Kenalog, 26 μm for Triesence, and 22 μm for both compounded preservative-free triamcinolone acetonide and Trivaris., Conclusion: Triamcinolone acetonide formulations do not have the same pharmacokinetics/pharmacodynamics. Kenalog has the longest vitreous visibility and durability. Particle size appears to correlate with efficacy and durability.

- Abstract
Purpose. Pars plana vitrectomy (PPV) has been reported to reduce macular thickness and improve visual acuity in patients with diabetic macular edema (ME). The hypothesis for the study was that after PPV, clearance is accelerated and VEGF concentrations are reduced. To test this hypothesis, hVEGF(165) injections were performed in rabbit eyes, with and without PPV, and vitreous VEGF levels were measured as a function of time. Methods. The PPV group rabbits had a bilateral 25-gauge PPV, and in the no-PPV group, rabbits had intact vitreous. Intravitreal injections of hVEGF(165) were performed, and the animals were euthanatized at time points up to 7 days. The vitreous was isolated and an enzyme-linked immunosorbent assay was used to measure the VEGF levels. Pharmacokinetic parameters were determined in a noncompartmental analysis approach. Results. Mean vitreous VEGF levels decreased more rapidly in eyes subjected to PPV than in no-PPV eyes. The vitreous VEGF half-life (t([)(1/2)(])) in PPV eyes was 10 times shorter than that in normal eyes. In addition, mean clearance and mean area under the curve (AUC) increased and decreased, respectively, in eyes that underwent PPV. Conclusions. VEGF clearance is increased after PPV. Reducing VEGF concentrations in the vitreous post-PPV may partially explain the improvement in macular thickness in some patients with ME. Unexpectedly, the half-life of VEGF in the vitreous, even in no-PPV eyes, was <3 hours, whereas compounds of similar molecular weight typically have longer vitreous half-lives. The back of the eye may be uniquely adapted with rapid-clearance mechanisms to regulate vitreous VEGF levels. Further study is suggested.

- Abstract
Introduction: To reduce the polymerization shrinkage of the composite resins and after the introduction of the "slow and gradual polymerization" by GORACCI et al. in 1992, many light curing units (LCU) presented the "soft-start polymerization" in addition to the classical high light intensity mode. This study investigated whether this slow and gradual polymerization has the ability of reducing the marginal debonding, by minimizing the internal stress of the composite, knowing that rare are the studies which compared this mode of polymerization., Material and Methods: One hundred twenty Class II cavities were prepared at the mesial and the distal side of human extracted premolars. The teeth were randomly divided into four groups (n = 15). In each tooth the mesial Class II cavities were restored with the micro-hybrid resin composite Filtek Z250 (3M ESPE) and the distal Class II cavities were restored with the nano-filled resin composite Filtek Supreme (3M ESPE). The light curing unit used in this study was a conventional quartz tungsten halogen (QTH) curing light, the QHL 75 (Dentsply) modified by adding a regulating electronic device, controlled by a special software that gives 4 different modes of polymerization as follows: Group A: Standard polymerization: Exposure for 20 seconds at 700 mW/cm2, this group was used as control. Group B: Modified pulse-delay polymerization: Exposure for 2 seconds at 700 mW/cm2, 5 seconds at 0 mW/cm2, then 20 seconds at 700mW/cm2. Group C: Modified ramp polymerization: Exposure for 20 seconds with a slow rise of the intensity to reach the 700 mW/cm2 then 20 seconds at 700 mW/cm2. Group D: Slow and Gradual polymerization: Exposure for 4 minutes with a slow rise of the intensity to reach 700 mW/cm2. The teeth were stored in water at 37 degrees C for 48 hours, then finished and subjected to thermocycling (3000 cycles between 5 degrees C and 55 degrees C). All the teeth were immersed in 2% methylene blue solution for 12 hours at 37 degrees C, sectioned, and evaluated at the gingival margins. Data were statistically analyzed by two-way analysis of variance followed by Tukey HSD multiple comparisons., Results: The main effect for the type of composites (p = 0.682), and the interaction effect (p = 0.678) did not reach statistical significance. There was a statistically significant main effect for the type of polymerization used (p = 0.014). Post-hoc comparisons using the Tukey HSD test indicated that the mean score for the Group A (M = 2.40, SD = 1.102) was significantly different from the group D (M = 1.30, SD = 1.393, p = 0.010). The group D did not differ significantly from group B (M = 1.63, SD = 1.351, p = 0.767), and group C (M = 1.60, SD = 1.404, p = 0.819). There was a difference between the group A (M = 2.40, SD = 1.102), group B (M = 1.63, SD = 1.351) and group C (M = 1.60, SD = 1.404). However, when the Tukey HSD was used, no statistically significant differences between Group A, B and C were found (p = 0.122 and p = 0.098)., Conclusions: There was a statistically significant difference in microleakage between the "slow and gradual polymerization" and the standard polymerization, however no significant differences were found when using the nano-filled or the micro-hybrid composite materials cured with different polymerization regimens.

- Abstract
Agonists of retinoid X receptors (RXRs), which include the natural 9-cis-retinoic acid and synthetic analogs, are potent inducers of growth arrest and apoptosis in some cancer cells. As such, they are being used in clinical trials for the treatment and prevention of solid tumors and are used to treat cutaneous T cell lymphoma. However, the molecular mechanisms that underlie the anti-cancer effects of RXR agonists remain unclear. Here, we show that a novel pro-apoptotic pathway that is induced by RXR agonist is negatively regulated by casein kinase 1alpha (CK1alpha). CK1alpha associates with RXR in an agonist-dependent manner and phosphorylates RXR. The ability of an RXR agonist to recruit CK1alpha to a complex with RXR in cells correlates inversely with its ability to inhibit growth. Remarkably, depletion of CK1alpha in resistant cells renders them susceptible to RXR agonist-induced growth inhibition and apoptosis. Our study shows that CK1alpha can promote cell survival by interfering with RXR agonist-induced apoptosis. Inhibition of CK1alpha may enhance the anti-cancer effects of RXR agonists.

- Abstract
Beta-catenin is a component of stable cell adherent complexes whereas its free form functions as a transcription factor that regulate genes involved in oncogenesis and metastasis. Free beta-catenin is eliminated by two adenomatous polyposis coli (APC)-dependent proteasomal degradation pathways regulated by glycogen synthase kinase 3beta (GSK3 beta) or p53-inducible Siah-1. Dysregulation of beta-catenin turnover consequent to mutations in critical genes of the APC-dependent pathways is implicated in cancers such as colorectal cancer. We have identified a novel retinoid X receptor (RXR)-mediated APC-independent pathway in the regulation of beta-catenin. In this proteasomal pathway, RXR agonists induce degradation of beta-catenin and RXR alpha and repress beta-catenin-mediated transcription. In vivo, beta-catenin interacts with RXR alpha in the absence of ligand, but RXR agonists enhanced the interaction. RXR agonist action was not impaired by GSK3 beta inhibitors or deletion of the GSK3 beta-targeted sequence from beta-catenin. In APC- and p53-mutated colorectal cancer cells, RXR agonists still inactivated endogenous beta-catenin via RXR alpha. Interestingly, deletion of the RXR alpha A/B region abolished ligand-induced beta-catenin degradation but not RXR alpha-mediated transactivation. RXR alpha-mediated inactivation of oncogenic beta-catenin paralleled a reduction in cell proliferation. These results suggest a potential role for RXR and its agonists in the regulation of beta-catenin turnover and related biological events.

- Abstract
Retinoids, synthetic and natural analogs of retinoic acid, exhibit potent growth inhibitory and cell differentiation activities that account for their beneficial effects in treating hyperproliferative diseases such as psoriasis, actinic keratosis, and certain neoplasias. Tazarotene is a synthetic retinoid that is used in the clinic for the treatment of psoriasis. To better understand the mechanism of retinoid action in the treatment of hyperproliferative diseases, we used a long-range differential display-PCR to isolate retinoid-responsive genes from primary human keratinocytes. We have identified a cDNA, tazarotene-induced gene 3 (TIG3; Retinoic Acid Receptor Responder 3) showing significant homology to the class II tumor suppressor gene, H-rev 107. Tazarotene treatment increases TIG3 expression in primary human keratinocytes and in vivo in psoriatic lesions. Increased TIG3 expression is correlated with decreased proliferation. TIG3 is expressed in a number of tissues, and expression is reduced in cancer cell lines and some primary tumors. In breast cancer cell lines, retinoid-dependent TIG3 induction is observed in lines that are growth suppressed by retinoids but not in nonresponsive lines. Transient over-expression of TIG3 in T47D or Chinese hamster ovary cells inhibits colony expansion. Finally, studies in 293 cells expressing TIG3 linked to an inducible promoter demonstrated decreased proliferation with increased TIG3 levels. These studies suggest that TIG3 may be a growth regulator that mediates some of the growth suppressive effects of retinoids.

- Abstract
Purpose: The exact etiology of dry eye is unknown but is believed to be multifactorial. Apoptosis has been implicated in the pathogenesis of autoimmune diseases such as Sjögren's syndrome (SS). This study attempted to gain a better understanding of the role of apoptosis and its regulation in the patho-physiology of dry eye. The therapeutic effect of immunomodulatory agents such as cyclosporin A (CsA) in the treatment of dry eye, particularly its impact on the level of apoptosis in the target tissues, is also investigated., Methods: A colony of dogs with spontaneous chronic idiopathic keratoconjunctivitis sicca (KCS) was maintained. Nictitans lacrimal gland (NLG), an accessory lacrimal gland, and conjunctival biopsies of the KCS and normal dogs were obtained before and after 12 weeks of treatment with 0.2% topical CsA ophthalmic emulsion b.i.d. (Allergan, Inc., Irvine, CA, U.S.A.). Tissues were prepared for the terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL) apoptosis assay and immunohistochemical analysis for various apoptosis mediators., Results: The TUNEL assay demonstrated that (i) the normal NLG and conjunctival epithelial cells exhibited a limited level of apoptosis; (ii) in KCS dogs, lacrimal acinar and conjunctival epithelial cells underwent an increased apoptosis, whereas the lymphocytes had a significantly lower level of apoptosis compared to those of the normal dogs; (iii) after topical CsA, apoptosis was induced in the lymphocytes and suppressed in the acinar and conjunctival epithelial cells in KCS dogs. Immunohistochemistry revealed that p53, fas, and fasL, but not bcl-2 were highly expressed in the target tissues of KCS dogs. The immunoreactivity of p53 was significantly decreased, whereas the bcl-2 level was increased after CsA administration., Conclusions: The induction of epithelial cell apoptosis and the suppression of lymphocytic apoptosis in the NLG and ocular-surface tissues, such as conjunctiva of KCS dogs, indicates the important role of this phenomenon in the etiology of dry eye. Topical CsA appears to facilitate lymphocytic apoptosis and suppress epithelial cell apoptosis in the KCS dog. The differential expression of various apoptotic mediators after topical treatment implicates CsA in facilitating the reestablishment of the normal apoptotic balance, suggesting additional mechanisms by which CsA is therapeutic for dry-eye syndrome.

- Abstract
Retinoids exert their biologic effects through two families of nuclear receptors, retinoic acid receptors (RARs) and retinoid X receptors (RXRs), which belong to the superfamily of steroid/thyroid hormone nuclear receptors. By using a subtraction hybridization approach, we have identified a cDNA sequence TIG2 (Tazarotene-induced gene 2), whose expression is up-regulated by the treatment of skin raft cultures by an RAR beta/gamma-selective anti-psoriatic synthetic retinoid tazarotene [AGN 190168/ethyl 6-[2-(4,4-dimethylthiochroman-6-yl)-ethynyl] nicotinate]. The retinoid-mediated up-regulation in the expression of TIG2 was confirmed by Northern blot analysis. Upon sequencing, TIG2 was found to be a cDNA whose complete sequence was not in the GenBank and EMBL data bases. The TIG2 cDNA is 830 bp long and encodes a putative protein product of 164 amino acids. TIG2 is neither expressed nor induced by tazarotene in primary keratinocyte and fibroblast cultures. Thus, TIG2 is expressed and induced by tazarotene only when keratinocytes and fibroblasts form a tissue-like 3-dimensional structure. We further demonstrate that RAR-specific retinoids increase TIG2 mRNA levels. In contrast, neither RXR-specific retinoids nor 1,25-dihydroxyvitamin D3 increased TIG2 levels. Finally, we demonstrate that TIG2 is expressed at high levels in nonlesional psoriatic skin but at lower levels in the psoriatic lesion and that its expression is up-regulated in psoriatic lesions after topical application of tazarotene.

- Abstract
Human recombinant platelet-derived growth factor was evaluated with the use of wound healing models in New Zealand albino rabbits. The efficacy of the platelet-derived growth factor dimers, AA, AB, and BB, was determined in corneal reepithelialization and anterior keratectomy models which examined the healing response in the presence or absence of the basement membrane. All dimers increased the rate of wound healing in both models at 100 microg/ml when compared with control; however, the platelet-derived growth factor-BB isoform showed the most dramatic increase in both studies. The strength of the healing stroma after incision was evaluated by means of a tensile strength model. Histologic evaluation of the stromal wound area after 9 days of healing showed a marked increase in the number of keratocytes within the wound bed of the corneas treated with platelet-derived growth factor-BB when compared with control corneas. In addition, at 9 days, the epithelial plug was still present in the control corneas but had been extruded to the surface by the granulation tissue in the platelet-derived growth factor-BB-treated corneas. These results are indicative of a more advanced stage of healing in treated versus control wounds at 9 days after the operation. A 30% increase in corneal tensile strength versus control was noted after 21 days of healing. Finally, in an in vitro gel contraction assay, platelet-derived growth factor exhibited a dose-dependent effect on the contraction of fibroblasts for doses ranging from 0.01 to 10 ng/ml. These results indicate that platelet-derived growth factor is active in the corneal wound healing process.

- Abstract
By sequence analysis of genomic clones, the exon-intron structure of one of the two src genes from Xenopus laevis has been determined. The coding region of the gene is interrupted by 10 introns whose locations are identical to the introns in the coding regions of the src genes of human and chicken. The 5' untranslated region is contained on a separate exon with no sequence conservation relative to the corresponding region of the chicken gene. The 5' untranslated region of the Xenopus gene contains a G + C-rich stem-loop sequence and two ATG triplets. A 1.4-kb fragment containing the 5' untranslated region and sequences upstream of it acts as a promoter when introduced in the correct orientation into X. laevis cell lines. The DNA sequence of this fragment lacks the typical arrangement of TATA and CCAAT sequences but contains the ATGCAAAT octamer sequence and a (TA)39 sequence.

- Abstract
We have undertaken a molecular analysis of the salivary glands of hematophagous insects in order to better understand their role in blood feeding and in the transmission of infectious diseases. To that end, genomic and cDNA clones of a gene designated D7, expressed abundantly in the adult female salivary glands of the vector mosquito aegypti, have been isolated and characterized. This gene encodes a mRNA shown by Northern analysis and in situ hybridization to tissue sections to be specifically transcribed in the distal-lateral and medial lobes of the glands, regions that are highly differentiated in females. The deduced gene product, a protein of approximately 37 kDa appears to be novel. Polyclonal antibodies made to a recombinant D7 product recognize a protein with the proper molecular weight in female salivary glands and saliva. These studies indicate that the D7 gene probably encodes the major secreted protein synthesized in the female salivary glands. The stage- and sex-limited expression of the D7 gene, and the secretion of its product, indicate that the product is most likely involved with the blood feeding capabilities of the female mosquito.

- Abstract
By low stringency screening of a Xenopus laevis oocyte cDNA library with a probe prepared from the yes oncogene of the avian retrovirus Y73, we have isolated clones encoding a 537 amino acid protein with 96% amino acid identity to the protein product of the human fyn proto-oncogene. In addition to the high degree of conservation at the amino acid sequence level, we also find a surprisingly high degree of sequence conservation between portions of the 5' untranslated regions of the frog and human genes. Probing of total DNA from a homozygous diploid frog with a fragment from one of the cDNA clones gave a hybridization pattern which is consistent with the presence of two fyn genes in the haploid Xenopus laevis genome. Hybridization analysis revealed that the ovary contains two different sized fyn RNAs, one 3.8 kb in length and the other 3.1 kb in length. Our finding of fyn transcripts brings to three the number of protein-tyrosine kinases of the src family whose mRNAs are found in X. laevis oocytes. This suggests that multiple protein-tyrosine kinases of the src family are required for processes in oogenesis or early development.
