Abstract

Lipofuscin (LF) accumulates during lifetime in the retinal pigment epithelium (RPE) and is thought to play a crucial role in intermediate and late age-related macular degeneration (AMD). In an attemt to simulate aged retina and to study response of retinal microglia and RPE cells to LF, we injected a suspension of LF into the subretinal space of adult mice. LF suspension was obtained from human donor eyes. Subretinal injection of PBS or sham injection served as a control. Eyes were inspected by autofluorescence and optical coherence tomography, by electroretinography and on histological and ultrastructural levels. Levels of cytokine mRNA were determined by quantitative PCR separately in the RPE/choroid complex and in the retina. After injection of LF, microglial cells migrated quickly into the subretinal space to close proximity to RPE cells and phagocytosed LF particles. Retinal function was affected only slightly by LF within the first two weeks. After longer time, RPE cells showed clear signs of melanin loss and degradation. Levels of mRNA of inflammatory cytokines increased sharply after injection of both PBS and LF and were higher in the RPE/choroid complex than in the retina and were slightly higher after LF injection. In conclusion, subretinal injection of LF causes an activation of microglial cells and their migration into subretinal space, enhanced expression of inflammatory cytokines and a gradual degradation of RPE cells. These features are found also in an aging retina, and subretinal injection of LF could be a model for intermediate and late AMD, Finanziert durch den Open-Access-Publikationsfonds der Westfälischen Wilhelms-Universität Münster (WWU Münster).

Abstract

Amplification of the gene encoding cyclin E (CCNE1) is an oncogenic driver in several malignancies and is associated with chemoresistance and poor prognosis. To uncover therapeutic targets forCCNE1-amplified tumors, we undertook genome-scale CRISPR/Cas9-based synthetic lethality screens in cellular models ofCCNE1amplification. Here, we report that increasingCCNE1dosage engenders a vulnerability to the inhibition of the PKMYT1 kinase, a negative regulator of CDK1. To inhibit PKMYT1, we developed RP-6306, an orally bioavailable and selective inhibitor that shows single-agent activity and durable tumor regressions when combined with gemcitabine in models ofCCNE1-amplification. RP-6306 treatment causes unscheduled activation of CDK1 selectively inCCNE1overexpressing-cells, promoting early mitosis in cells undergoing DNA synthesis.CCNE1overexpression disrupts CDK1 homeostasis at least in part through an early activation of the FOXM1/MYBL2/MuvB-dependent mitotic transcriptional program. We conclude that PKMYT1 inhibition is a promising therapeutic strategy forCCNE1-amplified cancers.

Abstract

International audience; Non-digestible milk oligosaccharides were proposed as receptor decoys ă for pathogens and as nutrients for beneficial gut commensals like ă bifidobacteria. Bovine milk contains oligosaccharides, some of which are ă structurally identical or similar to those found in human milk. In a ă controlled, randomized double-blinded clinical trial we tested the ă effect of feeding a formula supplemented with a mixture of bovine ă milk-derived oligosaccharides (BMOS) generated from whey permeate, ă containing galacto-oligosaccharides and 3'- and 6'-sialyllactose, and ă the probiotic Bifidobacterium animalis subsp. lactis (B.lactis) strain ă CNCM I-3446. Breastfed infants served as reference group. Compared with ă a non-supplemented control formula, the test formula showed a similar ă tolerability and supported a similar growth in healthy newborns followed ă for 12 weeks. The control, but not the test group, differed from the ă breast-fed reference group by a higher faecal pH and a significantly ă higher diversity of the faecal microbiota. In the test group the ă probiotic B.lactis increased by 100-fold in the stool and was detected ă in all supplemented infants. BMOS stimulated a marked shift to a ă bifidobacterium-dominated faecal microbiota via increases in endogenous ă bifidobacteria (B.longum, B.breve, B.bifidum, B.pseudocatenulatum).

Abstract

Objective: To test the a priori hypothesis that longer duration of ruptured membranes is associated with increased risk of vertical transmission of HIV. Design: The relationship between duration of ruptured membranes and vertical transmission of HIV was evaluated in an individual patient data meta-analysis. Methods: Eligible studies were prospective cohort studies including at least 100 mother-child pairs, from regions where HIV-infected women are counselled not to breastfeed. Analyses were restricted to vaginal deliveries and non-elective Cesarean sections; elective Cesarean section deliveries (those performed before onset of labour and before rupture of membranes) were excluded. Results: The primary analysis included 4721 deliveries with duration of ruptured membranes ≤ 24 h. After adjusting for other factors known to be associated with vertical transmission using logistic regression analysis to assess the strength of the relationship, the risk of vertical HIV transmission increased approximately 2% with an increase of 1 h in the duration of ruptured membranes [adjusted odds ratio, 1.02; 95% confidence interval, 1.01-1.04; for each 1 h increment]. There were no significant interactions of duration of ruptured membranes with study cohort or with any of the covariates, except maternal AIDS. Among women diagnosed with AIDS, the estimated probability of transmission increased from 8% to 31% with duration of ruptured membranes of 2 h and 24 h respectively (P < 0.01). Conclusions: These results support the importance of duration of ruptured membranes as a risk factor for vertical transmission of HIV and suggest that a diagnosis of AIDS in the mother at the time of delivery may potentiate the effect of duration of ruptured membranes. © 2001 Lippincott Williams & Wilkins.

In a controlled, randomized double-blinded clinical trial we tested the effect of feeding a formula supplemented with a mixture of bovine milk-derived oligosaccharides (BMOS) generated from whey permeate, containing galacto-oligosaccharides and 3'- and 6'-sialyllactose, and the probiotic Bifidobacterium animalis subsp. lactis (B. lactis) strain CNCM I-3446. Breastfed infants served as reference group. Compared with a non-supplemented control formula, the test formula showed a similar tolerability and supported a similar growth in healthy newborns followed for 12 weeks. The control, but not the test group, differed from the breast-fed reference group by a higher faecal pH and a significantly higher diversity of the faecal microbiota. In the test group the probiotic B. lactis increased by 100-fold in the stool and was detected in all supplemented infants. BMOS stimulated a marked shift to a bifidobacterium-dominated faecal microbiota via increases in endogenous bifidobacteria (B. longum, B. breve, B. bifidum, B. pseudocatenulatum).

Abstract

Background To evaluate the relation between elective cesarean section and vertical transmission of human immunodeficiency virus type 1 (HIV-1), we performed a meta-analysis using data on individual patients from 15 prospective cohort studies. Methods North American and European studies of at least 100 mother-child pairs were included in the meta-analysis. Uniform definitions of modes of delivery were used. Elective cesarean sections were defined as those performed before onset of labor and rupture of membranes. Multivariate logistic-regression analysis was used to adjust for other factors known to be associated with vertical transmission. Results The primary analysis included data on 8533 mother-child pairs. After adjustment for receipt of antiretroviral therapy, maternal stage of disease, and infant birth weight, the likelihood of vertical transmission of HIV-1 was decreased by approximately 50 percent with elective cesarean section, as compared with other modes of delivery (adjusted odds ratio, 0.43; 95 percent confidence interval, 0.33 to 0.56). The results were similar when the study population was limited to those with rupture of membranes shortly before delivery. The likelihood of transmission was reduced by approximately 87 percent with both elective cesarean section and receipt of antiretroviral therapy during the prenatal, intrapartum, and neonatal periods, as compared with other modes of delivery and the absence of therapy (adjusted odds ratio, 0.13; 95 percent confidence interval, 0.09 to 0.19). Among mother-child pairs receiving antiretroviral therapy during the prenatal, intrapartum, and neonatal periods, rates of vertical transmission were 2.0 percent among the 196 mothers who underwent elective cesarean section and 7.3 percent among the 1255 mothers with other modes of delivery. Conclusions The results of this meta-analysis suggest that elective cesarean section reduces the risk of transmission of HIV-1 from mother to child independently of the effects of treatment with zidovudine.

Abstract

To evaluate the relation between elective cesarean section and vertical transmission of human immunodeficiency virus type 1 (HIV-1), we performed a meta-analysis using data on individual patients from 15 prospective cohort studies. North American and European studies of at least 100 mother-child pairs were included in the meta-analysis. Uniform definitions of modes of delivery were used. Elective cesarean sections were defined as those performed before onset of labor and rupture of membranes. Multivariate logistic-regression analysis was used to adjust for other factors known to be associated with vertical transmission. The primary analysis included data on 8533 mother-child pairs. After adjustment for receipt of antiretroviral therapy, maternal stage of disease, and infant birth weight, the likelihood of vertical transmission of HIV-1 was decreased by approximately 50 percent with elective cesarean section, as compared with other modes of delivery (adjusted odds ratio, 0.43; 95 percent confidence interval, 0.33 to 0.56). The results were similar when the study population was limited to those with rupture of membranes shortly before delivery. The likelihood of transmission was reduced by approximately 87 percent with both elective cesarean section and receipt of antiretroviral therapy during the prenatal, intrapartum, and neonatal periods, as compared with other modes of delivery and the absence of therapy (adjusted odds ratio, 0.13; 95 percent confidence interval, 0.09 to 0.19). Among mother-child pairs receiving antiretroviral therapy during the prenatal, intrapartum, and neonatal periods, rates of vertical transmission were 2.0 percent among the 196 mothers who underwent elective cesarean section and 7.3 percent among the 1255 mothers with other modes of delivery. The results of this meta-analysis suggest that elective cesarean section reduces the risk of transmission of HIV-1 from mother to child independently of the effects of treatment with zidovudine.

Abstract

Non-digestible milk oligosaccharides were proposed as receptor decoys for pathogens and as nutrients for beneficial gut commensals like bifidobacteria. Bovine milk contains oligosaccharides, some of which are structurally identical or similar to those found in human milk. In a controlled, randomized double-blinded clinical trial we tested the effect of feeding a formula supplemented with a mixture of bovine milk-derived oligosaccharides ( BMOS) generated from whey permeate, containing galacto-oligosaccharides and 3'- and 6'-sialyllactose, and the probiotic B ifidobacterium animalis subsp. lactis ( B . lactis) strain CNCM I-3446. Breastfed infants served as reference group. Compared with a non-supplemented control formula, the test formula showed a similar tolerability and supported a similar growth in healthy newborns followed for 12 weeks. The control, but not the test group, differed from the breast-fed reference group by a higher faecal pH and a significantly higher diversity of the faecal microbiota. In the test group the probiotic B . lactis increased by 100-fold in the stool and was detected in all supplemented infants. BMOS stimulated a marked shift to a bifidobacterium-dominated faecal microbiota via increases in endogenous bifidobacteria ( B . longum, B . breve, B . bifidum, B . pseudocatenulatum).

Abstract

Twenty-four perinatally HIV infected children received early treatment as soon as the diagnosis of viral contamination was established. In 13 cases (group 1), this diagnosis was based on a viremia and/or antigenemia during the first 6 months of life. In 11 cases (group 2), children were more than 15 months-old and had a positive HIV antibody test. Therapy included azidothymidine (AZT, 400 mg/m2/d) and the prevention of secondary infectious complications with intravenous immunoglobulin and cotrimoxazole. With a median follow-up of 26 months, we reported no case of severe secondary infection and no case of encephalopathy. Hematological side effects of AZT were rarely observed. Only one patient developed anemia. In all other cases, the only hematological abnormality was macrocytosis of red blood cells. Before treatment, the mean value of T4 cells age-adjusted count was 96, 86 and 91%, respectively, for groups 1, 2 and the entire study group. At the time of analysis, these values were 64, 62 and 63% respectively. This decrease was statistically significant for group 1 and for the entire study group, but did not reach statistical significance for group 2. These data show that AZT is probably insufficient as a long-term therapy for HIV infected children. Other therapeutic approaches need to be developed in the future, notably the combination of anti-retroviral drugs.

24. Phenotypic plasticity and nutrition in a phytophagous insect: consequences of colonizing a new host

Author

Leclaire, M., Brandl, R., Leclaire, M., and Brandl, R.

Abstract

The European rose-hip fruit fly Rhagoletis alternata (Diptera, Tephritidae) infests hips of Rosa species. This fly includes R. rugosa, an Asian species now cultivated all over Europe, in its host range. Differences in size and biomass of hips between the ancestral host R. canina and the new host translate into better growth, shorter larval development of larvae within hips of R. rugosa and larger body size and fertility of flies which developing in the new host. In turn this causes different interactions with other organisms of the food-web centred on the host plant. The importance of nutrition and phenotypic plasticity is twofold: they generate a considerable part of life-history diversity within a species and reinforce differences in the ecological context of the ancestral and new host.

Abstract

How far providing neonatal intensive care to extremely low birth weight infants is appropriate is still a highly controversial issue. Decision making when a poor prognosis has been established may be facilitated by consensus based recommendations and rigorous procedures. In the very majority of situations, the provision of intensive care is advocated at birth a priori. A decision of treatment withholding or withdrawal may eventually be made secondarily, in the case major neurological complications, likely to induce severe long term deficits, are evidenced. In any case, an ethical policy focused on each infant's best interest is justified, while the adoption of a systematic, gestational age or birth weight based restriction of access to intensive care may not be acceptable in most countries. Rigorous criteria must be fulfilled for end of life decision making and procedures. Continuous assistance to the patient and to the parents is key determinant.

Abstract

Background: Peer support has been extensively studied in specific areas of community-based primary care such as mental health, substance use, HIV, homelessness, and Indigenous health. These programs are often built on the assumption that peers must share similar social identities or lived experiences of disease to be effective. However, it remains unclear how peers can be integrated in general primary care setting that serves people with a diversity of health conditions and social backgrounds., Methods: A participatory qualitative study was conducted between 2020 and 2022 to explore the feasibility, acceptability, and perceived effects of the integration of a peer support worker in a primary care setting in Montreal, Canada. A thematic analysis was performed based on semi-structured interviews (n = 18) with patients, relatives, clinicians, and a peer support worker., Findings: Findings show that peers connect with patients through sharing their own hardships and how they overcame them, rather than sharing similar health or social conditions. Peers provide social support and coaching beyond the care trajectory and link identified needs with available resources in the community, bridging the gap between health and social care. Primary care clinicians benefit from peer support work, as it helps overcome therapeutic impasses and facilitates communication of patient needs. However, integrating a peer into a primary care team can be challenging due to clinicians' understanding of the nature and limits of peer support work, financial compensation, and the absence of a formal status within healthcare system., Conclusion: Our results show that to establish a relationship of trust, a peer does not need to share similar health or social conditions. Instead, they leverage their experiential knowledge, strengths, and abilities to create meaningful relationships and reliable connections that bridge the gap between health and social care. This, in turn, instills patients with hope for a better life, empowers them to take an active role in their own care, and helps them achieve life goals beyond healthcare. Finally, integrating peers in primary care contributes in overcoming obstacles to prevention and care, reduce distrust of institutions, prioritize needs, and help patients navigate the complexities of healthcare services., (© 2024.

50. O-GlcNAcylation of FOXK1 orchestrates the E2F pathway and promotes oncogenesis.

Abstract

Gene transcription is a highly regulated process, and deregulation of transcription factors activity underlies numerous pathologies including cancer. Albeit near four decades of studies have established that the E2F pathway is a core transcriptional network that govern cell division in multi-cellular organisms 1,2 , the molecular mechanisms that underlie the functions of E2F transcription factors remain incompletely understood. FOXK1 and FOXK2 transcription factors have recently emerged as important regulators of cell metabolism, autophagy and cell differentiation 3-6 . While both FOXK1 and FOXK2 interact with the histone H2AK119ub deubiquitinase BAP1 and possess many overlapping functions in normal biology, their specific functions as well as deregulation of their transcriptional activity in cancer is less clear and sometimes contradictory 7-13 . Here, we show that elevated expression of FOXK1, but not FOXK2, in primary normal cells promotes transcription of E2F target genes associated with increased proliferation and delayed entry into cellular senescence. FOXK1 expressing cells are highly prone to cellular transformation revealing important oncogenic properties of FOXK1 in tumor initiation. High expression of FOXK1 in patient tumors is also highly correlated with E2F gene expression. Mechanistically, we demonstrate that FOXK1, but not FOXK2, is specifically modified by O-GlcNAcylation. FOXK1 O-GlcNAcylation is modulated during the cell cycle with the highest levels occurring during the time of E2F pathway activation at G1/S. Moreover, loss of FOXK1 O-GlcNAcylation impairs FOXK1 ability to promote cell proliferation, cellular transformation and tumor growth. Mechanistically, expression of FOXK1 O-GlcNAcylation-defective mutants results in reduced recruitment of BAP1 to gene regulatory regions. This event is associated with a concomitant increase in the levels of histone H2AK119ub and a decrease in the levels of H3K4me1, resulting in a transcriptional repressive chromatin environment. Our results define an essential role of O-GlcNAcylation in modulating the functions of FOXK1 in controlling the cell cycle of normal and cancer cells through orchestration of the E2F pathway., Competing Interests: Competing interests The authors declare no conflict of interest
