Abstract

BACKGROUND: Atrial fibrillation is the most common cardiac arrhythmia, and no current therapy is ideal for control of this condition. Experimental studies suggest that angiotensin II-receptor blockers (ARBs) can influence atrial remodeling, and some clinical studies suggest that they may prevent atrial fibrillation. METHODS: We conducted a large, randomized, prospective, placebo-controlled, multicenter trial to test whether the ARB valsartan could reduce the recurrence of atrial fibrillation. We enrolled patients who were in sinus rhythm but had had either two or more documented episodes of atrial fibrillation in the previous 6 months or successful cardioversion for atrial fibrillation in the previous 2 weeks. To be eligible, patients also had to have underlying cardiovascular disease, diabetes, or left atrial enlargement. Patients were randomly assigned to receive valsartan or placebo. The two primary end points were the time to a first recurrence of atrial fibrillation and the proportion of patients who had more than one recurrence of atrial fibrillation over the course of 1 year. RESULTS: A total of 1442 patients were enrolled in the study. Atrial fibrillation recurred in 371 of the 722 patients (51.4%) in the valsartan group, as compared with 375 of 720 (52.1%) in the placebo group (adjusted hazard ratio, 0.97; 96% confidence interval [CI], 0.83 to 1.14; P = 0.73). More than one episode of atrial fibrillation occurred in 194 of 722 patients (26.9%) in the valsartan group and in 201 of 720 (27.9%) in the placebo group (adjusted odds ratio, 0.89; 99% CI, 0.64 to 1.23; P = 0.34). The results were similar in all predefined subgroups of patients, including those who were not receiving angiotensin-converting-enzyme inhibitors. CONCLUSIONS: Treatment with valsartan was not associated with a reduction in the incidence of recurrent atrial fibrillation. (ClinicalTrials.gov number, NCT00376272.)

Abstract

Spleen tyrosine kinase (Syk) is a key signal transduction mediator of the B cell receptor (BCR) signaling pathway. Abnormal BCR signaling plays a key role in initiation and development of B-cell-derived hematological malignancies, therefore, Syk represents a potential target for inhibiting the BCR signaling resulting in a therapeutic effect in these cancers. Herein, we describe a novel series of SYK inhibitors with 4-(3'-pyrazolyl)-2-amino-pyrimidine scaffold. Extensive study of structure-activity relationships led to the identification of 1 (NMS-0963), a highly potent Syk inhibitor (IC 50  = 3 nM) endowed with high selectivity within a panel of tested kinases and high antiproliferative activity in SYK-dependent BaF3-TEL/SYK cells and in other BCR-dependent hematological tumor cell lines. Additionally, 1 effectively inhibited Syk phosphorylation and downstream signaling mediators of the BCR in treated cells. In in vivo pharmacokinetics studies, 1, displayed good pharmacokinetics properties, with linear exposure with dose and excellent oral bioavailability. These findings suggest that 1 is a promising new Syk inhibitor for treating BCR-dependent hematological cancers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Abstract

Platypnea-orthodeoxia syndrome is a rare disorder characterized by dyspnea and oxygen desaturation in upright position, with improvement of symptoms and blood oxygenation in supine position. Basically a right-to-left shunt (intracardiac or pulmonary) or a ventilation/perfusion mismatch are necessary to develop platypnea-orthodeoxia syndrome. Atrial septal defects, including patent foramen ovale (PFO), are known to be a frequent cause of platypnea-orthodeoxia syndrome. We describe herein the case of a 79-year-old woman with platypnea-orthodeoxia syndrome and PFO who developed a refractory worsening respiratory failure. Only the "rescue" emergency closure of PFO allowed the patient a clinical turning point with immediate and sustained respiratory improvement.

Abstract

Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase responsible for the development of different tumor types. Despite the remarkable clinical activity of crizotinib (Xalkori), the first ALK inhibitor approved in 2011, the emergence of resistance mutations and of brain metastases frequently causes relapse in patients. Within our ALK drug discovery program, we identified compound 1, a novel 3-aminoindazole active on ALK in biochemical and in cellular assays. Its optimization led to compound 2 (entrectinib), a potent orally available ALK inhibitor active on ALK-dependent cell lines, efficiently penetrant the blood-brain barrier (BBB) in different animal species and highly efficacious in in vivo xenograft models. Moreover, entrectinib resulted to be strictly potent on the closely related tyrosine kinases ROS1 and TRKs recently found constitutively activated in several tumor types. Entrectinib is currently undergoing phase I/II clinical trial for the treatment of patients affected by ALK-, ROS1-, and TRK-positive tumors.

Abstract

The link between breast cancer and estrogen receptor (ER) is well established. The ER is a hormone-inducible transcription factor that, upon binding to its ligand, regulates the expression of a variety of genes mainly involved in cell proliferation and differentiation. Coactivators are proteins recruited by the hormone-activated receptor, which allow or enhance the ER transactivation functions by acting as chromatin remodeling enzymes or adaptors between ER and the transcriptional machinery. Our laboratory has previously identified the WW-domain binding protein-2 (WBP-2) as a bona fide coactivator of ER. However, the molecular mechanism underlying WBP-2 coactivation function was not clear yet. In this study, we explore and identify the mechanism by which WBP-2 acts as coactivator of ER. Our data show that WBP-2 is involved in the regulation of ER target genes, and its expression is required for the proper expression of some ER target genes. To clarify the molecular mechanism by which WBP-2 regulates ER function, we performed chromatin immunoprecipitation assays. We demonstrate here that WBP-2 binds to the ER target gene promoter pS2 promoter and is required for the binding of the phosphorylated form of RNA polymerase II (associated with active transcription/elongation) to the same promoter. Furthermore, we also show that WBP-2 is essential for the recruitment of the histone acetyl transferase p300, an important chromatin modifier enzyme and for histone acetylation at the same target region. Collectively, our data indicate that WBP-2 enhances ER transactivation function at certain genes by facilitating the recruitment and/or the stabilization of a histone modifier enzyme that favors a relaxed chromatin structure, permissive of transcription., (Copyright © 2012 International Union of Biochemistry and Molecular Biology, Inc.)

Abstract

The WW-containing oxidoreductase (WWOX) tumor suppressor participates in a diverse array of cellular activities by virtue of its ability to recognize WW-binding protein 1 (WBP1) and WW-binding protein 2 (WBP2) signaling adaptors among a wide variety of other ligands. Herein, using a multitude of biophysical techniques, we provide evidence that while the WW1 domain of WWOX binds to PPXY motifs within WBP1 and WBP2 in a physiologically relevant manner, the WW2 domain exhibits no affinity toward any of these PPXY motifs. Importantly, our data suggest that while R25/W44 residues located within the binding pocket of a triple-stranded β-fold of WW1 domain are critical for the recognition of PPXY ligands, they are replaced by the chemically distinct E66/Y85 duo at structurally equivalent positions within the WW2 domain, thereby accounting for its failure to bind PPXY ligands. Predictably, not only does the introduction of E66R/Y85W double substitution within the WW2 domain result in gain of function but the resulting engineered domain, hereinafter referred to as WW2_RW, also appears to be a much stronger binding partner of WBP1 and WBP2 than the wild-type WW1 domain. We also show that while the WW1 domain is structurally disordered and folds upon ligand binding, the WW2 domain not only adopts a fully structured conformation but also aids stabilization and ligand binding to WW1 domain. This salient observation implies that the WW2 domain likely serves as a chaperone to augment the physiological function of WW1 domain within WWOX. Collectively, our study lays the groundwork for understanding the molecular basis of a key protein-protein interaction pertinent to human health and disease., (Copyright © 2012 Elsevier Ltd.

Abstract

The YAP2 transcriptional regulator mediates a plethora of cellular functions, including the newly discovered Hippo tumor suppressor pathway, by virtue of its ability to recognize WBP1 and WBP2 signaling adaptors among a wide variety of other ligands. Herein, using isothermal titration calorimery and circular dichroism in combination with molecular modeling and molecular dynamics, we provide evidence that the WW1 and WW2 domains of YAP2 recognize various PPXY motifs within WBP1 and WBP2 in a highly promiscuous and subtle manner. Thus, although both WW domains strictly require the integrity of the consensus PPXY sequence, nonconsensus residues within and flanking this motif are not critical for high-affinity binding, implying that they most likely play a role in stabilizing the polyproline type II helical conformation of the PPXY ligands. Of particular interest is the observation that both WW domains bind to a PPXYXG motif with highest affinity, implicating a preference for a nonbulky and flexible glycine one residue to the C-terminal side of the consensus tyrosine. Importantly, a large set of residues within both WW domains and the PPXY motifs appear to undergo rapid fluctuations on a nanosecond time scale, suggesting that WW-ligand interactions are highly dynamic and that such conformational entropy may be an integral part of the reversible and temporal nature of cellular signaling cascades. Collectively, our study sheds light on the molecular determinants of a key WW-ligand interaction pertinent to cellular functions in health and disease.

3,4,5-Trisubstituted-1,2,4-4H-triazoles (TTs) have recently been identified as a new class of potent non-nucleoside HIV-1 reverse transcriptase (RT) inhibitors. Two series of triazoles have been studied, one of which was also screened against the Y188L mutant. A computational strategy based on molecular docking studies followed by comparative molecular fields analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) has been used to elucidate the atomic details of the RT/TT interactions and to identify the most important features impacting the TT antiretroviral activity. Two 3D-QSAR CoMFA and CoMSIA models were derived, using the TT pEC₅₀ values measured against wild-type (WT) HIV-1 (model A) and the Y188L mutant form (model B), respectively, as the dependent variable. The final model A CoMSIA (r(ncv)²  = 0.97, r(cv)²  = 0.89, SEE = 0.314, and r(pred)²  = 0.82) and model B CoMSIA (r(ncv)²  = 0.91, r(cv)²  = 0.61, SEE = 0.236, and r(pred)²  = 0.73) analyses were more predictive. The results allowed us to obtain useful information for the design of new compounds with improved potency towards WT HIV-1 or that are potentially active against the Y188L mutant.

Abstract

Islet cell autoantigen of 69kDa (ICA69) is a small GTPase-binding protein of unknown function. ICA69 is enriched in the Golgi complex and its N-terminal half contains a BAR domain, a module that can bind/bend membranes and interacts with phospholipids. Here we show that in insulinoma INS-1 cells ICA69 binds to the small GTPase Rab2, which regulates the transport of COPI vesicles between the endoplasmic reticulum and the Golgi complex. Rab2 binds to ICA69 in a GTP-dependent fashion and recruits it to membranes. Over-expression of either Rab2 or ICA69 in INS-1 cells results in a phenotype characterized by: (i) impaired anterograde transport of the secretory granule protein precursors pro-ICA512 and chromogranin A; (ii) reduction of stimulated insulin secretion. Taken together, these data identify ICA69 as a novel Rab2 effector and point to its role in regulating the early transport of insulin secretory granule proteins.

Abstract

Synaptic vesicle trafficking and transmitter release from presynaptic terminals are precisely regulated by a complex array of protein/protein interactions. Several of these proteins are substrates of endogenous protein kinases present in presynaptic terminals. The activity of Ca2+/calmodulin-dependent protein kinase II(CaMKII), one of the kinases involved in the modulation of transmitter release, was previously shown to increase in the hippocampus after long-term blockade of 5-hydroxytryptamine (5-HT) reuptake (a treatment known to elicit an increase in 5-HT release in this area). To investigate the changes induced in presynaptic protein phosphorylation by 5-HT reuptake blockade and concomitant CaMKII up-regulation, we analyzed two major CaMKII presynaptic substrates (synapsin I and synaptotagmin). All 5-HT reuptake blockers that we used, which induce an increase in CaMKII activity and autophosphorylation, also caused a large (2-3-fold) increase in the Ca2+/calmodulin-dependent post hoc phosphorylation of synaptotagmin. Conversely, the phosphorylation of synapsin I is much less affected. The change in synaptotagmin phosphorylation, as determined through immunoprecipitation and quantitative immunoblot analysis after fluvoxamine treatment, is due exclusively to increased phosphate incorporation (presumably caused by the increased kinase activity) and not to a change in the level of substrate protein after the treatment. Thus, drugs known to induce an increase in 5-HT release simultaneously induce an increase in the activity of presynaptic CaMKII and in the phosphate incorporation (post hoc) by a major CaMKII substrate in synaptic vesicles (synaptotagmin). This finding establishes a link between the facilitation of transmitter release induced by antidepressant drugs and the phosphorylation of synaptotagmin by CaMKII.
