This adenosine analog is now commonplace in natural product small molecule chemical screening libraries, and as such has been discovered as active in mammalian disease pathways that include Parkinson’s disease, Huntington’s disease (HD) and Familial Dysautonomia. We provide a perspective on our data relative to HD and recent discoveries of genetic modifiers of this disease predominantly related to DNA damage repair. We outline the importance of nucleotide salvage and the presence of this adenosine analog in human samples and efficacy in models of human disease, with mechanisms that are empowered by chemical studies using N6FFA as a nucleic acid crosslinking agent.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"54 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89333022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"NOXA the BCL-2 Family Member behind the Scenes in Cancer Treatment","authors":"Alison Dumont, Steven Lohard, L. Maillet, P. Juin, S. Barillé-Nion","doi":"10.33696/signaling.1.021","DOIUrl":"https://doi.org/10.33696/signaling.1.021","url":null,"abstract":"Apoptosis, a programmed cell death relying on the cascade activation of caspases, regulates many processes ranging from embryonic development to immune homeostasis, and plays a major role in cancer. Escape from apoptosis is indeed one of the fundamental characteristics of tumor cells that frequently exhibit increased expression of the main prosurvival BCL-2 homologues BCL-2, BCL-xL and/ or MCL-1 contributing to tumor progression or resistance to anticancer treatments [1]. Mitochondria Outer Membrane Permeabilization (MOMP) is a key cellular event in apoptosis as subsequent release of cytochrome-c (cyto-c) from the mitochondrial intermembrane space to cytosol through BAX/BAK pores, promotes apoptosome formation and downstream activation of apoptotic effector caspases. MOMP can also lead to the release of other mitochondrial components including mitochondrial DNA that engage additional inflammatory signalling pathways inhibited by apoptotic caspases [2,3]. BCL-2 family proteins tightly control BAX/BAK-dependent MOM permeability through a dynamic network of protein-protein interactions integrating various cellular stresses and finally dictating life or death decisions and cell fates [4]. Chemotherapies often upregulate expression of proapoptotic BCL-2 homologues in cancer cells, shifting by this way the balanced death/survival signals towards apoptosis as an expected cytotoxic effect. Among the proapoptotic BH3only proteins of the BCL-2 family, NOXA is unique since in preferentially inhibiting the prosurvival BCL-2 homologue MCL-1, it decreases the protective effect MCL-1 exerts on mitochondrial membranes and transfers MOM integrity surveillance and downstream prevention of caspase activation, mostly to BCL-2 and/or BCL-xL. This was observed in particular during mitotic-related stress after antimitotic treatment or during endoplasmic reticulum (ER) stress induced by proteasome inhibitors, where NOXA was shown to accumulate through transcriptional or post-translational mechanisms, as we detail in this review. Importantly, prosurvival members of BCL-2 family are Abstract","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79196870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Desmosomes occur in abundance in tissues, such as the skin and mucous membrane that are subjected to extensive mechanical stress. In addition to its role in cell-cell adhesion, Dsg3 also functions as a surface regulator for various intracellular signaling pathways in epithelial cells [1-7]. Many of these findings are achieved from the studies of the pathogenesis of Pemphigus Vulgaris (PV), an autoimmune bullous disease in which Dsg3 serves as a major autoantigen and is targeted by circulating autoantibodies that cause disruption of desmosomes, resulting in blistering affecting both the skin and mucous membrane [2,3,6]. This minireview will focus on our recent findings suggesting an unprecedented signaling role of Dsg3 in regulating two fundamental pathways that control cell proliferation and cell fate decision [8,9]. The involvement of this pathway in the pathogenesis of PV is also discussed briefly in this review.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76756943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reverter","doi":"10.33696/signaling.1.023","DOIUrl":"https://doi.org/10.33696/signaling.1.023","url":null,"abstract":"151 Protein ubiquitination is a major post-translational mechanism that regulates fate and function of many proteins in the cell, either by regulating their abundance by the 26S-proteasome-ubiquitin system or by modulating protein activity by the attachment of the ubiquitin modifier [1]. Thus, in addition to targeting proteins for proteasomal degradation, ubiquitin plays a role in many other non-degradative processes in the cell, including transcription, cell cycle, DNA repair, apoptosis, immune response, endosomal sorting, among others [2]. Protein ubiquitination requires the coordination of an enzymatic cascade composed by the E1 activation enzyme, E2 conjugating enzyme, and the E3 ligase. Sometimes, E2 can directly guide ubiquitin to bind to the substrate, but in most circumstances, the cooperative work of E3 ligase is required for catalysis and specificity [3]. Deubiquitinating enzymes (DUBs) can reverse ubiquitination by removing ubiquitin from protein targets having an opposite function to the E3 ligases. Coordination of these two activities contributes to the fine-tune regulation of target ubiquitination inside the cell, and in some cases their abundance or half-life when ubiquitin targets protein degradation by the proteasome. Deregulation of DUBs activity can be linked to several diseases, such as cancer or neurodegeneration among others, indicating the major role of this proteolytic activity for a correct cellular homeostasis.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81493501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More specifically, vomiting is the act of forceful expulsion of gastrointestinal contents through the mouth, whereas nausea is an unpleasant painless subjective feeling that one will imminently vomit.

The act of vomiting is usually preceded by retching, where the gastrointestinal tract contents are forced into the esophagus, without the vomitus being expelled [1]. While significant knowledge exists on the neurotransmitter and anatomical basis of vomiting [2-4], nausea is the neglected symptom and its anatomical neurochemistry remains to be fully defined.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"1 4","pages":"155-159"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7793561/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39140582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current interventions against obesity and/or type 2 diabetes such as calorie restriction, exercise, genetic manipulations or established pharmacological treatments have not been successful for many patients with obesity and/or type 2 diabetes. There is an urgent need for new strategies to treat insulin resistance, T2D and obesity. Increased activity of stress-responsive pathways has been linked to the pathogenesis of insulin resistance in obesity. In this commentary, we argue that chronic upregulation of MKP-1 in skeletal muscle is part of a stress response that contributes to the development of insulin resistance, T2D and obesity. Therefore, inhibition of MKP-1 in skeletal muscle is a potential strategy for the treatment of T2D and obesity. We highlight therapeutic strategies for potential targeting of MKP-1 in skeletal muscle for the treatment of metabolic diseases as well as other diseases of skeletal muscle.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"111 1","pages":"160 - 168"},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73979953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although most cases of MS are considered obese and insulin-resistant, they are characterized by inflammatory cytokine activity and chronic low-grade inflammation. Also, assumptions about the role of MS and organ interaction during target organ damage become increasingly important. Method: For this study, online research and screening were carried out in electronic databases such as PubMed, Web of Science, and Google Scholar; using the terms “metabolic syndrome” and “organ crosstalk” as keywords. Results: Due to the unpredictable clinical course and treatment uncertainty in this multi-factor chronic disease, increased organ interaction and complications lead to an increase of biomarkers in blood circulation, each of which has diagnostic potential. Therefore, a better understanding of inflammatory triggers and organ interferences will also help determine therapeutic targets and prevent organ damage associated with metabolic syndrome. Conclusion: This mini review presents an overview of the relationship between MS and organ crosstalk. More research is needed to fully elucidate the relationship between MS and organ crosstalk, the pathological conditions it causes, and biomarkers related to MS.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81685772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
