Recent reports suggest combination therapy as a potential strategy to combat the complex pathogenesis of such neurodegenerative disorders. The present study attempted to identify a combinatorial intervention strategy against human poly(Q) disorders in <em>Drosophila</em> disease models. Due to its immense potential to be stimulated by drugs, the evolutionarily conserved insulin signalling cascade which is well-established modifier of human poly(Q) pathogenesis was selected for the study. Genetic screening studies identified <em>Drosophila</em> Myc as a potential partner of insulin receptor (InR) that conferred additive rescue against poly(Q) induced neurodegeneration. Comprehensive analyses demonstrated InR and Myc to confer additive rescue against several events of pathogenesis, including aggregation of expanded poly(Q) containing proteins, transcriptional dysregulation, upsurge of cell death cascades, etc. Also, the synergistic rescue efficiency of InR and Myc was equally efficient in mitigating poly(Q) induced structural and functional deficits. The study also demonstrates that Myc functions downstream of InR signalling cascade to deliver rescue against human poly(Q) mediated toxicity in <em>Drosophila</em> disease models. In conclusion, the present study suggests that InR and Myc have the potential to be developed as a combinatorial therapeutic approach against human poly(Q) diseases.</div></div>","PeriodicalId":50335,"journal":{"name":"International Journal of Biochemistry & Cell Biology","volume":"177 ","pages":"Article 106690"},"PeriodicalIF":3.4,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142630995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PARKIN, E3 ubiquitin ligase, plays a crucial role in maintaining mitochondrial quality control, albeit the role of other E3 ligases in regulating mitochondrial functions is not understood. In the current study, we explored the implication of TRIM71, E3 ubiquitin ligase, in the modulation of mitochondrial functions and neuronal death in PD stress conditions induced by rotenone and 6-OHDA. Ectopic expression of TRIM71 in SH-SY5Y dopaminergic neuronal cells sensitizes to PD stress-induced cell death, while its knock-down rescues neuronal cell death. TRIM71 turnover is enhanced in neurons under PD stress conditions. TRIM71 predominantly localizes on the outer mitochondrial membrane and translocation increases during PD stress conditions. TRIM71 regulates mitochondrial complex I and IV assembly and activity. TRIM71 knock-down decreases mitochondrial ROS and enhances ATP level as well as mitochondrial membrane potential in PD stress conditions. TRIM71-mediated mitochondrial ROS and cell death were rescued by mitoTEMPO, a mitochondrial-targeted antioxidant. Altogether, the evidence strongly suggests TRIM71-mediated modulation of mitochondrial functions and neuronal apoptosis in PD stress conditions.</div></div>","PeriodicalId":50335,"journal":{"name":"International Journal of Biochemistry & Cell Biology","volume":"177 ","pages":"Article 106689"},"PeriodicalIF":3.4,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142630907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth of triple-negative breast cancer (TNBC) cells is glucose-dependent. The integrated stress response (ISR) is a cellular stress response to glucose depletion. The ISR-solute carrier family 7 member 11 pathway is activated during glucose depletion and contributes to glucose dependence by decreasing intracellular glutamate levels. Solute carrier family 1 member 5 (SLC1A5) and the mitochondrial solute carrier family 1 member 5 variant (SLC1A5var) are glutamine transporters that play essential roles in the reprogramming of cancer metabolism. However, whether ISR can regulate mitochondrial SLC1A5var expression and further affect glucose dependence remains unclear. Glucose depletion-, oligomycin-, and salubrinal-activated activating transcription factor-4 (ATF4) induced SLC1A5var expression. ATF4 is critical for SLC1A5var regulation, as it binds to specific regulatory elements in its promoter. SLC1A5var knockdown decreases glucose depletion-induced cell death, whereas SLC1A5var overexpression increases glucose depletion-induced cell death in TNBC cells. SLC1A5var knockdown reduced cancer cell proliferation, colony formation, and migration, whereas SLC1A5var overexpression increased cell proliferation and migration. Moreover, the knockdown of SLC1A5var reduces the oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) while increasing the maximal OCR and ECAR under glucose depletion. These results suggest that activated ISR-induced increased expression of SLC1A5var may regulate mitochondrial oxidative phosphorylation and glycolytic metabolic characteristics to enhance glucose depletion-induced cell death. In conclusion, SLC1A5var plays a vital role in metabolic reprogramming and may be a potential target for breast cancer treatment.</div></div>","PeriodicalId":50335,"journal":{"name":"International Journal of Biochemistry & Cell Biology","volume":"177 ","pages":"Article 106688"},"PeriodicalIF":3.4,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
