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}

Here, we identified insulin receptor substrate 2 (IRS-2), a cytoplasmic adaptor protein, as a novel transcriptional target of ASPSCR1::TFE3. Ectopic expression of ASPSCR1::TFE3 led to increased IRS-2 mRNA and protein levels. Chromatin immunoprecipitation and luciferase assays demonstrated that ASPSCR1::TFE3 bound to the <em>IRS-2</em> promoter region and enhanced its transcription. Moreover, IRS-2 was highly expressed in the ASPSCR1::TFE3-positive RCC cell line FU-UR1, while small interfering RNA-mediated depletion of ASPSCR1::TFE3 markedly decreased IRS-2 mRNA and protein levels. Functionally, IRS-2 knockdown attenuated activation of the PI3K/AKT pathway and reduced proliferation, migration, invasion, adhesion, and clonogenicity in FU-UR1 cells. Pharmacological inhibition of IRS-2 also reduced AKT activation as well as cell viability, clonogenicity, migration, invasion, and adhesion.

Recently, DNA damage has been connected with the pathogenesis of heart failure. Cell adhesion associated, oncogene regulated (CDON), considered as an N-linked glycoprotein, is a transmembrane receptor for modulating cardiac function. But the role of CDON and its glycosylation in DNA damage remains unknown. In this study, we found that the knockdown of CDON caused DNA double-strand breaks as indicated by an increase in phosphorylated histone H2AX (γH2AX) protein level, immunofluorescent intensity of γH2AX and tail DNA moment in H9c2 cardiomyocytes. Conversely, overexpression of CDON led to decreasing DNA damage induced by hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) and upregulating the expression of genes related to DNA repair pathways-homologous recombination (HR) and non-homologous end joining (NHEJ). Moreover, we expressed nine predicted N-glycosylation site mutants in H9c2 cells prior to treatment with H<sub>2</sub>O<sub>2</sub>. The results showed that mutation of N-glycosylation sites (N99Q, N179Q, and N870Q) increased the accumulation of DNA damage and downregulated the expression of HR-related genes, demonstrating that CDON N-glycosylation on DNA damage is site-specific and these specific N-glycan sites may regulate HR repair-related transcript abundance of genes.
