Integration of transcriptomics and metabolomics data revealed role of insulin resistant SNW1 gene in the pathophysiology of gestational diabetes
Published 2025-02-01“…Metabolomic studies indicated significantly elevated gluconeogenesis in GDM, evidenced by decreased levels of alanine and increased levels of pyruvate and glucose compared to controls. siRNA-mediated knockdown of SNW1 in PANC1 cells resulted in significant down-regulation of alanine aminotransferase (ALT/GPT) and insulin receptor substrate (IRS1), while glucose transporters (GLUT2/GLUT4) and insulin (INS) were significantly up-regulated at both mRNA and protein levels. This study identified SNW1 as a novel insulin-resistant gene that induces hyperglycemia by elevating gluconeogenesis and decreasing glucose uptake. …”
