Differences in splicing factors may predict type 2 diabetes remission in the CORDIOPREV study

Le résumé fourni par la source

Alternative splicing is a post-transcriptional process resulting in multiple protein isoforms from a single gene. Abnormal splicing may lead to metabolic diseases, including type 2 diabetes mellitus (T2DM). To identify the splicing factor expression that predicts T2DM remission in coronary heart disease (CHD) patients, we identified newly diagnosed T2DM at baseline ( n = 190) from the CORDIOPREV study. Patients were classified as Responders (T2DM remission during 5 years without antidiabetic drugs) or non-Responders. Baseline dysregulation in 5 splicing factors ( MBNL1 , RBM5 , hnRNP G/RBMX , CD44 , NT5E ) distinguished Responders from non-Responders. Adding these factors to clinical variables [AUC = 0.67], insulin resistance, and beta-cell indexes [AUC = 0.76], improved T2DM remission prediction [AUC = 0.80]. Cox regression analysis showed those with higher remission scores had a 2.63-fold increased remission probability. To conclude, a set of splicing factors that contribute to predicting T2DM remission in patients with CHD has been identified. Further research is needed to elucidate these findings' clinical relevance.
