The authors investigated the transcriptional expressions, methylation level and prognostic value of S100As in pancreatic ductal adenocarcinoma (PDAC) patients from the Oncomine, GEPIA2, Linkedomics and cBioPortal databases. Real-time PCR was used to detect the expressions of S100A2/4/6/10/14/16 in four pancreatic cancer cell lines and pancreatic cancer tissues from PDAC patients undergoing surgery.

Scientists experimentally verified one such micropeptide encoded by a β cell- and neural cell-enriched lncRNA TCL1 upstream neural differentiation-associated RNA. They provided the first evidence that lncRNA-encoded micropeptides played a critical role in pancreatic β cell functions and provided a foundation for future comprehensive analyses of micropeptide function and pathophysiological impact on diabetes.
