hsa-mir-1246: Hsa-mir-1246 is a microRNA that was identified in a study analyzing serum exosomal miRNA expression profiles [1]. The study found that hsa-mir-1246, along with hsa-miR-1290 and hsa-miR-29c-3p, exhibited the same regulation direction in both tumor tissues and sera [1]. Another study investigated the effects of hsa-mir-1246 inhibition in the Caco-2 and HCT116 cell lines [2]. The results showed that complete coverage of the gap area was achieved 72 hours after cell transfection with both miR-Control and hsa-mir-1246 inhibitor in Caco-2 cells, and 96 hours after transfection with miR-Control and hsa-mir-1246 inhibitor in HCT116 cells [3]. Additionally, a feature selection method identified hsa-mir-1246 as one of the 50 most informative attributes [4]. These findings suggest that hsa-mir1246 may play a role in tumor regulation and could be used as a potential biomarker [1]. Further research is needed to fully understand its function and potential clinical applications [1].
