hsa-miR-5091: Hsa-mir-5091 is a microRNA that has been identified in various studies as a potential biomarker for different types of cancer, including colorectal cancer (CRC), pancreatic ductal adenocarcinoma, and glioma [PMC6863365] [PMC7362410] [PMC7393356]. However, the specific role and mechanism of hsa-mir-5091 in tumors, particularly in CRC, have not been fully elucidated and require further investigation [PMC6863365]. In CRC prognostic prediction models, hsa-mir-5091 has been included as one of the molecules used for risk score calculation and survival prediction [PMC8176021]. Additionally, hsa-mir-5091 has been found to have overlapping target genes with other miRNAs in different cancer types [PMC6863365]. In the context of a prognostic signature for CRC, hsa-mir-5091 is one of the miRNAs used to construct the risk score formula [PMC6089101]. Overall, hsa-mir-5091 shows potential as a biomarker for cancer prognosis and risk prediction. However, further research is needed to fully understand its functional role and mechanism in different types of tumors.
