hsa-mir-561: Hsa-mir-561 is a microRNA that has been identified in various studies to be associated with different types of cancers, including prostate cancer (PCa) [PMC8426106], colon cancer (COAD) [PMC6937800], papillary renal cell carcinoma [PMC6937800], hepatocellular carcinoma (HCC) [PMC7723630], and mammary gland cancer in goats and cattle [PMC4608672]. In PCa, hsa-mir-561 is one of the 22 upregulated differentially expressed microRNAs that can predict gene expression regulation [PMC8426106]. In COAD, hsa-mir-561 is one of the seven microRNAs with a positive coefficient, indicating its driving effect on COAD development and progression [PMC6937800]. In papillary renal cell carcinoma, hsa-mir-561 has been identified as a prognostic biomarker [PMC6937800]. In HCC, hsa-mir-561 is one of the three miRNAs that may serve as possible prognostic predictors for the disease [PMC7723630]. Furthermore, hsa-mir-561 has been found to be upregulated in hepatocellular carcinoma tissues compared to normal tissues [PMC6889128]. The function of the mir-561 family in mammary gland cancer is not yet known but its seed region suggests its association with this family in goats and cattle. The expression levels of hsa-mir-561 have also been found to be altered in various other cancers such as colon cancer and HCC.
