Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?

MIR490 is a microRNA (miRNA) that has been identified as a potential tumor suppressor in various cancers, including bladder, lung, and ovarian cancers [PMC7287171]. It is known to target and suppress the expression of genes such as FOS, HMGA2, CCND1, and CDK1 that are involved in cell proliferation and the cell cycle [PMC7287171]. MIR490 is one of the miRNAs that are methylated in certain cell lines but not in control B cells [PMC5485978]. It has been found to target fewer than 200 genes, which is a relatively small number compared to other miRNAs such as MIR24-2 and MIR142 [PMC7287171]. In extracellular vesicles (EVs) derived from human periodontal ligament stem cells (hPDLSCs), MIR490 is one of five representative miRNAs present [PMC8308278], which suggests its role in intercellular communication. The expression of MIR490 can be regulated by CCAT1 in gastric cancer and has been shown to be negatively correlated with CCAT1 expression; high levels of MIR490 can significantly restrain gastric cancer metastasis [PMC9844612]. In lung cancer specifically, lower expression levels of MIR490 have been associated with poor survival outcomes [PMC7212445]'>PMC7212445], indicating its potential as a prognostic biomarker. Additionally, aberrant expression patterns involving MALAT1 may act as competing endogenous RNA (ceRNA), inhibiting MIR490 and leading to tumor progression through increased HMGA2 expression [PMC7212445].
