hsa-mir-221: Hsa-mir-221 is a microRNA implicated in various biological processes and diseases, including cancer [PMC6401030]. It is one of the microRNAs that target genes such as PTEN and DICER1, both of which are involved in oral carcinogenesis [PMC6034275]. In lung cancer, a survival prediction signature includes hsa-mir-221 as a protective factor [PMC4637011]. Elevated levels of hsa-mir-221 have been observed in endometrial carcinoma (EC) when compared to the normal endometrium (VP) [PMC4165582]. In ovarian cancer, statistical significance improved when analyzing hsa-mir-221 in combination with hsa-miR-1285 [PMC4278335]. Hsa-mir-221 is also highly associated with kidney renal clear cell carcinoma (KIRC) along with other miRNAs and long non-coding RNAs (lncRNAs) [PMC6251074]. Its abnormal expression is linked to the development of malignant tumors, including its counterpart hsa-miR-222 [PMC9917093]. Furthermore, hub target genes such as FOS and ESR1 have been identified for hsa-mir-221 through the analysis of miRNA-target gene relationships [PMC6171011].
