Mir-221 microRNA

In molecular biology, mir-221 microRNA (and its paralogue, mir-222) is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.

mir-221 is an oncogenic microRNA.[1] It targets CD117, which then prevents cell migration and proliferation in endothelial cells.[2][3] miR-221 is known as an anti angiogenic miRNA.[4][2] Recent important studies have reported that miR-221 is also involved in induction of angiogenesis.[5][6][7] RNA induced Silencing Complex (RISC) proteins SND1 and AEG-1 induces miR-221 expression in Liver cancer.[8] In liver cancer miR-221 induces the tumor angiogenesis.[5] miR-221 detection in human faeces can be a non-invasive screening marker for colorectal cancer.[9]

miR-221 has been identified as playing a role in androgenetic alopecia.[10]
