Function of miRNA-145-5p in the pathogenesis of human disorders.

miR-145-5p is a microRNA whose role in diverse disorders has been verified. This miRNA is encoded by MIR145 gene on chromosome 5. This miRNA is mainly considered as a tumor suppressor miRNA in diverse types of cancers, including bladder cancer, breast cancer, cervical cancer, cholangiocarcinoma, renal cancer, and gastrointestinal cancers. However, few studies have reported up-regulation of this miRNA in some cancers. Moreover, it has been shown to affect pathogenesis of a number of non-malignant conditions such as aplastic anemia, asthma, cerebral ischemia/reperfusion injury, diabetic nephropathy, rheumatoid arthritis and Sjögren syndrome. In the current review, we summarize the available literature about the role of miR-145-5p in these conditions.
