Abstract:
MircoRNA (miRNA) are a group of small, non-coding, regulatory RNA with an average length of approximately 22 nucleotides, which mostly modulate gene expression post-transcriptionally through complementary binding to the 3'-untranslated region (3'-UTR) of multiple target genes. Emerging evidence has shown that miRNA are frequently dysregulated in a variety of human malignancies. Among them, microRNA-145 (miR-145) has been increasingly identified as a critical suppressor of carcinogenesis and therapeutic resistance. Resistance to tumor therapy is a challenge in cancer treatment due to the daunting range of resistance mechanisms. We reviewed the status quo of recent advancements in the knowledge of the functional role of miR-145 in therapeutic resistance and the tumor microenvironment. It may serve as an innovative biomarker for therapeutic response and cancer prognosis.
