MicroRNAs involved in drug resistance of breast cancer by regulating autophagy.

MicroRNAs involved in drug resistance of breast cancer by regulating autophagy. J Zhejiang Univ Sci B. 2020 Sept.;21(9):690-702 Authors: Wen N, Lv Q, Du ZG Abstract Autophagy is a conserved catabolic process characterized by degradation and recycling of cytosolic components or organelles through a lysosome-dependent pathway. It has a complex and close relationship to drug resistance in breast cancer. MicroRNAs (miRNAs) are small noncoding molecules that can influence numerous cellular processes including autophagy, through the posttranscriptional regulation of gene expression. Autophagy is regulated by many proteins and pathways, some of which in turn have been found to be regulated by miRNAs. These miRNAs may affect the drug resistance of breast cancer. Drug resistance is the main cause of distant recurrence, metastasis and death in breast cancer patients. In this review, we summarize the causative relationship between autophagy and drug resistance of breast cancer. The roles of autophagy-related proteins and pathways and their associated miRNAs in drug resistance of breast cancer are also discussed. PMID: 32893526 [PubMed - in process]
