Research progress of MicroRNAs involved in the tumor microenvironment regulation in non-cell-autonomous mechanisms / 天津医药

ABSTRACT

As an internal environment of tumor occurrence, tumor microenvironment is composed of a variety of cells and extracellular matrix, and plays a crucial role in tumor formation, transfer and resistance to drugs. The regulation of tumor microenvironment will be a potential target to control the cancer. MicroRNAs (miRNAs) are a kind of 21 to 25 nucleotides single-stranded RNA, and are mainly involved in regulating gene expression. Recently, with the suggestion of cellular auton-omous tumor inhibition mechanism, the regulation of tumor microenvironment by miRNAs has received great attention. This review summarizes recent findings on the non-cell-autonomous mechanisms of miRNAs-mediated regulation of tumor micro-environments, which provides foundations and perspective on the design of therapeutic interventions.
