Abstract:

Colorectal cancer stem cells(CCSCs) are a subpopulation of colorectal cancer cells with the potential of self-renewal, proliferation and differentiation, which can initiate and promote the occurrence and progress of colorectal cancer. And it is closely related to the recurrence, metastasis, radiotherapy and chemotherapy resistance of colorectal cancer. MicroRNAs are a kind of small noncoding RNAs, involved in post-transcriptional regulation. A large number of studies have shown that MicroRNAs play an important role in the self-renewal, proliferation, differentiation, drug resistance and other biological processes of colorectal cancer stem cells. Herein we summarized various mechanisms of MicroRNAs regulating the characteristics of colorectal cancer stem cells, especially in a variety of signal pathways. In addition, we introduced the application prospect of MicroRNAs in the diagnosis and treatment of colorectal cancer. Advanced study of the molecular mechanism of MicroRNAs in colorectal cancer stem cells will help us to understand the biological characteristics and behavior of colorectal cancer stem cells better, and will also provide a new reference for clinical treatment of targeted colorectal cancer stem cells.

Key words: Colorectal neoplasms, MicroRNAs, Cancer stem cells
