【 摘 要 】

Colorectal cancer (CRC) is a major worldwide health problem due to its high prevalence and mortality rate. microRNA has been reported playing an important role in a variety of cancers including colorectal cancer. miR-203a-3p has been found up-regulated in CRC tissues compare with the adjacent normal tissues. But, how miR-203a-3p regulates CRC development remains to be elucidated. In this study, gain and loss-of-function assays showed that miR-203a-3p promotes colorectal cancer cell proliferation, colony formation and migration and invasion by targeting PDE4D. And miR-203a-3p/β-catenin/Cyclin D1/c-Myc signaling pathway is involved in the CRC. In summary, this study highlights an onco-miRNA role for miR-203a-3p by regulating PDE4D in CRC and suggests that miR-203a-3p may be a novel molecular therapeutic target for CRC.
