Association of miR-200a and miR-205 Expression with Epithelial-Mesenchymal Transition in Colorectal Cancer Cells

MicroRNAs play acritical role in EMT regulation through tightly regulating the transcription factors. EMT (Epithelial-Mesenchymal Transition) in the colorectal cancer cell (CRC) is a highly controlled mechanism, contributing to the development of progressive cancer. Throughout this research, miR-200a/205 was focused as a component implicated throughout regulating the EMT process in colorectal cancer cells. In this sense, the induction of the EMT process was made using colorectal cancer cell lines.

The mRNA levels of E-cadherin, Vimentin, β-catenin, Zeb1, and Snail were determined using real time-PCR for characterization of the EMT process. True real time-PCR was conducted for evaluating the alteration amount of microRNAs.

The findings of this study verified the in-vitro EMT model being developed. The in vitro analysis revealed a negative correlation between the Zeb1 and Snail miR-200a and miR205 (P=0.001) (P=0.0001). The results of miR-200a and miR205 are regulated down in vitro.

miR-200a and miR205 may be used as candidates in further research to prevent colorectal cancer's invasive properties via the EMT process
