Background
miR-125a-5p regulated biological processes in various types of cancer, including colorectal cancer (CRC). TAZ, a vital transcriptional coactivators of the Hippo pathway, was found to be overexpressed in various cancers. Objectives: This study aims to study the effect of miR-125a-5p on the progression of CRC by regulating TAZ expression.
Conclusion
Our data suggest that miR-125a-5p inhibits CRC cell migration, invasion and EMT by targeting TAZ. These results suggest that miR-125a-5p serves as a potential therapeutic biomarker for CRC patients.
Methods
In this study, miR-125a-5p and TAZ expression in CRC tissue and cell lines were detected by real-time polymerase chain reaction (RT-PCR). Luciferase reporter assay was applied to detect whether TAZ was a target of miR-125a-5p. Cell migration and invasion were detected in vitro by wound-healing assay and cell invasion assay. Western blot was used to detect the expression of epithelial-mesenchymal transition (EMT)-related proteins. Findings: The
