PTP4A1 and colorectal carcinoma: Moreover, the overexpression of miR-26b was reported to target four different oncogenes: TATA-box binding protein associated factor 12 (TAF12), protein tyrosine phosphatase type IVA, member 1 (PTP4A1), checkpoint with forkhead and ring finger domains (CHFR), and STE20-related kinase adaptor beta (ALS2CR2), to suppress the cell growth and the induction of apoptosis associated with the invasiveness and metastasis of CRC cells.
