MMUT and colorectal carcinoma: We found that the luciferase activity of pmirGLO‐TP53INP1‐3' UTR was reduced dramatically after treatment with miR‐548n mimics, but did not change in CRC cells transfected with pmirGLO‐TP53INP1‐MUT‐3'UTR (Figure 4B), this results indicated that miR‐548n could bind to the TP53INP1 3'‐UTR directly.
