MMP9 and colorectal carcinoma: The protein level of E-cadherin was reduced in DLD1-UBQLN1 cells compared with the control level (Figure 2N), and the protein level of VIMENTIN and MMP-9 was reduced in LoVo-shUBQLN1 cells compared with the control level (Figure 2O), suggesting that UBQLN1 may also enhance CRC cells’ EMT.
