MMP9 and urinary bladder cancer: Correlation analysis in bladder cancer samples from TCGA BLCA demonstrated a positive correlation between mRNA levels of IGF2BP3 and SNAI1 (Snail), SNAI2 (Slug), CDH2 (N-cadherin), VIM (vimentin), and MMP9 (Fig. 6E–I), further supporting the association between IGF2BP3 and EMT-related markers.
