In addition, correlation analysis in TCGA ESCC, GSE21293, and Liu2021 showed that both mRNA and protein levels of TRIM29 positively correlated with CDH1 (E-cadherin), while negatively correlated with CDH2 (N-cadherin), VIM (vimentin), SNAI1 (Snail), MMP2 and MMP9 (Fig. 6D–I; SNAI1 was not available in Liu2021 dataset). Here, MMP2 is linked to esophageal squamous cell carcinoma.
