Pearson correlation analysis using the TIDE web tool showed that increased CHST12 expression was associated with an increase in the number of cytotoxic T lymphocytes in two PAAD datasets (TCGA-PAAD and GSE21501@PRECOG, TCGA-PAAD; r = 0.185, p = 0.0147; GSE21501, r = 0.306, p = 0.00178) (Figures 5A, B). Here, CHST12 is linked to pancreatic adenocarcinoma.
