Moreover, there was a positive correlation between P4HA1 expression and the expression of four methyltransferases (DNMT1, DNMT2, DNMT3A, and DNMT3B) in many tumor types, including ACC, CESC, chromophobe RCC, papillary RCC, LGG, PRAD, READ, SKCM, TGCT, THCA, UCEC, and UVM. The gene discussed is P4HA1; the disease is adrenal cortex carcinoma.
