Figure 3. Prognostic significance of GPR27 methylation in gastric cancer. The heat map unveils that high expression of GPR27 corresponds to low DNA methylation in gastric cancer (A). A strong correlation between GPR27 expression and DNA methylation is noticed in gastric cancer (B). Hypermethylation of GPR27 is correlated with relatively superior overall survival (C) and disease-free survival (D) in sufferers with gastric cancer.
