Correlation of PRKCB mRNA expression and DNA methylation levels in gastric cancer from GWAS Catalog. (a) The mRNA expression level of PRKCB was decreased in gastric cancer tissues compared with adjacent normal tissues (P = 0.077). The p-value was calculated by the two-sided paired Student’s t-test. (b) PRKCB DNA methylation states at four distinct locations of the gastric cancer. (c) Scatter plots showing a correlation between the DNA methylation and expression of PRKCB.
