By data mining the PCa samples from TCGA cohort, we found that PRKAR2B expression was closely correlated with the expression of these glycolytic components in prostate cancer (Figure 3J) and this correlation was absent in the non‐tumour samples obtained from the Genotype‐Tissue Expression (GTEx) database (Figure S2). The gene discussed is PRKAR2B; the disease is Familial prostate cancer.
