Regarding chemokines and their receptors (Figures 6B, C), PLAG1 is significantly positively correlated with chemokines such as CXCL9, CXCL10, and CCL5, as well as their receptors (including CCR5, CXCR3, and CXCR4) in PRAD and BRCA. The gene discussed is CXCL10; the disease is prostate adenocarcinoma.
