CXCL8 and posterior cortical atrophy: Under obese conditions, increased CXC chemokine ligand 1 (CXCL1) expression is associated with PCa aggressiveness (63); elevated CXC chemokine ligand 8 (CXCL8) and CXC chemokine ligand 12 (CXCL12) expression are positively correlated with PCa metastasis (64–66).
