To explore the effect of CCL2 and CXCL8 cytokines on PCa cells growth, LNCaP and CWR‐R1 cell lines were cultured in FCS‐proficient medium with addition of 1 pg·mL−1 of CCL2 or CXCL8, but only a marginal effect in reducing CWR‐R1 cell growth was seen (Fig. S4). Here, CXCL8 is linked to posterior cortical atrophy.
