Dickkopf-1 (DKK1) can contribute to immune evasion through modulation of natural killer (NK) cell activity. (A) CIBERSORT2 immune cell composition analysis of the Stand Up to Cancer/Prostate Cancer Foundation metastatic castration-resistant prostate cancer cohort (n = 212) was carried out. DKK1 low and high groupings represent the bottom and top quartiles of DKK1 mRNA expression. (B) and (C) Mean tumor volumes and SEM are plotted. P values from two-way repeated-measures analysis of variance with Sidak’s multiple comparisons. Representative data from one of two independent experiments are shown. SCID, severe combined immunodeficient.
