AR and neoplasm: Although no statistically significant difference was observed between groups of tumor-bearing mice, serum from mice treated with Ad-Control and anti-PD1 or Ad-AR-V7 and anti-PD1 had significantly higher anti-mCherry IgG than tumor-naïve mice, demonstrating the induction of tumor-cell-specific adaptive immunity against these lines that was protected by AR-V7 expression (Figure S8).
