TGFB1 and neoplasm: RNA analysis by qPCR with Treg cell marker genes revealed that SRC-3 KO Tregs in spleens of tumor-bearing SRC-3d/d:Treg female mice had elevated expression of anti-inflammatory cytokines such as Tgf-β, Il-10, and Il-35 compared to Tregs from the spleens of tumor-bearing SRC-3f/f female mice (Fig. 4D).
