This study revealed that both dietary stilbenoids (resveratrol and piceatannol), alone or in combination, increased the PD-L1 expression in Cal51 triple-negative breast cancer (TNBC) and SW620 colorectal cancer cells via histone deacetylase HDAC3/p300-mediated nuclear factor (NF)-κB signaling [42]. Here, CD274 is linked to colorectal cancer.
