Rice hull polysaccharides (RHPS) have been reported to activate innate immunity in mice. This study investigated the effects of RHPS on natural killer (NK) cell-mediated cytotoxicity in vitro and the possible underlying anticancer mechanisms in vivo. The results showed that sustained exposure to RHPS increased NK-92MI cell-mediated cytotoxicity in a time- and concentration-dependent manner. In addition, RHPS upregulated the expression of Fas ligand, TNF-related apoptosis-inducing ligand, perforin, and granzyme B of NK-92MI cells and induced the secretion of IFN-γ and TNF-α. In the in vivo experiment, colon cancer CT26-bearing mice were used to investigate the effects of RHPS in cytotoxicity and anti... More
