The expression levels of four inflammation-related genes (TRPV1, iNOS, IL-1β, and IL-8) were decreased significantly (p < 0.05) in the human colorectal adenocarcinoma Caco-2 cells treated with three different concentrations (12.5, 25, and 50 mg/L) of PS-MPs for 24 and 48 h [30]. This evidence concerns the gene CXCL8 and colorectal adenocarcinoma.
