Effects of genistein on mRNA expression levels of inflammation-related genes (TNF, IL1B, CXCL8, CXCR2, HPSE, IL10, and PPARG) in (A) HT29 cells and (B) SW620 cells determined by real-time PCR. The measurements were made with genistein 100 μM or 0.1% DMSO (control cells) treatment for 48 h. Values are expressed as mean ± SEM and control values (DMSO-treated cells) were set at 1.00. The coordinate values represent mRNA levels (arbitrary units). GEN, genistein; A.u., arbitrary units. * Significant difference between control cells and genistein-treated cells (Student’s t-test; p < 0.05, n = 6).
