Fig. 4From: Discovery of natural products capable of inducing porcine host defense peptide gene expression using cell-based high throughput screeningInduction of multiple porcine HDP expression in IPEC-J2 cells by xanthohumol, isorhapontigenin, deoxyshikonin, and calycosin in porcine intestinal explants. Porcine jejunal explants were treated with or without indicated concentrations of each compound for 24 h, followed by RT-qPCR analysis of pBD3, pBD2, PG1-5, and pEP2C. The results are the mean ± SEM of three independent experiments. *P < 0.05 vs. non-treated control by unpaired Student’s t-testBack to article page
