Fig. 5From: Sijunzi Decoction attenuates 2, 4, 6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats and ameliorates TNBS-induced claudin-2 damage via NF-κB pathway in Caco2 cellsExpression of tight junction proteins in Caco2 cells monolayers. Total RNA was isolated from Caco2 cells, RT-PCR was used to investigated the level of various tight junction proteins. Data represented the mean ± SEM of at least three independent experiments (*P < 0.05 vs. control Caco2 cells group; ##P < 0.01 vs. TNBS-damaged Caco2 cells group)Back to article page
