Fig. 5. Effects of GTP on tight junction protein regulation. The mRNA levels of OCLN (A) and TJP1 (B). (C) Representative images of colon tissues stained for OCLN by IHC and the density of OCLN. (D) Representative images of colon tissues stained for TJP1 by IHC and the density of TJP1. Images are at ×400 magnification, scale bar=50 μm. Values are presented as mean±standard error (n=6). Different letters (a-d) indicate significant differences (P<0.05) among groups, as determined using one-way ANOVA with Tukey’s multiple comparison tests. DSS, dextran sulfate sodium; GTP, green tea and java pepper mixture; OCLN, occludin; IHC, immunohistochemistry; TJP1, zonula occludens 1.
