描述:
claudin 2 Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity. Belongs to the claudin family. Can form homo- and heteropolymers with other CLDN. Homopolymers interact with CLDN3, but not CLDN1, homopolymers. Directly interacts with TJP1/ZO-1, TJP2/ZO-2 and TJP3/ZO-3

After Cr(VI) treatment, Zo- 2 and occludin protein levels were examined via Western blot analysis (A), and the relative ratios of Zo-2 and occludin were quantified in a histogram (B and C). Histopathological changes in the small intestine (D). IHC staining of Zo-1 and claudin-2 (E and F). The first lines of D, E, and F were the respective control groups (I and II), and the second line corresponded to 40 mg/kg Cr groups (III and IV). Higher magnification images of the outlined area are shown on the right (II and IV). Cr(VI)-induced oxidative damage in the small intestine of mice (G–I). Small intestinal homogenate samples were collected to examine the levels of SOD (G), MDA (H), and GSH-Px (I). Values in the same column with different superscripts (a, b, c, d) significantly differed and represented as mean ± SD. Differences with p < 0.05 were presented. All experimental data were obtained from three independent experiments.
