PARK7 Diminishes Oxidative Stress-Induced Mucosal Damage in Celiac Disease

Figure 5

Damage of cell adhesion in epithelial cells induced by oxidative stress. Colocalization of actin (red) and zonula occludens 1 (ZO-1, green) was investigated by immunofluorescence staining (a) in FHs74Int duodenal epithelial cells after treatment with H2O2 (1000 μM) in the absence or presence of Comp23 (0.001 μM). Cell nuclei were counterstained with DAPI (blue). Scale bar: 50 μm. Relative mRNA expressions (b) in FHs74Int cells were determined by comparison with 18S ribosomal RNA as an internal control. Results are presented as (). vs. control+Ø compound (Mann-Whitney test); vs. H2O2+Ø compound (Mann-Whitney test).
