Effects of rhein on intestinal epithelial tight junction in IgA nephropathy

Table 2 Grey level of occludin and zona occludens protein-1 in Western blotting

	Control group	IgAN group	Rhein-treated group	Rhein-prevented group
Occludin	1.38 ± 0.31	0.72 ± 0.15b	1.15 ± 0.17d	1.34 ± 0.21d
ZO-1	1.98 ± 0.43	0.85 ± 0.12b	1.57 ± 0.23ad	2.07 ± 0.41df

The results were normalized to the respective β-actin expression.

^aP < 0.05,

^bP < 0.01 vs control group;

^dP < 0.01 vs IgA nephropathy (IgAN) group;

^fP < 0.01 vs Rhein-treated group.
