ABSTRACT
<p><b>OBJECTIVE</b>To explore the action mechanism of Jiedu Quyu Zishen Recipe (JQZR) on the signal transduction of glucocorticoid receptor alpha (GRalpha) in the renal tissue of MRL/lpr mice.</p><p><b>METHODS</b>Thirty MRL/lpr mice were randomly divided into three groups, i.e., the model group, the Western medicine group, and the Chinese medicine group, 10 in each. Besides, another 10 Kunming mice was taken as the normal control group. The pathological changes of the renal tissue were observed using HE staining. The expression of GRalpha was analyzed using Real-time PCR and Western blot. The effects of JQZR on the binding power of GRalpha to cyclophilin A were detected using co-immunoprecipitation.</p><p><b>RESULTS</b>The renal injury degree of MRL/lpr mice in the Western medicine group and the Chinese medicine group was alleviated. Compared with the model group, the relative quantitation of GRalpha mRNA and protein expressions in the renal tissue of mice in the Western medicine group decreased, while they increased in the Chinese medicine group, showing statistical difference (P < 0.01). JQZR could significantly elevate the binding potency of GRalpha to cyclophilin A.</p><p><b>CONCLUSION</b>Up-regulating the expression of GRalpha and enhancing mutual actions of GRalpha and cyclophilin A was one of JQZR's effects on improving the lesion of the renal tissue.</p>
