ABSTRACT
Objective:To investigate the expression of aromatase of renal tissue in systemic lupus erythematosus(SLE)model mice.Methods:BALB/c mice were induced SLE with homologuous splenic cell activated with ConA after being ovariectomized,and in the same time administered different doses of benzestrofol.E2 in peripheral blood and renal tissue was detected by ELISA and the expression of mRNA of aromatase in renal tissue was detected by RT-PCR in the 4th,6th,8th and 10th weeks.Results:The level of E2 of peripheral blood and renal tissue of SLE model mice became higher as benzestrofol exogenously administered heightened.Compared with control mice,the level of E2 in SLE model mice increased,and the expression of mRNA of aromatase of renal tissue increased with E2 increment.Conclusion:E2 promotes development of SLE through regulating expression of aromatase mRNA.
