Study of the role of glucocorticoid receptor-alpha and beta mRNA of the peripheral blood mononuclear cells in the pathogenesis and treatment of dermatomyositis/polymyositis / 中华风湿病学杂志

Objective To investigate the expression of glucocorticoid receptor-alpha and beta(GR?and GR?)mRNA of peripheral blood mononuclear cells(PBMCs)in patients with dermatomyositis/polymyositis (DM/PM)and analyze their association with the pathogenesis and clinical response to glucocorticoid therapy. Methods The expression of GR?and GR?mRNA in PBMCs from 20 normal controls and 36(24 steroid- sensitive,12 steroid-resistant)patients with DM/PM were detected by reverse transcription polymerase chain reaction(RT-PCR).Results Compared to normal controls,the expression of GR?mRNA in the DM/PM was significantly decreased(P
