Effect of the 13-cis isotretinoin on androgen receptor levels in acneic patients / 中华医学美学美容杂志

ABSTRACT

Objective　In order to explore the effect of 13-cis isotretinoin on androgen receptor in acneic patients and provide the theoretical basis for acne treatment. Methods　Radiological binding assay (RBA) was used to study the specific AR binding capacities between the experimental group and the control group before and after taking medicine. The serum testosterone level was measured with radioimmunoassay. Results　 16 weeks after taking medicine, the AR level in the acne patients decreased significantly compared with that before taking 13-cis RA (P＜0.05)，but the affinity change was not found, the testosterone levels did not evidently change either. Conclusion　The 13-cis RA can decrease the levels of AR and depress the hyperplasia of sebaceoous glands.
