Abstract
The progression of androgenetic alopecia is closely related to androgen-inducible transforming growth factor (TGF)-${\beta}1$ secretion by hair follicle dermal papilla cells (DPCs) in bald scalp. Physiological levels of androgen exposure were reported to increase reactive oxygen species (ROS) generation. In this study, rat vibrissae dermal papilla cells (DP-6) transfected with androgen receptor showed increased ROS production following androgen treatment. We confirmed that TGF-${\beta}1$ secretion is increased by androgen treatment in DP-6, whereas androgen-inducible TGF-${\beta}1$ was significantly suppressed by the ROSscavenger, N-acetyl cysteine. Therefore, we suggest that induction of TGF-${\beta}1$ by androgen is mediated by ROS in hair follicle DPCs.
