Human hair follicles are self-renewing structures, which undergo three phase of hair cycle; anagen, catagen, and telogen. #946;-catenin, the transducer of Wnt signaling, is critical in development and growth of hair. In the absence of Wnt signals, cytoplasmic #946;-catenin is maintained at low level through regulation by GSK-3, multifunctional serine/threonin kinase. After phosphorylation by GSK-3, #946;-catenin is ubiquitinated and degraded in cytoplasm. Therefore, inhibition of GSK-3 is able to increase #946;-catenin in nucleus and would be able to induce growth of hair. Valproic acid (VPA) is an anticonvulsant and mood-stabilizing drug used for decades and is known to inhibit the GSK-3#946;. In our study, VPA enhanced the proliferation of human dermal papilla cells (DPCs) and outer root sheath (ORS) cells. When DPCs were treated with VPA, #946;-catenin was shown to be accumulated in the nucleus of DPCs by immunocytochemistry. Using human hair follicle organ culture, we found that hair follicles treated with VPA showed more rapid elongation of hair. Topical application of VPA on the back of 7 week old female C57BL/6 mice accelerated hair growth compared to control. In conclusion, we think that VPA can enhance hair growth through inhibition of GSK-3#946; and would become a potential alternative for treatment of alopecia.
