December 2021 in “Scientific Reports” This study demonstrates that inhibiting class I histone deacetylases (HDACs) with MS-275 preserves hair follicle (HF) inductivity in postnatal dermal cells (DCs) during culture. Normally, DCs lose HF inductivity rapidly in vitro, but MS-275 maintains this ability by increasing histone H3 acetylation, which in turn upregulates HF inductive genes like BMP4, HEY1, and WIF1, and activates the Wnt signaling pathway. These findings suggest that targeting class I HDACs could be a promising strategy for inducing new HFs, offering potential therapeutic benefits for treating alopecia.
