ISX9, a Small Molecule Targeting Axin, Activates Wnt/β-Catenin Signaling and Promotes Hair Regrowth

This study found that ISX9 may activate the Wnt/β-catenin signaling pathway and holds potential as a therapeutic agent for treating alopecia.

In this study, researchers developed a novel temperature-sensitive biopolymer-based drug delivery system that enhanced the transdermal delivery of ISX9, a neurogenesis inducer, resulting in more effective hair follicle regrowth and signal pathway activation in vivo compared to traditional topical application.

This study identified nine compounds that activate Wnt signaling, with aminoacridine and proflavine especially promoting hair and nail regeneration in mouse models, highlighting new therapeutic candidates from existing FDA-approved and natural compounds.

This study found that inhibiting the interaction between CXXC5 and Dishevelled could stimulate hair regrowth in mouse models by enhancing WNT/β-catenin signaling, suggesting a potential therapeutic strategy for hair loss involving compounds that block this interaction, such as interfering short peptides.

In this study, knockdown of XIST in 3D-cultured dermal papilla cells inhibited hair follicle regeneration by interfering with miR-424 and hedgehog signaling, highlighting XIST's role in hair development.
