androgenetic alopecia STEAP3 protein minoxidil 5α-reductase inhibitors AR gene EDA2R gene HDAC9 gene PAX1 gene FOXA2 gene GSK3β β-catenin AGA Rogaine Propecia

TLDR STEAP3 protein might help treat hair loss, but more testing is needed.

The document presents a theoretical model for treating androgenetic alopecia (AGA) using the STEAP3 protein, based on recent genetic insights into the condition. Current treatments like minoxidil and 5α-reductase inhibitors have limitations and side effects. The study reviews genetic mutations in genes such as AR, EDA2R, HDAC9, PAX1, and FOXA2, which are involved in various molecular pathways. The proposed model suggests that STEAP3 could inactivate GSK3β, allowing β-catenin to enter the cell nucleus, potentially addressing the root cause of AGA. However, this model is purely theoretical and requires further laboratory and clinical validation.
