The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.
IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.
Hair loss treatments discussed include Minoxidil, Finasteride, and RU58841. Anageninc stopped selling KX-826 (Pyrilutamide) due to a cease and desist letter from Kintor, but this may indicate promising study results and a potential 2024 release.
SCUBE3, a protein linked to hair growth in moles, was discovered over 25 years ago and is being developed by Amplifica for potential hair loss treatment. Concerns exist about SCUBE3's association with cancer, as it is a protein that promotes cell growth, which could potentially trigger cancer development if used for hair growth therapy.
TGF-B affects hair growth, both causing stem cell division and death depending on amounts. Amplifica's treatment injects Scube3 to increase TGF-B for hair growth.
PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.
