BAC-Mediated Gene-Dosage Analysis Reveals a Role for Zipro1 (Ru49/Zfp38) in Progenitor Cell Proliferation in Cerebellum and Skin

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

PP405 is a new topical drug that reactivates dormant hair follicle stem cells by inhibiting the MPC protein, shifting cell metabolism to glycolysis, and potentially regrowing hair even in bald areas. It differs from minoxidil and finasteride as it does not alter hormones or blood flow but instead targets cell metabolism.

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.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

CRISPR treatments for blood disorders have been approved, leading to discussions about its potential for treating hair loss (AGA). A study showed that editing a gene related to DHT sensitivity could lead to hair regrowth, suggesting CRISPR may eventually be used for AGA, but it's expected to be expensive and not soon available.

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.
