Snail2: Structure-Function Studies and In Vivo Analysis of Its Role in Hair Follicle Development and Chemical Skin Carcinogenesis

    TLDR Snail2 is crucial for hair growth and affects skin cancer development.
    The study investigated the roles of Snail1 and Snail2 transcription factors in epithelial-to-mesenchymal transition (EMT), hair follicle cycle, and skin carcinogenesis. It was found that Snail1 and Snail2 require different zinc fingers (ZFs) for their function, with Snail1 needing ZF1 and ZF2, and Snail2 requiring ZF3 or ZF4. The SNAG domain of Snail2 was crucial for EMT induction, while the SLUG domain negatively affected this process. In Snail2 knockout mice, the absence of Snail2 altered the hair follicle cycle and increased tumoral progression in skin carcinogenesis, particularly due to its absence in myeloid progenitors. The study highlighted the importance of Snail2 gene dosage in skin cancer response.

      A 24-year-old reported new hair growth on temples after 3.5 months of using topical minoxidil without shedding. They plan to add finasteride to maintain progress, as minoxidil alone may not be enough long-term.

      Dutasteride is often blamed for worsening hair loss, but initial shedding may lead to improvement, requiring patience. Some users find success with dutasteride, finasteride, and minoxidil, while others experience side effects or no improvement.

      community Don't give up on finasteride folks

      in Finasteride/Dutasteride  285 upvotes 10 months ago
      Finasteride may take over two years to show results and can cause side effects like sexual dysfunction and emotional changes. Alternatives such as dutasteride and minoxidil are discussed, with varying effectiveness and side effects.
