    TLDR K_ATP channel gene mutations are linked to heart diseases, but more research is needed to understand the connection and treatment potential.
    The document from 11 years ago discusses the association between ATP-sensitive potassium (K_ATP) channels and cardiovascular diseases, with a focus on the genetic underpinnings of such conditions. It details the structure and function of K_ATP channels, which are composed of Kir6 subunits and sulfonylurea receptor (SUR) subunits, and their role in protecting cardiac cells under metabolic stress. The paper reports on the connection between mutations in the SUR2 gene and Cantu syndrome, a multi-organ disorder with cardiovascular manifestations. It also mentions the use of K_ATP channel openers like minoxidil for hair growth and the potential of K_ATP channel inhibitors as treatments for conditions like Cantu syndrome. The document concludes that while there is evidence of K_ATP channel gene mutations in human cardiovascular diseases, more research is needed to confirm causality and explore therapeutic applications.

      community KX-826: Long-Term Safety Results are out!

      in Research/Science  158 upvotes 1 month ago
      KX-826 initially improves hair growth but declines after 24 weeks, with mild itching as a side effect. Combining it with minoxidil and finasteride may improve results, but long-term effectiveness is uncertain.

      community C’est terrible - at my wits end

      in Female  443 upvotes 1 year ago
      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.

      community Pyrilutamide - your experience?

      in Product  12 upvotes 1 year ago
      The conversation is about the lack of improvement in hair loss after using Pyrilutamide for 14 weeks, with the original poster unable to use Finasteride due to depression. Replies suggest that Pyrilutamide, like RU58841, may not work for everyone, and a more potent drug is being developed by Kintor.
