507 Trial to Investigate the Role of ATP-Sensitive Potassium Channels in Dermal Papilla Cells

    November 2024 in “ Journal of Investigative Dermatology ”

    TLDR ATP-sensitive potassium channels are important for hair growth.
    The study investigates the role of ATP-sensitive potassium channels (KATPc) in dermal papilla cells (DPCs) by examining the effects of a novel Cantu syndrome-associated mutation and several loss-of-function mutations. These mutations were overexpressed in immortalized DPCs using a lentivirus vector. The DPCs were then induced to a hair-inducing state and cultured in a specific medium. Microarray analyses were conducted to compare mRNA expressions, and several candidate genes have been identified for future experiments. The research aims to better understand the function of KATPc in DPCs, which are crucial for controlling the hair cycle.

      community Creatine is the opposite of minoxidil !

      in Research/Science  322 upvotes 4 months ago
      Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.

      community Can liver problems be associated with response to the oral minoxidil?

      in Research  147 upvotes 1 month ago
      Liver problems may reduce the effectiveness of oral minoxidil due to impaired SULT1A1 enzyme activity, which is crucial for converting minoxidil to its active form. This reduction in enzyme function can significantly decrease the drug's effectiveness in promoting hair growth.

      in Treatments  371 upvotes 2 months ago
      A user in Egypt is seeking alternatives to oral minoxidil, which is banned there, after stopping topical minoxidil due to concerns for their cat's safety. Suggestions include drinking diluted topical minoxidil or making homemade minoxidil tablets, but these methods carry significant risks and are not recommended.

      community Is this Better Than Topical Minoxidil? Topical Diazoxide

      in Research/Science  6 upvotes 10 months ago
      Topical diazoxide may be a promising hair regrowth treatment, especially for those who don't respond to minoxidil, as it activates potassium channels without needing sulfation. It appears safe for topical use, avoiding systemic effects seen in oral use.

      community Occipitalis Muscle Tension Theory

      in Treatment  8 upvotes 1 month ago
      Scalp tension from the occipitalis muscle is theorized to contribute to hair loss, but most believe DHT and genetics are the main causes. Treatments like finasteride and minoxidil are considered more effective than addressing scalp tension.
