    TLDR Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.
    The document "A Kaleidoscope of Keratin Gene Expression and the Mosaic of Its Regulatory Mechanisms" explores the complex regulation and expression of keratin genes, which are essential for the structural integrity and function of epithelial cells. It highlights the roles of chromatin compartmentalization, topologically associated domains (TADs), and transcription factors like KLF4 and CTCF in regulating keratin genes. The study discusses the dynamic interactions between enhancers and promoters during keratinocyte differentiation and the implications of keratin gene misregulation in diseases such as cancer and hereditary disorders. The research underscores the importance of understanding these regulatory mechanisms for potential therapeutic interventions.

      community Results of Procyanidin B2 in clinical studies

      in Treatment  12 upvotes 5 years ago
      Procyanidin B2, a compound derived from Annurca apples, as a potential treatment for pattern hair loss. Several clinical studies were mentioned, which found that procyanidin B2 could increase hair growth, density, and keratin content. Other treatments such as Minoxidil, Finasteride, and RU58841 were not discussed.

      community Keratin microspheres - breakthrough

      in Research/Science  14 upvotes 1 year ago
      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

      in Minoxidil  2 upvotes 4 months ago
      Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.
