    TLDR Loss of the Y chromosome and UTY gene activity increases cancer risk in men.
    The commentary discusses the molecular mechanisms and health implications of Y chromosome loss (LoY), focusing on the UTY gene's role. UTY, a paralog of UTX on the X chromosome, encodes a protein involved in transcription repression through interactions with TLE1 and RUNX1. The loss of UTY disrupts these interactions, potentially leading to immature T cells and contributing to diseases like acute myeloid leukemia (AML) and T-cell acute lymphoblastic leukemia (T-ALL). The commentary highlights the need for further research into UTY's functions and interactions, particularly its demethylase activity and the potential compensatory role of KDM6B on chromosome 17. The authors emphasize that understanding these mechanisms could provide insights into the broader health impacts of LoY in males.

      community Hair loss and ethnicity - Caucasian men the most likely to experience hair loss

      in Chat  17 upvotes 1 year ago
      The conversation discusses how Caucasian men are more likely to experience hair loss due to genetic predisposition, with factors like the androgen receptor on the X chromosome playing a significant role. The user also expresses confusion about the evolutionary reasons for hair loss, especially in colder climates where it would seem beneficial to retain hair for warmth.

      User TopBack56 and friends tried pyrilutamide (KX-826) for hair loss without experiencing negative side effects. They observed fine vellus hairs but no thick hair growth yet, and plan to add GT20029 to their regime after safety trials.
