A Comprehensive Investigation Into the Molecular Mechanism Responsible for Selective Androgen Receptor Modulator Tissue-Selectivity

    The study investigated the molecular mechanism behind the tissue-selectivity of selective androgen receptor modulators (SARMs) by analyzing the conformation of the androgen receptor (AR) using various techniques. Despite initial challenges with biotinylation, further analysis revealed ligand-specific cofactors, notably identifying nuclear receptor corepressor (NCoR) exclusively in SARM-treated samples. This was confirmed by observing a higher degree of AR-SARM/NCoR association compared to AR-DHT/NCoR. Additionally, differences in cytoplasmic-nuclear transport and nuclear foci formation between AR-SARM and AR-DHT were noted. The findings suggested that AR-SARM complexes have distinct structural and functional properties, providing insights into the SARM tissue-selective mechanism and potential research directions.

      Finasteride users have mixed experiences with creatine; some experience increased hair loss, while others do not. Finasteride's DHT-blocking effects might counteract any DHT increase from creatine, but individual responses vary.

      A user humorously suggests an extreme hair loss treatment regimen involving multiple medications and therapies, including Dutasteride, Minoxidil, RU58841, and others, claiming it would prevent hair loss but with potential side effects like gynecomastia. The conversation highlights concerns about safety, side effects, and the effectiveness of such a comprehensive approach.
