    TLDR The exact molecular mechanisms of sebaceous gland function are still unclear.
    The document reviewed the differentiation and morphogenesis of the sebaceous gland, emphasizing its role in skin barrier function and its relationship with hair follicles. It discussed the involvement of signaling pathways such as Wnt/β-catenin, Hedgehog, and c-myc in sebocyte proliferation and differentiation, and highlighted the significance of lipid metabolism, particularly stearoyl-CoA desaturase 1 (SCD1) and peroxisome proliferator-activated receptors (PPARs), in sebaceous gland function. Despite advancements in understanding these processes, the exact molecular mechanisms and their interactions remained unclear, necessitating further research to explore their contributions to skin diseases. The study used wholemounts of pilosebaceous units from mouse tail skin to illustrate these processes.

      community Is GT20029 supposed to regrow hair as well?

      in Treatment  10 upvotes 2 years ago
      The user is considering switching from finasteride to dutasteride for hair loss. They are unsure if GT20029 can regrow hair, particularly on the temples. Another user mentions that regrowth on finasteride can take up to 2 years.

      community For those who switched from finasteride to Dutasteride !

      in Chat  43 upvotes 2 years ago
      People discussed switching from finasteride to dutasteride for hair loss treatment. They reported satisfaction with dutasteride, noting it was more effective than finasteride, particularly after finasteride's effects diminished, and some experienced additional benefits like cost savings and stabilized hair loss, rating dutasteride highly as a treatment.

      community GT20029 China Phase II Trial For AGA Reached Primary Endpoint

      in Research/Science  135 upvotes 1 year ago
      The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.
