    TLDR The protein STAT3 slows down cell growth by blocking the FST gene, which affects hair development in sheep.
    The study "STAT3 Partly Inhibits Cell Proliferation via Direct Negative Regulation of FST Gene Expression" found that the STAT3 protein negatively regulates the FST gene, which is involved in hair follicle development and hair trait formation in sheep. This was demonstrated through various experimental methods, including a dual-luciferase reporter assay, chromatin immunoprecipitation assay, and cell proliferation assay. Overexpression of FST promoted cell proliferation, while overexpression of STAT3 showed the opposite effect. The study suggests that STAT3 could potentially be used as a therapeutic target for diseases characterized by abnormal cell proliferation. However, the study acknowledges limitations such as the use of cell lines not derived from hair follicles and the lack of in vivo testing. Future research is needed to validate these findings in a live sheep model.

      community So we’re just ok with taking a research chemical now?

      by Lonelyboy14 in Treatment  178 upvotes 3 years ago
      The conversation discusses the use of RU58841, a non-FDA approved research chemical for hair loss, with mixed opinions on its safety and effectiveness. Some users are willing to try it as a last resort after other treatments like Minoxidil and Finasteride failed, while others express concerns about potential long-term side effects and lack of official research.

      community Is 8% ru58841 significantly stronger than 5%

      A user increased their RU58841 treatment from 5% to 8% to combat hair loss and is questioning the effectiveness of the higher dosage. Another user shared their extensive hair loss treatment regimen, suggesting that while 8% RU58841 might not significantly change results, it's worth trying as individual responses vary.

      community My current nuclear stack. Thoughts?

      The user is using RU58841 twice daily, dutasteride 0.5mg every two days, dutasteride mesotherapy every three months, and 20mg oral minoxidil daily. Other users suggest this regimen is excessive and recommend adding microneedling and ketoconazole shampoo.
