    TLDR Non-coding RNAs help control hair growth cycles in cashmere goats, suggesting ways to improve cashmere production.
    The study conducted an integrative analysis of non-coding RNAs (ncRNAs) to understand their roles in secondary hair follicle regression in cashmere goats. Researchers examined skin samples from three goats during different hair follicle stages, identifying 1122 known and 403 novel long non-coding RNAs (lncRNAs), with 173 showing differential expression, and 411 known and 307 novel microRNAs (miRNAs), with 72 differentially expressed. The study highlighted the synergistic role of lncRNAs and miRNAs in hair follicle growth transitions, particularly noting the regulation of catagen inducers TGFβ1 and BDNF by miR-873 and lnc108635596. The findings provided insights into the molecular mechanisms of hair follicle cycles, emphasizing the importance of ncRNAs in biological processes such as apoptosis and growth, and suggested potential molecular breeding strategies to improve cashmere production by preventing or delaying hair loss.

      community Journey against alopecia - Finasteride 3 month

      in Progress Pictures  17 upvotes 4 years ago
      A 26-year-old man from France started experiencing hair loss in September 2020 and began using finasteride in June 2021, reporting some improvement after three months without side effects. He plans to continue finasteride for a year before considering additional treatments like minoxidil or dermarolling.

      community My Current Hairloss Stack (No Finasteride)

      in Update  12 upvotes 2 years ago
      Hair loss treatments, specifically Minoxidil, Fluridil & Alfatradiol, Nizoral, Saw Palmetto, Hairmetto and Microneedling. The user mentioned they have seen a decrease in shedding and improvement in the quality/density of their hair since using this stack, but opted out of trying Finasteride due to potential side effects.

      Pyrilutamide, a potentially effective hair loss treatment; other topical treatments like RU58841 and CB-03-01 that may have fewer side effects than Pyrilutamide; and the Phase 3 clinical trials of Pyrilutamide, which is likely to be approved by the FDA soon.

      A 23 year old user who has had success with finasteride and minoxidil, regaining their hair after losing it due to male pattern baldness. They also attribute part of the success to lifestyle changes such as eating better, exercising, sleeping well, and reducing smoking.

      Hair loss treatments, specifically the use of finasteride, microneedling and potentially oral minoxidil. People discussed their experiences with finasteride, its effects on sexual behaviors, as well as potential solutions such as tadalafil or using other growth factor signal peptides for hope in curing male pattern baldness.
