    TLDR Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.
    The 1984 study "Tumor Promotion in Skin: Are Active Oxygen Species Involved?" investigated the role of active oxygen species in skin tumor promotion. The researchers found that wounding or treatment with chemical irritants accelerated tumor development in mouse skin. They also found that phorbol ester tumor promoters led to a hyperplastic state in the skin, which is a general response to irritation and damage. The study also explored the role of TPA (Tetradecanoylphorbol acetate) in skin tumor promotion, noting that TPA treatment induced inflammation and hyperplastic growth, key symptoms of tumor promotion. However, the exact mechanisms and pathways involved were not fully understood. The study found indirect evidence suggesting that active oxygen species might be involved in tumor promotion, but no evidence existed for a critical role of active oxygen species in stage I of promotion. The role of active oxygen species in stage II of promotion remained unclear. The researchers also found conflicting results regarding the effects of non-steroidal anti-inflammatory agents on skin tumor promotion. The study concluded that understanding the wound response could provide insights into the mechanisms of skin tumor promotion.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      community Verteporfin and Microneedling

      in Treatments 6 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      community Treatment of Male Pattern Baldness with Botulinum Toxin

      The conversation discusses using Botox to treat male pattern baldness, suggesting it may promote hair growth by increasing scalp blood flow and oxygen, reducing dihydrotestosterone levels. The user wonders why this treatment is not widely discussed or if it has been discredited.
