5 / 1000+ resultsresearch Metabolic pathway of Cis-UCA upon Ultraviolet B (UVB) exposure using ¹H Nuclear Magnetic Resonance (NMR) spectroscopy, Molecular Docking and cell viability of human keratinocytes (HaCaT) cell lines
This study investigates the metabolic pathway of cis-urocanic acid (cis-UCA) upon UVB exposure, using NMR spectroscopy, molecular docking, and cell viability assays with human keratinocytes (HaCaT). The research reveals that cis-UCA can react with reactive sulphur species (RSS) donors without the involvement of the glutathione-S-transferase (GST) enzyme, leading to the formation of a new compound, 4-imidazoleacrylic acid-3-thiol. The study also finds that the formation of glutathione and cysteine conjugates can occur non-enzymatically, challenging the previously proposed GST-dependent pathway. Molecular docking shows that the glutathione conjugate has a higher binding affinity with GST than sulforaphane, suggesting a regulatory role. In vitro studies demonstrate that UVB exposure with cis-UCA reduces cell viability, but the presence of sulphide donors mitigates this toxicity, highlighting their protective role. This research provides new insights into cis-UCA metabolism and suggests an alternative RSS-driven pathway, impacting our understanding of UCA's role in UVB-induced skin reactions.

The conversation is about using vitamin C and Magnesium L-Threonate for hair growth by reducing DHT binding to dermal papilla cells. The original post about vitamin C's pH levels and sebum control was possibly removed by a moderator.
community What Works to Restore Hairloss for Cis-Males? Not Much
Hair regrowth treatments for cis-males include Minoxidil, Finasteride, and RU58841. Estrogen and testosterone blockers can help restore hair loss but may not suit everyone.
community DNA Trichotest reliable? & topical spironolactone for Cis males
The DNA Trichotest is considered unreliable for predicting hair loss treatment responses, and topical spironolactone is questioned for its effectiveness and safety in cis males. Finasteride and Dutasteride are recommended as more reliable treatments for androgenic alopecia.
community FtM: "Aggressive Regemin - Recovery From Norwood-6.5" Minoxodil/Estradiol valerate/Spironolactone. (What will happen in the worst case if CIS male go this way for a year?)
User "Ant1pal" shares progress pictures of hair regrowth using Minoxidil, Estradiol valerate, and Spironolactone. Users discuss potential side effects and the possibility of localizing estrogen to hair follicles for better treatment.
community HRT is literal black magic. Fin 1 mg/day @ 4 years, min 2x/day @ 3 years, Estradiol 4mg/day @ 3.5 months, and Spironolactone 100mg/day @ 3.5 months (estra & spiro are medicines you should likely not take if you are a cis man)
User shared progress on hair regrowth using Fin 1 mg/day for 4 years, Min 2x/day for 3 years, Estradiol 4mg/day, and Spironolactone 100mg/day for 3.5 months. They noted significant hairline recovery and advised against HRT for cis men due to feminizing effects.
