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.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
community Fin/Dut shed + other questions
The user is preparing for potential future hair loss treatments and currently uses topical minoxidil, derma rolling, and ketoconazole shampoo. They are concerned about shedding, side effects, and the possibility of starting finasteride or dutasteride along with testosterone.
community Other sulfurtransferase activity upregulator other than Tretinoin?
The user does not respond well to minoxidil and is seeking an alternative to Tretinoin to upregulate sulfurtransferase activity for hair loss treatment. No specific alternative treatments were mentioned.
community Cell senescence-targeted treatment for hair loss, has anyone tried any products/enzymes etc. that use this theory
DHT causes hair loss by driving cells into senescence, and a polyphenol in black chokeberry may reverse this. A product using this theory is being considered for use alongside finasteride, minoxidil, and microneedling.
community Is it still beneficial to use a derma roller after switching to oral min?
Switching from topical to oral minoxidil and whether to continue microneedling. Users suggest using a derma stamp instead of a roller for better results and safety, and some recommend combining it with oils like rosemary.
