January 2021 in “Mediators of Inflammation” In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.
December 2025 in “Advanced Healthcare Materials” In this study, a new topical formulation containing amine-activated carboxymethyl chitosan and hydrolyzed extracellular matrix showed promising results in a mouse model by reducing oxidative stress, inflammation, and promoting hair regeneration, potentially offering an alternative treatment for inflammatory hair loss.
March 2026 in “The Journal of Steroid Biochemistry and Molecular Biology” This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.
