July 2020 in “Synthetic and Systems Biotechnology” This study found that the cytochrome P450 enzyme CYP-sb21 can hydroxylate cyclosporine A at multiple positions, reducing its immunosuppressive effects but retaining its hair growth-promoting side-effect, and suggests modifications to improve regioselectivity for commercial use.
September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.
December 2023 in “International journal of molecular sciences” This in vitro study found sex chromosome differences affect steroidogenic enzyme activity and androgen receptor expression in human skeletal muscle cells, showing varied responses to testosterone exposure between 46XY and 46XX cells.

June 2018 in “Archives of Toxicology” This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.
