July 2005 in “Journal of lipid research” This study found that DGAT1 exhibits additional acyltransferase activities in vitro, including MGAT, wax synthase, and ARAT activities, suggesting these could be relevant to its in vivo functions.
91 citations
,
November 2008 in “Journal of biological chemistry/The Journal of biological chemistry” This study found that DGAT1 functions as a key enzyme in murine skin to regulate retinoic acid levels and prevent retinoid toxicity, impacting hair cycle and sensitivity to retinol.

February 2021 in “Frontiers in Cell and Developmental Biology” This study suggests that vitamin A may inhibit hair follicle stem cells during refractory telogen in a dose-dependent manner, based on retinyl ester levels and vitamin A metabolism protein localization in mice.
This study found that the enzyme encoded by Dgat1 acts as a retinol acyltransferase in murine epidermis, protecting against retinoid toxicity and alopecia by preventing retinol accumulation.
