The study found that fatty acid 2-hydroxylase (FA2H) was crucial for normal fur development and sebum production in mice. FA2H was specifically expressed in sebaceous glands and necessary for synthesizing certain lipids. Mice lacking FA2H had enlarged sebaceous glands, altered sebum composition, and experienced hair loss during the telogen phase due to blocked hair canals. This highlighted the role of FA2H in maintaining hair follicle homeostasis and the importance of specific lipids produced by sebaceous glands.

258 citations , 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.

research Epidermal Growth Factor as a Biological Switch in Hair Growth Cycle

94 citations , July 2003 in “Journal of biological chemistry/The Journal of biological chemistry”

This study found that continuous expression of epidermal growth factor in transgenic mice prevented hair follicles from entering the catagen phase, implicating EGF as a crucial regulator in hair cycle progression.

research Exogen, Shedding Phase of the Hair Growth Cycle: Characterization of a Mouse Model

107 citations , September 2002 in “Journal of Investigative Dermatology”

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.
