August 2013 in “Experimental Dermatology” The study explored the interaction between the nuclear protein Hairless (HR) and the polyamine putrescine in the epidermis, revealing a negative regulatory loop. Mutations in HR and overexpression of polyamine enzymes like ornithine decarboxylase (ODC) and spermidine/spermine N1-acetyltransferase (SSAT) led to hair loss and skin papules. The research showed that decreased HR levels resulted in increased ODC expression, and this regulation was influenced by the MYC superfamily of proteins. Elevated putrescine levels reduced HR expression, but the effects differed from HR mutations. Microarray analysis indicated that putrescine affected genes related to protein interactions and transcription, suggesting significant implications for epidermal homeostasis and hair follicle cycling.
