February 2002 in “Carcinogenesis” The study used transgenic mice with targeted expression of spermidine/spermine N1-acetyltransferase (SSAT) in hair follicle keratinocytes to investigate susceptibility to skin cancer. These K6-SSAT transgenic mice, bred onto a tumor-resistant C57BL/6 background, showed a 10-fold increase in epidermal tumors when exposed to a carcinogenesis protocol involving 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate. The transgenic mice exhibited elevated SSAT activity and protein levels, along with increased putrescine and N1-acetylspermidine, indicating enhanced polyamine catabolism. The study concluded that this activation of polyamine catabolism might play a crucial role in chemically induced skin cancer, as evidenced by the early onset and progression to carcinomas in the transgenic mice.

February 1983 in “The Journal of Dermatology” The study investigated hair regrowth in C3H mice of varying ages by analyzing enzyme activities in different skin areas after shaving. It was found that hair regrowth was irregular and delayed as mice aged, with older mice showing more significant delays. In 59-day-old mice, 30-50% of the shaved area was covered with new hair nine days post-shaving. Biochemical analysis revealed that enzyme activities of ornithine decarboxylase (ODC), transglutaminase (TGase), and alkaline phosphatase (Al-P) were significantly higher in hair re-growing areas compared to non-growing areas. These enzyme activities were also elevated in follicle-rich fractions from re-growing areas compared to non-shaved areas, suggesting a link between these enzymes and hair growth.

September 2018 in “American Journal of Medical Genetics Part A” A 32-month-old Caucasian female was identified with a heterozygous de novo nonsense mutation in the ODC1 gene, leading to a new pediatric disorder characterized by developmental delay, alopecia, and other symptoms such as macrosomia and macrocephaly. This mutation resulted in elevated ODC protein and polyamine levels in red blood cells. The case confirmed similar symptoms observed in a transgenic ODC1 mouse model. The mutation was identified through whole-exome sequencing and confirmed by Sanger sequencing. The patient might benefit from treatment with α-difluoromethylornithine, an FDA-approved drug.
