research Activation of Polyamine Catabolism Profoundly Alters Tissue Polyamine Pools and Affects Hair Growth and Female Fertility in Transgenic Mice Overexpressing Spermidine/Spermine N1-Acetyltransferase
In this study, researchers created a transgenic mouse line that overexpressed spermidine/spermine N^1-acetyltransferase, leading to significant alterations in tissue polyamine pools. These changes included the presence of N^1-acetylspermidine, an unusual accumulation of putrescine, and reduced levels of spermidine and spermine. The most notable phenotypic effect was permanent hair loss in mice aged 3 to 4 weeks, associated with the formation of follicular cysts in the dermis, likely due to putrescine's interference with hair follicle cell differentiation and proliferation. Additionally, female mice were infertile, linked to ovarian hypofunction and underdeveloped uteri. This research highlighted the potential of using spermidine/spermine N^1-acetyltransferase overexpression to manipulate polyamine levels in transgenic animals for studying developmental and cancer-related outcomes.
research Fetal Alcohol Syndrome: Current Status of Pathogenesis
The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.
research Targeted Expression of Spermidine/Spermine N1-Acetyltransferase Increases Susceptibility to Chemically Induced Skin 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.
