The study involved generating a transgenic mouse line overexpressing the SSAT gene under a mouse metallothionein I promoter, leading to significant changes in tissue polyamine pools and delayed permanent hair loss compared to previous models. The liver was notably affected, with altered polyamine levels. Despite high SSAT mRNA levels, enzyme activity was only moderately increased unless induced by ZnSO4 or the polyamine analogue DENSPM, which caused a dramatic increase in enzyme activity and depletion of liver polyamines, resulting in high mortality and liver damage. The findings suggested that SSAT overexpression made the mice highly sensitive to polyamine analogues, indicating a post-transcriptional regulation mechanism.
research Medical Therapy for Frontal Fibrosing Alopecia: A Review and Clinical Approach
Some treatments like intralesional steroids and 5α-reductase inhibitors are effective for frontal fibrosing alopecia, but more research is needed.
research Disturbed Keratinocyte Differentiation in Transgenic Mice and Organotypic Keratinocyte Cultures Due to Spermidine/Spermine N1-Acetyltransferase Overexpression
Overexpression of spermidine/spermine N1-acetyltransferase (SSAT) in transgenic mice led to putrescine accumulation in the skin, resulting in permanent hair loss by 3 weeks of age, with hair follicles replaced by dermal cysts and epidermal utriculi. This condition mirrored hyperproliferative cutaneous disorders like psoriasis, characterized by delayed epidermal differentiation and altered expression of differentiation markers. Immunohistological analysis confirmed disturbed differentiation in SSAT transgenic skin, and similar changes were observed in organotypic cultures of transfected rat epidermal cells. Reducing putrescine levels through biosynthesis inhibition alleviated skin changes and allowed hair regrowth, indicating that keratinocyte differentiation disorders were responsible for the cutaneous changes in SSAT transgenic mice. This highlighted the importance of polyamine metabolism regulation in keratinocyte maturation.

research Overexpression of Spermidine/Spermine N1-Acetyltransferase Under the Control of Mouse Metallothionein I Promoter in Transgenic Mice: Evidence for a Striking Post-Transcriptional Regulation of Transgene Expression by a Polyamine Analogue
The study involved generating a transgenic mouse line overexpressing the SSAT gene under a mouse metallothionein I promoter, leading to significant changes in tissue polyamine pools and delayed permanent hair loss compared to previous models. The liver was notably affected, with drastic reductions in spermine and increases in putrescine. Despite high levels of SSAT mRNA, enzyme activity was only moderately elevated unless induced by ZnSO4 or the polyamine analogue DENSPM, which caused a massive increase in enzyme activity and depletion of spermidine and spermine pools. This treatment led to high mortality and liver damage, indicating that SSAT overexpression made the mice highly sensitive to polyamine analogues, suggesting a post-transcriptional regulation mechanism.
