540-570 / 660 resultsresearch The Rational Role Of Polyamines In Epidermal Differentiation
The study by Rahim et al. (2021) demonstrated that the balance of polyamine ratios, specifically the reduction of putrescine and increase of spermine regulated by AMD1, played a critical role in keratinocyte differentiation and epidermal homeostasis. This shift was essential for managing hyperproliferative skin disorders like psoriasis and skin cancer. The research suggested that activating AMD1 could be a promising therapeutic strategy, highlighting the importance of focusing on polyamine balance rather than total levels in treating these conditions.

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.
