research N1-methylspermidine, a stable spermidine analog, prolongs anagen and regulates epithelial stem cell functions in human hair follicles
N1-methylspermidine helps hair growth and reduces inflammation in hair follicles.
research Relation of Skin Polyamines to the Hairless Phenotype in Transgenic Mice Overexpressing Spermidine/Spermine N1-Acetyltransferase
Excessive putrescine causes hair loss in transgenic mice by disrupting hair follicle development.
research Adipocyte-Derived Amino Acid Storage Proteins are Required for Germline Stem Cell Maintenance in Adult Drosophila Females
Amino acid storage proteins are essential for maintaining stem cells in female fruit flies.
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
Overexpressing SSAT in mice makes them highly sensitive to polyamine analogues, causing liver damage and high mortality.
research The Effects of Finasteride on Pituitary-Testicular Hormone Axis and Spermatogenesis in Rat.
research The effects of Finasteride on the expression of Dazl, Tsga10, Sycp3, Prm2 genes during spermatogenesis in testes of NMRI mice
Finasteride, at doses of 5mg or higher, may negatively affect male fertility by reducing the expression of certain genes involved in sperm production.
research Effection of Epristeride and Finasteride on Spermatogenesis in Male Rats
Finasteride reduces sperm count and affects male reproductive function, while Epristeride does not.
research Disturbed Keratinocyte Differentiation in Transgenic Mice and Organotypic Keratinocyte Cultures as a Result of Spermidine/Spermine N1-Acetyltransferase Overexpression
