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.

research A Case of Androgen-Secreting Adrenal Carcinoma with Non-Classical Congenital Adrenal Hyperplasia
A woman with a rare adrenal tumor and hormonal disorder had improved testosterone levels after surgery, but her menstrual irregularities continued.
research The Role of Anemia and Vitamin D Levels in Acute and Chronic Telogen Effluvium
Low iron levels are a significant risk factor for hair loss, while high vitamin D levels might be a response to hair loss, not a cause.
research Short-Term Biomarkers of Cigarette Smoke Condensate Tumor Promoting Potential in Mouse Skin
The study investigated the effects of cigarette smoke condensates (CSCs) on mouse skin, focusing on hyperplasia and inflammation as short-term biomarkers of tumor promotion. Using a truncated initiation-promotion protocol, the research assessed epidermal thickness, proliferative index, and ornithine decarboxylase (ODC) expression after CSC application. Results showed that CSCs increased these markers, with partial reversibility in interfollicular areas but sustained elevation in perifollicular regions. The study highlighted perifollicular ODC expression as a promising indicator for evaluating CSCs due to its rapid induction, low threshold, and potential to reflect irreversible changes, aligning with the notion that ODC expression is crucial for tumor promotion and that tumors primarily originate in the perifollicular epidermis.
research Steroid 17-Hydroxyprogesterone in Hair as a Potential Long-Term Biomarker of Androgen Control in Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency
