research Co-Operation Between Follicular Ornithine Decarboxylase and v-Ha-ras Induces Spontaneous Papillomas and Malignant Conversion in Transgenic Skin
The study demonstrated that elevated levels of ornithine decarboxylase (ODC) and polyamines, when combined with a mutant Ha-ras gene, led to spontaneous tumor development in double transgenic mice. These mice, which were bred to carry both K6/ODC and v-Ha-ras transgenes, developed well-differentiated keratoacanthomas, some of which progressed to carcinomas within 2 months. The tumor development was dependent on ODC, as the use of the ODC inhibitor DFMO prevented tumor formation and caused regression. This indicated that ODC overexpression and activated Ha-ras were sufficient for malignant transformation, providing a model to study epithelial tumor development without chemical carcinogens or tumor promoters.
research Hair: Its Structure and Response to Cosmetic Preparations

research Histologic Changes in the Skin of Hairless Mice Following Peeling With Salicylic Acid
The study investigated the histologic changes in the skin of hairless mice after applying salicylic acid solutions at concentrations of 7.5%, 15.0%, and 30.0% for 20 minutes. The solutions were prepared in either ethanol or macrogol. The skin was examined immediately and at intervals of 1, 3, 12, 24, and 48 hours post-treatment. The research aimed to understand the effects of salicylic acid used in chemical peeling, which was known to be effective without causing wounds or inflammation. The findings provided insights into the histologic alterations induced by different concentrations of salicylic acid over time.
research Two Distinct Signaling Pathways in Hair Cycle Induction: Stat3-Dependent and Independent Pathways
