Project description:Study to optimize our protocol for isolating RNA from skin biopsies from (hairless) SKH mice using different-diameter biopsy punches. Some mice were also treated with UVB radiation to check its effect on RNA yield. 4 mice total: 2 were irradiated with 300J/m2 UVB and 2 were non-irradiated. Post-mortem skin biopsies with 1.5mm, 2.0mm, and 2.5mm diameter punches were taken from the dorsal region.

Project description:Renin-angiotensin system regulates cell proliferation, differentiation, apoptosis and tissue remodeling in skin. Previouly, we reported that angiotensin-converting enzyme (ACE) expression and angiotensin II level were enhanced by repeated UVB-irradiation of hairless mice skin, and ACE inhibitor enalapril maleate accelerated recovery of UVB-induced wrinkle. In present study, we analyzed gene expression with DNA microarray and protein distribution with immunofluorecence method to clarify the process of wrinkle repairing with enalapril maleate in UVB-irradiated hairless mouse. In microarray analysis, we detected up-regulation of various extracullular matrix (ECM) genes and ECM related genes. In immunofluorescence, we confirm that type 1 collagen, fibrillin1, elastin, and dystroglycan 1 were decreased by repeated UVB-irradiation and the distribution of these components were improved by enalapril maleate treatment. In addition, ADAMTS2 and MMP-14, these were perticipate in ECM structure formation and degradation, were increased in enalapril maleate-treated mouse skin. While the functions of these molecules in skin is not clear yet, it is suggested that these molecules participate in improvement of wrinkles induced by UVB-irradiation. Male hairless mice of the SKH-1 strain were purchased from Charles River Laboratories Japan, Inc. (Tokyo, Japan). These animals were approximately 6 weeks old at the start of the experiment. They were fed a commercial diet (CRF-1, Oriental Yeast Co., Ltd, Tokyo, Japan) ad libitum and allowed free access to water. The dorsal region of the mouse was repeatedly irradiated with UVB for 10 weeks. Enalapril maleate treatment was started at 1 week after 10-week irradiation. One hundred microliters of 1% w/v enalapril maleate dissolved in 30 vol % ethanol solution or 30 vol % ethanol (control) was applied 5 times a week for 2 consecutive weeks to the whole dorsal skin of each of the mice. All experimental procedures using mice were approved by the Animal Experiment Committee of Tokyo University of Agriculture and Technology (approval number 24-82). The dosal region of the mouse was repeatedly irradiated with UVB for 10 weeks. Enalapril maleate treatment was started at 1 week after 10-week irradiation. One hundred microliters of 1% w/v enalapril maleate dissolved in 30 vol % ethanol solution or 30 vol % ethanol (control) was applied 5 times a week for 2 or 6 consecutive weeks to the whole dorsal skin of each of the mice. Each of the experimental groups comprised 6 mice. After 2- or 6-week drug treatment, skin samples were collected for microarray analysis.

Project description:The immune checkpoint ligand PD-L1 has emerged as a molecular target for skin cancer therapy and might also hold promise for preventive intervention targeting solar ultraviolet light-induced skin damage. Topical application of the small molecule PD-L1 inhibitor BMS-202 significantly modulates UV-induced inflammation in SKH-1 mouse skin as substantiated by NanoString CounterTM transcriptomic analysis.

Project description:ZnO and TiO2 nanoparticles can elicit a range of perturbed cell responses in vitro. Exposure to topically applied sunscreens containing ZnO or TiO2 particles may or may not elicit a biological effect in mice. We aimed to compare the biological responses of immune-competent hairless mice receiving topical applications of commercially available sunscreens with or without metal oxide nanoparticles, with the responses of mice receiving no sunscreen. Commercially available sunscreens containing ZnO nanoparticles, a mixture of TiO2 nanoparticles and organic UVR filters, or only organic UVR filters were applied to the backs of SKH:QS mice weekly over 36 weeks, with or without subsequent exposure to 29 kJ/m2 UVR. After 36 weeks and 30 treatments, mice were sacrificed and liver tissue was harvested for RNA isolation and whole genome transcriptional profiling, comparing the expression profiles of treated mice with untreated mice.
