June 2000 in “Japanese Journal of Cancer Research” The study investigated the effect of dimethylarsinic acid (DMA) on skin carcinogenesis in K6/ODC transgenic mice, which are more sensitive to carcinogens due to the overexpression of ornithine decarboxylase in hair follicle keratinocytes. Female C57BL/6J K6/ODC transgenic mice were treated with DMA after initiation with 7,12-dimethylbenz[α]anthracene (DMBA). The results showed that DMA significantly accelerated the induction of skin tumors, similar to the known tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA), indicating that DMA had a promoting effect on skin tumorigenesis in these transgenic mice.

April 1998 in “Journal of Investigative Dermatology” The study utilized a transgenic mouse model to evaluate the effectiveness of sunscreens in protecting against UVA-induced photoaging. The mice were exposed to PUVA to induce photoaging, and the study found that all tested sunscreens reduced CAT activity, indicating protection against UVA-induced damage. The combination of an SPF 15 sunscreen and a UVA filter provided the highest level of protection. The model demonstrated sensitivity and potential to simulate human cutaneous photoaging, highlighting the importance of UVA protection in sunscreens and suggesting that inflammation might play a role in elastin gene induction by UVA. The study emphasized the need for sunscreens with higher SPF ratings to incorporate more UVA protection.
