| Outline of Final Research Achievements |
Using a forward genetics approach to map loci in a mouse skin cancer model, we previously identified a genetic locus, Skin Tumor modifier of MSM 1 (Stmm1) on chromosome 7, conferring strong Tumor resistance. Here, we report that serum intact-PTH (iPTH) and a genetic polymorphism in Pth are important for skin Tumor resistance. We identified higher iPTH levels in sera from cancer-resistant MSM/Ms mice compared with susceptible FVB/NJ mice. Therefore, we performed skin carcinogenesis experiments with MSM-BAC transgenic mice (PthMSM-Tg) and Pth knockout heterozygous mice (Pth +/-). As a result, the higher amounts of iPTH in sera conferred stronger resistance to skin Tumors. Taken together, our data suggest that Pth is one of the genes responsible for Stmm1, and serum iPTH could serve as a prevention marker of skin cancer and a target for new therapies.
