Research Abstract |
Human cyclin D1b gene generates two major isoforms, cyclin D1a and cyclin D1b by alternative splicing. Cyclin D1b, which lacks the ability to bind to CDK4 and phosphorylated Rb, is hardly expressed in normal tissues but is frequently expressed in certain types of cancer tissues including bladder cancers. To clarify the oncogenic potential of cyclin D1b variant, we engineered transgenic(Tg) mice with the human cyclin D1b transgene by pCAGGS promoter, which is able to ubiquitously express transgene. We found that rectal tumors including adenocarcinoma, sessile serrated adenoma(SSA), traditional serrated adenoma(TSA) and hyperplastic polyp(HHP) were generated in about 60% of female Tg mice. This Tg mouse would become a good model of colorectal carcinogenesis via the serrated pathway.
