Abstract:
[ABSTRACT]AIM:Toestablishatransgenicheterozygousmousemodelofprecancerouslesionsofcolorectal cancer with p110δmutation in the C57BL/6J background for serving the studies on colorectal cancer research mediated by p110δ.METHODS:The transgenic heterozygous mice were generated by crossing in p110δD910A/D910A mouse and ApcMin/+mouse, and the genotype was detected by PCR .Compared with ApcMin/+mice, transgenic heterozygous mice ( ApcMin/+;p110δD910A/D910A)were counted, and the number and size of intestine polyps were analyzed after methylene blue staining . The intestinal tissue structure was assessed by HE staining .RESULTS:The transgenic heterozygous mouse model of pre-cancerous lesions of colorectal cancer with p 110δmutation was established .The number and size of polyps in the transgenic heterozygous mice were declined .CONCLUSION: A transgenic heterozygous mouse model of precancerous lesions of colorectal cancer with p 110δmutation was successfully established .The initial phenotype of intestinal tumors in transgenic mice was observed .This model will greatly contribute to the related research of colorectal cancer in mice .
