• cultured colon epithelium cells grown for 2 days under serum starvation exhibit a 3-fold decrease in the number of ciliated colon epithelium cells compared to controls
• however, MEFs grow primary cilia similarly to control MEFs decrease in the number of cilia per crypt in the colon
• colon epithelium shows a reduced number of primary cilia
|
• decrease in the number of cilia per crypt in the colon
|
• mice exhibit a higher proliferation rate in the colon that is coupled to a faster turnover of epithelial cells in the crypts
• histologically, however, colon tissue shows no obvious changes
|
• colon epithelium cells divide more rapidly, with 45% of colon epithelium cells containing >2n DNA compared to 20% of wild-type cells, indicating an increase in the number of cells that are in S or in G2 phase/metaphase of the cell cycle and a higher mitotic activity
|
• in a model of colitis-associated carcinogenesis (intraperitoneal injection of azoxymethane and subsequent periodic administration of dextrane sodium sulfate), mutants show an increase in tumor incidence, increased total number of lesions, and increased tumor size
