Mitochondrial DNA mutations in human colonic crypt stem cells.
The mitochondrial genome encodes 13 essential subunits of the respiratory chain and has remarkable genetics based on uniparental inheritance. Within human populations, the mitochondrial genome has a high rate of sequence divergence with multiple polymorphic variants and thus has played a major role in examining the evolutionary history of our species. In recent years it has also become apparent...
متن کاملFluctuations of cell population in a colonic crypt.
The number of stem cells in a colonic crypt is often very small, which leads to large intrinsic fluctuations in the cell population. Based on the model of cell population dynamics with linear feedback in a colonic crypt, we present a stochastic dynamics of the cell population [including stem cells (SCs), transit amplifying cells (TACs), and fully differentiated cells (FDCs)]. The Fano factor, c...
متن کاملInfluence of rofecoxib on experimental colonic carcinogenesis in rats.
AIM To investigate the effect of a selective cyclooxigenase-2 (COX-2) inhibitor, rofecoxib, in the prevalence of experimental colon tumors in rats. EXPERIMENTAL DESIGN Experimental study with 35 male Sprague-Dawley rats, divided into four groups: a) control group without experimental manipulation (n = 5); b) pharmacological carcinogenesis with 1-2 dimethylhydrazine dihydrocloride (n = 10); c)...
متن کاملKinetic changes in mucosal ornithine decarboxylase activity during azoxymethane-induced colonic carcinogenesis in the rat.
In the azoxymethane (AOM)-treated rat model of colonic carcinogenesis, serial injections of the carcinogen lead to the eventual development of colonic tumors. However, the precise nature of carcinogenesis events in this commonly used model is not well defined, and the occurrence of classic initiation and promotion phases after serial injections is uncertain. Since increases in ornithine decarbo...
متن کاملIncreased proliferation of middle to distal colonic cells during colorectal carcinogenesis in experimental murine ulcerative colitis.
Patients with ulcerative colitis (UC) exhibit an increased risk for the development of cancer of the colon and rectum. This association is widely attributed to colonic inflammation. However, the severity of colonic inflammation necessary for the development of dysplasia and/or cancer remains unknown. In this study, we investigated the pattern of cell proliferation in colorectal carcinogenesis i...
