Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), significantly increases the risk for development of colorectal cancer. Specifically, dysplasia and cancer associated with IBD (colitis-associated cancer or CAC) develop as a result of repeated cycles of injury and healing in the intestinal epithelium. Animal models are utilized to examine the mechanisms of CAC, the role of epithelial and immune cells in this process, as well as the development of novel therapeutic targets. These models typically begin with the administration of a carcinogenic compound, and inflammation is caused by repeated cycles of colitis-inducing agents. This review describes a common CAC model that utilizes the pro-carcinogenic compound azoxymethane (AOM) followed by dextran sulfate sodium (DSS) which induces the inflammatory insult.
炎症性肠病(IBD),包括溃疡性结肠炎(UC)和克罗恩病(CD),会显著增加患结直肠癌的风险。具体而言,与IBD相关的发育异常和癌症(结肠炎相关癌或CAC)是由于肠上皮反复的损伤和愈合循环所致。动物模型用于研究CAC的机制、上皮细胞和免疫细胞在此过程中的作用,以及新型治疗靶点的开发。这些模型通常首先给予致癌化合物,通过反复给予诱导结肠炎的药物引发炎症。本综述描述了一种常见的CAC模型,该模型使用致癌前体化合物氧化偶氮甲烷(AOM),随后使用硫酸葡聚糖钠(DSS)诱导炎症损伤。
