自氧化偶氮甲烷（AOM）-硫酸葡聚糖硫酸鈉（DSS）誘導(dǎo)腫瘤用于研究炎癥相關(guān)或散發(fā)性結(jié)直腸癌（CRC）以來,數(shù)種AOM、DSS處理方式被報導(dǎo)。本文優(yōu)化了AOM-DSS誘導(dǎo)C57BL/6小鼠散發(fā)性結(jié)直腸癌模型的方法。利用100μl消毒注射器按照需要劑量一次性腹腔注射適當(dāng)濃度AOM,DSS處理7天并每天更換新鮮的DSS液體。我們共誘導(dǎo)超過100只小鼠,AOM處理后8至20周時,發(fā)現(xiàn)每只小鼠均被誘導(dǎo)發(fā)生結(jié)直腸腫瘤。腫瘤分布以結(jié)直腸遠(yuǎn)端居多,與人類結(jié)直腸癌相似。采用此方法建模的每只小鼠的成瘤數(shù)量較多、鼠間腫瘤數(shù)量差異較小。此AOM-DSS模型中的腫瘤病變涵蓋了瘤前病變、腺瘤性病變、腺瘤以及腺癌。本改良的AOM-DSS結(jié)直腸癌建模方法具有簡單、經(jīng)濟(jì)、成瘤率高等優(yōu)點。
