肠癌模型动物诱导剂

来源:作者:人气:-发表时间:2014-08-08 16:34:00【
诱发性肿瘤动物模型制作方法简便,重复性好,可以在较短时间内大量复制,而且基本模拟了癌变的过程,因此在实验中应用较广。诱发性大肠癌模型有较长的历史,目前建立大肠癌诱发模型用较多的试剂是二甲基肼(DMH)和氧化偶氮甲烷(AOM),甲基硝基亚硝基胍(MNNG)也是得到广泛应用的一种致癌物。
 
氧化偶氮甲烷(Azoxymethane)是一种对大鼠和小鼠具有强力诱发大肠癌作用的物质,用于氧化偶氮甲烷诱导致畸预防性治疗的有效性评估研究。氧化偶氮甲烷也用于确认某些啮齿动物模型所使用的特殊食物,例如难消化糖,红肉和绿茶的化学预防性能。这些啮齿动物模型可以帮助鉴别可预防人类大肠癌可能的手段。
