    研究背景与意义:结直肠癌(CRC)发生的分子机制尚不十分清楚,其发病原因和病因错综复杂,目前认为是在机体的内因与环境的外因相互作用的结果。近年来有越来越多的证据表明,结直肠癌干细胞的存在可能是导致肿瘤发生进展的重要原因之一。结直肠癌干细胞是肿瘤内非常小部分的细胞亚群,具有自我更新、形成异质性亚群,强耐药性并形成肿瘤的能力,因此它可能是肿瘤发生、耐药、转移和复发等各种恶性行为的源头。很多研究证实,Smad4作为TGF-β超家族信号通路中的关键分子,它的突变与结直肠癌的侵袭和转移密切相关,但是在结直肠癌干性中的调控机制尚不清楚。阐明Smad4对结直肠癌干性的影响及其信号调控机制,探索预防和治疗结直...Background and significance: The molecular mechanism of colon cancer is not very clear and its etiology and risk factors are very complex。Now, it’s thought that, the interaction consist of internal factors in the body and external factors in environment rusluts to the occurrence.
