结直肠癌是我国常见的胃肠道恶性肿瘤,其发生发展是多阶段、多步骤的病理过程,与多个癌基因的激活及抑癌基因的失活有关。但是其真正的病因、关键性基因、基因调控的确切机制尚未完全明了。最近发现的定位于染色体3p21.3的抑癌基因RASSF1A(Ras association domain family1isofo
Colorectal cancer is a common gastrointestinal cancer in our country. The occurrence and development of colorectal cancer is a multi-stage and multi-step pathological process, which is related to the activation of multiple oncogenes and the inactivation of tumor suppressor genes. But the exact cause of the disease, the key gene and the exact mechanism of gene regulation are not fully understood. Recently found in the chromosome 3p21.3 tumor suppressor gene RASSF1A (Ras association domain family1isofo
