* p53蛋白抑制ras、c-myc等癌基因的转化作用,调节DNA合成的启始 很多人类的实体癌均有p53基因的突变,约70-80%的大肠癌有p53基因的突变 * CRP:C反应蛋白 * AFP具有运输大分子进入细胞、胚胎发育过程中的基因调控、生长调节等重要的生理及生化功能,介导上皮细胞之间的粘附、相互作用以及识别的功能。 甲胎蛋白(AFP):1963年前苏联Ablelev在肝癌移植小鼠中发现了AFP,次年他的同胞Tatarinov在原发性肝癌患者血中发现AFP升高。 1970年以后晚期hcc * 见于正常成年个体的肝细胞被破坏后的再生(急、慢性肝炎,重症肝炎恢复期,肝硬化)、 * - Expression of EGFR has been observed in a variety of human tumors, both in vitro and in vivo.[1-15] The increased level of expression found in many tumor types and its consequences on tumor growth provide the rationale for targeting the EGFR in cancer therapy. - The level of EGFR expression varies widely with tumor type. In certain tumor types, EGFR expression is very common. - Variation in EGFR expression observed within studies of a given tumor type could be due in part to a lack of consistency in detection methods, inherent biological differences between tumors, and/or stage of disease. - High levels of EGFR activity can occur as a result of elevated production of receptor ligands (EGF, TGF-alpha). - EGFR expression has been correlated with increased resistance to certain chemotherapeutic agents and radiotherapy. - Substantial evidence exists for increased EGFR expression in multiple tumor types. 1.
