流行病学和病理学研究表明胃黏膜肠上皮化生与胃癌的发展密切相关。但是由于实验条件和相关技术的限制,人们对细胞病变过程中的分子事件还了解甚少,特别是病变演化过程中有哪些重要基因参与、这些基因的改变与临床生物学行为的关系等是肿瘤研究领域的重要科学问题。c-met基因编 Epidemiological and pathological studies have shown that gastric mucosal intestinal metaplasia is closely related to the development of gastric cancer. However, due to the limitations of experimental conditions and related technologies, little is known about the molecular events in the cytopathic process, especially the important gene involved in the evolution of the lesion. The relationship between the changes of these genes and the clinical biological behavior is tumor Important scientific issues in the field of research. c-met gene series
