人类已逐步进入功能基因组时代。基因芯片作为近期发展起来的一项新技术 ,能够研究细胞内所有基因的表达谱 ,同时获得成千上万个基因活化的模式 ,并为研究肿瘤发生发展过程中的基因表达情况提供了强有力的工具。本文对基因芯片技术在肿瘤研究中的应用 ,包括寻找新的肿瘤相关基因、基因表达谱研究、基因功能研究、肿瘤分子病理分型及诊断芯片等方面进行了探讨。 Humanity has gradually entered the era of functional genomes. As a recent development of the new technology, the gene chip can study the expression profile of all genes in cells, and at the same time obtain thousands of gene activation patterns, and provide a powerful tool for studying gene expression during the development of tumors. Tool of. This article discusses the application of gene chip technology in tumor research, including the search for new tumor-related genes, gene expression profiling, gene function research, tumor molecular pathological typing, and diagnostic chips.
