Tumor metastasis is the leading cause of death for gastric cancer.Metastasis is the main reason for the failure of clinical treatment for gastric cancer.In order to find metastasis-related genes and abnormal signal transduction pathway of high-invasive gastric cancer,samples of gastric cancer with liver metastasis were collected for microarray detection; up-regulated or down-regulated genes in all three cases were simultaneously screened out.Subsequently,from the preliminary screened genes,molecular pathways possibly impacting liver metastasis from gastric cancer were investigated by the Gene Cluster with Literature Profiles(GenCLip)analysis software.Many biological effects including apoptosis have been validated.Functional analysis of differentially expressed genes revealed that a variety of biological pathways,such as blood circulation and gas exchange,vasodilation and vasoconstriction regulation,and immune defense,could be significantly activated.Besides,gene sequences,specific

杂种优势利用是培育高产优质油菜新品种的重要途径,9012AB类型的隐性核不育系统因具有临保系,可以繁殖100%的不育系而成为最具有利用潜力的授粉控制系统之一。在该不育系统的利用中,临保系的选育是关键。但由于该遗传模式较为复杂,通过传统的育种方法选育临保系费时费工且效率较低,而利用分子标记辅助选择和小孢子培养技术相结合的策略可以快速选育出基因型纯合且性状稳定的临保系。本研究以几个综合性状较好的春油菜
