| Abstract: | Microarray techniques have been widely used to monitor gene expression in many areas of biomedi？cal research. Such as the diagnosis and classification, prediction and treatment of tumor, understanding the mecha？nism of tumor, biological pathways and gene networks. Statistical methods are vital for these scientific endeavors.In this article we reviewed recent developments of statistical methods for analyzing data from microarray experiments. Mainly described the standardization of microarray data, statistical tests of differentially expressed genes, and the application of the microarray technology in tumor treatment. Emphasis introduced time series microarray data analy？sis method and the latest development in the study of gene regulatory networks in tumor. |
