Microarray, SAGE and their applications to cardiovascular diseases Ye SQ; Lavoie T; Usher DC; Zhang LQCell Res 2002[Jun]; 12 (2): 105-15The wealth of DNA data generated by the human genome project coupling with recently invented high-throughput gene expression profiling techniques has dramatically sped up the process for biomedical researchers on elucidating the role of genes in human diseases. One powerful method to reveal insight into gene functions is the systematic analysis of gene expression. Two popular high-throughput gene expression technologies, microarray and Serial Analysis of Gene Expression (SAGE) are capable of producing large amounts of gene expression data with the potential of providing novel insights into fundamental disease processes, especially complex syndromes such as cardiovascular disease, whose etiologies are due to multiple genetic factors and their interplay with the environment. Microarray and SAGE have already been used to examine gene expression patterns of cell-culture, animal and human tissues models of cardiovascular diseases. In this review, we will first give a brief introduction of microarray and SAGE technologies and point out their limitations. We will then discuss the major discoveries and the new biological insights that have emerged from their applications to cardiovascular diseases. Finally we will touch upon potential challenges and future developments in this area.|*Gene Expression[MESH]|Cardiovascular Diseases/diagnosis/*genetics/*metabolism[MESH]|DNA, Complementary/metabolism[MESH]|Humans[MESH]|Oligonucleotide Array Sequence Analysis/instrumentation/*methods[MESH] |
