| 摘要 |
The present invention provides methods for profiling, in a global manner, the activity of gene regulatory elements in cells, including eukaryotic and prokaryotic cells. The methods involve analysis of regulatory element complexes formed under cell-free conditions or within cells (sometimes called "in vivo"). In accordance with the invention, cells can be in any state of metabolism, resting, growing, normal, mutant, diseased or differentiating. The gene regulatory element activity profiles generated for the cells in different cell populations are compared to determine differences in gene regulatory activity and overall gene expression between or among different types or states of cells.
