These efforts are actually more related than you might think. One problem with the current state of molecular biology is that mechanisms are represented as graphs comprised of nodes (genes and molecules) and activities (inhibition, activation, catalysis, etc.); however, these graphs are generally representations at whole-genome scale. Within each single cell, only a subset of the genome is expressed, which greatly limits the size and complexity of the graph in actual incarnations within cells and therefore simplifies the problem.
