Pathway Detection from Protein Interaction Networks and Gene Expression Data Using Color-Coding Methods and A* Search Algorithms

<table>The steps of color-coding method. (a) Coloring the high-degree nodes in step  4. (b) The node with degree 1 having same color with its neighbor in step  7. (c) Randomly color the uncolored nodes in step  9. (d) Check the articulation hubs such as node <i>F</i> with different color with its neighbors in step  15.</table>
