Integrated Analysis Identifies Interaction Patterns between Small Molecules and Pathways

Abstract EN

Previous studies have indicated that the downstream proteins in a key pathway can be potential drug targets and that the pathway can play an important role in the action of drugs.

So pathways could be considered as targets of small molecules.

A link map between small molecules and pathways was constructed using gene expression profile, pathways, and gene expression of cancer cell line intervened by small molecules and then we analysed the topological characteristics of the link map.

Three link patterns were identified based on different drug discovery implications for breast, liver, and lung cancer.

Furthermore, molecules that significantly targeted the same pathways tended to treat the same diseases.

These results can provide a valuable reference for identifying drug candidates and targets in molecularly targeted therapy.
