Question: Translation Of Graph Theory Into Experimental Verification

Hi BioStars,

Graph theoretical approaches are becoming very common in bioinformatics. Have you ever come across a group that generated a network to construct hypotheses, and then used that information to design follow-up experiments that discovered something new and important?

I am interested to see an example of this translation, regardless of the network generation technique (what represents nodes - genes, etc - and edges), the experimental technique, the organism of study, etc.

Thank you!!

The Eichler lab created a network of interacting proteins more likely to harbor de novo [mutations in autism probands:]. They then performed follow-up sequencing to confirm that these genes are more likely to be mutated. I did not see a reference for the follow-up study (it may be unpublished), but [this review:] briefly describes the follow-up (page 100).

I am not sure that their follow-up discovered something 'new and important' but it certainly confirmed that their protein network contained many genes likely to have de novo mutations in sporadic autism populations.

Here are two such examples from our lab, where networks are being inferred from the data and then they are being used for further prediction followed by experimental follow-up:

  1. Perturbation Biology: Inferring Signaling Networks in Cellular Systems
  2. Drug Synergy Screen and Network Modeling in Dedifferentiated Liposarcoma Identifies CDK4 and IGF1R as Synergistic Drug Targets
