What Do We Mean By "RAS Pathway"?

October 22, 2014, by Frank McCormick

Frank McCormick, Ph.D.

Dr. Frank McCormick directs the research efforts of the RAS Initiative at FNLCR.

Dear all,

We are planning a paper that presents a RAS-centric view of the data in TCGA.  This will be a collaboration between Gaddy Getz and colleagues at the Broad, and Bob Stephens and colleagues at the Frederick National Lab and others. The aim is to provide a synopsis of expression patterns, mutations and copy number changes, and several other parameters relevant to the RAS pathway across the  different tumor types.

As you all know, this pathway can be defined in various ways. For purposes of interrogating TCGA data we have used gene names from the Broad Tumor Portal. Some may not be familiar to you. For example, I hadn’t realized that ARHGAP35, which is mutated at quite a high frequency, is actually  p190RhoGAP, made popular by Jeff Settleman. Matt Meyerson kindly pointed this out to me.


ras pathway genes

The diagram shows 118 genes arranged in 36 groups containing one to eleven genes per group.  The proteins represented by gene names in a group are thought to carry out similar, but probably not identical, functions. Gene names separated by periods represent proteins believed to form physical complexes. At the top of the diagram "growth factors" signal through receptors and messengers to the three RAS proteins. The RAS proteins in turn signal through three alternative pathways to affect many downstream targets including TP53, RB1, and MTOR.  Arrows represent activation signals, dotted  "T" lines represent inhibitory signals. The bracket connecting KSR1 and KSR2 to the RAF, MAP2K, and MAPK genes represents a scaffolding function.

Anyway, we'd be very grateful  if you could send suggestions for genes that we missed or errors in the pathway diagram.  Any other suggestions for making this effort more useful would be welcome, particularly in the context of how to best share the TCGA data in the most useful way possible.
