Research Interests
Quantitative Oncology Research
My interest is in developing and testing quantitative models of oncogenic pathway activation. This extends previous work where I demonstrated that ectopic Myc and Ras activity in cell culture generate transcriptional changes that allow one to model their activity in in vivo. Gene expression-based models accurately recapitulate the activity of Myc-activated and Ras-activated pathways in the cell cycle, demonstrating kinetics that match their known biochemical activity and, more importantly, accurately predict the activity of Myc and Ras in tumor tissues from MMTV transgenic mouse models.
Currently, there are two broad thrusts to the work we are doing:
A. Latent Factor Models of Cancer Signaling
Extending on work by colleagues Carvalho, Lucas, West and Chang in the Department of Statisical Sciences and the IGSP, I am interested in using latent factors, particularly Bayesian factor regression models (BFRM, see Carvalho, JASA, 2008) to decompose oncogenic signaling pathways into signaling components. This extends from my previous work, but uses new techniques that reflect our intuition that the entirety of a signaling cascade is not inflexibly stereotyped irregardless of tissue type or context. There are obviously numerous strategies for tackling this problem. We pursue a paradigm that in vitro perturbations of oncogenic activity elicit patterns that can be traced out in vivo. Further, preclinical in vivo models provide an opportunity to refine these in vitro building blocks.
To test whether these latent factors have the potential to serve as phenotypes, along the lines of Bild, et al. (Nature, 2006), we think of response to targeted cancer therapeutics as a quantitative phenotype. If a targeted agent can attenuate or alter known signaling pathways, then the configuration of a tumor’s molecular machinery should reflect this fact. Our goal is to confirm this concept in vitro and ramp up to in vivo mouse xenograft models, and hopefully, beyond.
A consequence of factor models of oncogenic signaling is that it is trivial to develop models that allow components of multiple signaling pathways to become interleaved depending on the context. Because of this a parallel goal is to create a ‘library’ of pathway factors that can be heterogeneously employed to answer our questions.
B. QUADRA-Genomic Factor
If we want to build a resource consisting of informative factors for elucidating cancer signaling it is important that it is in a framework that is intelligible to (1) ourselves, (2) our colleagues, (3) the scientific community. We therefore are building a resource called QUADRA-Genomic Factor (Quality-Assured Data Repository and Analysis-Geomic Factor) that rigorously version controls our work from inception to publication, providing a transparent, auditable, and reproducible foundation from which to work. Such tools are actually not new: software developers have been using versioning systems for years. Being able to rewind your analysis, or branch out new ideas without overwriting your previous work, or merge collaborative projects are all things that programmers do everyday. We should do the same, both to make it easier on ourselves and for others. The aim is to version all our analyses, all our custom functions, and our libraries of factors. In combination with this, we are building resources to tag genomic data with metadata that make it simple to perform programmatic reconciliations that minimize the chance that errors do get propagated throughout a complex genomic analysis.
