The promise of precision medicine is conditioned on knowing the vulnerabilities of a given tumor. The Witkiewicz-Knudsen Lab has been active through the years in defining the genetic makeup of tumors, building patient-derived models to test hypotheses and using sophisticated approaches to interrogate clinical tissue specimens.

Imaging the response to CDK4/6 inhibitors in clinical specimens: Multispectral immunofluorescence with a panel of cell cycle markers was deployed on paired pre-treatment and treated with CDK4/6-inhibitor based therapy. These data illustrate the profound effects on cell cycle that are observed with treatment with this therapeutic regimen. 

We are currently developing new approaches to coordinately investigate features of signaling and cell cycle coordination in the tumor, while defining features of the microenvironment. Parallel studies are using computational approaches to direct the use of CDK inhibitors and other therapeutic modalities moving forward.
