Professor of Chemical and Systems Biology, Emeritus
Current Research and Scholarly InterestsInsulin is one of the primary regulators of rapid anabolic responses in the body. Defects in the synthesis and/or ability of cells to respond to insulin results in the condition known as diabetes mellitus. To better design methods of treatment for this disorder, we have been focusing our research on how insulin elicits its various biological responses.

Theodore Roth
Assistant Professor of Pathology
Current Research and Scholarly InterestsThe Roth Lab develops, applies, and translates scalable genetic manipulation technologies in primary human cells and complex in vivo tissue environments. Working with students, trainees, and staff with backgrounds across bioengineering, genetics, immunology, oncology, and pathology, the lab has developed CRISPR-All, a unified genetic perturbation language able to arbitrarily and combinatorially examine genetic perturbations across perturbation type and scale in primary human cells. Ongoing applications of CRISPR-All in the lab have revealed surprising capacities to synthetically engineer human cells beyond evolved cellular states. These new capacities to perturb human cell’s genetics beyond their evolved functionality drives ongoing work to understand the biology and therapeutic potential of synthetic cell state engineering - in essence learning how to build new human genes tailor made for a specific cell and specific environment to drive previously inaccessible therapeutic cellular functions.

Florentine Rutaganira
Assistant Professor of Biochemistry and of Developmental Biology
Current Research and Scholarly InterestsWe use chemical tools to decipher the roles of key signaling networks in choanoflagellates, single-celled organisms that are the closest living relatives of animals. Choanoflagellates produce molecular signals essential for intercellular communication in animals and the presence of these molecules in choanoflagellates suggests that signaling components needed to communicate between cells is evolutionarily ancient. We aim to uncover new understanding of animal development, physiology and disease.

Raya Saab
Lindhard Family Professor of Pediatric Cancer Biology
BioI am a pediatric oncologist, and I primarily treat children who are diagnosed with soft tissue sarcomas including rhabdomyosarcoma, and children diagnosed with the eye tumor retinoblastoma, as well as children with other solid tumors.
I have two very different areas of primary research interest, both of which I pursue with passion. One focuses on global oncology, including clinical and research resource capacity building towards effective treatment and improving outcomes of children with cancer worldwide. I work with collaborators across the globe towards a common goal of improving access to diagnostic and clinical care, training of multidisciplinary teams, and building clinical resources and research capacity to develop context-informed approaches to improving cancer care and achieving better outcomes for children diagnosed with cancer irrespective of where they happen to live.
My parallel research interest, which is the focus of my laboratory, is understanding oncogenic signaling in pediatric soft tissue sarcomas, in an effort to clarify the driving biology and determinants of metastatic disease, to uncover novel targets for more effective treatment. We use preclinical in vitro and in vivo models, including murine and human cell lines, and mouse models of cancer. We have recently uncovered a paracrine role for rhabdomyosarcoma-secreted exosomes in impacting biology of stromal cells. Rhabdomyosarcoma-derived exosomes carry specific miRNA cargo that imparts an invasive and migratory phenotype on normal recipient fibroblasts, and proteomic analysis revealed specific and unique pathways relevant to the two different molecular rhabdomyosarcoma subtypes that are driven by distinct oncogenic pathways. We identified that the driver oncogene in fusion-positive rhabdomyosarcoma, PAX3-FOXO1, modulates exosome cargo to promote invasion, migration, and angiogenic properties, and identified specific microRNA and protein cargo acting as effectors of PAX3-FOXO1 exosome-mediated signaling, including modulation of oxidative stress response and cell survival signaling. Our ongoing work is focused on interrogating specific paracrine signaling pathways and molecular mechanisms of metastatic disease progression in rhabdomyosarcoma, for potential therapeutic targeting. -
