Scientific Interests:

The goal of our research program is to exploit the emerging information on dysregulated signaling circuitries and individual genomic and molecular alterations to identify new therapeutic options to prevent and treat cancer. Our laboratory has focused on the study of growth-promoting signal transduction pathways, the nature of the dysregulated signaling networks in cancer, and on the use of genomic, proteomic, and system biology approaches to study tumor progression and immune escape, aimed at identifying new cancer therapies. 

Specifically, we have shown that human and virally-encoded G proteins and G protein coupled receptors (GPCRs) can display potent oncogenic activity, and that many human malignancies harbor mutations in this receptor family and their linked G proteins. We have studied the tumorigenic activity of G proteins and GPCRs to dissect the signaling circuities regulating normal and aberrant cell proliferation, cancer progression, tumor-induced angiogenesis, and metastasis. We are now investigating 1) the mechanisms by which genetic mutations in Gαq proteins initiate uveal and cutaneous melanoma, with emphasis on the regulation of the Hippo pathway; 2) the role of Gαs and its target, PKA, in cancer; and 3) how mutations, overexpression, and oncocrine activation of GPCRs contribute to tumor progression, immune evasion, and therapy resistance. 

In parallel, 4) we are exploring the role of the PI3K/mTOR signaling circuitry in cancers of the oral cavity, a disease that results in 300,000 deaths each year worldwide. Based on our prior studies, and emerging results from our recently completed multi-institutional clinical trial targeting mTOR in oral cancer, we are now investigating the effectiveness and mechanism of action of direct and indirect PI3K/mTOR inhibitors for oral cancer prevention and treatment, as single agents and as part of novel multimodal immunotherapy approaches.

Other relevant information:

Born and raised in Argentina, Dr. Gutkind have shared this passion for biomedical research with many students and trainees from underrepresented groups, learning from their cultural and ethnic diversity and unique personal and professional backgrounds and perspectives. For example, early in his career as a laboratory head at the NIH, he was awarded the 1999 EEO Special Achievement Award, NIH, for training post back fellows from historically African-American educational institutions. He also delivered multiple keynote lectures at the NIH and other institutions recognizing Hispanic contributions to research in the United States, as well as his leadership role in training Hispanic research fellows. In addition, Dr. Gutkind has been recently elected to the National Academy of Medicine, reflecting his team’s passion for translating their discoveries into new treatment options for diseases that have strong health disparities impact.
