Cancer, Metabolic Diseases, Obesity
 Watch Dr. Moscat describe his research
Dr. Moscat’s research group is interested in understanding the molecular and cellular signaling mechanisms that underlie the metabolic control of cancer cells. They are particularly interested in the importance and mechanisms of action of a number of key proteins in these processes, such as the atypical protein kinases (aPKCs) and their regulators, Par-4, NBR1, and p62.

Previous Findings
A key finding from our laboratory is that the genetic ablation of p62 in mice leads to obesity, suggesting a role of p62 in the control of the differentiation of fat cells (also known as adipogenesis). This implication of p62 in the control of cell differentiation is also important on its role in the control of Th2 polarization in asthma, as well as in cancer. Studies from our laboratory in lung cancer demonstrate that p62, and its partner PKCzeta, play essential roles in tumorigenesis likely through the control of cancer cell survival and metabolism.
Current Studies
Intratumoral nutrient stress has been found even in early-stage cancers, correlating with poor patient survival. Therefore, the investigation of the signaling mechanisms governing cancer cell proliferation under nutrient deprivation is of paramount importance for the identification of new and more selective therapeutic targets, and for a better understanding of the role of the tumor microenvironment in the response of cancer cells to nutrient shortage. We previously showed that the loss of PKCζ induced tumorigenesis in several endogenous mouse cancer models including lung (Ras), prostate (PTEN) and intestine (APC). Our more immediate goals are to explore a novel role for PKCζ and other components of its signaling cascade and family, such as PKCλ/ι, as a tumor suppressor that acts by controlling the interplay between tumor cells and the inflammatory microenvironment milieu. The long-term goal of our laboratory is to identify novel signaling networks that influence cell metabolism and allow cancer cells to proliferate under inflammatory and nutrient-scarce microenviromental conditions.
About Jorge Moscat
Experience
Dr. Moscat earned a bachelor’s degree in chemistry and a doctorate in biochemistry/molecular biology at the Universidad Complutense in Madrid, Spain. He completed postgraduate studies with fellowships of the Spanish Education and Science Ministry and Juan March Foundation in Madrid and at the NIH. Dr. Moscat joined the University of Cincinnati in 2006 from the Center of Molecular Biology of the Spanish National Research Council in Madrid, where he conducted cancer cell biology research, focusing primarily on signaling pathways in cancer, obesity and inflammation. In 2008, he became professor and chairman of the Department of Cancer and Cell Biology at the University of Cincinnati College of Medicine and associate director of basic science for the Cincinnati Cancer Consortium. Dr. Moscat joined the Sanford-Burnham faculty in 2011.
