Title Mechanisms of Polyploidy and Aneuploidy in the Liver
Description: Nearly 25 million Americans are affected by liver dysfunction, and liver diseases are the 10th leading cause of death in the US. There is a clear and urgent need for developing new alternatives to whole organ replacement. A better understanding of liver biology is required to improve existing approaches and to innovate therapies for the treatment of liver diseases, including viral hepatitis and steatohepatitis. Hepatocytes, the primary functional cell type in the liver, display a range of chromosomal diversity resulting from prevalent physiological polyploidy (>90% in mice and 50% in humans) and aneuploidy (60% in mice and 30-90% in humans). In eukaryotic organisms, cells usually contain a diploid genome comprised of pairs of homologous chromosomes. Polyploidy refers to gains in entire sets of chromosomes, and aneuploidy refers to gains and losses of individual chromosomes. The roles of hepatic polyploidy and aneuploidy represent a major gap in our current understanding of liver biology. We recently found that aneuploidy enhances the regenerative capacity of the mouse liver. In response to Tyrosinemia-induced injury, that is normally toxic to the liver, we identified a subset of aneuploid hepatocytes that was resistant to the disease. The data suggest that aneuploid hepatocytes are endowed with enhanced capacity for adaptation and regeneration. Our central hypothesis is that aneuploidy functions as an adaptive mechanism in response to hepatic injury. The goals of this application are to identify mechanisms regulating hepatic aneuploidy/polyploidy and to unravel how aneuploidy affects liver function. To investigate these questions, we propose in Specific Aim 1 to determine whether polyploid hepatocytes are necessary for development of aneuploid livers. Experiments will characterize hepatic cell divisions, karyotypes and stress response in E2f7/E2f8 knockout mice, which have normal liver function but are depleted of polyploid hepatocytes. In Specific Aim 2, we will dissect the role of a novel regulator of hepatic polyploidy, recently identified in our laboratory, microRNA-122 (miR-122). Experiments will determine how miR-122 alters ploidy and aneuploidy throughout life. We will also identify cellular and molecular mechanisms by which miR-122 regulates hepatic ploidy. Finally, in Specific Aim 3, we will determine how random karyotypes (in aneuploid hepatocytes) affect function in the liver. We will utilize a novel xenotransplantation model to examine clonal nodules of regenerating human hepatocytes. Experiments will measure aneuploidy and determine gene expression profiles in these nodules. Together, these studies will define the extent to which aneuploidy affects liver repair/regeneration as well as the molecular mechanisms that control this process. Understanding how aneuploid hepatocytes arise and function will provide new and crucial insights into liver homeostasis, diseases and treatments.
Several years ago, McGowan Institute for Regenerative Medicine faculty member Eric Beckman, PhD, George M. Bevier Professor of Engineering in the University of Pittsburgh Department of Chemical and Petroleum Engineering, and Michael Buckley, MD, oral and maxillofacial surgeon, invented a novel medical adhesive technology. The new adhesive—now known as TissuGlu®—was designed to meet a market demand for a strong, safe tissue adhesive to improve the wound closure process. The product positions tissues for optimal healing while minimizing fluid accumulation. To move the University of Pittsburgh-developed technology towards clinical use, Cohera Medical, Inc. was formed, and the intellectual property was licensed by the University to Cohera.
New Processes Could Provide Personalized Pain Treatment
As reported by Karen Ferrick-Roman, Duquesne University Fall 2014 Magazine, pain costs Americans up to $635 billion each year for medical treatment and in lost productivity, says the Institute of Medicine of the National Academies. That hefty price tag is equivalent to the first 10 years of spending for homeland security, illustrating a nationwide problem of giant proportions. Today, an estimated 116 million Americans live with chronic pain.
Learning a new skill is easier when it is related to ability that we already possess. For example, a trained pianist might learn a new melody more easily than learning how to hit a tennis serve. Neural engineers from the Center for the Neural Basis of Cognition (CNBC)—a joint program between the University of Pittsburgh and Carnegie Mellon University—have discovered a fundamental constraint in the brain that may explain why this happens.  McGowan Institute for Regenerative Medicine faculty member Elizabeth Tyler-Kabara, MD, PhD, an assistant professor in the Departments of Neurological Surgery, Bioengineering, and Physical Medicine and Rehabilitation at the University of Pittsburgh, the director of the Spasticity and Movement Disorder Program at Children’s Hospital of Pittsburgh of UPMC, and the director of the Surgical Epilepsy Program in the Department of Neurological Surgery, is a co-author of the study.
