Born in the remote wilds of the Carpathian Mountains in Ukraine, Dr. Slavko Komarnytsky is the Assistant Professor of Pharmacogenomics at the Plants for Human Health Institute, N.C. State University, and Director of the Life Habit Center for Biodiscovery.

Komarnytsky received a B.S. in biology and M.S. in cell biology from Kyiv Shevchenko University in 1998. He earned his Ph.D. in cell and molecular plant biology in 2004 and held research appointments in metabolism and nutrition at Rutgers University prior to joining the food science faculty at N.C. State University in 2011.

His primary scientific interests have been in how dietary bioactive components prevent chronic metabolic diseases and inflammation, with a specific emphasis on the pathological mechanisms of insulin resistance and muscle loss. His scholarly work has set trends in biodiscovery from natural sources and engagement of students and ethnic communities in global health research. He has authored over 40 major scientific publications and gained broad support from government agencies and industry sponsors.

Within this theme, three major initiatives can be used to describe his work:

  • Using state of the art applications of pharmacogenomics, nutrigenomic, and bioenergetics technologies to enhance understanding the pathogenesis of metabolic disorders by identifying pathways important in progression of diabetes, obesity and inflammation;
  • Collaborating with scientists from various disciplines to access efficacy of botanicals and natural products to restore metabolic balance within liver, muscle and adipose tissues; and
  • Supporting education and development of students and scholars, including those located in the developing countries, through biodiscovery from microbial resources, microbial diversity and impact it may have on the safety and health of water users.

Projects

  • Molecular controls linking inflammation to diabetes. We are dissecting the signaling pathways and transcriptional mechanisms that mediate chronic inflammation and associated risk of diabetes. This allows us to define the mechanisms of action of bioactive small molecules to alleviate insulin resistance and dyslipidemia through analyses of target genes, protein-protein interactions, and preclinical studies in animal models.
  • Botanicals in muscle growth and disease. We have identified several small molecules that modulate signaling pathways and transcription factors involved in muscle growth and remodeling during disease. We are currently pursuing a variety of strategies to manipulate these pathways and to uncover additional regulators in muscle cells that enhance muscle strength, endurance, and physical performance.
  • Phenotypical screening in cell culture. We lead discovery of novel bioactives and understanding gene function within the context of energy metabolism in conventional animal and human cell cultures, 3D cell cultures, and stem cells with potential applications for pharmaceutical, food, and cosmetics industries.
  • Epigenetic control of silent metabolic pathways. We are exploring microbes of diverse habitats and unique environments for discovery of novel metabolites. A major interest is in activation of "silent" DNA using proprietary methods to treat fungal cultures with epigenetic modulators that interfere with the formation of the heterochromatin.
