Dr. Anna Gukovskaya's research has been focused for many years on pathobiology of pancreatitis and pancreatic cancer. She has become a leading expert, both nationally and internationally, on cell death pathways in pancreatic disorders. In particular, Gukovskaya's group uncovered a novel pro-survival role of reactive oxygen species in pancreatic cancer, in particular through regulation of phosphatases and kinases, such as PHLLP, Akt, and JAK2. Her most recent findings reveal that autophagy, the principal cellular degradative pathway, is impaired in pancreatitis and mediates key pathologic responses of this disease; and further, that autophagy is critical for pancreatic cancer development. Gukovskaya's current project in an NCI-funded program project grant (PPG) investigates the role of autophagy in cancer promoting effects of high-fat, high-caloric diet in oncogenic Kras driven pancreatic tumorigenesis.
