  • Our lab is interested in determining the molecular mechanisms involved in neurodegeneration associated with Alzheimer's disease (AD). Specifically, we are examining the role of cell cycle regulatory proteins and inflammatory proteins in neuritic plaque and neurofibrillary tangle formation. Experimental systems include transgenic mice and in vitro cultured transformed cells and primary neurons. While aberrant cell cycle activation is a characteristic feature of cancer progression, deregulated expression of cell cycle proteins in terminally differentiated neurons leads to catastrophe. Our recent studies showed that amyloid precursor protein (APP), which is associated with Alzheimer's disease may play a role in cancer progression. We are currently performing experiments to establish a correlative link between neurodegeneration and oncogenesis.

  • Our lab studies the pathogenesis of Alzheimer's disease (AD). Specifically, we are interested in the molecular mechanisms that lead to the aberrant cell cycle that is observed in the AD brain. We have found that the amyloid precursor protein (APP), a central protein in AD, is modified and pathogenically processed in a cell-cycle specific manner. Furthermore, we have found that APP induces expression of proteins such as ras and gamma-synuclein, which are involved in cellular proliferation. The aim of my research is to elucidate the mechanisms by which APP induces the expression of these proliferation-associated proteins and determine how it leads to neurodegeneration and cognitive decline.
