1. Structural Studies of Human 5'-Nucleotidases
Abstract : 5’-Nucleotidases (5’NTs) are catabolic enzymes of the nucleotide metabolism. They catalyze dephosphorylation of deoxyribo- and ribonucleoside monophosphates and constitute an important control point in the regulation of intracellular nucleotide pools for the maintenance of correct DNA and RNA synthesis.

2. The role of 5'-nucleotidases and deoxynucleoside kinases in responses to nucleoside analogues
Abstract : The efficacy of nucleoside analogues (NAs) in treating several hematological malignancies, solid tumors and viral infections is limited primarily by side-effects and the development of drug resistance. The aims of the present thesis were to elucidate mechanism(s) involved in tissue-specific toxicity associated with NA therapy, as well as the mechanisms underlying resistance to these drugs.

3. Molecular regulators of glucose and lipid metabolism in skeletal muscle
Abstract : Skeletal muscle is a primary site of insulin action and insulin-stimulated glucose transport and occupies a center stage in maintaining whole body glucose and lipid homeostasis. Another key feature of a healthy skeletal muscle is its ability to switch between utilization of lipids and glucose as fuel in response to feeding or fasting respectively. READ MORE

4. Studies of overcoming acquired resistance : molecular mechanisms and development of novel drugs
Abstract : Chemotherapeutic agents have become widely applied for treatment of various types of malignancies. Drug resistance unfortunately remains as a major obstacle for the effectiveness of chemotherapy. Cancer drug resistance includes two broad categories: intrinsic and acquired. READ MORE
