Summary
The aim of this project is to elucidate the mechanisms behind the intracellular regulation of nitrogen monoxide (NO) levels, which has broad implications for understanding NO activity in many processes which have major vital health implications, including the cytotoxic of macrophages and the control of blood pressure.
The Evaluation Of Gamma-glutamylcyclotransferase As A Novel Target For Cancer Therapy And Diagnosis

Summary
Gamma glutamylcyclotransferase (GGCT) plays a pivotal role in regulating the synthesis of glutathione, a compound that is essential for life and regulates many intracellular processes. Several recent studies have shown that GGCT is highly expressed in cancer cells . This study will determine if GGCT is a target for cancer chemotherapy or if it can be used for cancer diagnosis. This study may also provide a new treatment for patients with glutathione synthetase deficiency.
Prevention Of Drug Toxicities With Dichloroacetic Acid - The Implications For Cancer Chemotherapy

Summary
Many valuable cancer drugs have limited clinical use because of their toxic side effects. Our experiments with a new anti cancer drug called dichloroacetic acid (DCA) will determine if it can reduce the toxic effects of Cisplatin on the kidney and the effects of Doxorubicin on the heart.
Glutathione Transferase Deficient Mice To Probe For Adverse Drug Reactions

Summary
A family of enzymes called glutathione transferases (GST) that metabolize foreign chemicals and therapeutic drugs have been shown to be a significant cause of drug resistance in cancer chemotherapy. It has been suggested that inhibitors of GSTs could be used in cancer treatment to counter drug resistance or to slow the metabolism and enhance the activity of some drugs. Some GSTs carryout important enzymatic reactions with endogenous substrates and others have important non-enzymatic functions su ....A family of enzymes called glutathione transferases (GST) that metabolize foreign chemicals and therapeutic drugs have been shown to be a significant cause of drug resistance in cancer chemotherapy. It has been suggested that inhibitors of GSTs could be used in cancer treatment to counter drug resistance or to slow the metabolism and enhance the activity of some drugs. Some GSTs carryout important enzymatic reactions with endogenous substrates and others have important non-enzymatic functions such as the regulation of signaling pathways within cells and the modulation of calcium ion channels that are involved in muscle contractions. The generic inhibition of all GSTs could therefore have significant adverse physiological effects. We propose to make mice deficient in specific GSTs and to study their physiological responses. The results of these studies will indicate which GSTs can be safely inhibited without the risk of deleterious side effects. These studies are important because adverse reactions to therapeutic drugs are a significant cause of hospital admissions and death.Read moreRead less
