Erectile dysfunction (ED) affected the lives of more than 300 million men worldwide. Erectile dysfunction drugs (EDD), known as phosphodiesterase inhibitors (PDEIs), have been used for treatment of ED. It has been shown that oxidative stress plays an important role in the progression of erectile dysfunction. Oxidative stress can be alleviated or decreased by antioxidant enzymes. Therefore, the ...
This article is a report on a symposium held at the March 1997 meeting of the American Society for Pharmacology and Experimental Therapeutics in San Diego. Current developments in the heterologous expression of cytochrome P450, NADPH-cytochrome P450 reductase, glutathione transferase, and UDP-glucuronosyltransferase enzymes are described. Systems include bacteria, insect cells, and transient an...
The response of plants to the peroxidizing herbicide oxyfluorfen was investigated. The action of this p-nitrodiphenyl ether is based on inhibition of plastidic protoporphyrinogen oxidase, which leads to accumulation of protoporphyrin IX in the cytosol yielding reactive oxygen species by light activation. The induction of activities of antioxidative enzymes was followed in Nicotiana tabacum plan...
Introduction The flavoprotein disulphide oxidoreductases constitute a growing family of homologous dimeric enzymes, with an important and diverse range of functions in vivo. Among its members are dihydrolipoyl dehydrogenase, glutathione reductase, mercuric reductase, thioredoxin reductase, trypanothione reductase and a related enzyme, NADPH peroxidase (for recent reviews of their structures and...
The present study investigates the roles of exogenous proline (Pro, 5 mM) and glycine betaine (GB, 5 mM) in improving salt stress tolerance in salt sensitive (BRRI dhan49) and salt tolerant (BRRI dhan54) rice (Oryza sativa L.) varieties. Salt stresses (150 and 300 mM NaCl for 48 h) significantly reduced leaf relative water (RWC) and chlorophyll (chl) content and increased endogenous Pro and inc...
