Senescence is a genetically regulated oxidative process that involves a general degradation of cellular structures and enzymes and the mobilization of the products of degradation to other parts of the plant. The cDNA-AFLP (cDNA-Amplified Fragment Length Polymorphism) analysis has been used under stringent PCR conditions afforded by ligation of adapters to restriction fragments, and the use of s...

Phenylalanine amonia-lyase (PAL) is one of the most important enzymes that plays a key role in regulationof phenylpropanoid production in plants. It catalyzes the first step of the phenylpropanoid pathway in whichL-phenylalanine is deaminated to trans-cinnamic acid. This step is significant for metabolic engineering andhyper-expression of the major phenylpropanoid, methyl chav...

Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

Drought stress is one of the serious problems that restricted agronomic plant production worldwide. In molecular level, the harmful effect of drought stress is mostly caused by producing of large amount of reactive oxygen species (ROS). Catalase and Metallothionein genes have a crucial role to mope the hydrogen peroxide (H2O2) resulting reducing oxidative damage. In this research the gene expre...

background & aims of the study: oxidative stress increases platelet-derived growth factor (pdgf) gene expression in endothelial cells that contributes to vascular dysfunction and atherosclerosis. oxidative stress generates by dys-regulated redox balance between ros producing systems and antioxidant systems. also, curcumin (cur) as a main part of turmeric has anti- inflammatory, antioxidant, ant...
