Identification of oxidative stress-regulated genes in rat aortic smooth muscle cells by suppression subtractive hybridization
AbstractA suppression subtractive hybridization technique was used to identify reactive oxygen species (ROS)-regulated genes in rat vascular smooth muscle cells. Three genes out of 89 clones, identified as fibronectin, p105 coactivator and ECA39, showed increased expression after treatment with H2O2. The mRNA expressions of these three genes were induced in a time- and dose-dependent manner, independent of protein kinase C activation. Immunohistochemical staining showed that the p105 coactivator expression was markedly induced in the neointima of balloon-injured rat carotid arteries. These results suggest that ROS may play an important role in the development of atherosclerosis by regulating the gene expressions we identified in this study

Qualitative and Quantitative Comparisons of Texture Characteristics between Broiler and <i>Jidori-niku</i>, Japanese Indigenous Chicken Meat, Assessed by a Trained Panel
Qualitative and Quantitative Comparisons of Texture Characteristics between Broiler and Jidori-niku, Japanese Indigenous Chicken Meat, Assessed by a Trained Panel
The texture of jidori-niku (Japanese indigenous native chicken meat) was characterized and compared with those of Chunky broiler chicken meat. Experiment 1: A qualitative sensory test using jidori-niku and broiler breast (pectoralis major, PM), thigh (biceps femoris, BF) and sasami (deep pectoral) meat cooked to the end-point temperature 75°C by steam-heating was administered to a trained sensory panel (nïŒ16-17) for the selection of descriptive texture items from ISO5492 texture words. By the correspondence analysis, the characteristics of âchewiness,â âhardnessâ and âspringinessâ were found to be different between jidori-niku and broiler: they likely characterize jidori-niku texture. Experiment 2: Texture characteristics in the three above-mentioned muscles in jidori-niku and broiler were compared quantitatively using the three above-mentioned texture items by the trained sensory panel. Sensory chewiness and hardness were the highest in the broiler PM and second highest in the jidori-niku BF, whereas sensory springiness was the highest in the jidori-niku BF. These results suggest that jidori-niku-like texture was characterized as a springy texture as compared to broiler meat
