Reactive Oxygen Species Induce Procalcitonin Expression in Trigeminal Ganglia Glia

Reactive oxygen species induce chondrocyte hypertrophy in endochondral ossification

Chondrocyte hypertrophy during endochondral ossification is a well-controlled process in which proliferating chondrocytes stop proliferating and differentiate into hypertrophic chondrocytes, which then undergo apoptosis. Chondrocyte hypertrophy induces angiogenesis and mineralization. This step is crucial for the longitudinal growth and development of long bones, but what triggers the process i...

O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

Reactive oxygen species induce Cox-2 expression via TAK1 activation in synovial fibroblast cells

Oxidative stress within the arthritis joint has been indicated to be involved in generating mediators for tissue degeneration and inflammation. COX-2 is a mediator in inflammatory action, pain and some catabolic reactions in inflamed tissues. Here, we demonstrated a direct relationship between oxidative stress and Cox-2 expression in the bovine synovial fibroblasts. Furthermore, we elucidated a...

Reactive oxygen species induce apoptosis of vascular smooth muscle cell.

Apoptosis of vascular smooth muscle cell (VSMC) plays an important role in the genesis of atherosclerosis and restenosis. In order to investigate the role of reactive oxygen species in the induction of VSMC apoptosis, rat VSMCs were treated with glucose oxidase/glucose (GO/G) or diethylmaleate (DEM). The results showed that GO/G and DEM led to VSMC death. Administration of catalase, superoxide ...
