Objective(s):  The role of the Apoptosis repressor with caspase recruitment domain (ARC) in apoptosis and in certain hypertrophic responses has been previously investigated, but its regulation of Endothelin-1 induced cardiac hypertrophy remains unknown. The present study discusses the inhibitory role of ARC against endothelin–induced hypertrophy. Results:In present study Endothelin treated car...

BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

Reactive oxygen species have multiple effects on vascular cells. Defining the sources and the impact of the various reactive oxygen species within the vessel wall has emerged as a major area of study in vascular biology. This review will focus on recent findings related to effects of reactive oxygen species on cerebral vascular tone. Effects of superoxide radical, hydrogen peroxide, and the rea...

ROS (reactive oxygen species) and RNS (reactive nitrogen species) are central to the innate immunity that protects us from infection, but also contribute to degenerative diseases and possibly aging. However, ROS and RNS are increasingly recognized to contribute to physiological signalling. This review briefly describes the main interactions between ROS and RNS and shows how their origins, chemi...

The production of reactive oxygen species (ROS), via consumption of oxygen in a so-called oxidative burst, is one of the earliest cellular responses following successful pathogen recognition. Apoplastic generation of superoxide (O2 ), or its dismutation product hydrogen peroxide (H2O2), has been documented following recognition of a variety of pathogens (Doke, 1983; Auh and Murphy, 1995; Grant ...
