Oxidative Stress – Environmental Induction

Environmental Pollution and Oxidative Stress in Fish

Living systems encounter a variety of stresses during their continuous interaction with environment. Environmentally-induced stresses frequently activate the endogenous production of reactive oxygen species (ROS), most of which are generated as side products of tissue respiration. Hence, constant exposure to stressors may enhance ROS-mediated oxidative damage. Increased number of agricultural a...

Epigenetics and environmental chemicals.

PURPOSE OF REVIEW Epigenetics investigates heritable changes in gene expression occurring without changes in DNA sequence. Several epigenetic mechanisms, including DNA methylation, histone modifications, and microRNA expression, can change genome function under exogenous influence. Here, we review current evidence indicating that epigenetic alterations mediate toxicity from environmental chemic...

Modulation of Expression of Oxidative Stress Genes of the Intertidal Copepod Tigriopus japonicus after Exposure to Environmental Chemicals

The intertidal copepod Tigriopus japonicus has been recognized as a potential model species for toxicity testing of marine pollutants. In last five years or so sequence information and expression pattern of several genes critical in detoxification, stress, growth and reproduction have been described from T. japonicus. A number of genes, especially those representing antioxidant and detoxificati...

Environmental chemicals targeting thyroid.

Thyroid hormones (THs) are required for normal brain and somatic development and for the proper regulation of physiology in both children and adults. Thyroid function is controlled by the dynamic interrelationships between the hypothalamus, the pituitary and the thyroid. These dynamic relationships maintain circulating levels of THs within a narrow range under normal conditions. Normally, there...
