Reliable and efficient detection of DNA damage constitutes a vital capability of human cells to maintain genome stability. Following DNA damage, the histone variant H2AX becomes rapidly phosphorylated by the DNA damage response kinases DNA-PKcs and ATM. H2AX phosphorylation plays a central role in signal amplification leading to chromatin remodeling and DNA repair initiation. The contribution o...
Some engineered nanomaterials (ENMs) may have the potential to cause damage to the genetic material in living systems. The mechanistic machinery functioning at the cellular/molecular level, in the form of DNA repair processes, has evolved to help circumvent DNA damage caused by exposure to a variety of foreign substances. Recent studies have contributed to our understanding of the various DNA d...
this study aimed to investigate effects of malathion on dna breakage in the liver and gill of rainbow trout (oncorhynchus mykiss) in the laboratory condition. the experiment was performed with four concentrations of malathion, i.e. 0 (control), 0.025, 0.05 and 0.075 mg l‑1 and three replicate for nine days. the liver and gill were sampled on the first, fifth and ninth days after the start of th...
