Heat shock proteins play an important role in protein homeostasis under stress conditions, and act as molecular chaperons in living organisms. Here, we investigate acute toxicity of heavy metals (Cu and Cd) and the transcriptional changes of the heat shock proteins (hsps) family genes (hsp20, hsp27, hsp70, hsp90α-1, and hsp90β) in Brachionus(More)
Polychaetes have been used as useful model organisms for environmental pollution monitoring in aquatic sediments. Here, we investigated the combined effect of copper (50, 100 and 200 μg/L) and cadmium (50 μg/L) on the expression of antioxidant enzymecoding genes (seven GST isoforms, Mn-SOD and Cu/Zn-SOD) in the marine polychaete Perinereis nuntia by(More)
Cadmium has adverse effects on aquatic organisms. Here, we measured the ROS level, total GSH contents and total GST activity after exposure to Cd. In addition, the mRNA expression of four GST isoforms was investigated in response to Cd using real-time RT-PCR in the monogonant rotifer, Brachionus koreanus. As results, intracellular ROS level was elevated,(More)
Metallothionein (MT) has been used extensively as a potential molecular biomarker to detect heavy metal pollution in aquatic organisms. In order to investigate the modulation effect of heavy metals and to establish suitable biomarkers for the monitoring of heavy metal pollution, Pelteobagrus fulvidraco metallothionein gene was characterized as the first(More)
The Kryptolebias marmoratus is unique because it is the only self-fertilizing hermaphroditic vertebrate, known to date. It primarily reproduces by internal self-fertilization in a mixed ovary/testis gonad. Here, we report on a high-quality genome assembly for the K. marmoratus South Korea (SK) strain highlighting the diversity and distribution of(More)
Heavy metals can lead to osmotic stress by disrupting the regulation of sodium ion in aquatic organisms. In this study, gene expression patterns and enzymatic activities of Na+/K+-ATPase in the monogonont rotifer, Brachionus koreanus were measured after exposure to different Cd (7.5, 15, and 30 mg/L), and Pb (0.1, 0.5, and 1.0 mg/L), respectively.
