It has received much attention from a toxicological perspective. The aim of this study was to assess the effect of Cd in the peacock blenny <i>Salaria pavo</i>, a species of the family of blennies that was used as bioindicator of water pollution. We performed a sublethal contamination of fish to 2 mg CdCl<sub>2</sub> L<sup>−1</sup> during 1, 4, 10, and 15 days. Cd accumulation was measured in gills and liver and displayed a significant increase of its concentration throughout the experiment, with slightly higher levels in the liver, except after 4 days. Partial-length cDNA of <i>mt1</i>, <i>mt2</i>, <i>mnsod</i>, <i>cuznsod</i>, <i>cat</i>, and <i>gpx</i> were characterized. Results from mRNA expression levels displayed an up-regulation of <i>mt2</i> and <i>mnsod</i>. Biomarker activities were determined in gills and liver. In gills, data displayed an inhibition of EROD and GST activities. Cd exposure significantly increased GPx activities but did not affect CAT levels throughout the experiment. No LPO induction was observed in gills of exposed fish. Regarding the liver, the activity of all enzymes and MDA levels increased significantly from the beginning of the experiment except EROD that increased after 15 days of contamination only. At the histological level, fish exhibited pathological symptoms in gills and liver with a predominance of circulatory disturbances in gills and regressive changes in the liver. Our results displayed that peacock blennies are able to survive Cd toxicity due to various physiological adaptation mechanisms.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biomarkers assessment in the peacock blenny <i>Salaria pavo</i> exposed to cadmium","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:57.354305","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"CdCl2; Peacock blenny; Salaria pavo; Cd accumulation; Biomarkers;Transcript levels; Enzyme activity; Histopathology","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2022-05-04","DateCreate":"2017-05-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000381156600047","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s11356-016-6754-6"},"refs":null,"anarec":{"AnaID":285511,"PubliDate":2016,"Pagination":"16296-16312","XtraPublOfAnaID":null,"ISBN":null,"Volume":"23","Issue":"16","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45312,"SerRR":"Environmental Science and Pollution Research.
