Trivalent chromium alters gene expression in the mummichog (Fundulus heteroclitus).
Mummichogs (Fundulus heteroclitus) were used as a model fish species to study the effects of trivalent chromium exposure. To ascertain chromium's effects, we examined altered gene expression by differential display between fish exposed in the laboratory and fish collected from a chromium-impacted estuarine site. Twenty differentially expressed genes were found from either laboratory-exposed fis...
متن کاملIntraspecific variation in thermal tolerance and heat shock protein gene expression in common killifish, Fundulus heteroclitus.
Populations of common killifish, Fundulus heteroclitus, are distributed along the Atlantic coast of North America through a steep latitudinal thermal gradient. We examined intraspecific variation in whole-animal thermal tolerance and its relationship to the heat shock response in killifish from the northern and southern extremes of the species range. Critical thermal maxima were significantly h...
متن کاملChanges in gene expression in gills of the euryhaline killifish Fundulus heteroclitus after abrupt salinity transfer.
Maintenance of ion balance requires that ionoregulatory epithelia modulate ion flux in response to internal or environmental osmotic challenges. We have explored the basis of this functional plasticity in the gills of the euryhaline killifish Fundulus heteroclitus. The expression patterns of several genes encoding ion transport proteins were quantified after transfer from near-isosmotic brackis...
متن کاملDose-responsive gene expression changes in juvenile and adult mummichogs (Fundulus heteroclitus) after arsenic exposure.
The present study investigated arsenic's effects on mummichogs (Fundulus heteroclitus), while also examining what role that gender or exposure age might play. Adult male and female mummichogs were exposed to 172 ppb, 575 ppb, or 1720 ppb arsenic as sodium arsenite for 10 days immediately prior to spawning. No differences were noted in the number or viability of eggs between the groups, but ther...
متن کاملHepatic neoplasms in the mummichog Fundulus heteroclitus from a creosote-contaminated site.
High prevalences of idiopathic hepatic lesions were found in mummichog, Fundulus heteroclitus, from a site in the southern branch of the Elizabeth River, VA, contaminated with polycyclic aromatic hydrocarbons. Grossly visible hepatic lesions occurred in a total of 93% of the individuals from this site and 33% of these fish had hepatocellular carcinomas. Hepatic lesions were not detected in fish...
