Harmful algal bloom toxins alter c-Fos protein expression in the brain of killifish, Fundulus heteroclitus.
The immediate early gene c-fos, and its protein product c-Fos, are known to be induced in neurons of mammals and fish as a result of neuronal stimulation. The purpose of this study was to quantitatively examine CNS alterations in killifish, Fundulus heteroclitus, in relation to harmful algal bloom (HAB) toxin exposure. c-Fos expression was visualized using immunocytochemistry in the brains of k...
متن کاملEndocrinological Studies on the Euryhaline Killifish, Fundulus Heteroclitus (Linn.) **
The common killifish of the eastern United States, Fundulus heteroclitus (Linn.), is widely employed as an experimental animal by zoologists, em-bryologists, and comparative physiologists. The late Dr. Myron Gordon8' points out that it is a hardy species of convenient size, readily caught in tidal pools but not usually bred in aquaria for purposes of raising the stock. Dr. Gordon warns against ...
متن کاملRole of glucocorticoid receptor in acclimation of killifish (Fundulus heteroclitus) to seawater and effects of arsenic.
Killifish are euryhaline teleosts that adapt to rapid changes in the salinity of the seawater. It is generally accepted that acclimation to seawater is mediated by cortisol activation of the glucocorticoid receptor (GR), which stimulates CFTR mRNA expression and CFTR-mediated Cl- secretion by the gill. Because there is no direct evidence in killifish that the GR stimulates CFTR gene expression,...
متن کاملMRP2 and acquired tolerance to inorganic arsenic in the kidney of killifish (Fundulus heteroclitus).
We used proximal tubules isolated from the killifish, Fundulus heteroclitus, to examine the effect of environmentally relevant, sublethal levels of arsenic on the function and expression of MRP2, an ABC transporter that transports xenobiotics into urine, including arsenic-glutathione conjugates. Exposure of fish to arsenic as sodium arsenite (4-14 days) increased both MRP2 expression in the api...
متن کاملDifferential sensitivity to pro-oxidant exposure in two populations of killifish (Fundulus heteroclitus).
New Bedford Harbor (MA, U.S.A.; NBH) is a Superfund site inhabited by Atlantic killifish (Fundulus heteroclitus) with altered aryl hydrocarbon receptor (Ahr) signaling, leading to resistance to effects of polychlorinated biphenyls (PCBs) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The Ahr is a transcription factor that regulates gene expression of many Phase I and II detoxifying enzymes and...
