SUMMARY Using quantitative real-time PCR, the expression of mRNAs encoding three transport-related proteins and one putative housekeeping protein was analyzed in anterior posterior gills euryhaline crab Chasmagnathus granulatus following transfer from isosmotic conditions (30‰salinity) to either dilute (2‰) or concentrated (45‰) seawater. Modest changes were observed abundance arginine kinase vacuolar-type H+-ATPase B-subunit, both which highly expressed under all conditions. By contrast,...
Hypoxia in freshwater ecosystems is spreading as a consequence of global change, including pollution and eutrophication. In the Patagonian Andes, decline precipitation causes reduced lake water volumes stagnant conditions that limit oxygen transport exacerbate hypoxia below upper mixed layer. We analyzed molecular biochemical response North bivalve Diplodon chilensis after 10 days experimental anoxia (< 0.2 mg O2 / L), (2 normoxia (9 L). Specifically, we investigated expression an...
The development of oil and gas production together with the fruit in nearby areas North Patagonia, Argentina, suggests aquatic pollution scenarios which include permanent combined short events pesticides application. It has been reported that hydrocarbons activate aryl hydrocarbon receptor (AhR) pathway rainbow trout, Oncorhynchus mykiss, insecticide Chlorpyrifos (CPF) interacts these effects. Thus, it is interesting to investigate whether insecticides, applied by separate or combined, can...
SUMMARY Split lamellae of posterior gills Chasmagnathus granulatusadapted to 2.5‰ salinity were mounted in a modified Ussing chamber. With NaCl-saline on both sides the preparation transepithelial voltage(Vte) 4.1±0.5 mV (outside positive) was measured. After voltage-clamping, negative short-circuit current(Isc) amounted -142±21 μA cm-2 at conductance (Gte) 44±5 mS cm-2. Substitution either chloride (by nitrate) or sodium choline) split gill significantly reduced Isc 70-80%) and Gte 30-50%)....
Posterior isolated gills of Neohelice ( Chasmagnathus) granulatus were symmetrically perfused with hemolymph-like saline varying [HCO 3 − ] and pH. Elevating in the from 2.5 to 12.5 mmol/l (pH 7.75 both cases) induced a significant increase transepithelial potential difference V te ), measure ion transport. The elevation also switch acid secretion (−43.7 ± 22.5 μequiv·kg −1 ·h ) controls base (84.7 14.4 ). HCO -induced was inhibited by basolateral acetazolamide (200 μmol/l), amiloride (1...
