Estuaries are characterized by extreme fluctuations in CO(2) levels due to bouts of production the resident biota that exceed its capacity consumption and/or rates gas exchange with atmosphere and open ocean waters. Elevated partial pressures (P(CO(2)); i.e. environmental hypercapnia) decrease pH estuarine waters and, ultimately, extracellular intracellular organisms such as mollusks have limited for regulation. We analyzed proteomic changes associated exposure elevated P(CO(2)) mantle...
SUMMARY Rising levels of atmospheric CO2 lead to acidification the ocean and alter seawater carbonate chemistry, which can negatively impact calcifying organisms, including mollusks. In estuaries, exposure elevated often co-occurs with other stressors, such as reduced salinity, enhances trend, affects ion acid–base regulation estuarine calcifiers modifies their response acidification. We studied interactive effects salinity partial pressure (PCO2) on biomineralization energy homeostasis in...
Abstract Changes in the global environment such as ocean acidification (OA) may interact with anthropogenic pollutants including trace metals threatening integrity of marine ecosystems. We analyze recent studies on interactive effects OA and organisms a focus physiological basis these interactions. Our analysis shows that responses to elevated CO2 are strongly dependent species, developmental stage, metal biochemistry degree environmental hypercapnia, cannot be directly predicted from...
ABSTRACT Fluctuations in oxygen (O2) concentrations represent a major challenge to aerobic organisms and can be extremely damaging their mitochondria. Marine intertidal molluscs are well-adapted frequent O2 fluctuations, yet it remains unknown how mitochondrial functions regulated sustain energy metabolism prevent cellular damage during hypoxia reoxygenation (H/R). We used metabolic control analysis investigate the mechanisms of responses H/R stress (18 h at <0.1% followed by 1...
Cadmium (Cd) is an important toxicant in estuarine and coastal environments that can strongly affect energy balance of aquatic organisms by increasing the organism's basal demand reducing its aerobic capacity. Mechanisms cadmium-induced increase metabolic costs are not well understood may involve elevated detoxification due to synthesis cellular protective proteins glutathione. We studied short-term effects cadmium exposure (4 h) on protein glutathione (GSH) expression stress (heat shock...
We introduce a new concept that utilizes cognate nucleic acid nanoparticles which are fully complementary and functionally-interdependent to each other. In the described approach, physical interaction between sets of designed initiates rapid isothermal shape change triggers activation multiple functionalities biological pathways including transcription, energy transfer, functional aptamers RNA interference. The individual not active have controllable kinetics re-association fine-tunable...
Benthic marine organisms such as mollusks are often exposed to periodic oxygen deficiency (due the tidal exposure and/or seasonal expansion of oxygen-deficient dead zones) and pollution by metals [e.g., cadmium, (Cd)]. These stressors can strongly affect mollusks' survival; however, physiological mechanisms their combined effects not fully understood. We studied Cd on metabolic responses prolonged anoxia subsequent recovery in anoxia-tolerant intertidal Crassostrea virginica (eastern...
Summary Marine organisms such as bivalves that live in estuarine and coastal zones are exposed to multiple stressors include periodic anoxia, temperature fluctuations pollution, all of which can strongly affect energy metabolism. In this study, we used top-down control elasticity analyses determine the interactive effects these on mitochondria an intertidal bivalve, eastern oyster Crassostrea virginica. Oysters were acclimated at 20°C for 30 days absence or presence 50μg L-1 cadmium (Cd)...
Oxygen fluctuations represent a common stressor in estuarine and intertidal environments can compromise the mitochondrial integrity function marine organisms. We assessed role of protection mechanisms (ATP-dependent -independent proteases, antioxidants) tolerance to intermittent hypoxia or anoxia three species bivalves: hypoxia-tolerant hard clams (Mercenaria mercenaria) oysters (Crassostrea virginica), hypoxia-sensitive subtidal scallop (Argopecten irradians). In oysters, (18 h at 5% O2),...
Molluscan exoskeleton (shell) plays multiple important roles including structural support, protection from predators and stressors, physiological homeostasis. Shell formation is a tightly regulated biological process that allows mollusks to build their shells even in environments unfavorable for mineral precipitation. Outer mantle edge epithelial cells (OME) hemocytes were implicated this process; however, the exact functions of these cell types biomineralization are not clear. The Pacific...
