Reactive Oxygen Species in Unstimulated Hemocytes of the Pacific Oyster Crassostrea gigas: A Mitochondrial Involvement
The Pacific oyster Crassostrea gigas is a sessile bivalve mollusc whose homeostasis relies, at least partially, upon cells circulating in hemolymph and referred to as hemocytes. Oyster's hemocytes have been reported to produce reactive oxygen species (ROS), even in absence of stimulation. Although ROS production in bivalve molluscs is mostly studied for its defence involvement, ROS may also be ...
متن کاملReactive oxygen intermediate production by oyster hemocytes exposed to hypoxia
Oysters are frequently exposed to severely hypoxic conditions, especially during summer months. During the summer, there are also large numbers of disease-related oyster mortalities. This research was conducted to determine whether exposure to environmental hypoxia reduces the ability of oyster hemocytes to produce reactive oxygen intermediates (ROIs), an important part of their defense system....
متن کاملCellular and Transcriptional Responses of Crassostrea gigas Hemocytes Exposed in Vitro to Brevetoxin (PbTx-2)
Hemocytes mediate a series of immune reactions essential for bivalve survival in the environment, however, the impact of harmful algal species and their associated phycotoxins upon bivalve immune system is under debate. To better understand the possible toxic effects of these toxins, Crassostrea gigas hemocytes were exposed to brevetoxin (PbTx-2). Hemocyte viability, monitored through the neutr...

متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
