| Crassostrea gigas is a marine invertebrate that inhabits the intertidal zone and therefore, is commonly exposed to multiple environmental stressors, including temperature. In recent years mass mortality events have been reported in Mexico in C. gigas associated with the increase in temperature during the summer. Organisms under thermal stress present an increase in prostaglandins (PG) production by cyclooxygenases (COX), an enzymatic route using arachidonic acid (ARA) present in the phospholipids (FL) of the cell membrane as substrate, but PG can also increase non-enzymatically by reactive oxygen species (ROS) that are produced during increased metabolism. It has been reported that some organisms exposed to stress accumulate a higher concentration of ARA... |
