Global temperature is increasing due to anthropogenic activities and the effects of elevated on DNA lesions are not well documented in marine organisms. The American oyster (Crassostrea virginica, an edible commercially important mollusk) ideal shellfish species study oxidative during heat stress. In this study, we examined temperatures (24, 28, 32 °C for one-week exposure) shock protein-70 (HSP70, a biomarker stress), 8‑hydroxy-2'-deoxyguanosine (8-OHdG, pro-mutagenic lesion), double-stranded (dsDNA), γ-histone family member X (γH2AX, molecular damage), caspase-3 (CAS-3, key enzyme apoptotic pathway) Bcl-2-associated (BAX, apoptosis regulator) protein and/or mRNA expressions gills oysters. Immunohistochemical qRT-PCR results showed that HSP70, 8-OHdG, dsDNA, γH2AX were significantly increased at high (28 °C) compared with control (24°C). situ TUNEL analysis cells gill tissues heat-exposed Interestingly, enhanced associated CAS-3 BAX expressions, along 8-OHdG levels after exposure. Moreover, extrapallial (EP) fluid (i.e., extracellular body fluid) concentrations lower; however, EP glucose higher Taken together, these suggest shock-driven stress alters conditions induces cellular damage, which may lead cells/tissues
