... to the seasonal maximum temperature (33°C). Metabolomic analysis highlighted the elevated content of glycerophospholipids in all heat-hardened clams, which may help to maintain the structure and function of the membrane. Heat shock proteins (HSPs) tended to be upregulated after heat hardening at 37°C...

Differences in the capacities to maintain ATP synthesis rates and to induce heat shock proteins at high temperatures, two likely mechanisms of local adaptation in this species, were consistent...

... and was negative at 24°C, with an estimated upper limit for positive growth of 23.4°C. Plasma cortisol increased with temperature and was 12- and 18-fold higher at 22 and 24°C, respectively, than at 16°C, whereas plasma glucose was unaffected by temperature. Abundance of heat shock protein 70 (HSP70) in the gill...

The upregulation of genes involved in carbohydrate metabolic processes initiated during RCH was likely responsible for a transient accumulation...

We...

To elucidate the mechanism responsible for the lack of Hsp induction, we examined several...

Recently,several families of heat shock proteins (hsps) have been proposed as indicators of a generalized stress response at the cellular level. Recent findings...
