| Abstract: | Using western immunoblotting we obtained heat-shock protein 70 (HSP70) induction data and distribution in different tissues
from shrimpFenneropenaeus chinensis during thermal and immune-challenged stresses. This is probably the first report of the effects of various stressors on the
expression of HSP70 in shrimp. HSP70 was prominently induced in hepatopancreas and gills, but not in muscle, eyestalk and
hemolymph, when the shrimp were exposed to heat shock andVibrio anguillavium-challenged stresses. Cold shock and WSSV treatment had no significant effects on the levels of HSP70 expression in all tissues
examined. HSP70 induction was greatest after 2 h exposure to heat shock stress, which was elevated after acute heat shock
exposure of 10°C above ambient temperature.
