EAC cells were isolated from mice and incubated in a glucose-free medium containing blocators of mitochondrial ATP generation (rotenone, 2,4-dinitrophenol, or oligomycin).
In contrast to the exponentially growing cells, thermotolerance and unexpected expression of inducible HSP68 and HSP27 as well as an elevated level of HSP90 were found in stationary EAC.

Ehrlich carcinoma (EC) cells isolated from mice at different phases of ascites growth were exposed to hyperthermia (44 degrees C), or oxidative stress (hydrogen peroxide or vikasol), or ATP depletion induced by rotenone.
Comparative immunoblotting has revealed the unexpected expression of inducible 70 kDa heat-shock protein form (HSP68), as well as accumulation of HSP27 and HSP90 in the thermo- and drug-resistant stationary EC cells.

PGA1 increased the expression of HSP70 and HSP27 and protected against rotenone-induced apoptosis, without increasing necrotic death.
