To determine whether cellular resistance to a given stressor is related to induction of specific stress-proteins, responses of two adapted Euglena gracilis cell lines, one adapted to cadmium, the other adapted to pentachlorophenol, were analyzed. Our experiments showed that two sets of heat-shock proteins (hsps) were constitutively overexpressed in each cell line: while hsp90, hsp70, hsp55, and hsp40 were induced in cadmium-resistant cells, only hsp40 was induced in pentachlorophenol-adapted cells.
