INS-1E cell viability after 20 min or 2 hr incubations. Cell viability was estimated in 3 independent experiments and is expressed in % of viable cells after 20 min (a) and 2 hr (b) incubations, either with no agents added or with 20 μmol·l^-1 rotenone (+Rot) or 1 μmol·l^-1 antimycin A (+Anti), in a medium with 3 mmol·l^-1 glucose (Glc3) or 25 mmol·l^-1 glucose (Glc25). The error bars represent the standard deviation of 3 measurements.
