Table 6. Caspase activity of C. albicans cells after AMB treatment⁶.

Strains	2 μg/ml AMB
HSP90/HSP90	50.72±0.49
tetO-HSP90/hsp90	32.22±0.45*
HSP90/HSP90+DOX	51.92±2.34
tetO-HSP90/hsp90+DOX	22.83±0.46*

⁶After treatment with or without 20 μg/ml DOX for 3 h, caspase activity of C. albicans cells was detected flow cytometry after D₂R staining. Three independent experiments were carried out and the results were presented as the mean ± SD of D₂R positive cells percentage. * indicated p<0.05 compared with the wild-type strain group.
