Levels of DHE accumulation after oxidative stress induced by H₂O₂.

<p>BY4742 (white bars) and <i>Δstf2</i>, <i>pGAL-STF2</i> (grey bars) cells were exposed to 4 mM H₂O₂, and at the indicated times, aliquots were collected to determine the number of DHE-positive cells. The represented data are the means of <i>n</i> = 6 determinations ± the SD. *Significant differences (<i>p</i>≤0.05) for each time with respect to the <i>Δstf2</i>, <i>pGAL-STF2</i> strain.
