The Natural Stilbenoid Piceatannol Decreases Activity and Accelerates Apoptosis of Human Neutrophils: Involvement of Protein Kinase C

Figure 3

. Effect of piceatannol on PKC activity. Neutrophils were incubated with piceatannol (30 min) and stimulated with PMA (3 min). PKC activity was assessed by ELISA kit in the supernatant of cell lysate. The values are presented as percentage of resting control (PKC activity in absence of PMA). Control value given as kinase activity per 1 mg of protein was 13 376±2 417. Mean ± SEM, 𝑛=5, ^∗𝑃≤0.05, ^∗∗𝑃≤0.01  versus PMA.
