NO = nitric oxide; PKC = protein kinase C; PMA = phorbol myristate acid.
MRL/lpr spleen lymphocytes were cultured overnight in varying concentrations of Deta NONOate (0–1,000 μM) with or without PMA (10 ng/mL). Cells were analyzed by flow cytometry for the percentage of apoptotic cells present. The results reported are a percentage (± standard error) of the control wells (no additive) and were the average of triplicate readings from three different experiments. Cells were also analyzed for PKC activity in two separate experiments.
