Figure 3. VPA inactivates STAT3 in NK cells.
(A) Expression and phosphorylation of STAT3 in purified primary NK cells with or without treatment with 1.0 μM entinostat or 0.1 mM VPA. (B) Phosphorylation of STAT1 and STAT5 in purified primary NK cells with or without treatment with 0.1 mM VPA and IL-2. Similar results were obtained in three independent experiments.
