Figure 2From: Inhibition of STAT3 signaling and induction of SHP1 mediate antiangiogenic and antitumor activities of ergosterol peroxide in U266 multiple myeloma cells Ergosterol peroxide (EP) inhibits phosphorylation of JAK2 and Src in U266 cells. Cells were treated with 25 μM EP for 0, 4, 8, 16 or 24 h. Whole cell extracts were prepared and subjected to Western blotting to determine level of (A) phospho-JAK2 and JAK2, adn (B) phospho-Src and Src.Back to article page
