Effects of Hsp90 inhibitors on LANA in KSHV-infected endothelial cells.
(A) L1T2 cells were treated with AUY922 at concentrations of 0, 0.02, 0.1, 0.5, and 2.5 µM for 48 hours, whole cell lysates were immunoblotted with anti-LANA, anti-Hsp90 antibodies, anti-EphA2, anti-Ephrin-B2, and anti-Akt (total), and anti-pAkt (S473) antibodies separately. Apoptosis was evaluated with anti-cleaved PARP and anti-cleaved Caspase-3 antibodies, Cdc2 and β-Actin were used as controls. (B–C) SLK-KSHV were treated with 0.5 µM 17-DMAG for 0, 12, 24, 48, 72 and 96 hours, or at concentrations of 0, 0.1, 0.5, 2.5 and 10 µM for 48 hours separately, whole cell lysates were immunoblotted with anti-LANA antibody, anti-EphA2, anti-EphrinB2, Cdc2 and β-Actin were used as controls.
