Panobinostat (LBH589)

PubMed: 19279403      Cancer Biol Ther

Western blot of DNMT1 and EZH2 in K562 and LAMA84 following 24 hours treatment with the indicated doses of panobinostat (PS). The levels of β-actin served as the loading control.

The indicated MM cell lines were cultured for 24 hours in the absence or presence of panobinostat at the indicated concentrations. Then, the protein levels of caspase-8, cleaved caspase 8 and Sp1 were analyzed by Western blotting.

Immunoblotting of whole cell lysates prepared from MB cells treated with panobinostat. The representative western blot result shows panobinostat clearly regulated acetyl-Histone H3 (Ac-H3), cleaved caspase-3, CCND1, IDs, synaptophysin and NeuroD1.

CTS, OCI-AML3 or U937 AML cells were treated with variable concentrations of panobinostat for 48 h. Whole cell lysates were subjected to Western blotting to measure protein levels for BRCA1, CHK1, and RAD51 in the cells.

Immunoblot analyses of histone acetylation (H3K9AC, H3K18AC, H3K56AC, H4K8AC and H4K16AC), cell cycle arrest (p27 and p27) and apoptotic-related protein (C-Caspase 3 and C-PARP) expression following various panobinostat treatments for 6 h and 24 h on K562 cells. H3, H4 and GAPDH immunoblots served as internal controls.

CLBL-1 cells were treated with 10 nM of panobinostat for 24 h and then microtubules were visualized by immunofluorescence labeling using antibodies against tubulin and acetylated tubulin (ac-tubulin) using the appropriate excitation and emission filters as described in the material and methods section. Representative microphotographs with tubulin and ac-tubulin labeling (green) and DAPI stained-nuclei (blue) at 100× magnification are shown. Scale bar, 5 μm.

Immunofluorescence analysis of BiP after 24 and 48 hours of treatment in HepG2 (upper panel) and Hep3B (lower panel) cells with 0.1 µM panobinostat and 10 nM thapsigargin, showing an increase and a different protein distribution in panobinostat-treated cells, comparable to 10 nM thapsigargin effect, used as a positive control. Immunofluorescence analysis has been performed under identical settings. Nuclei were stained with Hoechst 33342. Magnification is x630, and scale bar represents 10 µm.

HepG2 (left panel) and Hep3B (right panel) cells were treated for 24 and 48 hours with 0.1 µM panobinostat and the immunofluorescence results show an increase of ATF4 and its nuclear localization in both cell lines. Immunofluorescence analysis has been performed under identical settings. Nuclei were stained with Hoechst 33342. Magnification is x630, and scale bar represents 10 µm.

Analysis of IRE1α/XBP1 involvement. Immunofluorescence results of IRE1α and its phosphorylated form in HepG2 (A) and Hep3B (B) cell lines after 24 and 48 hours of treatment with 0.1 µM panobinostat. The results indicate that panobinostat induces an increase of both the total and the phosphorylated form of IRE1α and a spotted distribution of this protein (enlargement showed for phospho-IRE1α, B). Immunofluorescence analysis has been performed under identical settings. Nuclei were stained with Hoechst 33342. Magnification is x630, and scale bar represents 10 µm.

The indicated MM cell lines were cultured in triplicate in the absence or presence of panobinostat at the indicated concentrations. After culturing for 48 hours, cell viability was measured by a WST-8 cell proliferation assay. Results were expressed as the mean +/− SD.
