Figure Legend Snippet: Pharmacological inhibition of HDACs 1, 2, and 6 enhances the effects of gemcitabine on PDAC cells in vitro and in vivo. ( A.i ) The indicated cells were treated with vehicle, 40 nM gemcitabine (Gem), 8 nM Romidepsin (Rom), and/or 1 µM ACY-1215 (ACY) for 48 h, and the expression of PARP, cleaved caspase 3, and GAPDH was determined by Western blotting. Vertical lines indicate rearrangement of lanes from a single membrane for clarity. Data are representative of three independent experiments. ( A.ii ) PDAC cells treated as in ( i ) were analyzed for apoptosis based on cell surface phosphatidylserine using Annexin V-FITC. Data are means ± s.e. * Significantly different from Gemcitabine and Rom/ACY, p
Techniques Used: Inhibition, In Vitro, In Vivo, Expressing, Western Blot
Figure Legend Snippet: Synergistic interactions of Mocetinostat, LMK-235, and gemcitabine in pancreatic ductal adenocarcinoma (PDAC) cells. ( A ) MiaPaCa-2 cells treated with 100 nM Panobinostat, 10 µM Droxinostat, 10 µM Mocetinostat, or 10 µM LMK-235 for the indicated times and analyzed for poly (ADP-ribose) polymerase (PARP), caspase 7, and GAPDH expression by Western blotting. Arrow indicates the migration of cleaved proteins. ( B.i ) ED 50 values for Mocetinostat and LMK-235 in pancreatic cancer cell lines. ( B.ii ) The indicated cell lines were treated with LMK-235, Mocetinostat, or a combination of LMK-235 and Mocetinostat at a constant ratio. After 72 h, 3-(4,5 Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide (MTT) assays were performed, and the combination index (CI) value for the combination treatment is presented. Dotted line indicates CI value of one, which divides synergistic interaction (CI

Figure Legend Snippet: Inhibition of HDACs 1, 2, and 6 cooperates with gemcitabine. ( A.i,ii ) Capan-1 cells were transfected with non-targeting siRNA (N.T.) or ONTARGET plus SMARTPool siRNAs targeting HDACs 1, 2, and 6 and treated with gemcitabine as indicated for 72 h. ( B.i ) Capan-1 and MiaPaCa-2 cells were treated with the vehicle or the indicated concentrations of ACY-1215 for 24 h, and expression of acetyl-α-Tubulin (ac-α-Tubulin), acetyl-Histone 3 (ac-Histone 3), and GAPDH was assessed by Western blotting. ( ii ) The indicated cells were treated with 1 µM ACY-1215, and the number of viable cells was determined after 72 h. ( C ) The indicated cell lines were treated with Romidepsin, gemcitabine, or a combination of Romidepsin and gemcitabine at a constant ratio in the presence or the absence of 1 µM ACY-1215. After 72 h, CI values for the combination treatment were calculated as in Figure 1 . * Significantly different from Romedepsin + Gemcitabine, p

Figure Legend Snippet: HDACs 1, 2, and 6 account for the synergism between Mocetinostat and LMK-235 in PDAC cells. HDACs 1, 2, and 3 ( A , B ) or HDACs 4, 5, and 6 ( C ) were knocked down (KD) in MiaPaCa-2 and/or Capan-1 cells by transfection with ONTARGET plus SMARTPool siRNAs targeting specific HDACs either individually or in combination, as indicated. Control cells were treated with non-targeting (N.T.) siRNA and, 24 h after transfection, cells were treated with various concentrations of LMK-235 ( A , B ) or Mocetinostat ( C ) and subjected to MTT assay after 72 h of drug treatment. ( i ) Representative graph of the effect of various concentrations of LMK-235 or Mocetinostat on the relative number of viable cells (absorption at 570 nm) following knockdown of the indicated HDACs (mean ± s.d. of six technical replicates for each condition). ( ii ) ED 50 values for LMK-235 ( A , B ) or Mocetinostat ( C ) in cells transfected with the indicated siRNAs (mean ± s.d. for three biological replicates).
