Using CRISPR-Cas9 technology, ERα was silenced at the genomic level in ECC1 cells. Ishikawa, parental ECC1 cells and individual ESR1 KO ECC1 clones were treated with 20 nM LBH589 for 24 hr. Expression of ERα, PR, FOXO1, and Myc were evaluated by Western blotting. β-actin serves as a loading control.

HDACIs That Simultaneously Inhibit HDACs 1 and 6 Showed Greater Antileukemic Activities than HDACIs that Don’t at Cmax Concentrations. THP-1 cells were treated with LBH-589, PXD101, SAHA, VPA, MS-275 and MGCD0103 at Cmax concentrations for 3 h and 24 h, respectively. The cells post 3 h treatments were washed three times with complete medium and divided into two halves. One half of the cells was resuspended in complete media and cultured for up to 24 h to determine the effects of the 3 h treatments on cell proliferation and apoptosis. The other half of the cells was used to prepare whole cell lysates. Whole cell lysates from the 3 h and 24 h treatments were extracted and subjected to Western blots probed by anti-ac-tubulin or –b-actin antibody (panels A&B), or subjected to HDAC1 enzymatic assays post IP as described in the Materials and Methods (Panels C&D). The effects of the 3 h and 24 h HDACI treatments on cell proliferation, as reflected by percent decrease of live cells relative to untreated cells (panel E), and apoptosis (panel F) were determined by flow cytometry analysis as described in the Materials and Methods.

Induction of DNA Damage and Bim Is Critical for HDACI-Induced Apoptosis in Pediatric AML Cells. THP-1 cells were treated with the HDACIs at Cmax concentrations for 3 (panel A) and 24 h (panel B), respectively. Whole cell lysates were extracted and subjected to Western blots probed by anti-p21, -c-Myc, -cH2AX, -Bim, or -b-actin antibody.

Expression of pro-/anti-apoptosis genes. Control or MTDH knockdown Hec50co cells were treated for 24 hours with vehicle control, 20 nM LBH589, 25 ng/ml TRAIL or LBH589 and TRAIL at the concentrations noted. Lysates were collected. Expression of DR4, DR5, and apoptosis related caspase-3, caspase-8, PARP-1, BID, FLIP, XIAP, Bim, MCL-1 and BCL-XL was analyzed by Western blotting.

p53(+/+) and (/) HCT116 cells were treated with TSA (1–5 lM),LBH589 (2–5 lM), valproate (2.5–5 mM), MS-275 (20 lM) and sodium butyrate (2 mM). TAp63 expression was compared in both cell lines after 24 h of treatment. Consistent with the above data, all HDAC inhibitors failed to induce significant levels of TAp63 in p53(/) HCT116 cells.

Effect of panobinostat on the viability of cervical cancer cells. HeLa (A) and SiHa (B) cells were treated with increasing concentrations of panobinostat for 24, 48 and 72 h. Cell viability was determined by MTT assay. The results are presented as percentage; calculated from the reduction in cell viability at a given concentration of drug compared to the untreated control (untreated control being 100%). The IC5072h values were calculated from sigmoidal dose-response curves generated in Prism 5.0 (GraphPad). (C) Cytotoxic effects of panobinostat on HeLa and SiHa cells measured at 72 h and expressed as% cell death. Each value is the mean ± SD of three independent experiments performed in triplicates.

HDAC inhibitors induce p63a expression (A) HCT116 cells were treated with TSA (1 lM), LBH589 (2 lM), valproate (2.5 mM), MS-275 (20 lM) and sodium butyrate(2 mM) for 24 h. Expression of p63 was assessed by Western blotting with the H129 pan-anti-p63 antibody. Although TSA and LBH589 induced p63 efficiently, valproate, MS-275 and sodium butyrate were much less efficient. The lower panel shows the actin loading control. Arrow indicates TAp63. (B) The HDAC inhibitors used in this study are shown, grouped according to their structure and with their HDAC specificity. The efficiency of TAp63 expression is shown in the last column.

U266 and KMS-11 were treated with 20 nM panobinostat for 48 h followed by Western blot analysis. Actin served as a loading control. Nine (U266) and 3 (KMS-11) biologically independent experiments were performed. To determine the expression of PPP3CA mRNA in treated cells for 24 h, we performed relative quantification real-time PCR (n = 6). Four (U266) and 2 (KMS-11) biologically independent experiments were performed.

LBH589 induces apoptosis among MOLT-4 and Reh cells in a time- and dose-dependent manner. Moreover, LBH589 is more potent in MOLT-4 than in Reh cells. LBH589 markedly prevents the growth of both MOLT-4 and Reh cells in a dose-dependent manner at 48 hours. LBH589 treatment causes a 2- to 3-fold increase in the number of cells in the G2/M phase of the cell cycle compared with the control cells. LBH589 is associated with induction of histone H3K9 and histone H4K8 acetylation as well as decreasing levels of c-Myc expression in a dose-dependent manner. LBH589 treatment also increases the levels of p21 expression. LBH589 treatment also decreases the levels of c-Myc after an initial increase at the lowest dose (10 nM) in Reh cells. In addition, LBH589 gives rise to substantial increases in mRNA levels of proapoptosis and DNA repair genes. LBH589 induces increased levels of acetylated histone H3 and H4 at the GADD45G promoter. [1] Besides, LBH589 inhibits growth of non small cell lung cancer cell lines (such as human H1299, L55 and A549 with IC50 of 5 nM, 11 nM and 30 nM, respectively), mesothelioma (such as human OK-6 and Ok-5 with IC50 of 5 nM and 7 nM, respectively) and small cell lung cancer cell lines (such as human RG-1 and LD-T with IC50 of 4 nM and 5 nM, respectively).

| In vivo | In lung cancer and mesothelioma animal models, LBH589 markedly decreases tumor growth by 62%. LBH589 is equally effective in immunocompetent and severe combined immunodeficien-cymice, suggesting that the inhibition of tumor growth by LBH589 is not due to direct immunologic effects. Daily LBH589, given i.p. at 20 mg/kg for 5 days per week, leading to an average decrease in growth of 70%. Compared with the corresponding control tumors, LBH589 leads to a 53% decrease for H526-derived tumors, an 81% decrease for BK-T-derived tumors, a 76% decrease for RG-1- derived tumors, and a 70% decrease for H69-derived tumors. In contrast to the lack of tumor regression notes in NSCLC and Meso-derived xenografted tumors that are treated under identical conditions and doses, LBH589 results in dramatic tumor regression in SCLC-derived tumors and RG-1-derived tumor.
