Protocol

Kinase Assay [1]
Dose-response studies are done with ten concentrations in a threefold dilution series from a maximum final compound concentration of 100 μM in the reaction mixture. All assays are based on the same principle as the HDAC9 assay described above: the deacetylation of acetylated or trifluoroacetylated lysine residues on fluorogenic peptide substrates by HDAC. HDAC1, HDAC2, HDAC3, HDAC6, HDAC10 and HDAC11 used a substrate based on residues 379-382 of p53 (Arg-His-Lys-Lys(Ac)). For HDAC8, the diacetylated peptide substrate, based on residues 379-382 of p53 (Arg-His-Lys(Ac)-Lys(Ac)), is used. HDAC4, HDAC5, HDAC7 and HDAC9 assays used the class IIa HDAC-specific fluorogenic substrate (Boc-Lys(trifluoroacetyl)-AMC). All reactions are done with 50 μM HDAC substrate in assay buffer (50 mM Tris-HCl, pH 8.0, 137 mM NaCl, 2.7 mM KCl, 1 mM MgCl2, 1 mg/mL BSA) containing 1% DMSO final concentration; incubated for 2 h at 30°C; and developed with trichostatin A and trypsin.

Cell Assay [1]
Human CD4+ T cells are isolated from whole blood via negative selection according to manufacturer's instructions (RosetteSep Human CD4+ T cell enrichment kit), re-suspended in T-cell culture medium (10% FBS, 2 mM L-glutamine, 1 mM pyruvate, 10 mM HEPES, 10 U/10 mg penicillin/streptomycin, 0.5% DMSO in RPMI) and plated at 50,000 cells/well with IL-2 (10 BRMP units/mL) and 100,000 human T-expander Dynabeads for 72 h. Determination of mitochondrial function or cell viability is done according to manufacturer’s instructions (Cell Proliferation Assay Kit I (MTT)) and is represented as a percent of control (no inhibitor) wells.

Background on TMP269

TMP269 is a novel and selective inhibitor of class IIa histone deacetylase with IC50 values of 126, 80, 36, 9 nM for HDAC 4, 5, 7, 9, respectively [1].

Histone deacetylases (HADC) are a series of enzymes that remove acetyl groups from an ε-N-acetyl lysine amino acid on a histone and make the histones to wrap the DNA more tightly, which prevent transcription.

TMP269 is a novel and selective class IIa HDAC inhibitor. In MM cell lines, TMP269 induced modest cytotoxicity with IC50 values ranging from 22 to 38 μM in a dose-dependent way, which was associated with cleavage of caspase-3, -8, -9 and PARP. Also, TMP269 enhanced CFZ-induced apoptosis and increased the expression of activating transcription factor 4 (ATF4) and proapoptotic transcription factor C/EBP homologous protein (CHOP). In the presence of BMSCs or IL-6, TMP269 and CFZ also showed significant cytotoxicity [2]. In IEC-18 intestinal epithelial cells, TMP269 inhibited cell proliferation, cell cycle progression and DNA synthesis in response to G protein-coupled receptor/protein kinase D1 (PKD1) activation [3].

Suppression of triple-negative breast cancer metastasis by pan-DAC inhibitor panobinostat via inhibition of ZEB family of EMT master regulators.[Pubmed:24810497]

Breast Cancer Res Treat. 2014 Jun;145(3):593-604.

Triple-negative breast cancer (TNBC) is a highly aggressive breast cancer subtype that lacks effective targeted therapies. The epithelial-to-mesenchymal transition (EMT) is a key contributor in the metastatic process. We previously showed the pan-deacetylase inhibitor LBH589 induces CDH1 expression in TNBC cells, suggesting regulation of EMT. The purpose of this study was to examine the effects of LBH589 on the metastatic qualities of TNBC cells and the role of EMT in this process. A panel of breast cancer cell lines (MCF-7, MDA-MB-231, and BT-549), drugged with LBH589, was examined for changes in cell morphology, migration, and invasion in vitro. The effect on in vivo metastasis was examined using immunofluorescent staining of lung sections. EMT gene expression profiling was used to determine LBH589-induced changes in TNBC cells. ZEB overexpression studies were conducted to validate requirement of ZEB in LBH589-mediated proliferation and tumorigenesis. Our results indicate a reversal of EMT by LBH589 as demonstrated by altered morphology and altered gene expression in TNBC. LBH589 was shown to be a more potent inhibitor of EMT than other HDAC inhibitors, SAHA and TMP269. Additionally, we found that LBH589 inhibits metastasis of MDA-MB-231 cells in vivo. These effects of LBH589 were mediated in part by inhibition of ZEB, as overexpression of ZEB1 or ZEB2 mitigated the effects of LBH589 on MDA-MB-231 EMT-associated gene expression, migration, invasion, CDH1 expression, and tumorigenesis. These data indicate therapeutic potential of LBH589 in targeting EMT and metastasis of TNBC.

Protein kinase D1 mediates class IIa histone deacetylase phosphorylation and nuclear extrusion in intestinal epithelial cells: role in mitogenic signaling.[Pubmed:24647541]

Am J Physiol Cell Physiol. 2014 May 15;306(10):C961-71.

We examined whether class IIa histone deacetylases (HDACs) play a role in mitogenic signaling mediated by protein kinase D1 (PKD1) in IEC-18 intestinal epithelial cells. Our results show that class IIa HDAC4, HDAC5, and HDAC7 are prominently expressed in these cells. Stimulation with ANG II, a potent mitogen for IEC-18 cells, induced a striking increase in phosphorylation of HDAC4 at Ser(246) and Ser(632), HDAC5 at Ser(259) and Ser(498), and HDAC7 at Ser(155). Treatment with the PKD family inhibitors kb NB 142-70 and CRT0066101 or small interfering RNA-mediated knockdown of PKD1 prevented ANG II-induced phosphorylation of HDAC4, HDAC5, and HDAC7. A variety of PKD1 activators in IEC-18 cells, including vasopressin, lysophosphatidic acid, and phorbol esters, also induced HDAC4, HDAC5, and HDAC7 phosphorylation. Using endogenously and ectopically expressed HDAC5, we show that PKD1-mediated phosphorylation of HDAC5 induces its nuclear extrusion into the cytoplasm. In contrast, HDAC5 with Ser(259) and Ser(498) mutated to Ala was localized to the nucleus in unstimulated and stimulated cells. Treatment of IEC-18 cells with specific inhibitors of class IIa HDACs, including MC1568 and TMP269, prevented cell cycle progression, DNA synthesis, and proliferation induced in response to G protein-coupled receptor/PKD1 activation. The PKD1-class IIa HDAC axis also functions in intestinal epithelial cells in vivo, since an increase in phosphorylation of HDAC4/5 and HDAC7 was demonstrated in lysates of crypt cells from PKD1 transgenic mice compared with matched nontransgenic littermates. Collectively, our results reveal a PKD1-class IIa HDAC axis in intestinal epithelial cells leading to mitogenic signaling.

Class IIa HDAC inhibition enhances ER stress-mediated cell death in multiple myeloma.[Pubmed:25801913]

Leukemia. 2015 Sep;29(9):1918-27.

Histone deacetylase (HDAC) inhibitors have been extensively investigated as therapeutic agents in cancer. However, the biological role of class IIa HDACs (HDAC4, 5, 7 and 9) in cancer cells, including multiple myeloma (MM), remains unclear. Recent studies show HDAC4 interacts with activating transcription factor 4 (ATF4) and inhibits activation of endoplasmic reticulum (ER) stress-associated proapoptotic transcription factor C/EBP homologous protein (CHOP). In this study, we hypothesized that HDAC4 knockdown and/or inhibition could enhance apoptosis in MM cells under ER stress condition by upregulating ATF4, followed by CHOP. HDAC4 knockdown showed modest cell growth inhibition; however, it markedly enhanced cytotoxicity induced by either tunicamycin or carfilzomib (CFZ), associated with upregulating ATF4 and CHOP. For pharmacological inhibition of HDAC4, we employed a novel and selective class IIa HDAC inhibitor TMP269, alone and in combination with CFZ. As with HDAC4 knockdown, TMP269 significantly enhanced cytotoxicity induced by CFZ in MM cell lines, upregulating ATF4 and CHOP and inducing apoptosis. Conversely, enhanced cytotoxicity was abrogated by ATF4 knockdown, confirming that ATF4 has a pivotal role mediating cytotoxicity in this setting. These results provide the rationale for novel treatment strategies combining class IIa HDAC inhibitors with ER stressors, including proteasome inhibitors, to improve patient outcome in MM.
