Epigenetic alterations, including DNA acetylation, hypermethylation and hypomethylation, and the associated transcriptional changes of the affected genes are central to the evolution and progression of various human cancers, including pancreatic cancer. Cancer-associated epigenetic alterations are attractive therapeutic targets because such epigenetic alterations, unlike genetic changes, are po...
The antineoplastic activity of HDAC inhibitors is an unquestionable property of these compounds, but recent studies in tumor cells have revealed the potential of HDAC inhibitors (e.g., suberoylanilide hydroxamic acid SAHA, valproic acid VPA) to cause acquisition of HDAC inhibitor resistance. We report that trichostatin A (TSA), an HDAC inhibitor structurally related to SAHA, causes the acquisit...
We focused on the ability of the pan-histone deacetylase (HDAC) inhibitors AR42 and sodium valproate to alter the immunogenicity of melanoma cells. Treatment of melanoma cells with HDAC inhibitors rapidly reduced the expression of multiple HDAC proteins as well as the levels of PD-L1, PD-L2 and ODC, and increased expression of MHCA. In a cell-specific fashion, melanoma isolates released the imm...
Improved prognosis for triple-negative breast cancer (TNBC) has plateaued and the development of novel therapeutic strategies is required. This study aimed to explore anti-tumor effect combined eribulin HDAC inhibitor (vorinostat: VOR, pan-HDAC ricolinostat: RICO, selective HDAC6 inhibitor) treatment TNBC. The in combination with an was tested three TNBC cell lines (MDA-MB-231, Hs578T, MDA-MB-1...
Histone deacetylase (HDAC) inhibitors are emergent cancer drugs. HR23B is a candidate cancer biomarker identified in a genome-wide loss-of-function screen which influences sensitivity to HDAC inhibitors. Because HDAC inhibitors have found clinical utility in cutaneous T-cell lymphoma (CTCL), we evaluated the role of HR23B in CTCL cells. Our results show that HR23B governs the sensitivity of CTC...
Histone deacetylases (HDACs) catalyze the removal of acetyl groups from histones and contribute to transcriptional repression. In addition, the HDAC inhibitors induce apoptosis in cancer cells through alterations in histone acetylation and activation of the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) apoptotic pathway. Lysophosphatidic acid (LPA) is a growth factor that prom...
The MAP kinase pathway inhibitor U0126 in combination with butyrate promotes differentiation in some colon cancer cell lines. We examined several inhibitors of histone deacetylase (HDAC) in combination with U0126 and other protein kinase inhibitors to see if these effects are general properties of HDAC inhibitors or butyrate alone. Alkaline phosphatase and peptidase activities were examined as ...
Histone deacetylase (HDAC) inhibitors are powerful epigenetic regulators that have enormous therapeutic potential and have pleiotropic effects at the cellular and systemic levels. To date, HDAC inhibitors are used clinically for a wide variety of disorders ranging from hematopoietic malignancies to psychiatric disorders, are known to have anti-inflammatory properties, and are in clinical trials...
Cancer cell phenotypes evolve during a tumor's treatment. In some cases, tumor cells acquire cancer stem cell-like (CSL) traits such as resistance to chemotherapy and diminished differentiation; therefore, targeting these may be therapeutically beneficial. this study we show that in progressive estrogen receptor positive (ER+) metastatic breast tumors, resistant subclones emerge following have ...
Major histocompatibility (MHC) class II expression is ordinarily inducible by interferon-gamma (IFN-gamma), but the induction is repressed in retinoblastoma protein (Rb)-defective cells. The repression can be rescued by histone deacetylase (HDAC) inhibitor treatment, but this has never been shown for an HDAC inhibitor that is suitable for clinical trials and eventual patient therapy. Here we de...
