Targeting histone deacetylases: development of vorinostat for the treatment of cancer.

Články mohou překládat pouze registrovaní uživatelé

Reversible histone acetylation on lysine residues, regulated by the opposing activities of histone acetyltransferases and histone deacetylases (HDACs), plays an important role in the regulation of gene expression. Aberrant gene expression resulting from increased HDAC activity and histone

We evaluated the novel gamma-lactam-based analogue, KBH-A145, for its anticancer activities. KBH-A145 markedly inhibited histone deacetylase (HDAC) activity in vitro and in vivo to an extent comparable to suberoyl-anilide hydroxamic acid (SAHA). The proliferation of various types of cancers was

Histone deacetylase inhibitors: development as cancer therapy.

Přihlášení Registrace

Histone deacetylase (HDAC) inhibitors represent a new class of targeted anticancer agents. A number of structural classes of HDAC inhibitors have been developed of which several are in clinical trials, including phenylbutyrate (PB) and related compounds; the hydroxamic acids, suberoylanilide

Inhibitors of histone deacetylases induce tumor-selective cytotoxicity through modulating Aurora-A kinase.

The molecular basis of the antitumor selectivity of histone deacetylase inhibitors (HDIs) remains unclear. Centrosomal Aurora-A kinase regulates chromosomal segregation during mitosis. The overexpression or amplification of Aurora-A leads to genetic instability, and its inhibition has shown

Combining the pan-aurora kinase inhibitor AMG 900 with histone deacetylase inhibitors enhances antitumor activity in prostate cancer.

Histone deacetylase inhibitors (HDACIs) are being tested in clinical trials for the treatment of solid tumors. While most studies have focused on the reexpression of silenced tumor suppressor genes, a number of genes/pathways are downregulated by HDACIs. This provides opportunities for combination

Histone deacetylase inhibitors as new cancer drugs.

Přihlášení Registrace

Histone deacetylase inhibitors are potent inducers of growth arrest, differentiation, or apoptotic cell death in a variety of transformed cells in culture and in tumor bearing animals. Histone deacetylases and the family of histone acetyl transferases are involved in determining the acetylation of

Calcitriol induces cell senescence of kidney cancer through JMJD3 mediated histone demethylation.

Calcitriol, also known as 1,25-dihydroxyvitamin D3 (1,25(OH)2VD3), is a biologically active form of vitamin D and has a wide range of anticancer activity against various cancer cell lines. However, the mechanism of calcitriol remains to be further studied. In this study, the biological effect and

Association of estrogen receptor alpha and histone deacetylase 6 causes rapid deacetylation of tubulin in breast cancer cells.

Přihlášení Registrace

Estrogen receptor alpha (ERalpha) is a nuclear receptor that functions as a ligand-activated transcription factor. Besides its genomic action in nuclei, ERalpha could exert nongenomic actions at the plasma membrane. To investigate the mechanism underlying the nongenomic action of ERalpha in breast

Complex molecular mechanisms cooperate to mediate histone deacetylase inhibitors anti-tumour activity in neuroblastoma cells.

Přihlášení Registrace

BACKGROUND Histone deacetylase inhibitors (HDACi) are a new class of promising anti-tumour agent inhibiting cell proliferation and survival in tumour cells with very low toxicity toward normal cells. Neuroblastoma (NB) is the second most common solid tumour in children still associated with poor

Histone deacetylase inhibition synergistically enhances pemetrexed cytotoxicity through induction of apoptosis and autophagy in non-small cell lung cancer.

Přihlášení Registrace

BACKGROUND Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. Pemetrexed, a multi-target folate antagonist, has demonstrated efficacy in NSCLC histological subtypes characterized by low thymidylate synthase (TS) expression. Among many other potential targets,

Dual degradation of aurora A and B kinases by the histone deacetylase inhibitor LBH589 induces G2-M arrest and apoptosis of renal cancer cells.

OBJECTIVE This study is aimed at investigating antineoplastic efficacy of histone deacetylase inhibitor (HDACI) LBH589 on renal cell carcinoma (RCC) and elucidating the novel molecular mechanisms involved in growth arrest and apoptosis by targeting the important nonhistone molecules. METHODS We

The histone deacetylase inhibitor PXD101 synergises with 5-fluorouracil to inhibit colon cancer cell growth in vitro and in vivo.

OBJECTIVE Histone deacetylase inhibitors (HDACi) inhibit the growth of cancer cells, and combinations of HDACi with established chemotherapeutics can lead to synergistic effects. We have investigated effects of PXD101 (HDACi in phase II clinical trials) in combination with 5-fluorouracil, on tumour

Histone tail modifications and noncanonical functions of histones: perspectives in cancer epigenetics.

Přihlášení Registrace

Over the past few years, the histone deacetylase (HDAC) inhibitors have occupied an important place in the effort to develop novel, but less toxic, anticancer therapy. HDAC inhibitors block HDACs, which are the enzymes responsible for histone deacetylation, and therefore they modulate gene

Human ZNF312b oncogene is regulated by Sp1 binding to its promoter region through DNA demethylation and histone acetylation in gastric cancer.

Přihlášení Registrace

In a previous study, human ZNF312b was identified as a cell proliferation-associated oncogene via the K-ras/extracellular signal-regulated kinase cascade in gastric cancer. However, the mechanism concerning its transcriptional activation remains unknown. Here, we show that DNA methylation and

Soybean (Glycine max) prevents the progression of breast cancer cells by downregulating the level of histone demethylase JMJD5.
