Histone deacetylase (HDAC) inhibitors increase histone acetylation and enhance both memory and synaptic plasticity. The current model for the action of HDAC inhibitors assumes that they alter gene expression globally and thus affect memory processes in a nonspecific manner. Here, we show that the enhancement of hippocampus-dependent memory and hippocampal synaptic plasticity by HDAC inhibitors ...
In this report, we describe new HDAC inhibitors designed to exploit a unique sub-pocket in the HDAC8 active site. These compounds were based on inspection of the available HDAC8 crystal structures bound to various inhibitors, which collectively show that the HDAC8 active site is unusually malleable and can accommodate inhibitor structures that are distinct from the canonical 'zinc binding group...
Chromatin modifications are sensitive to environmental and nutritional stimuli. Abnormalities in epigenetic regulation are associated with metabolic disorders such as obesity and diabetes that are often linked with defects in oxidative metabolism. Here, we evaluated the potential of class-specific synthetic inhibitors of histone deacetylases (HDACs), central chromatin-remodeling enzymes, to ame...
The naturally occurring cyclic tetrapeptide chlamydocin is a very potent inhibitor of cell proliferation. Here we show that chlamydocin is a highly potent histone deacetylase (HDAC) inhibitor, inhibiting HDAC activity in vitro with an IC(50) of 1.3 nM. Like other HDAC inhibitors, chlamydocin induces the accumulation of hyperacetylated histones H3 and H4 in A2780 ovarian cancer cells, increases ...
Current systemic therapies have little curative benefit for synovial sarcoma. Histone deacetylase (HDAC) inhibitors and the heat shock protein 90 (Hsp90) inhibitor 17-AAG have recently been shown to inhibit synovial sarcoma in preclinical models. We tested combinations of 17-AAG with the HDAC inhibitor MS-275 for synergism by proliferation and apoptosis assays. The combination was found to be s...
Autophagy is an essential process of the eukaryotic cell allowing degradation and recycling of dysfunctional or non-functional cellular components either in response to physiological or pathological changes [1]. Beside proteasomemediated degradation, baseline autophagy serves as a major cellular pathway for long-lived protein and organelle turnover maintaining a well-balanced equilibrium betwee...
Histone deacetylase (HDAC) has emerged as a new molecular target in the control of obesity and type 2 diabetes. HDAC is an enzyme with well-known functions in the regulation of chromatin structure and gene transcription in the nucleus, where HDAC interacts with corepressor proteins such as NcoR and SMRT to form active corepressor complexes. In the corepressor complex, HDAC catalyzes removal of ...
A fluorescence-based cellular assay system was established to identify potential epigenetic modulator ligands. This assay method is to detect the de-repression of an EGFP reporter in cancer cells by the treatment of HDAC (histone deacetylase) or DNMT (DNA methyltransferase) inhibitor. Using this system, we conducted a preliminary screening of in-house natural product library containing extracts...
