Aging and cancer both occur as a result of accumulated cellular damage, and both are related to the regulation of specific genes in the damage response. Recent research has unveiled connections between the mechanisms of aging and cancer, but how to prevent the development of cancer and increase longevity remain unknown. SIRT1 (the mammalian Sir2), which has NAD(+)-dependent class III histone de...
Three new bicyclic depsipeptides, which are related to the previously reported thailandepsins A (1), B (2) and C (3), were discovered from the culture broth of Burkholderia thailandensis E264 when supplemented with amino acid precursors, and were subsequently named as thailandepsins D (4), E (5) and F (6), respectively. Enzyme assays showed that 1-6 are potent histone deacetylase (HDAC) inhibit...
We report the development of a potent, selective histone deacetylase 6 (HDAC6) inhibitor. This HDAC6 inhibitor blocks growth of normal and transformed cells but does not induce death of normal cells. The HDAC6 inhibitor alone is as effective as paclitaxel in anticancer activity in tumor-bearing mice.

All organisms have evolved to cope with changes in environmental conditions, ensuring the optimal combination of proliferation and survival. In yeast, exposure to a mild stress leads to an increased tolerance for other stresses. This suggests that yeast uses information from the environment to prepare for future threats. We used the yeast knockout collection to systematically investigate the ge...

Moraxella catarrhalis induces inflammatory response of bronchial epithelial cells via MAPK and NFB activation and histone deacetylase activity reduction. Am J Physiol Lung Cell Mol Ph...
BACKGROUND Chronic methamphetamine (METH) exposure causes neuroadaptations at glutamatergic synapses. METHODS To identify the METH-induced epigenetic underpinnings of these neuroadaptations, we injected increasing METH doses to rats for 2 weeks and measured striatal glutamate receptor expression. We then quantified the effects of METH exposure on histone acetylation. We also measured METH-ind...
Alzheimer's disease is a very common progressive neurodegenerative disorder affecting the learning and memory centers in the brain. The hallmarks of disease are the accumulation of β-amyloid neuritic plaques and neurofibrillary tangles formed by abnormally phosphorylated tau protein. Alzheimer's disease is currently incurable and there is an intense interest in the development of new potential ...
Aberrant expression of epigenetic regulators of gene expression contributes to initiation and progression of cancer. During recent years, considerable research efforts have focused on the role of histone acetyltransferases (HATs) and histone deacetylases (HDACs) in cancer cells, and the identification of pharmacologic agents that modulate gene expression via inhibition of HDACs. The following r...
