Cholangiocarcinoma (CCA) is a highly invasive and metastatic form of carcinoma with bleak prognosis due to limited therapies, frequent relapse, and chemotherapy resistance. There is an urgent need to identify the molecular regulators of CCA in order to develop novel therapeutics and advance diseases diagnosis. Many cellular proteins including histones may undergo a series of enzyme-mediated post-translational modifications including acetylation, methylation, phosphorylation, sumoylation, and crotonylation. Histone deacetylases (HDACs) play an important role in regulating epigenetic maintenance and modifications of their targets, which in turn exert critical impacts on chromatin structure, gene expression, and stability of proteins. As such, HDACs constitute a group of potential therapeutic targets for CCA. The aim of this review was to summarize the role that HDACs perform in regulating epigenetic changes, tumor development, and their potential as therapeutic targets for CCA.

The Brain

Previous studies provided evidence for the alteration of brain cholesterol homeostasis in 129.Mecp2-null mice, an experimental model of Rett syndrome. The efficacy of statins in improving motor symptoms and prolonging survival of mutant mice suggested a potential role of statins in the therapy of Rett syndrome. In the present study, we show that Mecp2 deletion had no effect on brain and reduced serum cholesterol levels and lovastatin (1.5 mg/kg, twice weekly as in the previous study) had no effects on motor deficits and survival when Mecp2 deletion was expressed on a background strain (C57BL/6J; B6) differing from that used in the earlier study. These findings indicate that the effects of statins may be background specific and raise important issues to consider when contemplating clinical trials. The reduction of the brain cholesterol metabolite 24S-hydroxycholesterol (24S-OHC) found in B6.Mecp2-null mice suggests the occurrence of changes in brain cholesterol metabolism and the potential utility of using plasma levels of 24S-OHC as a biomarker of brain cholesterol homeostasis in RTT.

ABSTRACT A clear relationship exists between histone acetylation and transcriptional output, the balance of which is conferred by opposing histone acetyltransferases (HATs) and histone deacetylases (HDACs). To explore the role of HDAC activity in determining the transcriptional competency of chromatin, we have exploited the biological features ofTetrahymena as a model. Each vegetative cell contains two nuclei: a somatic, transcriptionally active macronucleus containing hyperacetylated chromatin and a transcriptionally silent, germ line micronucleus containing hypoacetylated histones. Using a PCR-based strategy, a deacetylase gene (named THD1) encoding a homolog of the yeast HDAC Rpd3p was cloned. Thd1p deacetylates all four core histones in vitro. It resides exclusively in the macronucleus during vegetative growth and is asymmetrically distributed to developing new macronuclei early in their differentiation during the sexual pathway. Together, these data are most consistent with a potential role for Thd1p in transcriptional regulation and suggest that histone deacetylation may be important for the differentiation of micronuclei into macronuclei during development.
