The main goal of our study has been to analyze the efficiency of new anticancer drugs, specifically histone deacetylase inhibitors, in tumor cells bearing a multidrug resistance phenotype. We report that the histone deacetylase inhibitors, Trichostatin A and Suberoylanilide Hydroxamic Acid (SAHA), dramatically reduce cell viability and promote apoptosis in different drug-resistant cells, affect...

The antitumor activity of the histone deacetylase inhibitors was tested in three well-characterized pancreatic adenocarcinoma cell lines, IMIM-PC-1, IMIM-PC-2, and RWP-1. These cell lines have been previously characterized in terms of their origin, the status of relevant molecular markers for this kind of tumor, resistance to other antineoplastic drugs, and expression of differentiation markers...

Food Res. 2022, 66, 2200164 DOI: 10.1002/mnfr.202200164 Roseburia hominis alleviates neuroinflammation by producing propionate and butyrate, which serve as histone deacetylase inhibitors of microglia. These findings supplied a new solution to reduce manipulating the microbiota. The inspiration image design comes from an ancient Chinese philosophy “Yin-Yang”. This is reported Liping D...

Eukaryotic organisms from yeast to human contain a multiprotein complex that includes Rpd3 histone deacetylase and Sin3 corepressor. The Sin3-Rpd3 complex, when recruited to promoters by specific DNA-binding proteins, can direct transcriptional repression of specific classes of target genes. It has been proposed that the histone deacetylase activity of Rpd3 is important for repression, but dire...

BACKGROUND The organization of chromatin is crucial for the regulation of gene expression. In particular, both the positioning and properties of nucleosomes influence promoter-specific transcription. The acetylation of core histones has been suggested to alter the properties of nucleosomes and affect the access of DNA-binding transcriptional regulators to promoters. A recently identified mammal...
