Myc-mediated transcriptional repression by recruitment of histone deacetylase.

Myc is a transcription factor that features prominently in cancer. The oncogenicity of Myc stems from its ability to regulate expression of genes required for cell growth and proliferation. Although the mechanisms through which Myc activates transcription have been extensively studied, less is known about how Myc represses transcription. Recently, we reported that a conserved element within Myc...

Transcriptional repression by sumoylation of Epstein-Barr virus BZLF1 protein correlates with association of histone deacetylase.

The transition from latent to lytic phases of the Epstein-Barr virus life cycle is triggered by expression of a viral transactivator, BZLF1, that then induces expression of the viral immediate-early and early genes. The BZLF1 protein is post-translationally modified by a small ubiquitin-related modifier-1 (SUMO-1). Here we found that BZLF1 is conjugated at lysine 12 not only by SUMO-1 but also ...

Histone deacetylase inhibitors stimulate histone H3 lysine 4 methylation in part via transcriptional repression of histone H3 lysine 4 demethylases.

This study investigates the mechanism by which histone deacetylase (HDAC) inhibitors up-regulate histone H3 lysine 4 (H3K4) methylation. Exposure of LNCaP prostate cancer cells and the prostate tissue of transgenic adenocarcinoma of the mouse prostate mice to the pan- and class I HDAC inhibitors (S)-(+)-N-hydroxy-4-(3-methyl-2-phenyl-butyrylamino)-benzamide (AR42), N-(2-aminophenyl)-4-[N-(pyrid...

SRC proximal and core promoter elements dictate TAF1 dependence and transcriptional repression by histone deacetylase inhibitors.

Histone deacetylase inhibitors (HDIs) induce cell cycle arrest, differentiation, or apoptosis in numerous cancer cell types both in vivo and in vitro. These dramatic effects are the result of a specific reprogramming of gene expression. However, the mechanism by which these agents activate the transcription of some genes, such as p21(WAF1), but repress others, such as cyclin D1, is currently un...

Distinct requirements for chromatin assembly in transcriptional repression by thyroid hormone receptor and histone deacetylase.

Histone deacetylase and chromatin assembly contribute to the control of transcription of the Xenopus TRbetaA gene promoter by the heterodimer of Xenopus thyroid hormone receptor and 9-cis retinoic acid receptor (TR-RXR). Addition of the histone deacetylase inhibitor Trichostatin A (TSA) relieves repression of transcription due to chromatin assembly following microinjection of templates into Xen...
