HDAC inhibition suppresses telomerase activity in neuroblastoma cells harboring TERT rearrangements [array]

ABSTRACT: Genome wide DNA methylation profiling of high-risk TERT-rearranged neuroblastoma cells treated with solvent or HDAC inhibitor panobinostat. The Illumina HumanMethylation EPIC Beadchip was used to obtain DNA methylation profiles. Samples included 3 solvent treated samples and 3 panobinostat-treated samples after 18 h of treatment.

HDAC inhibition suppresses telomerase activity in neuroblastoma cells harboring TERT rearrangements [ChIP-Seq]

Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. The three histone marks acetylation of histone 3 at lysine residue 27 (H3K27ac), trimethylation of histone 3 at lysine residue 4 (H3K4me3) and trimethylation of histone 3 at lysine residue 36 (H3K36me3) were selected, representing marks for an open chromatin structure and enable gene transcription. The two histone marks standing for a condensed chromatin state and disabled gene transcription trimethylation of histone 3 at lysine residue 27 (H3K27me3) and trimethylation of histone 3 at lysine residue 9 (H3K9me3) were chosen. ChIP sequencing of the five histone marks was investigated in high-risk TERT-rearranged neuroblastoma GI-ME-N cells treated with solvent or HDAC inhibitor panobinostat. Exemplary samples include solvent-treated and panobinostat-treated samples after 18 h of treatment.
