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

Project description: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.

TERT rearrangements are frequent in neuroblastoma and identify aggressive tumors

Project description:Whole genome sequencing detected structural rearrangements of TERT in 17/75 high stage neuroblastoma with 5 cases resulting from chromothripsis. Rearrangements were associated with increased TERT expression and targeted immediate up- and down-stream regions of TERT, placing in 7 cases a super-enhancer close to the breakpoints. TERT rearrangements (23%), ATRX deletions (11%) and MYCN amplifications (37%) identify three almost non-overlapping groups of high stage neuroblastoma, each associated with very poor prognosis

Telomerase subunit TERT regulates MYC stability independent of its role on telomeres (array)

Project description:Constitutively active MYC and reactivated telomerase often co-exist in cancers. While the reactivation of telomerase is thought to be essential for replicative immortality, MYC, in conjunction with co-factors, confers several growth advantages to cancer cells. However, it is unclear which co-factors sustain elevated MYC activity in tumors . Here, we identify TERT, the catalytic subunit of telomerase, as a novel regulator of MYC stability in cancers. Binding of TERT to MYC stabilizes its levels on chromatin, contributing to either activation or repression of its target genes. Mechanistically, TERT regulates MYC ubiquitination and stability, and this effect of TERT is independent of its role on telomeres. Genetic inhibition and knocking out of TERT phenocopied the loss of MYC, resulting in reduced disease burden of early- and late-stage MYC-driven murine lymphomas. Conversly, the ectopic expression of TERT could substitute for reduced MYC in these functions. Finally we show that TERT null mice, unlike Terc null mice, show delayed onset of MYC induced lymphomagenesis. Accordingly, inhibiting TERT function in primary human leukemia cells blocked the expression of MYC targets, while Terc depletion had no effects . Based on our data, we conclude that the re-expression of TERT, a direct MYC target in tumors, provides a feed-forward mechanism to potentiate MYC-dependent oncogenesis.

ChIP was performed using anti-MYC (sc-764) in primary lymphoma cells from Eµ-Myc;Tert -/- mice, Eµ-Myc;Tert +/+ mice, or in P493 cells treated with shTert, P493 shTerc and shControl.
