Recruitment of Oct4 protein to UV-damaged chromatin in embryonic stem cells. [PDF]

, 2011
BACKGROUND: Oct4 is a specific marker of embryonic stem cell (ESC) pluripotency. However, little is known regarding how Oct4 responds to DNA damage. Here, we investigated whether Oct4 recognizes damaged chromatin in mouse ESCs stably expressing GFP-Oct4.

Subclone-specific microenvironmental impact and drug response in refractory multiple myeloma revealed by single‐cell transcriptomics

Nature Communications, 2021
Virtually all patients with multiple myeloma become unresponsive to treatment over time. Relapsed/refractory multiple myeloma (RRMM) is accompanied by the clonal evolution of myeloma cells with heterogeneous genomic aberrations and profound changes of ...

Erratum: Open chromatin in pluripotency and reprogramming [PDF]

Nature Reviews Molecular Cell Biology, 2011
Nature Reviews Molecular Cell Biology 12, 36–47 (2011) In the reference list for this article, reference 39 was incorrect. The reference should have been “Azuara V. et al. Chromatin signatures of pluripotent cell lines. Nature Cell Biol. 8, 532–538 (2006)”. The authors apologize for this error.

Tethering of CHROMATOR and dCTCF proteins results in decompaction of condensed bands in the Drosophila melanogaster polytene chromosomes but does not affect their transcription and replication timing. [PDF]

PLoS ONE, 2018
Instulator proteins are central to domain organization and gene regulation in the genome. We used ectopic tethering of CHROMATOR (CHRIZ/CHRO) and dCTCF to pre-defined regions of the genome to dissect the influence of these proteins on local chromatin ...

Perturbation of chromatin structure globally affects localization and recruitment of splicing factors [PDF]

, 2012
Chromatin structure is an important factor in the functional coupling between transcription and mRNA processing, not only by regulating alternative splicing events, but also by contributing to exon recognition during constitutive splicing.

Formaldehyde-Assisted Isolation of Regulatory Elements (FAIRE) analysis uncovers broad changes in chromatin structure resulting from hexavalent chromium exposure. [PDF]

PLoS ONE, 2014
The ability of chromatin to switch back and forth from open euchromatin to closed heterochromatin is vital for transcriptional regulation and genomic stability, but its dynamic structure is subject to disruption by exposure to environmental agents such ...

Pluripotency factor opens chromatin [PDF]

Science, 2016
Pluripotency All cells in an organism share the same genome. Differences in form and function arise from cells varying the specific genes they express. Temporal and spatial cues trigger changes in chromatin condensation: An open arrangement supports, whereas a closed conformation blocks, gene expression. Lopes Novo et al.

Damage site chromatin: open or closed? [PDF]

Current Opinion in Cell Biology, 2011
Technical advances in recent years, such as laser microirradiation and chromatin immunoprecipitation, have led to further understanding of DNA damage responses and repair processes as they happen in vivo and have allowed us to better evaluate the activities of new factors at damage sites.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
