The cytoplasmic fraction of the histone lysine methyltransferase Setdb1 is essential for embryonic stem cells

open access: yesiScience, 2023
Summary: The major lysine methyltransferase (KMT) Setdb1 is essential for self-renewal and viability of mouse embryonic stem cells (mESCs). Setdb1 was primarily known to methylate the lysine 9 of histone 3 (H3K9) in the nucleus, where it regulates ...

Dynamic methylation of histone H3K18 in differentiating Theileria parasites

open access: yesNature Communications, 2021
Post-translational modifications (PTM) of histones are important for epigenetic regulation in mammals. Here, Cheeseman et al. report dynamic changes in H3K18 PTM during the differentiation stages of Theileria parasites and they identify a SET-domain ...

Glucose controls co-translation of structurally related mRNAs via the mTOR and eIF2 pathways in human pancreatic beta cells

open access: yesFrontiers in Endocrinology, 2022
Pancreatic beta cell response to glucose is critical for the maintenance of normoglycemia. A strong transcriptional response was classically described in rodent models but, interestingly, not in human cells.

Imaging the response to DNA damage in heterochromatin domains reveals core principles of heterochromatin maintenance

open access: yesNature Communications, 2021
The heterochromatin compartment is key for genome stability and cell fate transitions. Here, by tracking the heterochromatin response to UV damage in real time, the authors reveal how heterochromatin features are preserved following a genotoxic stress ...

Dissecting regulatory pathways for transcription recovery following DNA damage reveals a non-canonical function of the histone chaperone HIRA

open access: yesNature Communications, 2021
How gene expression reactivation is promoted following DNA damage is not yet clear. Here, the authors identify a role for the human histone chaperone complex HIRA in transcription restart following UV damage independently of its function in new H3.3 ...

Identification of a dinucleotide signature that discriminates coding from non-coding long RNAs

open access: yesFrontiers in Genetics, 2014
To date, the main criterion by which long ncRNAs (lncRNAs) are discriminated from mRNAs is based on the capacity of the transcripts to encode a protein. However, it becomes important to identify non-ORF-based sequence characteristics that can be used to ...

DNA damage triggers squamous metaplasia in human lung and mammary cells via mitotic checkpoints

open access: yesCell Death Discovery, 2023
Epithelial transdifferentiation is frequent in tissue hyperplasia and contributes to disease in various degrees. Squamous metaplasia (SQM) precedes epidermoid lung cancer, an aggressive and frequent malignancy, but it is rare in the epithelium of the ...

Single-cell Visualization of Chromosome Transcriptional Territories by RNA-paint

open access: yesBio-Protocol, 2016
We developed a FISH-based method to directly assess chromosome-wide transcriptional activity, thereby enabling the visualization of the actively transcribed fraction of a chromosome at the single-cell level.

Duox-generated reactive oxygen species activate ATR/Chk1 to induce G2 arrest in Drosophila tracheoblasts

open access: yeseLife, 2021
Progenitors of the thoracic tracheal system of adult Drosophila (tracheoblasts) arrest in G2 during larval life and rekindle a mitotic program subsequently.

A primate-specific retroviral enhancer wires the XACT lncRNA into the core pluripotency network in humans

open access: yesNature Communications, 2019
XACT is a primate-specific TE-derived lncRNA that coats active X chromosomes in pluripotent cells and may contribute to species-specific regulation of X chromosome inactivation.
