Transcription–Replication Coordination

open access: yesLife, 2022
Transcription and replication are the two most essential processes that a cell does with its DNA: they allow cells to express the genomic content that is required for their functions and to create a perfect copy of this genomic information to pass on to ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Structure of the measles virus ternary polymerase complex

open access: yesNature Communications
Measles virus (MeV) is a highly contagious pathogen that causes significant morbidity worldwide. Its polymerase machinery, composed of the large protein (L) and phosphoprotein (P), is crucial for viral replication and transcription, making it a promising

Styles of Transcription in Ethnomusicology [PDF]

open access: yes, 1996
Transcription has to do with the writing of musical sounds. In the field of ethnomusicology, transcription has long been considered as an important skill which should lead the ethnomusicologist toward the analysis of folk music, non-Western art music and

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Elongator protein 3b negatively regulates ribosomal DNA transcription in african trypanosomes. [PDF]

open access: yes, 2011
Eukaryotic cells limit ribosomal DNA (rDNA) transcription by RNA polymerase I (RNAP-I) to maintain genome integrity. African trypanosomes present an excellent model for studies on RNAP-I regulation because they possess a bifunctional RNAP-I and because ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Dynamic partitioning of a critical elongation factor between LEC and SEC regulates cellular snRNA and proliferation-related mRNA transcription

open access: yesNature Communications
Human RNA polymerase II (Pol II) regulates transcription of significant number of snRNA and proliferation-related mRNA genes by involving Little Elongation Complex (LEC) and Super Elongation Complex (SEC) respectively.

Fetal Muse-based therapy prevents lethal radio-induced gastrointestinal syndrome by intestinal regeneration

open access: yesStem Cell Research & Therapy, 2023
Background Human multilineage-differentiating stress enduring (Muse) cells are nontumorigenic endogenous pluripotent-like stem cells that can be easily obtained from various adult or fetal tissues.
