Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

open access: yesAdvanced Science, EarlyView.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

Agouti C57BL/6N embryonic stem cells for mouse genetic resources. [PDF]

open access: yes, 2009
We report the characterization of a highly germline competent C57BL/6N mouse embryonic stem cell line, JM8. To simplify breeding schemes, the dominant agouti coat color gene was restored in JM8 cells by targeted repair of the C57BL/6 nonagouti mutation ...

Epigenetic reactivation of LINE‐1 retrotransposon disrupts NuRD corepressor functions and induces oncogenic transformation in human bronchial epithelial cells

open access: yesMolecular Oncology, 2018
Long interspersed nuclear element‐1 (LINE‐1 or L1) reactivation is linked to poor prognosis in non‐small‐cell lung carcinoma (NSCLC), but the molecular bases of this response remain largely unknown.

Adaptive evolution of an essential telomere protein restricts telomeric retrotransposons

open access: yeseLife, 2020
Essential, conserved cellular processes depend not only on essential, strictly conserved proteins but also on essential proteins that evolve rapidly. To probe this poorly understood paradox, we exploited the rapidly evolving Drosophila telomere-binding ...

Virophages and retrotransposons colonize the genomes of a heterotrophic flagellate

open access: yeseLife, 2021
Virophages can parasitize giant DNA viruses and may provide adaptive anti-giant virus defense in unicellular eukaryotes. Under laboratory conditions, the virophage mavirus integrates into the nuclear genome of the marine flagellate Cafeteria burkhardae ...

Ingrowth by photoreceptor axons induces transcription of a retrotransposon in the developing Drosophila brain [PDF]

open access: yes, 1994
The development of the lamina, the first optic ganglion of the fly visual system, depends on inductive cues from the innervating photoreceptor axons. lacZ expression from a P-element insertion, A72, occurs in the anlage of the lamina coincident with axon

Genome-wide analysis of LTR-retrotransposon diversity and its impact on the evolution of the genus Helianthus (L.)

open access: yesBMC Genomics, 2017
Genome divergence by mobile elements activity and recombination is a continuous process that plays a key role in the evolution of species. Nevertheless, knowledge on retrotransposon-related variability among species belonging to the same genus is still ...

Retrotransposon Domain Swapping [PDF]

open access: yesThe Plant Cell, 2010
Whether you consider them major genomic parasites or potentially major drivers of genome expansion, long terminal repeat (LTR) retrotransposons are major, making up 15 to 90% of plant nuclear genomes (reviewed in Sabot and Schulman, 2006). These elements transpose by a replicate-and-paste mechanism, wherein an RNA copy of the retrotransposon is reverse

Widespread horizontal transfer of retrotransposons [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
In higher organisms such as vertebrates, it is generally believed that lateral transfer of genetic information does not readily occur, with the exception of retroviral infection. However, horizontal transfer (HT) of protein coding repetitive elements is the simplest way to explain the patchy distribution of BovB, a long interspersed element (LINE ...

Change and HOAP for the best

open access: yeseLife, 2020
HOAP is a telomere-binding protein that has a conserved role in Drosophila, but it also needs to evolve quickly to restrict telomeric retrotransposons.
