Bivalent individualization during chromosome territory formation in Drosophila spermatocytes by controlled condensin II protein activity and additional force generators.

PLoS Genetics, 2021
Reduction of genome ploidy from diploid to haploid necessitates stable pairing of homologous chromosomes into bivalents before the start of the first meiotic division.

M-FISH analysis shows that complex chromosome aberrations induced by α-particle tracks are cumulative products of localised rearrangements [PDF]

, 2002
Complex chromosome aberrations are characteristically induced after exposure to low doses of densely ionising radiation, but little is understood about their formation. To address this, we irradiated human peripheral blood lymphocytes (PBL) in vitro with

Complementarity of Long‐Reads and Optical Mapping in Parkinson's Disease for Structural Variants

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Long‐read sequencing and optical genome mapping technologies have the ability to detect large and complex structural variants. This has led to the discovery of novel pathogenic variants in neurodegenerative movement disorders. Thus, we aimed to systematically compare the SV detection capabilities of OGM and ONT in Parkinson's disease.

Genome-wide high-resolution mapping of UV-induced mitotic recombination events in Saccharomyces cerevisiae. [PDF]

, 2013
In the yeast Saccharomyces cerevisiae and most other eukaryotes, mitotic recombination is important for the repair of double-stranded DNA breaks (DSBs). Mitotic recombination between homologous chromosomes can result in loss of heterozygosity (LOH).

Common Signatures of Altered Gene Regulation and Invasiveness of Different Breast Cancer Cell Lines after Matrix Interface Crossing

Advanced Healthcare Materials, EarlyView.
Interface transmigration reprograms triple‐negative breast cancer cells, triggering a shared switch toward more aggressive and invasive phenotypes. Using a collagen I interface model, this study identifies shared transcriptional changes involving proliferation, chromatin remodeling, and DNA repair pathways.

Reducing MSH4 copy number prevents meiotic crossovers between non-homologous chromosomes in Brassica napus

Nature Communications, 2019
Non-homologous crossovers impair correct chromosome segregation in allopolyploids. Here the authors show that most non-homologous crossovers in Brassica napus arise from MSH4-dependent recombination and provide evidence that post-polyploidization ...

Measuring Homologous Recombination Rates between Chromosomal Locations in Salmonella

Bio-Protocol, 2019
Homologous recombination between two similar DNA molecules, plays an important role in the repair of double-stranded DNA breaks. Recombination can occur between two sister chromosomes, or between two locations of similar sequence identity within the same

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

Advanced Science, EarlyView.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...
