Mitotic antipairing of homologous and sex chromosomes via spatial restriction of two haploid sets. [PDF]
, 2018 Pairing homologous chromosomes is required for recombination. However, in nonmeiotic stages it can lead to detrimental consequences, such as allelic misregulation and genome instability, and is rare in human somatic cells.

Diversity, genetic mapping, and signatures of domestication in the carrot (Daucus carota L.) genome, as revealed by Diversity Arrays Technology (DArT) markers [PDF]
, 2013 Carrot is one of the most economically important vegetables worldwide, but genetic and genomic resources supporting carrot breeding remain limited. We developed a Diversity Arrays Technology (DArT) platform for wild and cultivated carrot and used it to ...

iScience, 2023 Summary: DNA Topoisomerase IIα (TopoIIα) decatenates sister chromatids, allowing their segregation in mitosis. Without the TopoIIα Strand Passage Reaction (SPR), chromosome bridges and ultra-fine DNA bridges (UFBs) arise in anaphase.

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]
, 2019 Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Segregating Chromosomes in the Mammalian Oocyte [PDF]
Current Biology, 2018 Chromosome segregation errors in human oocytes lead to aneuploid embryos that cause infertility and birth defects. Here we provide an overview of the chromosome-segregation process in the mammalian oocyte, highlighting mechanistic differences between oocytes and somatic cells that render oocytes so prone to segregation error.

GSK461364 Inhibits NLRP3 Inflammasome by Targeting NEK7 Phosphorylation
Advanced Science, EarlyView.Schematic diagram of the mechanism by which GSK461364 inhibits NLRP3 inflammasome activation. GSK461364 inhibits the phosphorylation of NEK7 likely at serine 221 and serine 260 by suppressing the activity of PLK1, thereby restraining the formation of the NLRP3 inflammasome.

Nature Communications, 2022 Tension stabilizes properly attached microtubules to kinetochores during chromosome segregation, and lack of tension leads to release. Here the authors show that tension directly suppresses Aurora B kinase mediated destabilization of reconstituted ...
