COMMENT ON “A PARTIAL TRISOMY 9 CASE WITH DICENTRIC CHROMOSOME DUE TO THE ADJACENT-2 SEGREGATION OF MATERNAL RECIPROCAL TRANSLOCATION”

İstanbul Tıp Fakültesi Dergisi
Dear Editor, We have read the article entitled “A partial trisomy 9 case with dicentric chromosome due to the adjacent-2 segregation of maternal reciprocal translocation” by Urtekin et al.

Methylated histones on mitotic chromosomes promote topoisomerase IIα function for high fidelity chromosome segregation

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.

Coordination of Chromosome Segregation and Cell Division in Staphylococcus aureus

Frontiers in Microbiology, 2017
Productive bacterial cell division and survival of progeny requires tight coordination between chromosome segregation and cell division to ensure equal partitioning of DNA.

Kinetochore-independent chromosome segregation driven by lateral microtubule bundles

eLife, 2015
During cell division, chromosomes attach to spindle microtubules at sites called kinetochores, and force generated at the kinetochore-microtubule interface is the main driver of chromosome movement.

Adaptive Resistance to an Inhibitor of Chromosomal Instability in Human Cancer Cells

Cell Reports, 2016
Karyotype diversity is a hallmark of solid tumors that contributes to intratumor heterogeneity. This diversity is generated by persistent chromosome mis-segregation associated with chromosomal instability (CIN).

Motorized Chromosome Models of Mitosis [PDF]

arXiv
During mitosis, near-spherical chromosomes reconfigure into rod-like structures to ensure their accurate segregation to daughter cells. We explore here, the interplay between the nonequilibrium activity of molecular motors in determining the chromosomal organization in mitosis and its characteristic symmetry-breaking events.

Ancestral inference from haplotypes and mutations [PDF]

arXiv, 2017
We consider inference about the history of a sample of DNA sequences, conditional upon the haplotype counts and the number of segregating sites observed at the present time. After deriving some theoretical results in the coalescent setting, we implement rejection sampling and importance sampling schemes to perform the inference. The importance sampling
