Chromosomal instability in near-diploid colorectal cancer: a link between numbers and structure. [PDF]

PLoS ONE, 2008
Chromosomal instability (CIN) plays a crucial role in tumor development and occurs mainly as the consequence of either missegregation of normal chromosomes (MSG) or structural rearrangement (SR).

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Bacteria can maintain rRNA operons solely on plasmids for hundreds of millions of years

Nature Communications, 2023
It is generally assumed that all bacteria must have at least one rRNA operon (rrn operon) on the chromosome, but some strains of the genera Aureimonas and Oecophyllibacter carry their sole rrn operon on a plasmid.

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

Investigating the evolutionary dynamics of diploid number variation in Ctenomys (Ctenomyidae, Rodentia) [PDF]

Genetics and Molecular Biology
Contrary to predictions from classical hybrid sterility models of chromosomal speciation, some organisms display high rates of karyotype variation. Ctenomys are the current mammals with the greatest interspecific and intraspecific chromosomal variation ...

Clinical significance of chromosomal integrity in gastric cancers

The International Journal of Biological Markers, 2022
Background A whole-exome or targeted cancer genes panel by next-generation sequencing has been used widely in assisting individualized treatment decisions. Currently, multiple algorithms are developed to estimate DNA copy numbers based on sequencing data,
