Deregulated enhancer‐promoter communication in cancer through altered nuclear architecture

open access: yesInternational Journal of Cancer, EarlyView.
Abstract Enhancers are critical regulators of gene expression. Structural variations in cancer genomes can lead to enhancer hijacking, where oncogenes are activated by mistargeted enhancer activity. Novel enhancer‐promoter interactions may also arise through chromosomal rearrangements that create extrachromosomal DNA elements.

Constitutive centromere-associated network controls centromere drift in vertebrate cells

open access: yesJournal of Cell Biology, 2017
Centromeres are specified by sequence-independent epigenetic mechanisms, and the centromere position may drift at each cell cycle, but once this position is specified, it may not be frequently moved.

T2T genome, pan‐genome analysis, and heat stress response genes in Rhododendron species

open access: yesiMeta, EarlyView.
This study reports the first high‐quality telomere‐to‐telomere (T2T) Rhododendron liliiflorum genome with 11 chromosomes that are gap free. The 24 telomeres and all 13 centromeres detected in this genome, which reached the highest quality gold level.

The kinetochore prevents centromere-proximal crossover recombination during meiosis

open access: yeseLife, 2015
During meiosis, crossover recombination is essential to link homologous chromosomes and drive faithful chromosome segregation. Crossover recombination is non-random across the genome, and centromere-proximal crossovers are associated with an increased ...

Centromere assembly requires selective recognition of centromeric chromatin by centromere protein N

open access: yesThe FASEB Journal, 2008
The kinetochore is a unique chromosomal locus that binds to the mitotic spindle so that chromosomes can segregate in mitosis. Kinetochore assembly requires the specialized chromatin of the centromere that is distinguished by the replacement of histone H3 with the histone H3‐variant centromere protein A (CENP‐A). CENP‐A is thought to epigenetically mark

Two telomere‐to‐telomere pig genome assemblies and pan‐genome analyses provide insights into genomic structural landscape and genetic adaptations

open access: yesiMeta, EarlyView.
This study presented two high‐precision telomere‐to‐telomere genome assemblies for Min and Rongchang pigs, including a detailed exploration of the telomeric and centromeric regions. By integrating pan‐genome and multi‐omics analyses, structural variations linked to genetic adaptation were identified, providing a valuable resource for advancing pig ...
