Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Comparative Satellitomics in Arowanas (Telostei, Osteoglossiformes) Sheds Light on the Evolution of Ancient Satellite DNAs

open access: yesIntegrative Zoology, EarlyView.
This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

Determining the role of centromeric long non-coding RNA in chromosome segregation in saccharomyces cerevisiae

open access: yes, 2016
Centromeric DNA sequences are not conserved among organisms and centromeres are proposed to be regulated epigenetically. Centromeric transcription is one of the epigenetic factors identified in many eukaryotes, and increasing evidences indicate that ...

Telangiectasia in Systemic Sclerosis Is a Marker of Increased Disease Morbidity and Mortality: Analyses From the Australian Scleroderma Cohort Study

open access: yesAustralasian Journal of Dermatology, EarlyView.
ABSTRACT This Australian retrospective cohort analysis of 1977 patients investigates and expands on correlates of telangiectasia in systemic sclerosis to determine whether this cutaneous sign is a potential surrogate marker for disease progression and prognosis.

A Centromere Attribute Integration Approach to Centromere Identification

open access: yes, 1996
Automated and nonautomated approaches to chromosome classification involves assessing several chromosome attributes. The centromere is an important attribute which provides insight to other features such as chromosome orientation and the banding pattern ...

Centromere-size reduction and chromatin state dynamics following intergenomic hybridization in cotton.

open access: yesPLoS Genetics
Centromeres are pivotal for accurate chromosome segregation, yet their regulation and evolutionary dynamics remain poorly understood. Here, we investigate centromeres of the diploid species Gossypium anomalum (Ga, B-genome) that were transferred into ...

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Centromere repositioning in mammals

open access: yes, 2012
The evolutionary history of chromosomes can be tracked by the comparative hybridization of large panels of bacterial artificial chromosome clones. This approach has disclosed an unprecedented phenomenon: 'centromere repositioning', that is, the movement ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

open access: yesAndrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.
