Deep-coverage whole genome sequences and blood lipids among 16,324 individuals. [PDF]

open access: yes, 2018
Large-scale deep-coverage whole-genome sequencing (WGS) is now feasible and offers potential advantages for locus discovery. We perform WGS in 16,324 participants from four ancestries at mean depth >29X and analyze genotypes with four quantitative ...

Genetic determinants of co-accessible chromatin regions in activated T cells across humans. [PDF]

open access: yes, 2018
Over 90% of genetic variants associated with complex human traits map to non-coding regions, but little is understood about how they modulate gene regulation in health and disease.

Chromatin accessibility, not 5mC methylation covaries with partial dosage compensation in crows.

open access: yesPLoS Genetics, 2023
The evolution of genetic sex determination is often accompanied by degradation of the sex-limited chromosome. Male heterogametic systems have evolved convergent, epigenetic mechanisms restoring the resulting imbalance in gene dosage between diploid ...

Major transcriptome re-organisation and abrupt changes in signalling, cell cycle and chromatin regulation at neural differentiation in vivo [PDF]

open access: yes, 2014
Here, we exploit the spatial separation of temporal events of neural differentiation in the elongating chick body axis to provide the first analysis of transcriptome change in progressively more differentiated neural cell populations in vivo.

ATAC-seq and RNA-seq analysis unravel the mechanism of sex differentiation and infertility in sex reversal chicken

open access: yesEpigenetics & Chromatin, 2023
Background Sex determination and differentiation are complex and delicate processes. In female chickens, the process of sex differentiation is sensitive and prone to be affected by the administration of aromatase inhibitors, which result in chicken sex ...

Sex Chromatin and Nuclear Sexing in Birds

open access: yesCYTOLOGIA, 1970
The present study deals with the incidence and distribution of sex chromatin body, drumstick and sessile bodies in two pairs, each of Gallus domesticus, Columba livia and Passer domesticus. Somatic tissues, i.e. liver, duodenum, skin and blood from both sexes were examined.

Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae) [PDF]

open access: yes, 2006
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of Antiteuchus mixtus, A. sepulcralis and

UBQLN4 Represses Homologous Recombination and Is Overexpressed in Aggressive Tumors [PDF]

open access: yes, 2020
Genomic instability can be a hallmark of both human genetic disease and cancer. We identify a deleterious UBQLN4 mutation in families with an autosomal recessive syndrome reminiscent of genome instability disorders.

DNA methylation and DNA methyltransferases [PDF]

open access: yes, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding ...
