The asparagus genome sheds light on the origin and evolution of a young Y chromosome

open access: yesNature Communications, 2017
Sex chromosomes evolved from autosomes many times across the eukaryote phylogeny. Several models have been proposed to explain this transition, some involving male and female sterility mutations linked in a region of suppressed recombination between X ...

An azoospermic factor gene, Ddx3y and its paralog, Ddx3x are dispensable in germ cells for male fertility

open access: yesThe Journal of Reproduction and Development, 2019
About 10% of male infertile patients show abnormalities in spermatogenesis. The microdeletion of azoospermia factor a (AZFa) region of the Y chromosome is thought to be a cause of spermatogenic failure.

Detection of skewed X-chromosome inactivation in Fragile X syndrome and X chromosome aneuploidy using quantitative melt analysis. [PDF]

open access: yes, 2015
Methylation of the fragile X mental retardation 1 (FMR1) exon 1/intron 1 boundary positioned fragile X related epigenetic element 2 (FREE2), reveals skewed X-chromosome inactivation (XCI) in fragile X syndrome full mutation (FM: CGG > 200) females ...

The IQ‐compete assay for measuring mitochondrial protein import efficiencies in living yeast cells

open access: yesFEBS Letters, EarlyView.
The efficiency of mitochondrial protein import depends on the properties of the newly synthesized precursor proteins. The Import and de‐Quenching Competition (IQ‐compete) assay is a novel method to monitor the import efficiency of different proteins by fluorescence in living yeast cells.

The study of human Y chromosome variation through ancient DNA

open access: yesHuman Genetics, 2017
High throughput sequencing methods have completely transformed the study of human Y chromosome variation by offering a genome-scale view on genetic variation retrieved from ancient human remains in context of a growing number of high coverage whole Y ...

A new robust diagnostic polymerase chain reaction for determining the mating status of female Anopheles gambiae mosquitoes. [PDF]

open access: yes, 2007
The principal malaria vector in Africa, Anopheles gambiae, contains two pairs of autosomes and one pair of sex chromosomes. The Y chromosome is only associated with males and other Y chromosome-specific DNA sequences, which are transferred to women ...

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

The Drosophila Y Chromosome Affects Heterochromatin Integrity Genome-Wide

open access: yesbioRxiv, 2017
The Drosophila Y-chromosome is gene poor and mainly consists of silenced, repetitive DNA. Nonetheless, the Y influences expression of hundreds of genes genome-wide, possibly by sequestering key components of the heterochromatin machinery away from other ...

Populations of Transcarpathia and Bukovina on the genetic landscape of surrounding regions

open access: yesRegulatory Mechanisms in Biosystems, 2015
The territory of present-day Ukraine is subdivided into some regions with specific demographic and politic history. Nevertheless, the corresponding subdivision in genetic structure is not revealed in previous investigations: populations of Ukrainians ...

Ten years of the horse reference genome: insights into equine biology, domestication and population dynamics in the post-genome era. [PDF]

open access: yes, 2019
The horse reference genome from the Thoroughbred mare Twilight has been available for a decade and, together with advances in genomics technologies, has led to unparalleled developments in equine genomics.
