Complete or partial loss of the Y chromosome in an unselected cohort of 865 non-vasectomized, azoospermic men

open access: yesBasic and Clinical Andrology, 2023
Background Structural abnormalities as well as minor variations of the Y chromosome may cause disorders of sex differentiation or, more frequently, azoospermia.

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]

open access: yes, 2012
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...

The genetic and cultural impact of the Steppe migration into Europe

open access: yesAnnals of Human Biology, 2021
Background During the early 3rd millennium BCE migration from Pontic Steppe, mainly related to Yamnaya culture, has affected European populations both culturally and genetically, however, it has long been debated to what extent this migration was male ...

The Origins of the Royal Spanish Surname Castilla: Genetics and Genealogy

open access: yesGenealogy, 2023
In most Western European societies, surnames pass from generation to generation and in cases where surnames are shared by fathers to children, the Y chromosome passes down from fathers to male offspring in the same way as surnames do.

Shared and species-specific patterns of nascent Y chromosome evolution in two guppy species [PDF]

open access: yes, 2018
Sex chromosomes form once recombination is halted around the sex-determining locus between a homologous pair of chromosomes, resulting in a male-limited Y chromosome.

De novo transcriptome assembly reveals sex-specific selection acting on evolving neo-sex chromosomes in Drosophila miranda. [PDF]

open access: yes, 2014
BackgroundThe Drosophila miranda neo-sex chromosome system is a useful resource for studying recently evolved sex chromosomes. However, the neo-Y genomic assembly is fragmented due to the accumulation of repetitive sequence.

Y Chromosome

open access: yesEncyclopedic Dictionary of Archaeology, 2019
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies.

PICH deficiency limits the progression of MYC-induced B-cell lymphoma

open access: yesBlood Cancer Journal
Plk1-interacting checkpoint helicase (PICH) is a DNA translocase involved in resolving ultrafine anaphase DNA bridges and, therefore, is important to safeguard chromosome segregation and stability.

The early evolutionary history of neo-sex chromosomes in Neotropical grasshoppers, Boliviacris noroestensis (Orthoptera: Acrididae: Melanoplinae) [PDF]

open access: yes, 2014
Neo-sex chromosomes are an important component of chromosome variation in Orthoptera, particularly South American Melanoplinae species, which have proven to be outstanding experimental model system to study the mechanism of sex chromosome evolution in ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
