ETAA1 ensures proper chromosome segregation: A matter of S phase or mitosis? [PDF]

, 2019
ETAA1 activates the master checkpoint kinase ATR. Bass and Cortez (2019. J. Cell Biol. https://doi.org/10.1083/jcb.201810058) recently reported an intra-mitotic function of ETAA1 that safeguards chromosome stability.

Growth of donor-derived dendritic cells from the bone marrow of murine liver auograft recipients in response to granulocyte/macrophage colony-stimulating factor [PDF]

, 1995
Allografts of the liver, which has a comparatively heavy leukocyte content compared with other vascularized organs, are accepted permanently across major histocompatibility complex barriers in many murine strain combinations without immunosuppressive ...

Effects of sex chromosome dosage on corpus callosum morphology in supernumerary sex chromosome aneuploidies. [PDF]

, 2014
BackgroundSupernumerary sex chromosome aneuploidies (sSCA) are characterized by the presence of one or more additional sex chromosomes in an individual's karyotype; they affect around 1 in 400 individuals.

The Y chromosome

Reproductive BioMedicine Online, 2002
The Y chromosome has evolved to provide sex determination in mammals. In association with its evolution, genes important for spermatogenesis have been sequestered on this chromosome. Further, X chromosome inactivation has developed as a mechanism to prevent over-expression of genetic factors important for somatic function in females, with maintenance ...

Molecular cytogenetics (FISH, GISH) of Coccinia grandis: A ca. 3 myr-old species of Cucurbitaceae with the largest Y/autosome divergence in flowering plants [PDF]

, 2013
The independent evolution of heteromorphic sex chromosomes in 19 species from 4 families of flowering plants permits studying X/Y divergence after the initial recombination suppression.

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

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

, 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 ...

Hexavalents in spermatocytes of Robertsonian heterozygotes between Mus m. domesticus 2n 26 from the Vulcano and Lipari Islands (Aeolian Archipelago, Italy) [PDF]

, 2018
The size and shape of the chromosomes, as well as the chromosomal domains that compose them, are determinants in the distribution and interaction between the bivalents within the nucleus of spermatocytes in prophase I of meiosis.

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]

, 2020
The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

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

, 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.
