A new topology of the human Y chromosome haplogroup E1b1 (E-P2) revealed through the use of newly characterized binary polymorphisms. [PDF]

open access: yesPLoS ONE, 2011
Haplogroup E1b1, defined by the marker P2, is the most represented human Y chromosome haplogroup in Africa. A phylogenetic tree showing the internal structure of this haplogroup was published in 2008.

Unique profile of ordered arrangements of repetitive elements in the C57BL/6J mouse genome implicating their functional roles. [PDF]

open access: yesPLoS ONE, 2012
The entirety of all protein coding sequences is reported to represent a small fraction (~2%) of the mouse and human genomes; the vast majority of the rest of the genome is presumed to be repetitive elements (REs).

Divergent Human Y-Chromosome Microsatellite Evolution Rates [PDF]

open access: yesJournal of Molecular Evolution, 1999
In this work, we analyze several characteristics influencing the low variability of the microsatellite DYS19 in the major founder Amerindian Y chromosome lineage containing the point mutation DYS199-T. Variation of DYS19 was compared with that of five other Y-linked tetranucleotide repeat loci (DYS389A, DYS389B, DYS390, DYS391, and DYS393) in the ...

Mitotic metaphase karyotype of the mosquito Anopheles arabiensis Patton (Diptera: Culicidae) from Kassala State, eastern Sudan

open access: yesCaryologia, 2023
The mosquito Anopheles arabiensis Patton is the most important malaria vector in Sudan. The study was conducted for the first time to describe numerically the karyotype of An. arabiensis from Kassala State, eastern Sudan. Adults An.

Roles of the Y chromosome genes in human cancers

open access: yesAsian Journal of Andrology, 2015
Male and female differ genetically by their respective sex chromosome composition, that is, XY as male and XX as female. Although both X and Y chromosomes evolved from the same ancestor pair of autosomes, the Y chromosome harbors male-specific genes ...

Human Evolution: Y-chromosome clues to human ancestry [PDF]

open access: yesCurrent Biology, 1995
The case for a recent expansion of modern humans from Africa has been strengthened by the finding of monomorphism in part of a Y-linked gene, consistent with the low variability seen in human mitochondrial DNAs.

Stable and robust Xi and Y transcriptomes drive cell-type-specific autosomal and Xa responses in vivo and in vitro in four human cell types

open access: yesCell Genomics
Summary: Recent in vitro studies of human sex chromosome aneuploidy showed that the Xi (“inactive” X) and Y chromosomes broadly modulate autosomal and Xa (“active” X) gene expression. We tested these findings in vivo.

Evolutionary dynamics of the human pseudoautosomal regions.

open access: yesPLoS Genetics, 2021
Recombination between the X and Y human sex chromosomes is limited to the two pseudoautosomal regions (PARs) that present quite distinct evolutionary origins.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
