Heterochromatin: the hidden epigenetic geography of the Y chromosome.
Sir, We read with great interest the systematic review and meta-analysis of Stouffs et al. (2010), which aimed to characterize the association between gr/gr deletions and male infertility. The authors present evidence supporting that the strength of the association depends on the ethnicity and geographic region of the tested population. Such observation is concurrent with our previously publish...
متن کاملRapid evolution of a Y-chromosome heterochromatin protein underlies sex chromosome meiotic drive.
Sex chromosome meiotic drive, the non-Mendelian transmission of sex chromosomes, is the expression of an intragenomic conflict that can have extreme evolutionary consequences. However, the molecular bases of such conflicts remain poorly understood. Here, we show that a young and rapidly evolving X-linked heterochromatin protein 1 (HP1) gene, HP1D2, plays a key role in the classical Paris sex-ra...
متن کاملI-49: Human Y Chromosome ProteomeProject
The success of the Human Genome Project (HGP) has provided a blueprint for the approximately 20,000 gene-encoded proteins potentially active in all of the hundreds of cell types that make up the human body. Yet we still have limited knowledge about a majority of the gene-encoded proteins which are the “building blocks of life” and “cellular machinery”. It is estimated that for nearly half of th...
متن کاملA Distinct Type of Heterochromatin at the Telomeric Region of the Drosophila melanogaster Y Chromosome
Heterochromatin assembly and its associated phenotype, position effect variegation (PEV), provide an informative system to study chromatin structure and genome packaging. In the fruit fly Drosophila melanogaster, the Y chromosome is entirely heterochromatic in all cell types except the male germline; as such, Y chromosome dosage is a potent modifier of PEV. However, neither Y heterochromatin co...
متن کاملPartial and complete microdeletions of Y chromosome in infertile males from South of Iran
Y chromosome microdeletions are the second genetic cause of male infertility. The incidence of Y chromosome microdeletions can vary considerably depending on several factors, including patient selection criteria, population composition, and diagnostic protocols. They are associated with spermatogenic failure and lead to azoospermia or oligozoospermia. The advance in assisted reproductive techno...
