Present Y chromosomes support the Persian ancestry of Sayyid Ajjal Shams al-Din Omar and Eminent Navigator Zheng He [PDF]

arXiv, 2013
Sayyid Ajjal is the ancestor of many Muslims in areas all across China. And one of his descendants is the famous Navigator of Ming Dynasty, Zheng He, who led the largest armada in the world of 15th century. The origin of Sayyid Ajjal's family remains unclear although many studies have been done on this topic of Muslim history. In this paper, we studied

Tumor clusters with divergent inflammation and human retroelement expression determine the clinical outcome of patients with serous ovarian cancer

Molecular Oncology, EarlyView.
Analysis of treatment‐naïve high‐grade serous ovarian carcinoma (HGSOC) and control tissues for ERVs, LINE‐1 (L1), inflammation, and immune checkpoints identified five clusters with diverse patient recurrence‐free survivals. An inflammation score was calculated and correlated with retroelement expression, where one novel cluster (Triple‐I) with high ...

The longevity of Y chromosomes: The Human Y chromosome is not dead (yet) [PDF]

Heredity, 2006
There are those who want us to believe that, given sufficient time, the human Y-chromosome (HY) will disappear (Graves, 2006). Their reasoning is simple and straightforward. Owing to lack of recombination the HY has degenerated in size and number of genes during its 300 million years of splendid isolation and there is nothing to prevent this process ...

The slowdown of Y chromosome expansion in dioecious Silene latifolia due to DNA loss and male-specific silencing of retrotransposons

BMC Genomics, 2018
Background The rise and fall of the Y chromosome was demonstrated in animals but plants often possess the large evolutionarily young Y chromosome that is thought has expanded recently.

YFitter: Maximum likelihood assignment of Y chromosome haplogroups from low-coverage sequence data [PDF]

arXiv, 2014
Low-coverage short-read resequencing experiments have the potential to expand our understanding of Y chromosome haplogroups. However, the uncertainty associated with these experiments mean that haplogroups must be assigned probabilistically to avoid false inferences.

The role of chromosomal rearrangements in the evolution of Silene latifolia sex chromosomes [PDF]

, 2018
Silene latifolia is a model plant for studies of the early steps of sex chromosome evolution. In comparison to mammalian sex chromosomes that evolved 300mya, sex chromosomes of S. latifolia appeared approximately 20mya.

Convergent recombination suppression suggests role of sexual selection in guppy sex chromosome formation. [PDF]

, 2017
Sex chromosomes evolve once recombination is halted between a homologous pair of chromosomes. The dominant model of sex chromosome evolution posits that recombination is suppressed between emerging X and Y chromosomes in order to resolve sexual conflict.

A DIA‐MS‐based proteomics approach to find potential serum prognostic biomarkers in glioblastoma patients

Molecular Oncology, EarlyView.
A DIA‐MS‐based proteomics analysis of serum samples from GB patients and healthy controls showed that high levels of IL1R2 and low levels of CRTAC1 and HRG in serum are associated with poor survival outcomes for GB patients. These circulating proteins could serve as biomarkers for the prediction of outcome in patients with GB.

Human Y chromosome azoospermia factors (AZF) mapped to different subregions in Yq11.

Human Molecular Genetics, 1996
In a large collaborative screening project, 370 men with idiopathic azoospermia or severe oligozoospermia were analysed for deletions of 76 DNA loci in Yq11.
