The expression of histone methyltransferases and distribution of selected histone methylations in testes of yak and cattle-yak hybrid

Theriogenology, 2020
Interspecies hybridization exists widely in nature and plays an important role in animal evolution and adaptation. It is commonly recognized that male offspring of interspecies hybrid are often sterile, which presents a crucial way of reproductive isolation. Currently, the mechanisms underlying interspecies hybrid male sterility are not well understood.

[Expression levels of Cdc2 and Cdc25A mRNA in cattle, yak, and cattle-yak testis].

Yi chuan = Hereditas, 2009
The infertility of cattle-yak, which is the hybrid offspring of cattle and yak, is a difficult problem in crossbreeding and improvement of yak. Cdc2 and Cdc25A are the key genes of meiosis. The decline of their expression levels will cause the spermatogenesis failure and lead to infertility. Therefore, this study was conducted to study the relationship

Histological evaluation and Prdm9 expression level in the testis of sterile male cattle-yaks

Livestock Science, 2014
Abstract The main objective of the present study was to reveal whether the histological structure of testis and the Prdm9 (PR domain containing 9) mRNA level in testis of hybrid sterile yak (i.e. cattle-yaks) differed from that of normal adult yak ( Bos grunniens ).

Molecular cloning, gene expression and methylation status analysis of PIWIL1 in cattle-yaks and the parental generation

Animal Reproduction Science, 2013
The PIWI-like protein 1 (PIWIL1) plays an important role in spermatogenesis and transposon control. In mammals, the absence of the PIWIL1 gene can lead to over-expression of retrotransposons, spermatogenetic arrest, and male infertility. To assess whether the PIWIL1 gene is associated with the male sterility of cattle-yaks, we examined PIWIL1 and LINE ...

Regulation by Hsp27/P53 in testis development and sperm apoptosis of male cattle (cattle‐yak and yak)

Journal of Cellular Physiology, 2018
Heat shock protein 27 (Hsp27)/protein 53 (P53) plays an important role in testis development and spermatozoa regulation, but the relationship between Hsp27/P53 and infertility in cattle is unclear. Here, we focus on male cattle‐yak and yak to investigate the expression and localization of Hsp27/P53 in testis tissues and to explore ...

Differential mRNA Expression and Promoter Methylation Status of SYCP3 Gene in Testes of Yaks and Cattle‐Yaks

Reproduction in Domestic Animals, 2011
ContentsSynaptonemal complex protein 3 (SYCP3) is a DNA‐binding protein located on the lateral elements of the synaptonemal complex. This protein plays an important role in homologous chromosome pairing and is necessary for male meiosis of spermatogenesis.

Proteomics-based study for evaluation crossbreeding advantages of cattle-yak milk

Food Chemistry
Cattle-yaks are increasingly cultivated to boost yak dairy production while reports claim that will decrease the nutritional value of yak milk. However, studies on protein composition differences, especially functional proteins, between yak and cattle-yak milk are limited.

Comparative analysis on mRNA expression level and methylation status of DAZL gene between cattle-yaks and their parents

Animal Reproduction Science, 2011
The autosomal gene Deleted in Azoospermia Like (DAZL) is essential for spermatogenesis. The absence of DAZL gene will lead to meiotic arrest, spermatogenetic failure and male infertility, and so it was usually considered as a candidate gene for male infertility in cattle-yaks.

Effect of glycolysis on water holding capacity during postmortem aging of Jersey cattle‐yak meat

Journal of the Science of Food and Agriculture
AbstractBACKGROUNDPostmortem muscle moisture loss leads to a decrease in carcass weight and can adversely impact overall meat quality. Therefore, it is critical to investigate water holding capacity (WHC) to enhance meat quality. Current research has primarily focused on examining the correlation between signaling molecules and meat quality in relation
