Isolation and characterization of spermatogenic cells from cattle, yak and cattleyak

Animal Reproduction Science, 2018
Cattleyak forms the first generation in the cross-breeding of cattle (Bos taurus) and yak (Bos grunniens), the purpose of which is to increase the yak's performance in meat and milk production. The female cattleyak is fertile while the male remains sterile due to spermatogenic arrest.

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.

Molecular characterization and epigenetic regulation of Mei1 in cattle and cattle–yak

Gene, 2015
Mei1 is required for the homologous recombination of meiosis during the mammalian spermatogenesis. However, the knowledge about bovine Mei1 (bMei1) is still limited. In the present study, we cloned and characterized the bMei1, and investigated the epigenetic regulatory mechanism of bMei1 expression in vivo and in vitro. The full length coding region of

Transcriptome analysis reveals dysregulated gene expression networks in Sertoli cells of cattle-yak hybrids

Theriogenology, 2023
Cattle-yak, the hybrid offspring of yak and taurine cattle, exhibits male sterility with normal female fertility. Spermatogenesis is arrested in adult cattle-yak, and apoptosis is elevated in spermatogenic cells. Currently, the mechanisms underlying these defects remain elusive.

Cattle, Yaks, Traction, and the Bronze Age Spread of Pastoralism into the Mongolian Steppe

2022
Cattle traction helped increase crop yields and enhance trade of staple goods among sedentary agricultural communities for millennia, but oxen labor was also important for mobile pastoralists, particularly in Inner Asia where yaks were also herded, and was used to carry materials, portable dwellings, and people.

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 ...

Comparative proteomic analysis identifies differentially expressed proteins associated with meiotic arrest in cattle‐yak hybrids

PROTEOMICS, 2023
AbstractCattle‐yak, the interspecific hybrid between yak and taurine cattle, exhibits male‐specific sterility. Massive loss of spermatogenic cells, especially spermatocytes, results in azoospermia in these animals. Currently, the mechanisms underlying meiosis block and defects in spermatocyte development remain elusive.

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.

Aberrant levels of DNA methylation and H3K9 acetylation in the testicular cells of crossbred cattle–yak showing infertility

Reproduction in Domestic Animals, 2021
AbstractAlthough the interspecies hybridization of bovids, such as cattle–yak (Bos taurus × Bos grunniens), has heterosis benefits, the infertility of hybrid males affects the maintenance of dominant traits in subsequent generations. To achieve reproductive capacity, male germ cell development requires coordinated changes in gene expression, including ...

[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
