Single-cell analysis identifies critical regulators of spermatogonial development and differentiation in cattle-yak bulls

open access: yesJournal of Dairy Science
: Spermatogenesis is a continuous process in which functional sperm are produced through a series of mitotic and meiotic divisions and morphological changes in germ cells.

N6-Methyladenosine Modification-Related Genes Express Differentially in Sterile Male Cattle-Yaks

open access: yesLife
N6-methyladenosine (m6A), an RNA post-transcriptional modification, plays a crucial role in spermatogenesis. Cattle-yaks are interspecific hybrid offsprings of yak and cattle, and male cattle-yaks are sterile.

Full-length transcriptome sequencing of the longissimus dorsi muscle of yak and cattle-yak using nanopore technology

open access: yesInternational Journal of Biological Macromolecules
Short-read RNA sequencing has been used to sequence the transcriptome of the skeletal muscle of yak and cattle-yak; however, full-length transcripts cannot be obtained and alternative splicing (AS) events cannot be inferred using this sequencing approach.

Heat shock protein 60 expression and localisation in different tissues and testis development of male cattle (cattle-yak and yak)

open access: yesFolia Morphologica, 2021
BACKGROUND: Heat shock protein 60 (Hsp60) play important roles in protecting testicular development and production of sperms. This study was conducted to investigate Hsp60 gene expression and localisation in testicular development to ascertain its ...

Comparative study on the distribution and expression of Neuroglobin and Hypoxia-inducible factor-1α in the telencephalon of yak and cattle

open access: yesBrazilian Journal of Biology, 2021
The telencephalon refers to the most highly developed and anterior part of the forebrain, consisting mainly of the cerebral hemispheres. The study determined Neuroglobin (Ngb) and Hypoxia-inducible factor (HIF-1α) expression in the telencephalon of yak ...

Comparative Transcriptome Analysis of Spermatogenesis Arrest in Cattle-Yak [PDF]

open access: yesSCIENTIA SINICA Vitae, 2014
The male infertility of cattle-yak, which is the hybrid offspring of cattle and yak, is a difficult problem for cross-breeding and improvement of yak. In this study, we used high-throughput sequencing technology to obtain the transcriptomes of the testicular tissues of both cattle-yak and yak, and investigated the expression profiles of the genes ...

Male hybrid sterility in the cattle-yak and other bovines: a review

open access: yesBiology of Reproduction, 2020
Abstract Hybridization is important for both animal breeders attempting to fix new phenotypic traits and researchers trying to unravel the mechanism of reproductive barriers in hybrid species and the process of speciation. In interspecies animal hybrids, gains made in terms of adaptation to environmental conditions and hybrid vigor may ...

Yak rumen microbiome elevates fiber degradation ability and alters rumen fermentation pattern to increase feed efficiency

open access: yesAnimal Nutrition, 2022
Rumen microbes play an important role in ruminant energy supply and animal performance. Previous studies showed that yak (Bos grunniens) rumen microbiome and fermentation differ from other ruminants.

The Biological Characteristics and Differential Expression Patterns of TSSK1B Gene in Yak and Its Infertile Hybrid Offspring

open access: yesAnimals, 2023
This study aimed to investigate the spatially and temporally expressed patterns and biological characteristics of TSSK1B in male yaks and explore the potential correlation between TSSK1B and male sterility of the yak hybrid offspring (termed cattle–yak).

Forage lignocellulose is an important factor in driving the seasonal dynamics of rumen anaerobic fungi in grazing yak and cattle

open access: yesMicrobiology Spectrum, 2023
Anaerobic fungi (AF) inhabit the gastrointestinal tract of ruminants and play an important role in the degradation of fiber feed. However, limited knowledge is available on seasonal dynamics and inter-species differences in rumen AF community in yak and ...
