Genomic structural variation contributes to evolved changes in gene expression in high-altitude Tibetan sheep

Proceedings of the National Academy of Sciences of the United States of America
Significance Important questions in evolutionary biology concern the relative contributions of different sources of adaptive genetic variation. A related question is whether the contributions of different sources of genetic variation depend on the ...

Detecting signatures of selection within the Tibetan sheep mitochondrial genome

Mitochondrial DNA Part A, 2016
Tibetan sheep, a Chinese indigenous breed, are mainly distributed in plateau and mountain-valley areas at a terrestrial elevation between 2260 and 4100 m. The herd is genetically distinct from the other domestic sheep and undergoes acclimatization to adapt to the hypoxic environment.

The regulatory role of BMP4 in testicular Sertoli cells of Tibetan sheep

Journal of Animal Science, 2022
Abstract This study aimed to determine the regulatory mechanism of bone morphogenetic protein 4 (BMP4) gene in the testes of Tibetan sheep and its role in the blood–testis barrier (BTB). First, we cloned BMP4 gene for bioinformatics analysis, and detected the mRNA and protein expression levels of BMP4 in the testes of Tibetan sheep pre ...

The quality of Tibetan sheep meat from pastures was synergistically regulated by the rumen microbiota and related genes at different phenological stages

Frontiers in Veterinary Science
Meat quality is a key indicator of meat performance in ruminants, and its mechanism and regulation are also key to ruminant research. Studies have shown that animal meat quality is related to the gut microbiota.

Different lysine-to-methionine ratios in a low-protein diet affect the microbiome and metabolome, influencing the jejunal barrier function in Tibetan sheep

Frontiers in Microbiology
Introduction The objective of this study was to evaluate the effects of the dietary lysine (Lys)/ methionine (Met) ratio in a low-protein diet on short-chain fatty acid (SCFA) profiles, villus morphology, antioxidant capacity, and immune status of the ...

Dietary Overlap of Przewalski's Gazelle, Tibetan Gazelle, and Tibetan Sheep on the Qinghai‐Tibet Plateau

The Journal of Wildlife Management, 2008
Abstract: We studied food composition and overlap among sympatric Przewalski's gazelle ( Procapra przewalskii ), Tibetan gazelle ( P.

Tibetan Wild Sheep Scandal

2012
High rolling hills flank us as we drive up a remote valley in central Qinghai, heading generally eastward as part of our 2006 Tibetan Plateau traverse, described in Chapter 7. It is December 5 and here at over 15,500 feet it is bitter cold. On a ridge crest, we spot a Tibetan argali sheep, a large ram standing proudly erect, head raised and displaying ...

Blood mineral status of grazing Tibetan sheep in the Northeast of the Qinghai–Tibetan Plateau

Livestock Science, 2011
Abstract We investigated the macro-mineral status in free-grazing Tibetan sheep (Ovis aries) and their forage diets. The study was conducted in 4 counties in the northeast of the Qinghai–Tibetan Plateau. Forage samples and blood serum from 20 sheep in each county were collected in July (summer) and December (winter), and analyzed to determine the ...

Seroprevalence of Toxoplasma gondii Infection in Tibetan Sheep in Tibet, China

Journal of Parasitology, 2011
In the present investigation, the seroprevalence of Toxoplasma gondii antibodies in 455 Tibetan sheep in Tibet, China, was examined using an indirect hemagglutination test. Of these, 26 (5.7%) Tibetan sheep were seropositive at the cut-off of 1:64 serum dilution.
