MetabolomicsRumen unprotected glucose tends to promote intramuscular fat deposition via microbial volatile fatty acid-mediated metabolic reprogramming in cattle: A multi-omics perspective through the rumen-jejunum axis

Background: The regulatory effects of glucose absorption at different sites (rumen vs. small intestine) on lipid metabolism exhibit significant variation in beef nutrition. This study aimed to investigate the regulatory pathways of rumen-protected or unprotected glucose on lipid metabolism throug...

TranscriptomicsGene expression profiling in a Duroc/Landrace pig population differing in intramuscular fat content
The experiment aimed at studying gene expression differences in longissimus dorsi muscle from pigs from two groups: High versus low intramuscular fat (IMF). The animals were selected from a crossbred population of Landrace x Yorkshire/Landrace x Duroc animals, where we have previously found a highly...

ProteomicsIntegrative analysis of transcriptomics and proteomics of Longissimus dorsi muscle to identify proteins underlying intramuscular fat content in pigs
The Laiwu pig is famous for its excessively higher level of IMF content, however, the exact regulatory mechanism is still unknown. The intramuscular fat content (IMF) is an economically important traits in pigs, which is controlled by multiple genes and biological pathways. In the present study, we ...

ProteomicsIdentification of candidate genes that specifically regulate subcutaneous and intramuscular fat deposition from transcriptomic and proteomic profiles in Dingyuan pigs
we collected tissues of subcutaneous fat and longissimus dorsi (LD) muscle from individuals that have divergent of backfat thickness and intramuscular fat content, and have similar age and body weight. The transcriptomic and proteomic data were gained using RNA-Seq and TMT to identify the key genes ...

TranscriptomicsPorcine intramuscular fat content and composition are regulated by quantitative trait loci with muscle-specific effects
Intramuscular fat (IMF) storage is a biological process with strong impact on nutritional and technological properties of meat, and also with relevant consequences on human health. The genetic architecture of IMF content and composition phenotypes has been thoroughly studied in pigs through the iden...

ProteomicsLivers of chickens with high/low intramuscular fat or high/low abdominal fat deposition
This project investigated hepatic proteomic profiles associated with tissue-specific fat deposition in chickens. Chickens were grouped according to the intramuscular fat content of the breast muscle and abdominal fat content. Liver samples from chickens with high or low intramuscular fat deposition ...

TranscriptomicsIntramuscular fat variability in pigs
Intramuscular (i.m.) fat content influencing consumer’s acceptability of pork is considered as a limiting factor for meat quality. To gain insight into the biological basis of individual variability in i.m. fat content, both gene expression profiling and proteomic investigation were associated in ...

TranscriptomicsTranscriptome Profiling of Longissimus Dorsi Muscle of Donkeys with High and Low Intramuscular Fat Content
The content of intramuscular fat (IMF) is closely related to meat quality traits. In this study, in order to explore the candidate genes related to IMF content, the longissimus dorsi muscle of Guangling donkey was measured for intramuscular fat content. According to its intramuscular fat content, it...
