Summary: This study verified the polymorphisms of porcine IL-1A and IL-6 genes and found their associations with intramuscular fat content and fatty acid composition in commercial crossbred pigs. The results indicated that these genes play an important role in lipid content and fatty acid composition in pig muscles, confirming their significance as candidate genes for fatty acid composition.

Summary: The study analyzed RNA sequence data for subcutaneous fat (SCF), intramuscular fat (IMF), and longissimus dorsi muscle (LDM) samples from 155 F-6 pigs to investigate gene expression levels and network connectivity. Results showed significant differences in gene expression and network connectivity between SCF and IMF, with tissue-specific genes and network modules associated with fat deposition.

Summary: This study presents a method for estimating the quality of pork using computer vision technology and meat quality traits. The results showed correlations between IMF%, IIMF%, marbling score, backfat thickness, percentage of moisture, and pH value. The developed models achieved high accuracy and can be used for quick estimation of pork quality.

Summary: Intramuscular fat (IMF) is an important indicator of pork sensory quality, influenced by dietary nutrients, genes, and metabolic pathways in pigs. Nutrigenetics and nutrigenomics provide a powerful tool for estimating nutrient requirements and programming dietary nutrient supply based on individual pig's genetic make-up. Understanding the mechanisms of fat metabolism and IMF deposition is crucial for improving swine production and economically important traits.

Summary: Chinese indigenous pig breeds have higher intramuscular fat content and better meat quality. This study investigated the differential metabolites and lipids in the skeletal muscle of Laiwu and Yorkshire pigs, revealing their association with intramuscular fat content and meat flavor. The results showed that the Laiwu pig had a faster lipid droplet formation and contained more triglyceride, reflecting its higher intramuscular fat content.

Summary: This study investigates the functional effects of the rs8192678 polymorphism in the PPARGC1A gene on human white adipocyte biology. The results show that the rs8192678 mutation is associated with adipocyte differentiation and mitochondrial function, with decreased levels of PPARGC1A mRNA and PGC-1a protein. This dysregulation affects cellular differentiation and mitochondrial function.

Summary: This study found that the composition and abundance of colonic intestinal microflora in Tibetan pigs were closely related to their superior traits. Bifidobacteria, Ruminococcaceae, and Family-XIII-AD3011-Group are conducive to improving disease resistance in Tibetan pigs, while Lactobacillus and Solobacterium are the main bacterial communities involved in fat deposition in Tibetan pigs.

Summary: The study found significant differences in the activation of lipid metabolism-related biological processes, including lipogenesis, fatty acid transport, and fatty acid oxidation, between Large White and Min pigs in the PPAR and fatty acid metabolism signaling pathways. The activation of these pathways may play a positive role in reducing IMF content in pigs.

Summary: This study assessed the whole transcriptome expression profiles of pigs' Longissimus dorsi muscle with high and low IMF content to identify genes involved in porcine IMF adipogenesis. The findings revealed the involvement of non-coding RNAs in fatty acid metabolic processes, lipid metabolism, and fat cell differentiation. The study also constructed competing endogenous RNAs (ceRNA) regulatory networks, highlighting the roles of lncRNAs, circRNAs, and miRNAs in IMF deposition. These findings provide potential regulators and molecular regulatory networks for future research on IMF traits in pigs, which can aid in improving pork quality through marker-assisted selection.

Summary: The study aimed to evaluate the performance, carcass and pork quality traits, as well as the mRNA expression of genes related to intramuscular fat deposition in female pigs from different genetic lines. Despite similar performance, Duroc pigs had higher intramuscular fat content compared to hybrid pigs, which was associated with increased mRNA expression of key transcriptional factors and genes related to adipogenesis and lipogenesis.
