Summary: A combined transcriptome and metabolome analysis revealed that Qinchuan cattle meat has a relatively high intramuscular fat content. CCDC80 and the HOX gene cluster may regulate the deposition of intramuscular adipose tissue. Erucic acid was identified as the main metabolite in Qinchuan beef cattle and its metabolism, regulated by ACOX3, HACD2, and SCD5 genes, affects the accumulation of intramuscular fat.

Summary: This study identified key genes involved in intramuscular fat formation in Japanese Black cattle, including COL4A5, highly expressed in intramuscular fat tissue. Pathway analysis revealed that differentially expressed genes in intramuscular fat tissue are related to cell adhesion, proliferation, and cancer pathways. Additionally, upregulation of TGF-beta and small GTPases regulators in intramuscular fat suggests their involvement in fat formation.

Summary: This study aimed to evaluate the effects of body condition score change, back fat depth change, and muscle diameter change on luteal activity and first estrus in Holstein cows. The findings suggest that extensive muscle loss postpartum is associated with a delayed start to luteal activity and first estrus, while marginal muscle loss and a gain in body condition are associated with an earlier start to luteal activity and first estrus.

Summary: Genetic lines have significant effects on carcass traits and pork quality. Terminal lines have lower backfat thickness, higher hardness and cohesiveness, and lower IMF content. Different muscles have different texture profiles, and collagen and IMF content greatly contribute to pork texture.

Summary: This study examined the feasibility of using hyperspectral imaging to predict the intramuscular fat (IMF) content in pork Longissimus thoracis et lumborum (LTL). The results showed that by using spectral data from Gluteus medius, the IMF content in the LTL could be accurately predicted, which could be useful in segregating pork LTL based on IMF content.

Summary: This study evaluated the ability of dual-energy X-ray absorptiometry (DEXA) to predict intramuscular fat (IMF) content of beef longissimus steaks compared to chemical IMF as the gold standard. DEXA accurately predicted fat content across a wide range, but had lower precision and accuracy for samples with low-fat content compared to high-fat content.

Summary: This study analyzed the transcriptome of purebred Anqing Six-end-white pigs with varying IMF content and identified differentially expressed genes, Gene Ontology terms, and pathways related to lipid metabolism. Gene set enrichment analysis revealed increased expression of genes related to ribosome function in the low IMF group. Protein-protein interaction network analyses identified promising candidate genes associated with IMF content.

Summary: This study investigates the role of N6-methyladenosine (m6A) modification in the regulation of intramuscular fat (IMF) deposition in poultry. The findings reveal a significant difference in IMF content between the breast and leg, with the leg having higher IMF content. The study identifies differentially methylated genes (DMGs) and pathways associated with IMF deposition, providing important insights for improving meat quality in indigenous chicken breeds.

Summary: This study analyzed lncRNAs in pig muscles with different meat quality and identified 500 differentially expressed lncRNAs and 2094 protein-coding genes. Through KEGG analysis, fat deposition was found to be the main reason for the differential phenotype, with cGMP-PKG and VEGF signaling pathways being the most important. Key genes and transcription factors related to differential fat deposition were characterized, providing candidate genes crucial for meat quality and contributing to molecular-breeding strategies.

Summary: This study investigated the relationship between long-chain fatty acids and intramuscular fat, revealing that saturated and monounsaturated fatty acids increased while polyunsaturated fatty acids decreased with higher IMF content. Furthermore, it was found that rates of endogenous synthesis for specific fatty acids increased with higher levels of IMF deposition.
