Abstract
Polyunsaturated fatty acids (PUFAs) such as linoleic acid (18:2, n-6) and α-linolenic acid (18:3, n-3) are essential for the growth, development, and well-being of mammals. However, most mammals, including humans, cannot synthesize n-3 and n-6 PUFAs and these must be obtained through diet. The beneficial effect of converting n-6 polyunsaturated fatty acids (n-6 PUFAs) into n-3 polyunsaturated fatty acids (n-3 PUFAs) has led to extensive research on the flax fatty acid desaturase 3 (Fad3) gene, which encodes fatty acid desaturase. Still, the plant-derived Fad3 gene is used much less in transgenic animals than the Fat-1 gene from Caenorhabditis elegans. To address this problem, we used somatic cell nuclear transfer (SCNT) technology to create codon-optimized Fad3 transgenic cattle. Gas chromatographic analysis showed that the n-3 PUFA content of transgenic cattle increased significantly, and the ratio of n-6 PUFAs to n-3 PUFAs decreased from 3.484 ± 0.46 to about 2.78 ± 0.14 (p < 0.05). In conclusion, Fad3 gene knock-in cattle are expected to improve the nutritional value of beef and can be used as an animal model to study the therapeutic effects of n-3 PUFAs in various diseases.

Huang J, Wang S, Feng X, Liu X, Zhao J, Zheng Q, Wei X, Ma Y. miRNA transcriptome comparison between muscle and adipose tissues indicates potential miRNAs associated with intramuscular fat in Chinese swamp buffalo.

Abstract
The amount of intramuscular fat (IMF) affects the tenderness and juiciness of beef and is an important indicator of beef quality. A few miRNAs involved in IMF deposition have been identified in other livestock. However, in the buffalo, the association between miRNA and IMF has not been reported and the miRNA expression profile remains poorly understood. In this study, small RNA sequencing was performed to characterize the miRNA expression pattern in muscle and adipose tissues using the Illumina platform. A total of 108 differentially expressed (DE) miRNAs were identified, including 98 known miRNAs and 10 novel miRNAs. A qRT-PCR experiment confirmed the quality of the DE analysis. Eight DE miRNAs showed high expression in adipose tissue and a considerable expression level in muscle tissue. Functional enrichment indicated that bta-miR-148a, bta-miR-143, bta-miR-10b, bta-let-7i, bta-let-7f, bta-let-7b, bta-miR-30a-5p, and bta-miR-100 were significantly associated with adipogenesis, suggesting these as candidate regulators for IMF deposition in buffalo. However, further functional validation is required. This is the first characterization of the miRNA expression profile in the muscle and adipose tissues of buffalo. These results provide information for the identification of miRNAs with potential effects on IMF deposition in buffalo.
