Summary: Follistatin (FST) is an important regulator of skeletal muscle growth and adipose deposition through its ability to bind to members of the TGF-beta superfamily. This study generated transgenic pigs that express human FST specifically in skeletal muscle tissues and found that these pigs exhibited increased muscle growth, decreased adipose deposition, and improved metabolism. Transcriptome analysis revealed the involvement of various signaling pathways and metabolic processes in the phenotypic changes observed. These findings provide new insights into the molecular mechanisms underlying the effects of FST in pigs.

Summary: The experiment showed that supplementing piglets with blood plasma and yeast significantly improved growth performance, nutrient digestibility, fecal microbial, and reduced harmful gas emissions. This suggests that the dietary supplement with blood plasma and yeast could serve as an excellent alternative to antibiotics growth promoters in the diet of weaned piglets.

Summary: This study evaluated the impact of supplementing glutamic acid to reduced protein diets on the growth performance of weanling pigs. The results showed that supplementing glutamic acid enhanced the body weight, average daily gain, and gain-to-feed ratio of the weanling pigs. The study also observed a linear increase in these growth parameters with increasing levels of glutamic acid. Additionally, the supplementation of glutamic acid had an effect on ammonia and methyl mercaptans emissions.

Summary: The inhibition of MSTN1 in transgenic red carp promoted muscle growth without affecting muscle fat content, which differs from mammals. The study found that the expression of MSTN1 propeptide and growth-related genes were significantly higher in transgenic red carp, indicating muscle hypertrophy.

Summary: The study provides empirical evidence on the environmental impact of inequality and suggests that reducing inequality levels can increase carbon footprints. There is a conflict of objectives in relatively rich and egalitarian countries for surface sealing and forest land use, while relatively poor and initially unequal countries have room for jointly reducing environmental impacts and inequality. The results highlight the importance of accompanying policy measures to reduce inequality with policies that limit harmful environmental impacts in order to achieve joint reductions in inequality and environmental impact, especially in wealthier countries.

Summary: Research on genetically modified animals has mostly focused on mice, but also includes species like pigs that are more physiologically similar to humans, and cross-species comparisons with phylogenetically distant species like chickens. CRISPR-Cas9 is a versatile genetic editing method applicable across various species. The successful generation of transgenic chickens and pigs that express Cas9 in all organs has confirmed the functionality of Cas9 across different target genes, cell types, and in vivo applications.

Summary: This study examined the effects of feeding frequency on growth performance, nutrient digestibility, carcass quality, and lipid metabolism in growing-finishing pigs. The results showed that reducing feeding frequency improved feed conversion ratio and had an impact on fat deposition and carcass composition. This study provides a new approach to feeding and management of growing-finishing pigs.

Summary: Leptin overexpressing transgenic pigs exhibited elevated levels of leptin protein and mRNA expression, leading to impaired growth, decreased subcutaneous fat, altered lipid metabolism, and dysregulation of lipid metabolism related genes at different fat depots and adipocytes levels. These findings suggest that leptin overexpression can disrupt the balance between lipolysis and lipogenesis, resulting in decreased subcutaneous fat depots and potential modeling for obesity and related metabolic disorders.

Summary: This study evaluates the performance of alternative sandwich materials with reduced environmental impact under loading conditions relevant to boat design. Compared to traditional PVC foam sandwich materials, flax and bamboo composite faced PET foam sandwich materials have lower flexural stiffness and damage initiation levels, but they show promising support for impact energy levels that could be further improved with facing enhancements.

Summary: This study introduces Ge into the Ni-P system to synthesize Ni-Ge-P composites as anodes for lithium-ion batteries. The results show that the Ge-substituted Ni-Ge-P composites exhibit improved electrochemical reversibility and reduced redox potential compared to Ni-P anodes. The Li-storage mechanism of a selected NiGe0.5P0.5/Ni2Ge0.5P0.5 composite was investigated and a topological conversion reaction mechanism was proposed.

Summary: This study presents a strategy to enhance HDR efficiency in animal cells by spatial and temporal colocalization of the donor and Cas9 through coupling the CRISPR system with the transcription factor THAP11. By appending THAP11-specific DNA binding motifs to the double-stranded donor DNA, the HDR efficiency can be significantly improved. The THAP11-fused CRISPR system achieved a more than twofold increase in HDR-mediated knock-in efficiency, and up to 6-fold increase can be achieved through combinational use with the small-molecule HDR enhancer valnemulin.

Summary: This review discusses the function and mechanism of micro RNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) in regulating spontaneous abortion (SA). It suggests the existence of a competitive endogenous RNA (ceRNA) regulatory network in the onset and development of SA. Understanding this network is important for the search of potential RNA markers for SA diagnosis and treatment.

Summary: This study generated mutant mice with resistance to pseudorabies virus (PRV) by introducing a single amino acid substitution. The mutant mice showed alleviated disease manifestations, decreased death rate, and reduced viral loading in serum and tissue compared to wild-type mice. However, the mutation also caused a defect in eye development.

Summary: Farm animals' salivary glands have the potential to efficiently produce human therapeutic proteins. This study successfully used transgenic pigs to synthesize and purify biologically active human nerve growth factor (hNGF) from their salivary glands. The method employed the replacement of the endogenous gene to avoid contamination during purification. This research is significant for human health and biomedicine.

Summary: In this study, we identified four missense mutations that could affect MC1R protein function for eumelanin synthesis by comparing MC1R gene sequences. Using CRISPR-mediated homologous recombination, we successfully mutated the e allele in Duroc pigs to the dominant E-D1 allele at the MC1R locus, leading to uniform black coat color. The modified pigs carried a heterozygous E-D1/e allele at the MC1R locus and retained the genetic background of Duroc breed. Our work provides a gene editing method for pig coat color manipulation.

Summary: The study found that miR-21-5p can be absorbed by sperm through seminal plasma-derived EVs, overexpression of miR-21-5p inhibits sperm capacitation and acrosome reaction, and the expression level of VCL protein is lower in capacitated sperm. These results suggest that miR-21-5p can prevent sperm capacitation through VCL inhibition.
