Summary: The objective of this study was to evaluate the performance of Chino Santandereano creole cows in the ultrasound-guided follicular aspiration technique (OPU) and the quality of oocytes recovered. Fifteen multiparous cows from a tropical climate region were selected and underwent 5 sessions of follicular aspiration with a 45-day interval. On average, 7.9+/-0.7 oocytes were recovered per cow, with a recovery rate of 64.9%+/-0.5, and a viable and non-viable oocyte rate of 64.3%+/-0.6 and 35.7%+/-0.7, respectively. A significant difference (P < 0.05) was observed in oocyte quality among grades I, II, and III (7.7+/-0.4, 19.8+/-0.5, and 36.8+/-0.5, respectively). These findings suggest that Chino Santandereano cows show a higher recovery rate of grade III oocytes in the OPU technique.

Summary: This study analyzed the differences in DNA methylation between zebu and taurine cattle and identified pathways and candidate genes associated with disease, disease resistance, and economic traits. These findings provide a foundation for further screening of characteristic epigenetic molecular markers in zebu and support genetic improvement of domestic cattle.

Summary: This study compared the alignment of sequence data from different breeds of cattle to two different reference genomes, revealing that aligning to UOA_Brahman_1 detected more SNVs, especially in cross-subspecies alignments. Unexpectedly low SNV counts in certain regions suggest the presence of taurine DNA in the UOA_Brahman_1 reference genome. Analysis of taurine-introgressed loci using principal component and admixture analyses confirmed the presence of these loci.

Summary: The study aimed to improve superovulation response and in-vivo embryo production in Holstein Frisian (HF) and Crossbred (XB) cows by using controlled internal drug release (CIDR)-GnRH or CIDREB along with conventional superovulation protocol. Results showed that CIDR-GnRH and CIDR-EB groups had significantly higher super-estrus follicles, multiple corpora lutea, ovulation/fertilization percentage, fertilized structures recovered, and transferable embryos, with shorter days for return to estrus after embryo collection compared to the control group. XB donor cows performed better than HF donor cows under subtropical conditions.

Summary: This study called and compared autosome-wide CNVs in Eurasian taurine, Asian indicine, African taurine, and African humped cattle using NGS data, revealing significant population differentiated CNVRs and genes that may be under selection, including those related to various traits. Additionally, breed- and individual-level comparisons of CNVR presence or copy number showed important CNVs potentially influencing cattle adaptation to different environments, based on the largest dataset of 336 individuals and 39 breeds analyzed with short Illumina reads.

Summary: Using a whole-genome assembly of Bos taurus, the author applied a bioinformatics strategy to identify candidate imprinting control regions (ICRs) throughout the genome. The study focused on the role of genomic imprinting in mammalian embryogenesis. By analyzing peaks in plots and examining genes near candidate ICRs, potential imprinted genes were identified. The ENCODE data from mouse studies provided valuable insights into the regulatory mechanisms for cattle.

Summary: Brazil is the largest exporter of beef in the world, with most of its beef derived from Nellore cattle. The history of Nellore cattle in Brazil involves importation of bulls from India, leading to genetic influences from both zebu and taurine breeds. Despite the small average taurine ancestry of approximately 1%, some taurine variants significantly impact traits such as body size and horn characteristics in Nellore cattle.

Summary: The research identified the important role of m(6)A methylation in transcriptional regulation and RNA metabolism during bovine skeletal myogenesis. Analysis on differentially methylated genes revealed that m(6)A modification may affect myoblast differentiation by mediating the expression of specific genes.

Summary: Recent research showed that Bos indicus-influenced cows had greater resilience to nutrient restriction and establishing pregnancy compared to B. taurus cows. Differences in metabolic profiles between these two types of cows were explored, with the study finding that the negative impacts of nutrient restriction on the somatotropic axis were heightened in B. taurus females compared to B. indicus-influenced cohorts.

Summary: Every week, 1-2 breeds of farm animals, including local cattle, disappear in the world. As the keepers of rare allelic variants, native breeds potentially expand the range of genetic solutions to possible problems of the future, which means that the study of the genetic structure of these breeds is an urgent task. Providing nomadic herders with valuable resources necessary for life, domestic yaks have also become an important object of study.

Summary: This study used geometric morphometry techniques to measure the degree of asymmetry in the autopods of healthy Brown Pyrenean calves. The results showed that the right hind limbs tend to rotate outwards, while the left hind limbs tend to rotate inwards. These findings are important for evaluating the function of each hind limb during standing and locomotion in cattle.

Summary: This study demonstrates the combined effects of positive selection and adaptive introgression on the modern bovine genome through in-depth assessment of sequence variation on a whole-genome scale. The observed hotspots of runs of homozygosity (ROH) haplotypes were confirmed to be results of positive selection and were associated with productive traits in modern Bos taurus cattle breeds. The study also identifies the introgression events of haplotypes from Bos indicus to Bos taurus, contributing to the formation of the current bovine genome.

Summary: Research has found that in living cells, monomeric RECQL helicase is more abundant than oligomer forms, and the monomeric form displays higher helicase and ATPase activities. This discovery has important implications for understanding endogenous RECQL oligomeric structures and their regulation, and also warrants a reexamination of the oligomeric states of other members of the RecQ family helicases in living cells.

Summary: Through transcriptome analysis of gayal, yak, and cattle, it was found that there are differences in gene expression among them in the plateau environment. Gayal and yak have highly similar adaptability to high-altitude environments, involving multiple physiological functions. Additionally, gayal and yak have many unique expression regulatory genes in adapting to high-altitude environments. These findings provide valuable insights into the complex transcriptome expression pattern and regulatory mechanisms of high-altitude domestication in gayal and yak.

Summary: The study found that healthy aging in old men is associated with upregulation of apoptosis and immune function, as well as downregulation of glycolysis and protein catabolism, while metabolic syndrome is mainly characterized by upregulation of proteolysis and downregulation of oxidative phosphorylation. This indicates potential muscle biomarkers for healthy aging and metabolic syndrome in old men.

Summary: The study aimed to evaluate whether the saliva protein composition of elderly individuals can reflect their dietary habits and investigated the impact of type 2 diabetes on the saliva-diet correlation. Results showed that the saliva proteome composition was associated with the intake level of certain food groups, especially vegetables, fruits, sweet snacks, and red meat. The study also identified some biological processes consistently affected by diet.
