Myostatin is a transforming growth factor-β family member that acts as a negative regulator of skeletal muscle mass. To identify possible myostatin inhibitors that may promote muscle growth, we used RNA interference mediated by a lentiviral vector to knockdown myostatin in goat fetal fibroblast cells. We also investigated the expression changes in relevant(More)
BACKGROUND Canine hip dysplasia (HD) is a common polygenic trait characterized by hip malformation that results in osteoarthritis (OA). The condition in dogs is very similar to developmental dysplasia of the human hip which also leads to OA. METHODOLOGY/PRINCIPAL FINDINGS A total of 721 dogs, including both an association and linkage population, were(More)
BACKGROUND Growth and meat production traits are significant economic traits in sheep. The aim of the study is to identify candidate genes affecting growth and meat production traits at genome level with high throughput single nucleotide polymorphisms (SNP) genotyping technologies. METHODOLOGY AND RESULTS Using Illumina OvineSNP50 BeadChip, we performed a(More)
In recent years, genome-wide association studies have successfully uncovered single-nucleotide polymorphisms (SNPs) associated with complex traits such as diseases and quantitative phenotypes. These variations account for a small proportion of heritability. With the development of high throughput techniques, abundant submicroscopic structural variations(More)
BACKGROUND Whether myofibers increase with a pulsed-wave mode at particular developmental stages or whether they augment evenly across developmental stages in large mammals is unclear. Additionally, the molecular mechanisms of myostatin in myofiber hyperplasia at the fetal stage in sheep remain unknown. Using the first specialized transcriptome-wide sheep(More)
In this study, a single-trait genomic model (STGM) is compared with a multiple-trait genomic model (MTGM) for genomic prediction using conventional estimated breeding values (EBVs) calculated using a conventional single-trait and multiple-trait linear mixed models as the response variables. Three scenarios with and without missing data were simulated; no(More)
The discovery and identification of Ovis aries (sheep) miRNAs will further promote the study of miRNA functions and gene regulatory mechanisms. To explore the microRNAome (miRNAome) of sheep in depth, samples were collected that included eight developmental stages: the longissimus dorsi muscles of Texel fetuses at 70, 85, 100, 120, and 135 days, and the(More)
Embryonic germ cells (EG) are undifferentiated stem cells isolated from cultured primordial germ cells (PGC). Like embryonic stem cells (ES), EG are also capable of proliferation and self-renewal and have the capacity to differentiate in vitro into all cell types. To date, it has been proven that ES are capable of directed differentiation into neural(More)
Sub-populations of Chinese Mongolian sheep exhibit significant variance in body mass. In the present study, we sequenced the whole genome DNA methylation in these breeds to detect whether DNA methylation plays a role in determining the body mass of sheep by Methylated DNA immunoprecipitation - sequencing method. A high quality methylation map of Chinese(More)
BACKGROUND Muscle development and lipid metabolism play important roles during fetal development stages. The commercial Texel sheep are more muscular than the indigenous Ujumqin sheep. RESULTS We performed serial transcriptomics assays and systems biology analyses to investigate the dynamics of gene expression changes associated with fetal longissimus(More)
