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)
Ovis aries is one of the most important agricultural livestock for meat production, and also is an ideal model organism for biological and comparative genomics studies. Many miRNAs have been reported for their important roles in developmental processes in various animals, but there is limited information about O. aries miRNAs. In this study, combining a(More)
Intramuscular fat (IMF) shortage causes the lack of juiciness and tenderness of goat meat, while peroxisome proliferator-activated receptor gamma 1 (PPARγ1) and gamma 2 (PPARγ2) play key roles in lipid metabolism. Nevertheless, their expression patterns and the relationship with IMF have been poorly exposed. Using quantitative polymerase chain reaction(More)
Live rabbits have previously been generated through nuclear transfer using adult cells as nuclear donors. We demonstrated in this study that transfected adult rabbit fibroblasts are also capable of supporting full-term development. The fibroblasts were transfected with a pEGFP-C1 plasmid using lipofectamine() 2000, and the transgenic cells were derived from(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 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 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)
Bacillus thuringiensis Cry8Ea toxin is specifically toxic to larvae of the Asian cockchafer, Holotrichia parallela. Here we investigated the mechanism of transcriptional regulation of the cry8Ea1 gene. Reverse transcription-PCR (RT-PCR) results indicated that cry8Ea1 and an upstream gene (orf1) were cotranscribed. Transcriptional fusions with the lacZ gene(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)
OBJECTIVE We studied the influence of spoIIID gene deletion on the activity of cry1Ac, cry3A, cry4A and cry8E gene promoters in Bacillus thuringiensis and compared the activity among these promoters in spoIIID mutant (HD-delta SpoIIID). METHODS We constructed 4 promoter fusions with lacZ gene and transformed them into wild-type strain HD-73 and(More)
