Complete Mitochondrial Genome Sequences of Chinese Indigenous Sheep with Different Tail Types and an Analysis of Phylogenetic Evolution in Domestic Sheep
Mitochondrial DNA Mitogenome Sheep Phylogenetic Mitochondrial Control Region
2016/5/20
China has a long history of sheep (Ovis aries [O. aries]) breeding and an abundance of sheep genetic resources. Knowledge of the complete O. aries mitogenome should facilitate the study of the evoluti...
Targeted Editing of Myostatin Gene in Sheep by Transcription Activator-like Effector Nucleases
Myostatin Targeted Gene Editing Sheep Primary Fibroblasts
2016/5/19
Myostatin (MSTN) is a secreted growth factor expressed in skeletal muscle and adipose tissue that negatively regulates skeletal muscle mass. Gene knockout of MSTN can result in increasing muscle mass ...

The objective of this study was to assess variance components and genetic parameters for fat and protein content in Tsigai sheep using multivariate animal models in which fat and protein content in in...
Inbreeding not to blame for Colorado’s bighorn sheep population decline,CU-Boulder study finds
Inbreeding not to blame Colorado’s bighorn sheep population decline CU-Boulder
2015/8/4
The health of Colorado’s bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has fo...
Presence of Transcription Factor OCT4 Limits Interferon-tau Expression during the Pre-attachment Period in Sheep
Interferon-tau Transcription Gene regulation Implantation Sheep
2016/5/11
Interferon-tau (IFNT) is thought to be the conceptus protein that signals maternal recognition of pregnancy in ruminants. We and others have observed that OCT4 expression persists in the trophectoderm...
