Bovine Mammary Epithelial Cells mRNA Expression Milk Fat Milk Protein
2016/5/16
This study was conducted to determine the effects of saturated long-chain fatty acids (LCFA) on cell proliferation and triacylglycerol (TAG) content, as well as mRNA expression of αs1-casein (CSN1S1) ...
Association between Motilin Receptor Gene Haplotypes and Growth Traits in Japanese Hinai-dori Crossbred Chickens
Chicken Hinai-dori Growth Marker Gene Motilin Receptor
2016/5/16
We previously identified quantitative trait loci (QTL) for body weight and average daily gain in a common region between ADL0198 (chr 1: 171.7 Mb) and ABR0287 (chr 1: 173.4 Mb) on chicken chromosome 1...
Siberian Sturgeon Oocyte Extract Induces Epigenetic Modifications of Porcine Somatic Cells and Improves Developmental Competence of SCNT Embryos
Epigenetic Modifications Somatic Cell Nuclear Transfer Siberian Sturgeon Oocyte Extract
2016/5/16
Somatic cell nuclear transfer (SCNT) has generally demonstrated that a differentiated cell can convert into a undifferentiated or pluripotent state. In the SCNT experiment, nuclear reprogramming is in...

为重新分析韩国大麝鼩种群与相邻的俄罗斯远东种群之间的遗传分化情况,我们获得9 条来自韩国4 个地点和俄罗斯3 个地点的大麝鼩线粒体细胞色素b 基因(Cyt b)全序列,并将其与来自GenBank 的4 条Cyt b 全序列和4 条Cyt b 部分序列进行比较。结果发现韩国的大麝鼩并非只有一种基因型,因此,在利用Cyt b 部分序列进行种群遗传学分析时需格外注意。基于Cyt b 全序列分析,发现韩国...
利用韩国豹猫的IRBP、12S rRNA 和细胞色素b (Cyt b)序列,并将其与GenBank 中的豹猫及西表猫的上述基因进行比较,以此来重新分析韩国豹猫和其它豹猫及西表猫之间的遗传分化情况。首先,我们从18 只韩国豹猫的IRBP、12S rRNA 和Cyt b 序列分析中分别检测到6 个等位基因、1 个单倍型和3 个单倍型,推测曾经发生在豹猫种群的瓶颈事件可能是本文发现的不同分子标记之间存在...
