Effect of paternal resveratrol intake on mitochondria and telomere length in mouse embryos and offspring [0.03%]
Noko Teramoto,Nanako Kobayashi,Kokoa Mitsui et al.
Noko Teramoto et al.
Advanced paternal age affects embryonic development and offspring phenotypes. We previously demonstrated that resveratrol prevents age-associated declines in the mitochondrial DNA copy number (mt-cn) and telomere length (TL) in embryos. The...
Sex determination and genetic screening of equine embryos with whole genome amplification and real-time PCR [0.03%]
全基因组扩增和实时PCR技术在马胚胎性别鉴定及基因筛查中的应用研究

In vitro experiments have become a powerful alternative to in vivo approaches for analyzing gene functions and molecular mechanisms. However, successful in vitro oogenesis using the C57BL/6 strain-widely used as a standard mouse model in ma...
Interactions among progesterone, estradiol, and γ-aminobutyric acid in rat spermatozoal hyperactivation [0.03%]
孕酮、雌二醇和γ-氨基丁酸在大鼠精子活化的相互作用关系研究
Miki Muroi,Shiho Fukuda,Miki Takahashi et al.
Miki Muroi et al.
Our previous study in hamsters indicated that progesterone (P) induces enhancement of spermatozoal hyperactivation, while 17β-estradiol (Eβ) and γ-aminobutyric acid (GABA) suppress this enhancement. Since P has also been shown to enhance...
N-myristoyltransferase 1, a key gene for protein N-myristoylation, is dispensable for fertility in male mice [0.03%]
蛋白N- myristoylation关键基因N-myristoyltransferase 1对雄性小鼠生育能力是不可缺少的
Yang Liu,Yvxia Zhang,Hailing Ding et al.
Yang Liu et al.
N-Myristoyltransferase 1 (NMT1), the predominant enzyme catalyzing myristoylation of proteins, is involved in various biological processes, including early embryonic development, immune responses, apoptosis, cellular homeostasis, tumorigene...
Effects of thiol compounds on DNA-damage detection and in vitro fertilization outcomes in bovine sperm [0.03%]
硫醇化合物对公牛精子DNA损伤检测及体外受精结局的影响
Kumiko Takeda,Kazuko Ogata,Kazutsugu Matsukawa et al.
Kumiko Takeda et al.
Reduced glutathione (GSH), a thiol compound, plays an important role in protecting sperm from excessive levels of reactive oxygen species. Our previous study demonstrated that GSH supplementation was associated with improved in vitro fertil...
