CHARACTERIZATION OF Ca2+ INFLUX PATHWAY(S) DURING MOUSE OOCYTE MATURATION
Calcium influx oocyte maturation SOCE Stim1 Phosphorylation
2014/12/10
Ca2+ signaling induced at fertilization, also known as oscillations, is essential in mammalian eggs to initiate early embryonic development. The generation of the oscillations relies on optimization o...
Effects of Ca2+ and HCO3- on Capacitation, Hyperactivation and Protein Tyrosine Phosphorylation in Guinea Pig Spermatozoa
Capacitation Hyperactivation Tyrosine Phosphorylation Sperm
2016/4/29
In our previous report, we demonstrated that the tyrosine phosphorylation of sperm proteins (TPSP) of guinea pig was associated with capacitation and hyperactivation (CAHA), and Ca2+ and HCO3- were re...
大黄素升高豚鼠结肠带细胞[Ca2＋]I的特征和GDP的抑制作用
大黄素(Emodin) 豚鼠结肠带细胞(Guinea pig taenia coli cells) [Ca2＋]I GDP 动力学(Kinetics)
2008/3/6
利用Fluo－3荧光探针检测细胞内自由Ca2＋浓度([Ca2＋]I),研究了大黄素升高豚鼠结肠带细胞[Ca2＋]I的量―效关系和动态变化特征,及GDP和胞外Ca2＋浓度对其的影响。较低浓度大黄素随药物浓度增加使[Ca2＋]I显著升高，更高浓度大黄素有超最大抑制效应。GDP对大黄素升高细胞[Ca2＋]I的抑制作用随其浓度增加而增强。GDP和胞外Ca2＋浓度影响大黄素诱发的[Ca2＋]I动态变化的...
