非损伤检测胎儿肺上皮细胞微环境中Cl流的变化情况

肺上皮细胞中体液运输由上皮细胞膜两侧渗透压产生的Na+和Cl-流调节支配,而离子转运过程中所需的能量是由活性Na+/K+ATP酶所提供,Na+和Cl-的跨膜分布是由配体调节的离子通道和交换器所控制,所以如果Cl-的转运发生缺陷将导致与体液运输失调相关的疾病。囊性纤维病的发生就是由于Cl-转运的缺失而

抗凋亡基因(CED-9)提高植株对盐胁迫和氧化应激的耐受性凋亡(Apoptosis)是细胞程序性死亡的一种,在调节植物对环境的适应性中起到重要作用。近期有研究表明动物的抗凋亡基因(CED-9)在植物中表达,能够显著提高植物对各种生物和非生物胁迫的耐受性,但隐藏在该现象下的最基本的细胞机制尚未被考察。

海洋原生生物破囊壶菌的渗透调节和对Na+的需求

破囊壶菌是低等的真菌,生长在大量的Na+环境中。 Na+参与细胞渗透调节和细胞代谢。渗透调节通过从环境中吸收无机离子,或者改变细胞质中可溶性物质的浓度来完成。通过质膜的渗透调节在转运过程中非常重要。但是在海洋原生生物中如何通过质膜进行渗透调节还不清楚。澳大利亚的科学家Shabala等人用非损伤微测技
