哺乳动物

A small, herbivorous, extinct mammal of the genus Hyracotherium from the Eocene Epoch of the western United States, having four-toed front feet and three-toed hind feet and related ancestrally to the horse.

The main research achievements on oogenesis and embryogenesis in mammals are described in this review,including the resumption of meiotic division;activation of MⅡ oocyte;development of parthenogenetic,gynogenetic,androgenetic and reconstituted embryos;and the genetic and reproductive potentials of chromosomes within the first and the second polar body.

本研究将论述哺乳动物卵子发生和胚胎发生的最新研究进展，包括：减数分列的启动， MⅡ期卵母细胞的激活，孤雌胚、雌核胚、雄核胚和重组胚的发育以及第一与第二极体染色体的遗传和生殖潜力。

That means Pho85 kinaseand calcineurin were involved in salt tolerance with an identical target protein or in 中科院上海生化与细胞所博士学位论文摘要 the same pathway. Inhibition of calcineurin decrease the YPH499, pho80? mutant,and pap1 (pcl7)? mutant Mn2+ tolerance but not that of pho85? mutant and thepho85? mutant was more sensitive to Mn2+ than YPH499, pho80? mutant, and pap1(pcl7)? mutant even with the addition of cyclosporin A. Therefore, the conclusioncould be drawn that PHO85 gene played a dominant role in Mn2+ homeostasisregulation in compare with calcineurin. As for Ca2+ tolerance, cyclosporin A canincrease the tolerance to Ca2+ of all the mutant mention above, that means Pho85kinase and calcineurin function antagonistically in regulation of Ca2+ homeostasis.In Bioinformatics, BRI3 gene is a novel gene without any function clue but givehigh conservation in mammalian.

我们通过钙调磷酸酶的特异抑制剂环孢菌素A研究了YPH499、+2+pho85缺失株、pho80缺失株、pap1缺失株在钙调磷酸酶失活后对Na、Mn、2+Ca金属离子敏感性的变化，结果显示Pho85蛋白激酶和钙调磷酸酶通过直接+或间接激活同一个靶蛋白或途径来增强细胞对Na的耐受；和钙调磷酸酶相比，2+PHO85的缺失对酵母细胞Mn耐受性的破坏是相对控制性的，钙调磷酸酶的失2+活不能进一步降低pho85缺失株对Mn的耐受能力；Pho85和钙调磷酸酶在对2+Ca的耐受调节中是相互拮抗的，钙调磷酸酶的失活能增加pho85缺失株和2+pho80缺失株的Ca耐受。i中科院上海生化与细胞所博士学位论文摘要对本实验室克隆的人新基因BRI3进行系统的生物信息学分析，发现它是一个在哺乳动物中保守的，但功能未知的基因。
