This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.
在彩鲫中,从未受精卵到胚胎发育的各个时期均可检测到表达,但表达量发生明显变化,受精后表达量迅速下降,直到原肠胚期表达量有所上升,并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同,可能与两种鱼不同的生殖方式有关。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.
结果显示:(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散,但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系,卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准,只有排出第一极体才能作为猪卵母细胞核成熟的标志;(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率,而且可加强卵丘细胞的扩散;(3)在现有实验条件下,在mTCM和mNCSU中添加10%pFF与在mNCSU中添加10%FCS相比可获得较高的猪卵母细胞核成熟率;(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样,但对体外受精后的早期胚胎发育影响不明显;(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。

Pig oocytes cultured in vitro for some time were inseminated by frozen–thawed ejaculated sperm. At specified times after insemination, sperm penetration, cell cycle progression and mitogen-activated protein kinase phosphorylation were evaluated. It was shown that:(1) oocytes at various maturational stages could be penetrated by sperm;(2) sperm penetration did not affect meiotic cell cycle progression;(3) sperm penetration of germinal vesicle oocytes and maturing oocytes did not alter MAPK phosphorylation; and (4) when premetaphase I and metaphase I oocytes, in which MAPK was activated, were fertilised, no evident MAPK dephosphorylation was detected as in metaphase II oocytes.
不同成熟阶段的猪卵与精子融合后体外培养发现:(1)不同成熟阶段的猪卵母细胞都可被精子穿透;(2)精子穿透不影响减数分裂细胞周期进程;(3)精子穿透GV期卵母细胞和正在成熟的卵母细胞不改变MAPK磷酸化:(4)已受精的前中期I和中期I卵母细胞的MAPK有活性,MAPK不像MII卵母细胞那样受精后发生磷酸化。

dispermy:双精受精
例如应用高浓度的精液或授精前用氯仿等麻醉剂、尼古丁等生物碱进行处理则可引起多精现象和卵裂异常. 这些实验性多精受精现象,常常作为研究单精受精机制的手段而被应用. 相应地精子只是两个的时候,则称为双精受精(dispermy),在最初卵裂中可出现三个极.
