文献和实验Nature 子刊:确定男性避孕关键基因,敲除后 98% 精子形态异常
的是,缺乏该基因也会引起严重的不育症,导致一种称为少精症的病症。这是人类男性不育症中最常见的情况,显示产生的精子数量减少、活动速度减慢和精子形状扭曲,因此精子无法与卵子融合。 在这项研究中,在雄性小鼠中敲除基因 Arrdc5 后,其产生的精子数量减少了 28%,移动速度比正常小鼠慢了 2.8 倍,大约 98% 的精子头部和中段异常。该结果表明,该基因编码的蛋白质是正常精子生产所必需的。 图片来源:Nature Communications 该研究团队表示,他们已经申请了一项临时专利,用于开发
Purification and Assay of Mammalian Group I and Group IIa Secretory Phospholipase A2
. They can be classified into at least four groups based on minor structural differences (1 ,2 ). In particular, two major classes of highly homologous secretory enzymes (class I and IIa) have been found in mammalian tissues. Mammalian class I PLA2 s are synthesized
RNA splicing. One form (IIA) includes and the other form (IIB) excludes a 69-amino acid cysteine-rich globular domain encoded by exon 2 in PIINP. During the process of synthesis, these N-propeptides are removed by specific proteases and released
