部分养殖鱼类存在两性生长异形的表型,因此,构建相应单性别养殖群体对水产养殖产量的提升具有产业应用价值。迄今为止,采用激素活性物质诱导产生性反转亲本是水产养殖业构建单性别群体最普遍使用的方法。本研究针对雌鲤生长快于雄鲤的两性生长异形的特性,以cyp17a1 为靶点进行了CRISPR/Cas9介导的基因编辑操作,利用cyp17a1 敲除后形成的伪雄鲤,成功构建了全雌鲤群体。首先,我们发现无论遗传性别型为XX还是XY,其cyp17a1 缺失鲤个体性腺均发育为精巢,并能正常产精。其次,利用确定的雄性特异DNA分子标记,筛选到cyp17a1 -/- XX伪雄个体,其具有正常的精巢发育和精子发生。将其与野生型雌鲤杂交,在8 月龄时检测后代性别,发现100%为雌性。将全雌群体和对照组雌雄混合群体各500 尾进行同塘生长对比养殖,至8 月龄或12 月龄时随机抽样检测,发现cyp17a1杂合突变雌鲤体重比同塘性别混养对照组分别高6.60%或32.66%。因此,本研究首次成功地利用基因工程技术对单基因位点进行操作,创制了全雌群体,实现了对雌鲤生长快的两性生长异形特性的应用,提升了养殖产量。

Immunoglobulin G (IgG) is the most abundant plasma glycoprotein and a prominent humoral immune mediator. Glycan composition affects the affinity of IgG to ligands and consequent immune responses. The modification of IgG N-glycosylation is considered to be one of the various mechanisms by which sex hormones modulate the immune system. Although the menstrual cycle is the central sex hormone-related physiological process in most women of reproductive age, IgG N-glycosylation dynamics during the menstrual cycle have not yet been investigated. To fill this gap, we profiled the plasma IgG N-glycans of 70 healthy premenopausal women at 12 time points during their menstrual cycles (every 7 days for 3 months) using hydrophilic interaction ultra-performance liquid chromatography (HILIC-UPLC). We observed cyclic periodic changes in the N-glycosylation of IgG in association with the menstrual cycle phase and sex hormone concentration in plasma. On the integrated cohort level, the modeled average menstrual cycle effect on the abundance of IgG N-glycosylation traits was low for each trait, with the highest being 1.1% for agalactosylated N-glycans. However, intrapersonal changes were relatively high in some cases; for example, the largest difference between theminimum and maximum values during themenstrual cycle was up to 21% for sialylated N-glycans. Across all measurements, the menstrual cycle phase could explain up to 0.72% of the variation in the abundance of a single IgG glycosylation trait of monogalactosylation. In contrast, up to 99% of the variation in the abundance of digalactosylation could be attributed to interpersonal differences in IgG N-glycosylation. In conclusion, the average extent of changes in the IgG N-glycopattern that occur during the menstrual cycle is small; thus, the IgG N-glycoprofiling of women in large sample-size studies can be performed regardless of menstrual cycle phase.
