    • Embodiments herein relate to the field of screening tools for fetal/maternal wellness, and, more specifically, to biomarkers for gestational diabetes. In various embodiments, the methods may provide non-invasive and minimally-invasive screening tools for gestational diabetes that involve detection of changes in a proteomic profile of a test sample relative to a reference sample. In particular embodiments, the method may include determining whether a proteomic profile of a test sample from the subject includes at least one expression signature characteristic of gestational diabetes, wherein the proteomic profile comprises information on the expression of glycosylated fibronectin and glycosylated PSG, for example information on levels of fibronectin-SNA or a fibronectin-antibody complex, and PSG-AAL or a PSG-antibody complex. In some embodiments, the proteomic profile may also include information on the expression of adiponectin, sex hormone binding globulin (SHBG), C-reactive protein (CRP), a ratio of human chorionic gonadotropin (hCG) to placental lactogen, or a combination thereof.
    • 本文的实施方案涉及用于胎儿/母亲健康的筛选工具领域,更具体地,涉及用于妊娠糖尿病的生物标志物的领域。 在各种实施方案中,所述方法可以提供用于妊娠糖尿病的非侵入性和最小侵入性筛选工具,其涉及检测测试样品相对于参考样品的蛋白质组图谱的变化。 在具体实施方案中,该方法可以包括确定来自受试者的测试样品的蛋白质组图谱是否包括妊娠糖尿病特征的至少一个表达特征,其中蛋白质组学特征包括关于糖基化纤连蛋白和糖基化PSG的表达的信息,例如信息 纤连蛋白-SNA或纤连蛋白 - 抗体复合物水平,PSG-AAL或PSG-抗体复合物。 在一些实施方案中,蛋白质组学特征还可以包括关于脂联素,性激素结合球蛋白(SHBG),C-反应蛋白(CRP),人绒毛膜促性腺激素(hCG)与胎盘乳糖的比例或其组合的表达的信息 。
