BACKGROUND Human follicular fluid (FF) is a unique biological fluid in which the oocyte develops in vivo, and presents an optimal source for non-invasive biochemical predictors. Oocyte quality directly influences the embryo development and hence, may be used as a predictor of embryo quality. Peptide profiling of FF and its potential use as a biomarker for oocyte quality has never been reported. METHODS This study screened FF for peptide biomarkers that predict the outcome of in vitro fertilization (IVF). Potential biomarkers were discovered by investigating 2 training datasets, consisting both of 17 samples and validating on an independent experiment containing 32 samples. Peptide profiles were acquired by nano-scale liquid chromatography coupled to tandem mass spectrometry (nano LC-MS/MS). RESULTS From the training datasets 53 peptides were found as potential biomarker candidates, predicting the fertilization outcome of 24 out of the 32 validation samples blindly (81.3% sensitivity, 68.8% specificity, AUC = 0.86). Seven potential biomarker peptides were identified. They were derived from: insulin-like growth factor binding protein-5, alpha-2-antiplasmin, complement component 3, inter-alpha-trypsin inhibitor heavy chain H1, serum albumin, protein diaphanous homolog 1 and plastin-3. CONCLUSIONS The MS-based comprehensive peptidomic approach carried out in this study, established a novel panel of potential biomarkers that present a promising predictive accuracy rate in fertilization outcome, and indicates FF as an interesting biomarker resource to improve IVF clinic routine.

人体体外受精结果的卵泡液生物标志物:原理证明。

背景技术人卵泡液(FF)是卵母细胞在体内发育的独特生物流体,并为非侵入性生化预测因子提供了最佳来源。卵母细胞的质量直接影响胚胎的发育,因此可以用作胚胎质量的预测指标。FF的肽谱分析及其作为卵母细胞质量生物标志物的潜在用途尚未见报道。方法:本研究筛选了FF,以预测体外受精(IVF)结果的肽生物标志物。通过研究2个训练数据集(包括17个样本)并在包含32个样本的独立实验中进行验证,发现了潜在的生物标志物。通过与串联质谱联用的纳米级液相色谱(纳米LC-MS / MS)获得肽谱。结果从训练数据集中发现了53种肽作为潜在的生物标志物候选物,盲目预测了32个验证样品中的24个受精结果(敏感性为81.3%,特异性为68.8%,AUC = 0.86)。鉴定了七个潜在的生物标志物肽。它们来自:胰岛素样生长因子结合蛋白5,α-2-抗纤溶酶,补体成分3,α-胰蛋白酶间抑制剂重链H1,血清白蛋白,透色同源物1和plastin-3。结论在这项研究中进行的基于MS的综合肽组学方法建立了一组潜在的生物标志物,它们在受精结局中显示出有希望的预测准确率,并表明FF是改善IVF临床常规的有趣生物标志物资源。盲目地预测了32个验证样品中24个的受精结果(敏感性为81.3%,特异性为68.8%,AUC = 0.86)。鉴定了七个潜在的生物标志物肽。它们衍生自:胰岛素样生长因子结合蛋白5,α-2-抗纤溶酶,补体成分3,α-胰蛋白酶间抑制剂重链H1,血清白蛋白,透色同源物1和plastin-3。结论在这项研究中进行的基于MS的综合肽组学方法建立了一组潜在的生物标志物,它们在受精结局中显示出有希望的预测准确率,并表明FF是改善IVF临床常规的有趣生物标志物资源。盲目地预测了32个验证样品中24个的受精结果(敏感性为81.3%,特异性为68.8%,AUC = 0.86)。鉴定了七个潜在的生物标志物肽。它们来自:胰岛素样生长因子结合蛋白5,α-2-抗纤溶酶,补体成分3,α-胰蛋白酶间抑制剂重链H1,血清白蛋白,透色同源物1和plastin-3。结论在这项研究中进行的基于MS的综合肽组学方法建立了一组潜在的生物标记物,它们在受精结局中显示出有希望的预测准确率,并表明FF是改善IVF临床常规的有趣生物标记物资源。鉴定了七个潜在的生物标志物肽。它们来自:胰岛素样生长因子结合蛋白5,α-2-抗纤溶酶,补体成分3,α-胰蛋白酶间抑制剂重链H1,血清白蛋白,透色同源物1和plastin-3。结论在这项研究中进行的基于MS的综合肽组学方法建立了一组潜在的生物标志物,它们在受精结局中显示出有希望的预测准确率,并表明FF是改善IVF临床常规的有趣生物标志物资源。鉴定了七个潜在的生物标志物肽。它们来自:胰岛素样生长因子结合蛋白5,α-2-抗纤溶酶,补体成分3,α-胰蛋白酶间抑制剂重链H1,血清白蛋白,透色同源物1和plastin-3。结论在这项研究中进行的基于MS的综合肽组学方法建立了一组潜在的生物标志物,它们在受精结局中显示出有希望的预测准确率,并表明FF是改善IVF临床常规的有趣生物标志物资源。
