虽然阻塞性睡眠呼吸暂停(OSA)患者患心血管疾病(CVD)的风险很高,但目前只有一小部分被诊断出来。为了探索和鉴定OSA合并CVD患者差异表达的蛋白质/肽,进行基于质谱的唾液分析。在我们的研究中,在非CVD组和CVD组的唾液中观察到11个差异表达的峰。5个质量峰(1594.1、1673.7、1196.6、1290.5和1447.0 Da)在CVD组中显示上调趋势,而6个质量峰(3038.6、2164.3、2301.4、3195.0、2628.4和1721.9 Da)在CVD组中下调。  此外,与非CVD组相比,CVD组唾液中的α-2-HS-糖蛋白(AHSG)水平被证实降低。唾液肽组的分析提供了一种有前途的方法,以筛选新的生物标志物,然后进一步确定,并可能有助于早期诊断患有OSA的CVD患者。
Although obstructive sleep apnea (OSA) patients are at high risk of developing cardiovascular disease (CVD), only a small proportion is currently diagnosed. To explore and identify the differentially expressed proteins/peptides of OSA patients with CVDs, a mass spectrometry-based salivary analysis was performed. In our study, eleven peaks were observed differentially expressed in saliva from the non-CVD and CVD groups. Five masses mass peaks (1594.1, 1673.7, 1196.6, 1290.5, and 1447.0 Da) showed an upregulated trend in the CVD group, whereas six mass peaks (3038.6, 2164.3, 2301.4, 3195.0, 2628.4, and 1721.9 Da) were downregulated in the CVD group. In addition, the alpha-2-HS-glycoprotein (AHSG) levels in saliva were verified to be decreased in CVD group compared to non-CVD group. Analysis of the salivary peptidome provides a promising approach to screening for novel biomarkers before further identification, and may contribute to early diagnosis of CVD patients with OSA.
