需要更有效的生物标志物来促进肝细胞癌(HCC)的早期检测。我们的目的是通过蛋白质组学分析确定HCC检测的候选生物标志物。首先,我们对10对HCC和非肿瘤组织进行了全面的蛋白质组学分析。然后,我们在另一个组织队列中通过靶向蛋白质组学分析验证了排名靠前的蛋白质。最后,我们使用酶联免疫吸附试验在多个血清队列中验证候选生物标志物,包括HCC病例(HCC)、肝硬化病例(LC)和正常对照(NC)。我们鉴定并验证了33个在HCC组织中表达上调的蛋白。其中,8个分泌或膜蛋白在血清中进一步评估,揭示醛酮还原酶家族1成员B10(AKR 1B 10)和组织蛋白酶A(CTSA)可以区分HCC与LC和NC。AKR 1B 10和CTSA的曲线下面积(AUC)分别为0.891和0.894,大于甲胎蛋白(AFP; 0.831)。值得注意的是,组合三种蛋白质达到0.969的AUC,其优于单独的AFP(P< 0.05)。此外,手术后血清AKR 1B 10水平显著降低。AKR 1B 10和CTSA是HCC检测的潜在血清生物标志物。联合检测AKR 1B 10、CTSA和AFP可提高HCC的诊断效率。
More efficient biomarkers are needed to facilitate the early detection of hepatocellular carcinoma (HCC). We aimed to identify candidate biomarkers for HCC detection by proteomic analysis. First, we performed a global proteomic analysis of 10 paired HCC and non-tumor tissues. Then, we validated the top-ranked proteins by targeted proteomic analyses in another tissue cohort. At last, we used enzyme-linked immunosorbent assays to validate the candidate biomarkers in multiple serum cohorts including HCC cases (HCCs), cirrhosis cases (LCs), and normal controls (NCs). We identified and validated 33 up-regulated proteins in HCC tissues. Among them, eight secretory or membrane proteins were further evaluated in serum, revealing that aldo–keto reductase family 1 member B10 (AKR1B10) and cathepsin A (CTSA) can distinguish HCCs from LCs and NCs. The area under the curves (AUCs) were 0.891 and 0.894 for AKR1B10 and CTSA, respectively, greater than that of alpha-fetoprotein (AFP; 0.831). Notably, combining the three proteins reached an AUC of 0.969, which outperformed AFP alone (P< 0.05). Furthermore, the serum AKR1B10 levels dramatically decreased after surgery. AKR1B10 and CTSA are potential serum biomarkers for HCC detection. The combination of AKR1B10, CTSA, and AFP may improve the HCC diagnostic efficacy.
