Proteomic analysis identifies GSN as non-invasive circulating serum biomarker for predicting early recurrence in hepatocellular carcinoma


ABSTRACT: Hepatocellular carcinoma (HCC) is susceptible to early recurrence and lacks effective predictive markers. Mass Spectrometry (MS)-based proteomics has emerged as a potent tool for identifying cancer biomarker profiles in various bodily fluids. In this study, we established a MS-based biomarker discovery and validation workflow. Firstly, the workflow successfully identified a total of 447 serum proteins in 179 individuals (126 HCC patients and 53 liver cirrhosis (LC)) using the Data Independent Acquisition-MS (DIA-MS) strategy. Then, candidate serum biomarkers were validated in 192 individuals (142 HCC patients and 50 LC patients) using Parallel Reaction Monitoring (PRM) strategy.

Hepatocellular carcinoma (HCC) is susceptible to early recurrence, but it lacks effective predictive biomarkers. In this study, we retrospectively selected 179 individuals as a discovery cohort (126 HCC patients and 53 liver cirrhosis (LC) patients) for screening candidate serum biomarkers of early recurrence based on data independent acquisition-mass spectrometry strategy. And then, the candidate biomarkers were validated in an additional independent cohort with 192 individuals (142 HCC patient  ...[more]
