摘要: In clinical practices, the therapeutic outcomes and prognosis of hepatocellular carcinoma (HCC) patients with different tumor numbers after surgery are very different; however, underlying mechanisms tumorigenesis development HCC still not well understood. Here, we systematically compared overall proteome profiles between primary single multiple lesions using iTRAQ-based quantitative proteomics approach. We identified that 107 330 proteins were dysregulated in tissue (MC group) a lesion (SC group), their non-cancerous (MN SN groups) respectively. The MC group concentrated UBC signaling pathway NFκB pathway, but SC more ERK pathway. These information revealed there might be molecular lesions. Furthermore, HSD17B13 only down-regulated while HK2 up-regulated among these proteins. Therefore, protein potential biomarkers for
