Core Tip

Core Tip: In this study, we identified the downregulation of serum amyloid A1 (SAA1) in hepatocellular carcinoma (HCC). SAA1 expression could predict the favorable prognosis for HCC patients, especially for those patients without hepatitis virus infection. SAA1 expression was closely associated with anti-tumor immune signaling pathways. We also identified two signature genes associated with SAA1, suggesting a favorable prognosis function of SAA1 for HCC patients.
