ARTICLE HIGHLIGHTS
Research background

Existing studies have shown that chondroitin sulfate proteoglycan, including VCAN, is a key component in the tumor microenvironment and may play an important role in hepatocellular carcinoma (HCC).

Research motivation

The role of VCAN in HCC has not yet been elucidated, especially in hepatitis B virus (HBV)-related HCC.

Research objectives

This study aimed to investigate the expression and potential mechanism of action of VCAN in HCC.

Research methods

We tested VCAN expression in serum of patients with HBV-associated HCC and cirrhosis, and explore the underlying mechanism of VCAN in HCC by bioinformatics methods.

Research results

VCAN may be a possible biomarker for the prognosis of HCC. VCAN was associated with HBV e antigen in HBV infected patients. VCAN may play a role in HCC through the extracellular matrix signaling pathway and inflammatory immune response.

Research conclusions

High VCAN level could be a possible biomarker for the poor prognosis of HCC, and its immunomodulatory mechanism in HCC deserves attention.

Research perspectives

Future studies will be conducted to explore the immune mechanism of VCAN in HBV-associated HCC.
