ABSTRACT
<p><b>OBJECTIVE</b>To identify specific serum glycoprotein profiles that correspond to the carcinogenic process of primary liver cancer (PLC) by analyzing a population with high-incidence of PLC using lectin affinity microarray.</p><p><b>METHODS</b>Serum samples were collected from individuals classified as high risk for PLC (including patients with liver cirrhosis and hepatitis B) and development of PLC was recorded. Healthy individuals served as normal controls. The serum samples were subjected to glycoprotein profling by using lectin microarrays and the results were confirmed by lectin blot. Between-group differences were statistically analyzed.</p><p><b>RESULTS</b>PLC carcinogenesis was found to be correlated with enhanced affinity for AAL, ACL, ConA, LCA, MPL, NML, PHA-E, PHA-L, PSA, RCA-I, STL, VAL,WGA, and SNA (P less than 0.05). These data implied that changes in specific glycan structures, such as aFuc, GlcNAc, GalNAc, mannose, bisecting GlcNAc and terminal beta1-4 Gal, may be involved in PLC carcinogenesis . The PLC group showed significantly different results for all detected lectins, except SNA (P less than 0.05). However, among the PLC group, the SNA affinity was not significantly different for the hepatitis B group (P =0.443, P more than 0.05).</p><p><b>CONCLUSION</b>Glycans may be associated with the carcinogenic process of PLC and may be developed as diagnostic and prognostic biomarkers of PLC in the future.</p>
