Glycoproteomics analysis of plasma proteins associated with Opisthorchis viverrini infection-induced cholangiocarcinoma in hamster model
Journal Title: Asian Pacific Journal of Tropical Medicine - Year 2016, Vol 9, Issue 12
Abstract
Objective: To apply lectin affinity chromatography and glycoproteomics-basedLC-MS/MS to preliminarily investigate the possible potential plasma biomarkers ofOpisthorchis viverrini (OV)-associated CCA in OV/dimethylnitrosamine (DMN)-induced CCA hamster model. Methods: Nine Syrian hamsters were divided into 3 groups as follows (n = 3 each): normal (healthy control group); OV group; and OV/DMN group (CCA group). Pooled plasma samples collected from animals in each group at the 6th month post-infection with OV metacercarae were subjected to glycoproteomics analysis. Glycoproteins in the pooled sample from each group were initially isolated by concanavalin A (ConA)-based affinity chromatography. The expression of glycoproteins isolated by both enrichment methods were determined using LC-MS/MS. Results: Among the 24 ConA-binding glycoproteins isolated, two proteins, N-myc downstream regulated gene 1 (NDRG1) and fetuin-B (FETUB) were found up-regulated only in the samples from the OV and control groups, but not in the OV/DMN (CCA) groups. On the other hand, one protein, i.e., NSFL1 cofactor p47 isoform ×3 (NSFL1C) was found only in the samples from OV/DMN (CCA) and control groups, but not in the OV group. The remaining 21 proteins were upregulated in the samples from all groups. Conclusions: NDRG1, FETUB and NSFL1C glycoproteins isolated by ConA-based affinity chromatography could be potential biomarkers for CCA. Plasma samples with negative for NDRG1 and FETUB proteins but positive for NSFL1C are likely to be OVassociated CCA. Nevertheless, this conclusion remains to be confirmed whether this battery test can discriminate OV-associated CCA from other risk factors.
