Study Title | NMR-based Metabolomics for CRC Diagnosis |
Study Type | Disease Diagnosis |
Study Summary | Despite the fact that colorectal cancer (CRC) is one of the most prevalent and deadly cancers in the world, the development of improved and robust biomarkers to enable screening, surveillance, and therapy monitoring of CRC continues to be evasive. In particular, patients with colon polyps are at higher risk of developing colon cancer; however, noninvasive methods to identify these patients suffer from poor performance. In consideration of the challenges involved in identifying metabolite biomarkers in individuals with high risk for colon cancer, we have investigated NMR-based metabolite profiling in combination with numerous demographic parameters to investigate the ability of serum metabolites to differentiate polyp/CRC patients from healthy subjects. We also investigated the effect of disease risk on different groups of biologically related metabolites. Our study may explain some of the challenges and promise a novel avenue for future metabolite profiling methodologies. |

Sample Preparation:
Sampleprep ID: | SP000313 |
Sampleprep Summary: | Each frozen serum sample was thawed and vortexed; 530 µL aliquots were mixed with 5 µL sodium azide solution (5% in H2O). The resulting solution was centrifuged, and 530 µL was transferred to a 5 mm NMR tube. A coaxial capillary containing 60 µL TSP (20.9 nmol) in D2O was placed into the NMR tube to serve as a chemical shift and quantitative reference. The samples were randomized before performing the NMR experiments. |
