Study TitleMetabolomic analysis of colorectal cancer cells using mass spectrometry
Study SummaryColorectal cancer (CRC) is one of the most prevalent tumors, with a high mortality rate. Nearly half of CRC patients develop metastasis, which accounts for as many as 90% of CRC-related deaths. In the metastasis process, cancer cells exhibit altered dependency on specific metabolic pathways and some of the metabolites discovered might be useful as potential diagnostic biomarkers. To identify metabolic pathway dependencies in CRC metastasis, mass spectrometry-based untargeted metabolomic analysis was performed in two pairs of CRC cell lines with different metastatic abilities. Each pair of cell lines was comprised of primary and metastatic colorectal cancer cell lines (SW480 vs. SW620; HT-29 vs. COLO 205). Relative levels of intracellular metabolites distinguished high-metastatic CRC cells from low-metastatic CRC cells.

Collection ID:CO002423
Collection Summary:Two hours before metabolite extraction, the cell culture medium was replaced with fresh medium. After discarding the medium in each culture dish, the cells were quickly rinsed twice with cold isotonic saline (0.9% NaCl [w/v], 4 °C). Water (1.5 mL) was added to each dish, and then the dishes were stored in a freezer (−80 °C) for 20 min before extraction.
Sample Type:Cultured cells
