This West Coast Metabolomics Center pilot and feasibility project was granted to Johanna Lampe (Fred Hutchinson Cancer Research Center at Univ. of Washington, Seattle). In the current investigation, unbiased profiling of the metabolome and lipidome of adipose tissue samples (visceral(VAT) and subcutaenous (SAT)) and serum of 50 CRC patients, including stages I-IV, from the Fred Hutchinson Cancer Center (Seattle,WA) and the German Cancer Research Center (Heidelberg, Germany) was conducted. The lipidome and metabolome of adipose tissue (VAT/SAT) and serum were analyzed using established UPLC-QTOFMS analysis and GC-TOFMS analyses, respectively.\u00a0
The primary objectives of this project were to 1) compare the metabolome and lipidome of\u00a0matched\u00a0VAT\u00a0and SAT adipose tissue of n=50 Colorectal Cancer Cell (CRC) patients, 2) characterize the associations between the lipidome and metabolome in adipose tissue (VAT/SAT) and serum of n=50 CRC patients and 3) test the associations between the lipidome/metabolome of VAT and serum with the tumor stage of CRC patients.
