A post-genomic research field for analysis of low molecular weight compounds in biological systems is called as Metabolomics.

A research article to be published on February 14, 2011 in the World Journal of Gastroenterology addresses this question. The authors used metabolomics, which is based on gas chromatography/mass spectrometry (GC/MS) technology, to study the urinary metabolites expression changes among three mice groups.
This is the first report on urinary metabolomic investigation in gastric cancer using GC/MS. Biomarkers discovered in this study are mainly low molecular weight metabolites, which are difficult to detect by traditional methods. On the basis of this research, the authors believe that urinary metabolomic information investigated by GC/MS might play a significant role in early diagnosis and screening metastasis or recurrence of gastric cancer.
