Study TitleFunctional metabolic molecule were identified as novel therapeutic targets to facilitate gemcitabine treatment against pancreatic cancer (Tumor tissues metabolomics)
Study SummaryWith the development of frontier technologies in system biology, traditional omics-drove phenotypic studies are insufficient to decipher the diseases. Therefore, for a thorough understanding of the molecular mechanisms of diseases to investigate novel drug targets, traditional phenotypic studies must be broken through to the functional exploration of molecules. Meanwhile, the intuitive role of small molecule compounds (metabolites) in pathogenesis, precision diagnosis and therapy are gradually recognized compared to macromolecules such as DNA, RNA and proteins. Therefore, we pioneeringly proposed Spatial Temporal Operative Real Metabolomics (STORM) strategy that established a relationship between metabolic phenotypes and functions to accurately character abnormal metabolisms and further identify operative functional molecules as novel therapeutic targets. Here, given the difficulty of pancreatic cancer (PC) treatment and the high resistance of clinical drugs, we were committed to explore new targets and drugs of pancreatic cancer from a small molecular functional perspective via STORM strategy. Fortunately, based on targeted metabolomics, we found that gemcitabine, one of the most effective clinical anti-PC drugs, served as a dual modulator that promote the accumulation of functional metabolic molecules in purine metabolism to activate down-streamed kinases. And the quantitative consequences of related enzymes annotated the unique molecular mechanisms of purine metabolism regulations by gemcitabine. Collectively, we broadened the cognitions of gemcitabine in tumor inhibition, providing potential strategies for treating PC with small molecules modification. Even more importantly, with the integration of multiple frontier technologies, the STORM strategy has proven to be well adapted to the phenotypic era of functional molecules devoted to innovate molecule mechanism annotation and therapeutic discovery.

Sample Preparation:

Sampleprep ID:SP002212
Sampleprep Summary:100-130 mg tissue samples tumor tissues have to be broken by oscillation with 60HZ and 2 minutes in iced 80% methanol solution (mixed with internal standard 0.001mg/ml 4-chloro-DL-phenylalanine). centrifuging at 20,000 g for 10 min at 4 °C, and mixing the supernatants with 800 μL ice-cold acetonitrile. Then the supernatant obtained by centrifugation was filtered through a 0.22 µm organic phase membrane, blown dry in nitrogen, reconstituted in 100 µL of water and transferred to vials for metabolomics assay.
