| Study Title | Nucleotide metabolism of tumor interstitial fluid in one murine model of pancreatic cancer |
| Study Summary | The experiment focus on the nucleotide metabolism of tumor interstitial fluid in one murine model of pancreatic cancer. Briefly, KPC FC1245 cells were genetically engineered using doxycycline inducible CRISPR/Cas9 system platform to target specifically cytidine deaminase (sgCda). sgCda and the control sgNT were then orthotopically injected in the head of the pancreas of 8-10 weeks old C57BL/6J female mice. When the tumor weight reached approximately 0.2-0.4g, mice were sacrificed and tumor interstitial fluid was collected as reported in the Collection section of this study. Standard curves for glutamine, cytidine, uridine, glucose, UTP and UDP were prepared and extracted along with the interstitial fluid samples. The concentrations of glutamine, cytidine, uridine, UDP and UTP were measured by LC-MS, and glucose was measured by GC-MS. A decrease in uridine content, and accordingly in UDP and UTP, and a concomitant accumulation of cytidine was observed in sgCda tumors. On the other hand, no differences were observed in glucose and glutamine abundance. |
