Abstract

The effect of 2-deoxy-d-glucose (2-DDG) on C3H mouse fibrosarcoma (FSall) was studied. Metabolic status, especially for energy metabolism, was studied using in vivo 31P-MRS, proliferative capacity was observed on flow cytometry (FC) and growth rate was measured after transplantation of 106 viable tumor cells in the dorsum of foot of C3Hf/Sed mice. One gram of 2-DDG per kg of body weight was injected intraperitoneally on 12th day of implantation. Average tumor size on 12th day of implantation was 250mm3. Growth rate of FSall tumor was measured by tumor doubling time between tumor age 5-12 days was 0.84 days with slope 0.828 and tumor doubling time between tumor age 13-28 days was 3.2 days with slope 0.218 in control group. After 2-DDG injection, tumor doubling time was elongated to 5.1 days with slope 0.136. The effect of 2-DDG studied in vivo 31P-MRS suggested that the increase of phosphomonoester (PME) and inorganic phosphate (Pi) by increasing size of tumor, slowed down after 2-DDG injection. Flow cytometry showed significantly increased S-phase and G2+M phase fraction suggesting increased proliferative capacity of tumor cells in the presence of 2-DDG. Authors observed an interesting effect 2-DDG on FSall tumor and attempt to utilize as an adjunct for radiotherapy.
