Research Abstract |
Human squamous cancer cells (TE-4) were inoculated subcutaneously in the bilateral back of BALB/c nude mice. Unilateral tumors or bilateral tumors were resected 3 weeks after inoculation as surgical models. And 5-FU (25mg/kg or 50mg/kg) was injected intraperitoneously 4 times 3 weeks after inoculation as chemotherapy models. Blood was collected and animals were sacrificed 5 weeks after inoculation. Serum was processed and used for DNA measurement using a real time PCR method. DNA concentrations (Alu 247 and Alu115) correlated with tumor volumes. Serum DNA seems to be a good biomarker for cancer staging and evaluating chemotherapeutic effects.
