| Research Abstract |
We investigated GABA system in human cartilage tumors to establish new methods of differential diagnosis and treatment. We detected strongly GAD65 mRNA in human cartilage tumors and chondrosarcoma cells using real time PCR. BrdU incorporation of the cells treated with GABA and GABA receptor agonist was significantly increased, while that of the cells treated with GABA receptor antagonist was significantly inhibited (p>0.01). Our findings indicate that GABA system is related to the proliferation process in human cartilage tumors.
