Description

Objective: To study the effects of brachytherapy on the gene expressions of elastin and elastase in cultured rat vascular smooth muscle cells (VSMCs). Methods: Rat VSMCs cultured in DMEM containing 10% FBS were irradiated by 60Co γ-rays at 0, 7, 14, 28 Gy respectively. Then mRNA levels of elastin and elastase were determined by reverse transcription competitive PCR(RT-PCR). Results: Brachytherapy inhibited the expressions of elastase. Elastase mRNA decreased 25.3% and 50.1% in VSMC irradiated with 14, 28 Gy, respectively (P<0.05). The elastin mRNA level increased 80.7% and 102.3% in VSMC irradiated with 14, 25 Gy, respectively (P<0.05). Conclusion: Brachytherapy inhabits the expressions of elastase and increased elastin in VSMC cells
