Abstract:BACKGROUND/AIM: Recurrence and metastasis of cancer caused by cancer stem cells (CSCs) is a challenge to overcome.低水平激光疗法是一种抑制其侵入性的新治疗策略。我们已经评估了470 nm蓝色LED的抑制作用关于它们的侵入性确定抗侵入性的分子机制。
材料和方法: 使用MTT和Transwell方法分析了蓝色LED对其生存能力,增殖和入侵的影响。 In addition, the anti-invasiveness effect of blue LED on them was evaluated by zymography, semi-quantitative RT-PCR and western blot analysis.
RESULTS: Irradiation with blue LED at 3 J/cmresulted in inhibition of their viability, proliferation and invasiveness.它们的基质金属蛋白酶2(MMP-2)和MMP-9活性通过蓝色LED辐照减少。半定量RT-PCR也显示出相似的结果。此外,Western印迹分析表明,环氧酶-2(COX-2)和前列腺素E2(PGE2)合成通过LED辐照在CD133-氧直肠CSCS中受到显着抑制插曲: 通过蓝色LED照射对COX-2/PGE2信号通路的下调导致MMP-2和MMP-9的表达降低,从而抑制了CD133COLORORORORORORORORORERERELAL CSC。
