摘要: 目的 研究环状RNA脂肪非典型钙黏蛋白1(CircFAT1)调节miR-296-3p/微管关联蛋白RP/EB家族成员1(MAPRE1)轴对鼻咽癌细胞增殖、凋亡和放疗敏感性的影响。 方法 以实时荧光定量PCR和免疫印迹法检测鼻咽上皮细胞NP69、人鼻咽癌细胞株CNE2及其放射线抵抗细胞CNE2-RR中CircFAT1、miR-296-3p、MAPRE1表达。将体外培养的CNE2细胞随机分为对照组、CircFAT1敲低组、阴性对照组、CircFAT1敲低+miR-296-3p inhibitor组,分组转染后以实时荧光定量PCR和免疫印迹法检测各组CNE2细胞CircFAT1、miR-296-3p、MAPRE1表达;以CCK-8法、5-乙炔基-2-脱氧尿苷(Edu)染色与流式细胞实验检测各组CNE2细胞增殖、凋亡。将体外培养的CNE2-RR细胞随机分为对照组、放射组、放射+阴性对照组、放射+CircFAT1敲低组、放射+CircFAT1敲低+miR-296-3p inhibitor组,分组转染后以实时荧光定量PCR和免疫印迹法检测各组CNE2-RR细胞CircFAT1、miR-296-3p、MAPRE1表达;以CCK-8法、Edu染色与流式细胞实验检测各组CNE2-RR细胞增殖、凋亡。以双荧光素酶报告基因实验检测CNE2-RR中CircFAT1对miR-296-3p的靶向调节与miR-296-3p对MAPRE1的靶向调节。 结果 与NP69细胞相比,CNE2、CNE2-RR细胞CircFAT1表达、MAPRE1 mRNA与蛋白表达升高(P<0.05),miR-296-3p表达降低(P<0.05);与CNE2细胞相比,CNE2-RR细胞CircFAT1表达、MAPRE1 mRNA与蛋白表达升高(P<0.05),miR-296-3p表达降低(P<0.05)。与对照组相比,CircFAT1敲低组CNE2细胞CircFAT1表达、MAPRE1 mRNA与蛋白表达、存活率、增殖率降低(P<0.05),miR-296-3p表达、凋亡率升高(P<0.05);阴性对照组CNE2细胞各指标无明显变化(P>0.05),miR-296-3p inhibitor可逆转敲低CircFAT1对CNE2细胞各指标的影响。与对照组、放射组分别相比,放射+CircFAT1敲低组CNE2-RR细胞CircFAT1表达、MAPRE1 mRNA与蛋白表达、存活率、增殖率降低(P<0.05),miR-296-3p表达、凋亡率升高(P<0.05);放射组、放射+阴性对照组CNE2-RR细胞各指标无明显变化(P>0.05),miR-296-3p inhibitor可逆转敲低CircFAT1对放射处理下CNE2-RR细胞各指标的影响。CircFAT1可靶向下调CNE2-RR细胞miR-296-3p表达,而miR-296-3p可靶向下调CNE2-RR细胞MAPRE1表达。 结论 敲低CircFAT1可通过上调miR-296-3p而降低MAPRE1表达,从而抑制鼻咽癌细胞增殖,促进其凋亡并增强其放射敏感性。
