Objective: To investigate the expression and role of LINC00052 during glycidyl methacrylate (GMA) -induced malignant transformation of 16HBE cells. Methods: Human bronchial epithelial (16HBE) cells were divided into GMA transformation group and corresponding DMSO control group, and the 10th, 20th and 30th generation cells of each group were collected LncRNA microarrays were used to analysis expression of LINC00052 in different stage of malignant transformation. Bioinformatics analysis was applied and the relative expression of LINC00052 and its potentially target genes was detected by real-time quantification PCR (qPCR) . Results: The results of microarray analysis showed that LINC00052 was up-regulated by 1.32-fold, down-regulated by 1.64-fold and down-regulated by 4.92-fold in the malignant transformation early (P10) , middle term (P20) and late (P30) , respectively, The results of qPCR showed that compared with the DMSO control group, the expression of LINC00052 was up-regulated by 1.55 times, down-regulated by 1.20 times and down-regulated by 2.35 times in P10, P20 and P30, respectively, and the difference was statistically significant (P<0.05) . There was a statistically significant difference in the relative expression of NTRK3 between the GMA transformation group of P10 and P30 generations with the corresponding DMSO control group (P<0.05) . Conclusion: LINC00052 is highly expressed in early time of GMA-induced malignant transformation of 16HBE, and down-regulated in the middle and last stage of malignant transformation and may play a protective role in GMA-induced malignant transformation of 16HBE by influencing the expression of its target gene NTRK3.
目的: 探讨LINC00052在甲基丙烯酸环氧丙酯(GMA)诱导人支气管上皮(16HBE)细胞恶性转化过程中的表达变化及其作用。 方法: 将16HBE细胞分为二甲基亚砜(DMSO)对照组和GMA处理组,收集两组处理后的第10代(P10,前期)、第20代(P20,中期)和第30代(P30,后期)细胞。采用LncRNA芯片分析LINC00052在不同时期的表达改变,借助生物信息学数据库进行靶基因和功能预测,并通过实时荧光定量PCR(qPCR)检测LINC00052和预测靶基因NTRK3的相对表达量。 结果: 芯片结果显示,与对照组比较,LINC00052在转化的P10、P20和P30分别上调1.32倍、下调1.64倍和下调4.92倍。qPCR结果显示,与同期DMSO对照组比较,P10、P20和P30细胞LINC00052的相对表达量分别上调1.55倍、下调1.20倍和下调2.35倍,P10、P30细胞NTRK3的相对表达量分别上调1.37、1.69倍,差异均有统计学意义(P<0.05)。 结论: 在GMA诱导16HBE细胞恶性转化过程中,LINC00052在转化前期表达量上调,中期、后期表达量下调,并可能通过影响靶基因NTRK3的表达发挥抑癌基因的作用。.
