摘要:

目的 分析长链非编码RNA(long non⁃coding RNA,lncRNA)淋巴细胞白血病缺失基因1(deleted in lymphocytic leukemia 1,DLEU1)在食管鳞癌(esophageal squamous cell carcinoma,ESCC)中的表达及意义,并进一步研究DLEU1 对ESCC 细胞TE⁃13 增殖、迁移和侵袭的影响。方法 采用实时荧光定量PCR检测ESCC组织和癌旁组织中DLEU1的表达。通过CCK⁃8、划痕试验和Transwell侵袭试验分析DLEU1表达对TE⁃13 增殖、迁移和侵袭的影响。结果 DLEU1 在ESCC 癌组织中的表达较癌旁组织明显升高(P < 0.05)。DLEU1的表达与淋巴结转移和TNM分期相关(P < 0.05),而与患者的年龄、性别、分化程度和浸润深度均无关(P > 0.05)。生存分析示,DLEU1 高表达ESCC 患者的生存时间较低表达患者明显缩短(P < 0.05)。干扰DLEU1表达后TE⁃13的增殖、迁移和侵袭能力显著受抑。结论 DLEU1在ESCC中表达上调,DLEU1的高表达提示预后不良,DLEU1可能对ESCC细胞TE⁃13的增殖、迁移和侵袭具有调节作用,DLEU1有可能成为ESCC治疗的潜在靶点。

Abstract:

Objective To analyze the expression of long⁃chain non⁃coding RNA(lncRNA)lymphocyteleukemia deletion gene 1(DLEU1)in esophageal squamous cell carcinoma(ESCC)and its clinical significance.The effect of DLEU1 on the proliferation,migration and invasion of TE⁃13 was further studied. Methods Real⁃timequantitative polymerase chain reaction was used to detect the expression of DLEU1 in ESCC and adjacent normaltissues. The effects of DLEU1 on the proliferation,migration and invasion of TE⁃13 were analyzed by CCK⁃8,scratchtest and Transwell test. Results The expression of DLEU1 in ESCC was significantly higher than that in adjacentnormal tissues(P < 0.05). The expression of DLEU1 was correlated with lymph node metastasis and TNM stage(P < 0.05),but not with age,gender,degree of differentiation and depth of invasion(P > 0.05). After knockdownof DLEU1 in TE⁃13 cells,cell proliferation,migration and invasion were significantly suppressed. Conclusion The expression of DLEU1 was up⁃regulated in ESCC,and the high expression of DLEU1 suggested a poor progno⁃sis. DLEU1 may have a regulatory effect on the proliferation,migration and invasion of TE⁃13 cells,and it maybecome a potential target for ESCC treatment.
