摘要
目的:探讨长链非编码RNA(LncRNA)HULC在结直肠癌(CRC)中的表达及其预后价值。方法:利用实时定量PCR方法检测HULC在结直肠正常黏膜上皮细胞NCM460和CRC细胞,以及在35例CRC组织和配对癌旁组织中的表达情况,并分析其与CRC患者预后的关系。结果:HULC在CRC细胞内的表达水平显著高于NCM460,在CRC组织中的相对表达量为6.801±0.294(n=35),癌旁组织中为3.883±0.309(n=35),差异有统计学意义(P〈0.05)。Kaplan-Meier生存分析显示HULC低表达组CRC患者术后的生存时间明显高于高表达组,差异有统计学意义(P〈0.05)。结论:HULC在CRC细胞和组织内过表达,可作为CRC预后判断的一个潜在靶点。
Objective: To investigate the relative expression of the long noncoding RNA (lncRNA) HULC in colorectal cancer (CRC) cells and tissues, and its prognostic value. Methods: Quantita- tive real-time PCR (qRT-PCR) was used to detect the relative expression of lnCRNA HULC in NCM460, the normal colorectal mucosa epithelial cell, and CRC cells, as well as 35 cases of CRC tissues and their adjacent normal specimens. The relationship between HULC and the prognosis of CRC patients was analyzed by SPSS 19.0 software. Results: The expression of HULC in CRC ceils was much higher than that of NCM460. The relative expression of HULC was 6. 801 ± 0.294 (n=35) in CRC tissues, while 3. 883-60. 309 in normal specimens (P〈0.05). The in- creased level of HULC was associated with poor prognosis and shorter survival by KaplawMeier survival analysis. Conclusion: HULC expression is over-expressed in CRC cells and tissues and may serve as a potential target for clinical prognostic analysis.
