摘要:

目的 探讨长链非编码RNA(lncRNA)肝癌高表达转录本(HULC)在乳头状甲状腺癌(PTC)组织中的表达,以及干扰其表达后对细胞增殖活性和侵袭能力的影响。方法 选取行手术治疗的PTC患者105例,收集术中切除的PTC组织及距离肿瘤边缘2 cm以上的癌旁组织,采用实时荧光定量聚合酶链反应(RT-qPCR)检测HULC的相对表达量。将不同序列分别转染TPC-1细胞,根据转染序列分为si-HULC组(转染HULC的小分子干扰序列)、si-Con组(转染阴性对照序列)、空白组(不作任何处理),检测各组HULC的表达及细胞的增殖活性、侵袭能力。结果 PTC组织中HULC的相对表达量显著高于癌旁组织(P<0.001)。不同肿瘤直径、不同TNM分期、有无淋巴结转移PTC患者癌组织HULC相对表达量差异均有统计学意义(P<0.05),不同年龄、性别、病灶数量和局部侵犯类型PTC患者癌组织HULC相对表达量差异均无统计学意义(P>0.05)。si-HULC组HULC相对表达量、细胞增殖活性及侵袭细胞数均低于si-Con组和空白组(P<0.05),si-Con组与空白组之间差异均无统计学意义(P>0.05)。结论 PTC组织中HULC表达升高,且与肿瘤大小、TNM分期和淋巴结转移有关。干扰HULC表达可抑制TPC-1细胞的增殖活性和侵袭能力。

Abstract:

Objective To investigate the expression of long non-coding RNA(lncRNA)highly up-regulated in liver cancer(HULC) in papillary thyroid carcinoma(PTC) tissues,and to study the effect of interfering with this gene on cell proliferation activity and invasiveness. Methods A total of 105 patients with PTC who underwent surgical treatment were enrolled. The PTC tissues removed during the operation and the adjacent tissues more than 2 cm from the tumor edge were collected. The relative expression level of HULC was determined by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). The TPC-1 cells were transfected with different sequences. According to the different transfection sequences of TPC-1 cells,they were classified into si-HULC group(transfected with small molecule interference sequence of HULC),si-Con group(transfected with negative control sequence) and blank group(not transfected). The expression of HULC,cell proliferation activity and invasiveness in each group were determined. Results The relative expression level of HULC in PTC tissues was higher than that in adjacent tissues(P<0.001). The differences of the expression levels of HULC in PTC tissues with different tumor diameters,TNM stages and lymph node metastasis had statistical significance(P<0.05). There was no statistical significance for the expression levels of HULC in PTC tissues with different ages,sex,the numbers of lesions and the types of local invasion(P>0.05). The relative expression level of HULC,cell proliferation activity and the number of invasive cells in si-HULC group were lower than those in si-Con group and blank group(P<0.05),and there was no statistical significance between si-Con group and blank group(P>0.05). Conclusions The expression of HULC in PTC tissues is increased,and it is related to tumor size,TNM stage and lymph node metastasis. Interfering with HULC expression in TPC-1 cells can inhibit cell proliferation activity and invasiveness.
