摘要: 目的:探讨长链非编码RNA LINC00844在肝细胞肝癌组织中的表达水平及其作用。方法:采用实时荧光定量PCR(qRT-PCR)检测12对临床肝细胞肝癌组织及相应癌旁组织中LINC00844表达水平;通过携带LINC00844基因的慢病毒与不携带外源性基因的慢病毒感染的方式构建HepG2和HCCLM9细胞系过表达LINC00844组(LV-LINC00844)和对照组(LV-NC),并通过荧光显微镜及qRT-PCR检测过表达的效率,利用细胞计数试剂盒(CCK-8)和Transwell分析LINC00844对HepG2和HCCLM9细胞增殖及迁移的影响。结果:在12对临床标本中,11对肝细胞肝癌组织中LINC00844的表达明显低于癌旁组织(P<0.01);成功构建了过表达LINC00844的HepG2和HCCLM9细胞系;过表达LINC00844可以抑制HepG2和HCCLM9细胞的增殖及迁移能力(P<0.01)。结论:LINC00844可以抑制细胞的增殖及迁移参与肝细胞肝癌的发生发展,LINC00844可能是肝细胞肝癌的一个潜在的生物标记物及治疗靶点。

Abstract: AIM: To explore the expression level of long non-coding RNA(lncRNA) LINC00844 and its effect on hepatocellular carcinoma (HCC). METHODS: The expression of LINC00844 was detected by real-time quantitative PCR (qRT-PCR) in 12 pairs of HCC tissues and paired paracancerous tissues. The LINC00844 group (LV-LINC00844) and the control group (LV-NC) in HepG2 and HCCLM9 cell lines were constructed by lentivirus carrying LINC00844 gene and lentivirus without LINC00844 gene. The effects of over-expressed LINC00844 on proliferation and migration of HepG2 and HCCLM9 cell lines were detected by cell counting kit-8 (CCK-8) assay and transwell assay, respectively.RESULTS:Among 12 pairs of clinical samples, the expression of LINC00844 in 11 hepatocellular carcinoma tissues was significantly lower than that in paired paracancerous tissues detected by qRT-PCR (P<0.01). Over-expressed HepG2 and HCCLM9 cell lines were successfully constructed. Furthermore, in vitro experiments demonstrated that enhanced expression LINC00844 inhibted the proliferation and migration of HepG2 and HCCLM9 (P<0.01). CONCLUSION: LINC00844 can inhibit the proliferation and migration in HepG2 and HCCLM9 cell lines. LINC008444 may be a potential promising prognostic biomarker and therapeutic target for HCC.
