Abstract

INTRODUCTION

Lnc712 has been characterized as an oncogenic lncRNA in breast cancer. This study aimed to investigate the role of Lnc712 in osteosarcoma (OS).

METHODS

OS and paired non-tumor tissues were collected from 58 OS patients. Expression of Lnc712 and miR-129-5p in paired tissue samples was determined by RT-qPCR. Lnc712 and miR-129-5p expression was achieved in OS cells to study the interaction between them. Cell proliferation was analyzed by CCK-8 assay.

RESULTS

Lnc712 was upregulated in OS and was inversely correlated with miR-129-5p. In OS cells, Lnc712 overexpression failed to significantly affect miR-129-5p, while miR-129-5p overexpression led to downregulated Lnc712. Cell proliferation showed that Lnc712 overexpression resulted in increased cell proliferation rate. MiR-129-5p overexpression played an opposite role and reversed the effect of Lnc712 overexpression.

DISCUSSION

MiR-129-5p may suppress cell proliferation of OS by down-regulating Lnc712.

摘要

引言

Lnc712已被证实为乳腺癌中的一种致癌长链非编码RNA。本研究旨在探究Lnc712在骨肉瘤（OS）中的作用。

方法

收集58例骨肉瘤患者的骨肉瘤组织及配对的非肿瘤组织。采用RT-qPCR检测配对组织样本中Lnc712和miR-129-5p的表达。在骨肉瘤细胞中实现Lnc712和miR-129-5p表达，以研究它们之间的相互作用。通过CCK-8法分析细胞增殖情况。

结果

Lnc712在骨肉瘤中上调，且与miR-129-5p呈负相关。在骨肉瘤细胞中，Lnc712过表达对miR-129-5p无显著影响，而miR-129-5p过表达导致Lnc712下调。细胞增殖实验表明，Lnc712过表达导致细胞增殖率增加。miR-129-5p过表达则起相反作用，逆转了Lnc712过表达的影响。

讨论

miR-129-5p可能通过下调Lnc712抑制骨肉瘤细胞增殖。
