目的

探究长链非编码RNA LINC00839(LINC00839)调节微小RNA-17-5p(miR-17-5p)/丝氨酸/苏氨酸蛋白激酶1(WEE1)轴对结直肠癌(CRC)细胞增殖、凋亡和迁移的影响。

方法

检测CRC 细胞系中LINC00839、miR-17-5p、WEE1 mRNA 表达水平,筛选最佳细胞系,将LS513 细胞分为对照组(Control组)、LINC00839 敲低阴性对照组(si-NC组)、LINC00839敲低组(si-LINC00839组)、LINC00839 敲低+miR-17-5p 抑制表达阴性对照组(si-LINC00839+NC inhibitor组)、LINC00839 敲低+miR-17-5p 抑制表达组(si-LINC00839+miR-17-5p inhibitor组)。qRT-PCR 检测细胞中LINC00839、miR-17-5p 和WEE1 mRNA 表达水平;双荧光素酶报告基因实验验证LINC00839、miR-17-5p 和WEE1 之间的靶向关系;MTT 检测细胞活力;Edu 检测细胞增殖;划痕实验检测细胞的迁移能力;流式细胞仪检测细胞凋亡;Western blot 检测WEE1、PCNA、Bax、Bcl-2、caspase-3、E-cadherin、N-cadherin 蛋白水平。

结果

在CRC 细胞系中LINC00839、WEE1 mRNA高表达,miR-17-5p 低表达,选择LS513 细胞进行实验。双荧光素酶报告基因实验证实miR-17-5p与LINC00839、WEE1 存在靶向关系,LINC00839 敲低可上调miR-17-5p 表达,下调WEE1 表达。敲低LINC00839 能显著降低LS513 细胞活力、Edu 阳性率、划痕愈合率及PCNA、Bcl-2、N-cadherin和WEE1 蛋白表达(P<0.05),显著增加Bax、caspase-3、E-cadherin 蛋白表达(P<0.05)。抑制miR-17-5p 的表达能逆转LINC00839 敲低对LS513 细胞恶性生物学行为的抑制作用(P<0.05)。

结论

LINC00839 在CRC 细胞中上调,敲低LINC00839 可能通过调控miR-17-5p/WEE1 轴抑制CRC细胞增殖和迁移,促进细胞凋亡。

Objective

To investigate the effects of long non-coding RNA LINC00839 on the proliferation,apoptosis,and migration of colorectal cancer (CRC) cells by regulating the microRNA-17-5p(miR-17-5p)/serine/threonine protein kinase 1 (WEE1) axis.

Methods

The expression levels of LINC00839,miR-17-5p,and WEE1 mRNA in CRC cell lines were detected to screen the optimal cell line.LS513 cells were separated into Control group,LINC00839 knockdown negative control group (si-NC group),LINC00839 knockdown group (si-LINC00839 group),LINC00839 knockdown+miR-17-5p inhibition negative control group (si-LINC00839+NC inhibitor group),and LINC00839 knockdown+miR-17-5p inhibitor expression group (si-LINC00839+miR-17-5p inhibitor group). qRT-PCR was applied to detect the expression levels of LINC00839,miR-17-5p,and WEE1 mRNA in cells. Dual luciferase reporter gene experiment was applied to verify the targeting relationship between LINC00839,miR-17-5p,and WEE1. MTT was applied to detect cell viability. Edu was applied to detect cell proliferation. Scratch experiment was applied to detect the migration ability of cells. Flow cytometry was applied to detect cell apoptosis. Western blot was applied to detect protein levels of WEE1,PCNA,Bax,Bcl-2,caspase-3,E-cadherin,and N-cadherin.

Results

In the CRC cell line,LINC00839 and WEE1 mRNA were highly expressed,while miR-17-5p was low expressed. LS513 cells were selected for the experiment. Dual luciferase reporter gene experiment confirmed a targeted relationship between miR-17-5p and LINC00839,WEE1. Knocking down LINC00839 up-regulated miR-17-5p expression and down-regulated WEE1 expression. Knocking down LINC00839 greatly reduced LS513 cell viability,Edu positive rate,scratch healing rate,and expression of PCNA,Bcl-2,N-cadherin,and WEE1 proteins (P<0.05),while greatly increased the expression of Bax,caspase-3,and E-cadherin proteins (P<0.05). Inhibiting the expression of miR-17-5p was able to reverse the inhibitory effect of LINC00839 knockdown on the malignant biological behavior of LS513 cells (P<0.05).

Conclusion

LINC00839 is up-regulated in CRC cells,and knocking down LINC00839 may inhibit CRC cell proliferation and migration by regulating the miR-17-5p/WEE1 axis,promoting cell apoptosis.
