To investigate the effect of long non-coding RNA URHC on the proliferation, apoptosis and invasion of colorectal cancer cells.
The expression of lncRNA-URHC in tissues and cells was tested by Real-time quantitative PCR. The expression of lncRNA-URHC was down-regulated by RNA interference (siRNA). The Real-time quantitative polymerase chain reaction (PCR) method was used to detect the interference efficiency. Cell counting kit-8 (CCK-8), flow cytometry, and transwell were used to detect the effect of lncRNA-URHC on the proliferation, apoptosis and invasion of colorectal cancer cells. The effect of lncRNA-URHC on epithelial-mesenchymal transition (EMT)-related markers was detected by Western blot.
LncRNA-URHC expression was significantly increased in colorectal cancer cells compared with normal cells, and the expression of lncRNA-URHC in colorectal cancer cells was higher than that in the normal cell. After down-regulated the expression of lncRNA-URHC, the proliferation and invasion of colorectal cancer cells were decreased, while cells apoptosis was promoted. Down-regulation of lncRNA-URHC could enhance the expression of E-cadherin and reduce the expression of N-cadherin, vimentin and snail.
Down-regulation of lncRNA-URHC can inhibit the progression of colorectal cancer.
研究长链非编码 RNA URHC 对结直肠癌细胞增殖、凋亡和侵袭的影响。
采用实时定量 PCR 检测组织和细胞中 lncRNA-URHC 的表达。采用 RNA 干扰(siRNA)下调 lncRNA-URHC 的表达。实时定量聚合酶链反应(PCR)检测 lncRNA-URHC 的干扰效率。细胞计数试剂盒-8(CCK-8)、流式细胞术和 Transwell 检测 lncRNA-URHC 对结直肠癌细胞增殖、凋亡和侵袭的影响。Western blot 检测 lncRNA-URHC 对上皮间质转化(EMT)相关标志物的影响。
与正常细胞相比,结直肠癌细胞中 lncRNA-URHC 的表达明显升高,且结直肠癌细胞中的表达高于正常细胞。下调 lncRNA-URHC 的表达后,结直肠癌细胞的增殖和侵袭能力降低,而细胞凋亡增加。下调 lncRNA-URHC 可增强 E-钙黏蛋白的表达,降低 N-钙黏蛋白、波形蛋白和 snail 的表达。
下调 lncRNA-URHC 可抑制结直肠癌的进展。
