Known as long non-coding RNAs (lncRNAs), they are essential in regulating tumour metastasis. In gastric carcinoma (GC), lncRNA cytoskeleton regulator () keeps at high levels, but its influences on GC cell proliferation, migration and invasion need further investigation. Hence, the role played by lncRNA in GC was explored in this study. We employed quantitative reverse transcription PCR (RT-qPCR) to determine lncRNA and microRNA (miR)-136-5p levels in GC, Western blot analysis to measure Homeobox C10 (), and Flow cytometry, transwell, and cell counting kit-8 (CCK-8) assays to evaluate the roles played by miR-136-5p and lncRNA in GC cells. Furthermore, bioinformatics analysis and Luciferase assay were carried out to identify the target genes of the two. LncRNA was found to be upregulated in GC cells, and its knockdown inhibited GC cell growth. MiR-136-5p, underexpressed in GC cells, was identified as a target of in modulating GC progression. Moreover, was miR-136-5p's downstream target. Finally, participated in GC progression in vivo. Collectively, modulates the miR-136-5p/HOXC10 axis to accelerate GC progression.
它们被称为长链非编码RNA(lncRNAs),在调节肿瘤转移中至关重要。在胃癌(GC)中,lncRNA细胞骨架调节因子()水平较高,但其对GC细胞增殖、迁移和侵袭的影响尚需进一步研究。因此,本研究探讨了lncRNA在GC中的作用。我们采用定量逆转录PCR(RT-qPCR)来测定GC中lncRNA和微小RNA(miR)-136-5p的水平,通过蛋白质免疫印迹分析来检测同源盒C10(),并使用流式细胞术、Transwell实验和细胞计数试剂盒-8(CCK-8)实验来评估miR-136-5p和lncRNA在GC细胞中的作用。此外,还进行了生物信息学分析和荧光素酶实验以鉴定两者的靶基因。结果发现lncRNA在GC细胞中上调,其敲低可抑制GC细胞生长。miR-136-5p在GC细胞中表达下调,被确定为在调节GC进展过程中是()的一个靶点。此外,()是miR-136-5p的下游靶点。最后,()在体内参与了GC的进展。总的来说,()通过调节miR-136-5p/HOXC10轴来加速GC进展。
