背景:叉头盒F2,叉头盒转录因子超家族的成员,在几种类型的癌症中起着重要作用。然而,ForkheadboxF2在结直肠癌进展中的作用机制尚不清楚.PRUNE2与前列腺癌密切相关,神经母细胞瘤,胶质母细胞瘤,还有黑色素瘤.叉头框F2和PRUNE2在结直肠癌中的关系仍然未知。方法:我们使用细胞计数试剂盒-8,集落形成,研究了分叉盒F2上调对体外结直肠癌细胞行为的影响,流式细胞术,Transwell,逆转录定量聚合酶链反应和蛋白质印迹分析。建立裸鼠异种移植物以研究叉头盒F2上调对结直肠癌细胞生长的影响。进行双荧光素酶报告基因测定以确认PRUNE2转录的叉头框F2调节。在具有叉头盒F2上调和PRUNE2敲低的细胞中进行了一系列体外测定,以阐明叉头盒F2对结直肠癌中PRUNE2转录的功能和调节作用。结果:与邻近组织相比,叉头盒F2在结直肠癌组织中下调。叉头盒F2过表达在体外和体内显着抑制结直肠癌细胞的增殖和侵袭。此外,叉头框F2直接靶向PRUNE2以促进其在结直肠癌细胞中的转录。此外,PRUNE2介导叉头盒F2调节结直肠癌细胞的增殖和侵袭。此外,我们证明了结直肠癌组织中ForkheadboxF2和PRUNE2mRNA水平之间的显着正相关。结论:这些结果表明,叉头框F2和PRUNE2的组合可能作为结直肠癌的预后生物标志物,并且叉头框F2的上调通过上调PRUNE2抑制结直肠癌细胞的增殖和侵袭。
Background: Forkhead box F2, a member of the Forkhead box transcription factor superfamily, plays an important role in several types of cancer. However, the mechanisms of Forkhead box F2 in the progression of colorectal cancer remain unclear.
PRUNE2 is closely associated with prostate cancer, neuroblastoma, glioblastoma, and melanoma. The relationship between Forkhead box F2 and
PRUNE2 in colorectal cancer remains unknown. Method: We investigated the effects of Forkhead box F2 upregulation on colorectal cancer cell behavior in vitro using Cell Counting Kit-8, colony formation, flow cytometry, Transwell, reverse transcription quantitative polymerase chain reaction and Western blot analyses. Nude mouse xenografts were established to investigate the effect of Forkhead box F2 upregulation on the growth of colorectal cancer cells. Dual-luciferase reporter assays were performed to confirm the Forkhead box F2 regulation of PRUNE2 transcription. A series of in vitro assays was performed in cells with Forkhead box F2 upregulation and
PRUNE2 knockdown to elucidate the function and regulatory effects of Forkhead box F2 on PRUNE2 transcription in colorectal cancer. Results: Forkhead box F2 was downregulated in colorectal cancer tissues compared with adjacent tissues. Forkhead box F2 overexpression significantly suppressed the proliferation and invasion of colorectal cancer cells in vitro and in vivo. Moreover, Forkhead box F2 directly targeted
PRUNE2 to promote its transcription in colorectal cancer cells. Furthermore, PRUNE2 mediated the Forkhead box F2-regulated proliferation and invasion of colorectal cancer cells. Additionally, we demonstrated a significant positive correlation between Forkhead box F2 and
PRUNE2 mRNA levels in colorectal cancer tissues. Conclusion: These results indicated that Forkhead box F2 and PRUNE2 in combination may serve as a prognostic biomarker for colorectal cancer and that Forkhead box F2 upregulation inhibits the proliferation and invasion of colorectal cancer cells by upregulating PRUNE2.
