“The ERH gene regulates migration and invasion in 5637 and T24 bladder cancer cells”

“ERH基因調控5637和T24膀胱癌細胞的遷移和侵襲”

Abstract：

Background: This study aimed to determine whether the enhancer of the rudimentary homolog (ERH) gene regulates cell migration and invasion in human bladder urothelial carcinoma (BUC) T24 cells and the underlying mechanism.

Methods: First, we knocked down ERH in BUC T24 and 5637 cells by shRNA and then used wound healing cell scratch migration assays, transwell cell migration assays, transwell cell invasion chamber experiments and nude mouse tail vein transfer assays to determine the migration and invasion ability after ERH was knocked down. Moreover, we used gene expression profiling chip analysis and further functional experiments to explore the possible mechanism through which ERH knockdown downregulated metastasis ability in T24 cells.

Results: Wound healing cell scratch migration assays, transwell cell migration assays, transwell cell invasion chamber experiments and nude mouse tail vein transfer assays all showed that the metastasis ability was significantly inhibited in human BUC T24 and 5637 cells with ERH knockdown. A gene expression profiling chip analysis in T24 cells showed that the MYC gene may be an important downstream target of the ERH gene, and the functional experiments showed that MYC is a functional target of ERH in BUC T24 cells.

Conclusion: ERH knockdown could inhibit the metastasis of BUC T24 cells in vitro and in vivo. This study further explored the mechanism of the ERH gene in the metastasis of the T24 human bladder cancer cell line and found that ERH may regulate MYC gene expression. The results of this research provide a basis for the clinical application of ERH as a potential target for BUC treatment.

摘要：

背景

本研究旨在探討ERH基因增強子是否調控人膀胱尿路上皮癌(BUC) T24細胞的遷移和侵襲及其機制。

方法

首先，研究人員通過shRNA敲除BUC T24和5637細胞中的ERH，然后通過傷口愈合細胞劃痕遷移實驗、transwell細胞遷移實驗、transwell細胞侵襲室實驗和裸鼠尾靜脈移植實驗來測定ERH敲除后的遷移和侵襲能力。此外，研究人員通過基因表達譜芯片分析和進一步的功能實驗，探討ERH敲低下調T24細胞轉移能力的可能機制。

結果

傷口愈合細胞劃痕遷移實驗、transwell細胞遷移實驗、transwell細胞侵襲室實驗和裸鼠尾靜脈轉移實驗均表明，ERH敲低的人BUC T24和5637細胞的轉移能力明顯受到抑制。T24細胞基因表達譜芯片分析顯示MYC基因可能是ERH基因的重要下游靶點，功能實驗顯示MYC在BUC T24細胞中是ERH的功能靶點。

結論

ERH敲低可抑制BUC T24細胞的體內外轉移。本研究進一步探討了ERH基因在T24人膀胱癌細胞系轉移中的作用機制，發現ERH可能調控MYC基因的表達。本研究結果為ERH作為治療BUC的潛在靶點的臨床應用提供了依據。
