MicroRNAs (miRNAs) have been reported to serve as potential biomarkers in bladder cancer and play important roles in cancer progression. This study aimed to investigate the biological role of miR-205-3p in bladder cancer. We showed that miR-205-3p was significantly down-regulated in bladder cancer tissues and cells. Moreover, overexpression of miR-205-3p inhibited bladder cancer progression in vitro. Then we confirmed that GLO1, a downstream target of miR-205-3p, mediated the effect of miR-205-3p on bladder cancer cells. In addition, we found that miR-205-3p inhibits P38/ERK activation through repressing GLO1. Eventually, we confirmed that miR-205-3p inhibits the occurrence and progress of bladder cancer by targeting GLO1 in vivo by nude mouse tumorigenesis and immunohistochemistry. In a word, miR-205-3p inhibits proliferation and metastasis of bladder cancer cells by activating the GLO1 mediated P38/ERK signaling pathway and that may be a potential therapeutic target for bladder cancer.
MicroRNAs (miRNAs) 已被报道可作为膀胱癌的潜在生物标志物，并在癌症进展中发挥重要作用。本研究旨在探讨 miR-205-3p 在膀胱癌中的生物学作用。我们发现 miR-205-3p 在膀胱癌组织和细胞中显著下调。此外，过表达 miR-205-3p 可抑制膀胱癌的体外进展。然后我们证实 GLO1 是 miR-205-3p 的下游靶标，介导了 miR-205-3p 对膀胱癌细胞的作用。此外，我们发现 miR-205-3p 通过抑制 GLO1 来抑制 P38/ERK 的激活。最终，我们通过裸鼠肿瘤生成和免疫组织化学证实，miR-205-3p 通过靶向 GLO1 抑制体内膀胱癌的发生和进展。总之，miR-205-3p 通过激活 GLO1 介导的 P38/ERK 信号通路抑制膀胱癌细胞的增殖和转移，这可能是膀胱癌的潜在治疗靶点。
