2,6-diisopropylphenol (propofol) is a commonly used intravenous anesthetic drug, which has been reported to serve an antitumor role in human cancers. The current study aimed to assess the effects of propofol on the biological behaviors of human bladder cancer cells and to elucidate its potential molecular mechanism. The results of MTT, wound healing and Matrigel invasion assays demonstrated that propofol significantly inhibited the viability, migration and invasion of bladder cancer T24 cells . Reverse transcription-quantitative PCR and western blotting revealed that propofol decreased the expression levels of microRNA (miR)-10b and increased the expression levels of homeobox D10 (HOXD10) in T24 cells. Luciferase reporter assay revealed that HOXD10 was a direct target of miR-10b in T24 cells. T24 cells transfected with a miR-10b mimic significantly reduced the mRNA and protein expression levels of HOXD10. In addition, overexpression of miR-10b partly reversed the inhibitory effect of propofol on T24 cell viability, migration and invasion induced by upregulation of HOXD10. In summary, the present study focused on the role of propofol in the treatment of bladder cancer and demonstrated that propofol may serve a tumor-suppressive role and control cell viability, migration and invasion of T24 cells by targeting the miR-10b/HOXD10 signaling pathway, which indicated that propofol may be used as an effective therapeutic drug for the treatment of bladder cancer.
2,6-二异丙基苯酚(丙泊酚)是一种常用的静脉麻醉药物,据报道其在人类癌症中发挥抗肿瘤作用。本研究旨在评估丙泊酚对人膀胱癌细胞生物学行为的影响,并阐明其潜在的分子机制。MTT、伤口愈合和基质胶侵袭实验结果表明,丙泊酚显著抑制膀胱癌细胞T24的活力、迁移和侵袭。逆转录-定量PCR和蛋白质印迹分析显示,丙泊酚降低了T24细胞中微小RNA(miR)-10b的表达水平,并增加了同源盒D10(HOXD10)的表达水平。荧光素酶报告基因检测显示,HOXD10是T24细胞中miR-10b的直接靶标。用miR-10b模拟物转染的T24细胞显著降低了HOXD10的mRNA和蛋白质表达水平。此外,miR-10b的过表达部分逆转了丙泊酚对由HOXD10上调诱导的T24细胞活力、迁移和侵袭的抑制作用。综上所述,本研究聚焦于丙泊酚在膀胱癌治疗中的作用,并证明丙泊酚可能发挥肿瘤抑制作用,并通过靶向miR-10b/HOXD10信号通路控制T24细胞的活力、迁移和侵袭,这表明丙泊酚可能作为治疗膀胱癌的有效治疗药物。
