Epithelial mesenchymal transformation plays a crucial role in the metastasis of bladder cancer, which makes bladder cancer difficult to cure. Bladder cancer is the most common malignancy of the urinary system, and distant metastasis is the leading cause of death. Therefore, finding a bioactive drug that can specifically inhibit epithelial mesenchymal transformation may be a new direction for bladder cancer treatment in the future. Thymoquinone (TQ), the major active compound isolated from black seed oil (Nigella sativa), has been reported to exhibit anti-inflammatory and anticancer abilities. TQ can exhibit its antitumor effect by inhibiting the proliferation and metastasis of cancer cells. However, the underlying mechanism of TQ as a tumor inhibitor in bladder cancer remains poorly understood. First, in this research, we demonstrate that TQ can reverse EMT by upregulating epithelial markers, such as E-cadherin, and downregulating mesenchymal markers, such as N-cadherin and vimentin. Furthermore, we demonstrate that TQ can suppress the activation of the Wnt/β-catenin signaling pathway and inhibit the expression of β-catenin target genes, such as MYC, Axin-2, MMP7, CyclinD1 and MET, which play crucial roles in EMT and cancer progression. Additionally, we demonstrate that TQ can inhibit the growth of xenografts and restrict the formation of tumor metastatic foci in the lung. Taken together, our findings confirm the antimetastatic effect of TQ in bladder cancer cells for the first time and also provide new evidence for the development of TQ as a novel treatment for metastatic bladder cancer.

胸腺醌可通过Wnt /β-catenin信号通路逆转EMT,从而抑制膀胱癌细胞的侵袭和转移。

上皮间质转化在膀胱癌的转移中起关键作用,这使膀胱癌难以治愈。膀胱癌是泌尿系统最常见的恶性肿瘤,远处转移是死亡的主要原因。因此,寻找一种可以特异性抑制上皮间质转化的生物活性药物可能是未来膀胱癌治疗的新方向。据报道,从黑子油(紫薇)中分离出的主要活性化合物胸腺醌(TQ)具有抗炎和抗癌的能力。TQ可通过抑制癌细胞的增殖和转移来发挥其抗肿瘤作用。但是,TQ作为膀胱癌肿瘤抑制剂的潜在机制仍然知之甚少。首先,在这项研究中 我们证明TQ可以通过上调上皮标记物(例如E-钙粘着蛋白)和下调间充质标记物(例如N-钙粘着蛋白和波形蛋白)来逆转EMT。此外,我们证明TQ可以抑制Wnt /β-catenin信号通路的激活并抑制β-catenin靶基因的表达,例如MYC,Axin-2,MMP7,CyclinD1和MET,它们在EMT中起关键作用和癌症进展。此外,我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。并下调间充质标志物,例如N-钙黏着蛋白和波形蛋白。此外,我们证明TQ可以抑制Wnt /β-catenin信号通路的激活并抑制β-catenin靶基因的表达,例如MYC,Axin-2,MMP7,CyclinD1和MET,它们在EMT中起关键作用和癌症进展。此外,我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。并下调间充质标志物,例如N-钙黏着蛋白和波形蛋白。此外,我们证明TQ可以抑制Wnt /β-catenin信号通路的激活并抑制β-catenin靶基因的表达,例如MYC,Axin-2,MMP7,CyclinD1和MET,它们在EMT中起关键作用和癌症进展。此外,我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。我们证明TQ可以抑制Wnt /β-catenin信号通路的激活并抑制β-catenin靶基因的表达,例如MYC,Axin-2,MMP7,CyclinD1和MET,它们在EMT和癌症中起关键作用进展。此外,我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。我们证明TQ可以抑制Wnt /β-catenin信号通路的激活并抑制β-catenin靶基因的表达,例如MYC,Axin-2,MMP7,CyclinD1和MET,它们在EMT和癌症中起关键作用进展。此外,我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。我们证明TQ可以抑制异种移植物的生长并限制肺中肿瘤转移灶的形成。综上所述,我们的发现首次证实了TQ在膀胱癌细胞中的抗转移作用,也为TQ作为一种治疗转移性膀胱癌的新疗法提供了新的证据。
