Exp Mol Med:白藜芦醇可通过抑制RhoA/Lats1/YAP信号轴抑制乳腺癌的进展

2018-02-07 MedSci MedSci原创

Hippo/YAP信通路参与了各种癌症的肿瘤发生和进展。通过抑制多个信号级联,白藜芦醇具有强的抗肿瘤和抗转移活性。 在本研究中,我们证明白藜芦醇可降低YAP靶基因的表达。此外,我们的研究结果显示,白藜芦醇通过激活Lats1并随后使YAP失活而减弱乳腺癌细胞的侵袭。尤其是,我们还发现白藜芦醇使RhoA失活,导致Lats1的激活,并诱导YAP磷酸化。此外,与单一处理相比,白藜芦醇与其他灭活Rh

Hippo/YAP信通路参与了各种癌症的肿瘤发生和进展。通过抑制多个信号级联,白藜芦醇具有强的抗肿瘤和抗转移活性。

在本研究中,我们证明白藜芦醇可降低YAP靶基因的表达。此外,我们的研究结果显示,白藜芦醇通过激活Lats1并随后使YAP失活而减弱乳腺癌细胞的侵袭。尤其是,我们还发现白藜芦醇使RhoA失活,导致Lats1的激活,并诱导YAP磷酸化。此外,与单一处理相比,白藜芦醇与其他灭活RhoA或YAP的药剂组合可更明显的抑制乳腺癌细胞的侵袭。

总的来说,这些研究结果表明,白藜芦醇可通过抑制RhoA/Lats1/YAP信号轴并随后抑制乳腺癌细胞侵袭。
