Rho GTPases信号在人乳腺肿瘤中改变,Rho GTPases的表达和活化升高与肿瘤进展、转移和不良预后相关。在这里,我们审查的证据表明,Rho信号作为一个关键的调节细胞周期,有丝分裂,细胞凋亡,并在乳腺癌的生长和发展过程中的入侵,并讨论这些多效性行动是否增强或限制该网络的靶向。我们提出,根据乳腺癌的阶段和亚型,靶向Rho信号传导可能具有化学预防、抗肿瘤和抗转移的功效。了解Rho信号传导在乳腺癌的特定阶段和亚型中如何受到干扰,以及它在肿瘤形成和进展的随机过程中在复杂的体内环境中如何发挥作用是必要的,以便有效地靶向乳腺癌治疗的信号传导网络。
Rho GTPase signaling is altered in human breast tumors, and elevated expression and activation of Rho GTPases correlates with tumor progression, metastasis, and poor prognosis. Here we review the evidence that Rho signaling functions as a key regulator of cell cycle, mitosis, apoptosis, and invasion during breast cancer growth and progression and discuss whether these pleiotropic actions enhance or limit the targetability of this network. We propose that depending on the stage and subtype of breast cancer, targeting Rho signaling may have chemopreventative, anti-tumor, and anti-metastatic efficacy. An understanding of how Rho signaling is perturbed in specific stages and subtypes of breast cancer and how it functions in the context of the complex in vivo environment during the stochastic process of tumor formation and progression are necessary in order to effectively target this signaling network for breast cancer treatment.
