肝细胞癌 (HCC) 是全球第三大癌症死亡原因,大多数 HCC 患者的治疗选择有限。粘着斑激酶 (FAK) 在许多 HCC 标本中过度表达,为 HCC 治疗提供了潜在靶点。然而,FAK 在肝癌发生中的作用仍不清楚。确定 FAK 表达是否在 HCC 发展中发挥作用对于确定它是否是可行的治疗靶点至关重要。在这项研究中,我们培育了肝细胞特异性缺失 Fak 的小鼠,并研究了 Fak 在致癌(c-MET/β-连环蛋白,MET/CAT)驱动的 HCC 模型中的作用。我们发现肝细胞中Fak的缺失并不影响形态、增殖或凋亡。然而,Fak 缺陷显着抑制 MET/CAT 诱导的肿瘤发展,并延长 MET/CAT 诱导的 HCC 动物的生存期。在小鼠肝脏和 HCC 细胞系中,Fak 被 MET 激活,从而诱导 Akt/Erk 激活并上调 Cyclin D1 和肿瘤细胞增殖。 CAT 增强 MET 刺激的 FAK 激活,并以 FAK 激酶依赖性方式协同诱导 AKT/ERK-Cyclin D1 信号通路的激活。此外,FAK 是 CAT 诱导的 Cyclin D1 以激酶独立方式表达所必需的。 Fak 是 c-Met/β-连环蛋白驱动的肝癌发生所必需的。抑制 FAK 提供了治疗 HCC 的潜在策略。
Hepatocellular carcinoma (HCC) is the third most common cause of cancer death worldwide and most patients with HCC have limited treatment options. Focal Adhesion Kinase (FAK) is overexpressed in many HCC specimens, offering a potential target for HCC treatment. However, the role of FAK in hepatocarcinogenesis remains elusive. Establishing whether FAK expression plays a role in HCC development is necessary to determine whether it is a viable therapeutic target. In this study, we generated mice with hepatocyte-specific deletion of Fak and investigated the role of Fak in an oncogenic (c-MET/β-catenin, MET/CAT)-driven HCC model. We found that deletion of Fak in hepatocytes did not affect morphology, proliferation or apoptosis. However, Fak deficiency significantly repressed MET/CAT-induced tumor development and prolonged survival of animals with MET/CAT-induced HCC. In mouse livers and HCC cell lines, Fak was activated by MET, which induced the activation of Akt/Erk and up-regulated Cyclin D1 and tumor cell proliferation. CAT enhanced MET-stimulated FAK activation and synergistically induced the activation of the AKT/ERK-Cyclin D1 signaling pathway in a FAK kinase-dependent manner. In addition, FAK was required for CAT-induced Cyclin D1 expression in a kinase-independent fashion. Fak is required for c-Met/β-catenin-driven hepatocarcinogenesis. Inhibition of FAK provides a potential strategy to treat HCC.
