摘要
Background Patients with Birt-Hogg-Dube ( BHD) syndrome harbor germline mutations in the BHD tumor suppressor gene that are associated with an increased risk for kidney cancer. BHD encodes folliculin, a protein that may interact with the energy- and nutrient-sensing 5'-AMP-activated protein kinase-mammalian target of rapamycin (AMPK-mTOR) signaling pathways. Methods We used recombineering methods to generate mice with a conditional BHD allele and introduced the cadherin 16 ( KSP)-Cre transgene to target BHD inactivation to the kidney. Kidney cell proliferation was measured by BrdU incorporation and phospho-histone H3 staining. Kidney weight data were analyzed with Wilcoxon's rank-sum, Student's t, and Welch's t tests. Hematoxylin and eosin staining and immunoblot analysis and immunohistochemistry of cell cycle and signaling proteins were performed on mouse kidney cells and tissues. BHD knockout mice and kidney cells isolated from BHD knockout and control mice were treated with the mTOR inhibitor rapamycin. Mouse survival was evaluated by Kaplan-Meier analyses. All statistical tests were two-sided. Results BHD knockout mice developed enlarged polycystic kidneys and died from renal failure by 3 weeks of age. Targeted BHD knockout led to the activation of Raf-extracellular signal-regulated protein kinase ( Erk)1/ 2 and Akt-mTOR pathways in the kidneys and increased expression of cell cycle proteins and cell proliferation. Rapamycin-treated BHD knockout mice had smaller kidneys than buffer-treated BHD knockout mice had ( n = 4 - 6 mice per group, relative kidney/ body weight ratios, mean = 4.64% vs 12.2%, difference = 7.6%, 95% confidence interval = 5.2% to 10.0%; P <.001) and longer median survival time ( n = 4 - 5 mice per group, 41.5 vs 23 days; P =.0065). Conclusions Homozygous loss of BHD may initiate renal tumorigenesis in the mouse. The conditional BHD knockout mouse may be a useful research model for dissecting multistep kidney carcinogenesis, and rapamycin may be considered as a potential treatment for Birt-Hogg-Dube syndrome.
