The transforming growth factor-β (TGF-β) signaling pathway plays an important role in cancer cell proliferation, growth, metastasis, and apoptosis. It has been shown that TGF-β acts as a tumor suppressor in the early stages of the disease, and as a tumor promoter in its late stages. Mutations in the TGF-β signaling components, the TGF-β receptors and cytoplasmic signaling transducers, are frequently observed in colorectal carcinomas. Exploiting specific TGF-β receptor agonist and antagonist with antitumor properties may be a way of controlling cancer progression. This review summarizes the regulatory role of TGF-β signaling in the pathogenesis of colorectal cancer. 相似文献

Hepatocellular carcinoma (HCC) is one of the common malignant human tumors with high morbidity worldwide. Aberrant activation of the oncogenic phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling is related to clinicopathological features of HCC. Emerging data revealed that microRNAs (miRNAs) have prominent implications for regulating cellular proliferation, differentiation, apoptosis, and metabolism through targeting the PI3K/AKT/mTOR signaling axis. The recognition of the crucial role of miRNAs in hepatocarcinogenesis represents a promising area to identify novel anticancer therapeutics for HCC. The present study summarizes the major findings about the regulatory role of miRNAs in the PI3K/AKT/mTOR pathway in the pathogenesis of HCC. 相似文献

The aim of this study was to evaluate the effect of hypertension and its reverse on serum nitric oxide (NO) concentration and endothelial permeability in two-kidney one-clip (2K1C) hypertensive rats. 28 male Wistar rats were divided into four groups: 1) 2K1C for 12 weeks; 2) sham-clipped for 12 weeks; 3) 2K1C for 12 weeks and unclipped for 12 weeks; 4) sham-clipped for 12 weeks and unclipped for 12 weeks. Blood samples were taken before experiment, 12th week and 24th week (in groups 3 and 4). Coronary vascular and aortic endothelial permeability were determined by extravasation of Evans blue dye method. Serum NO level was significantly lower in hypertensive group compare with sham group (4.21 ± 1.28 vs. 9.47 ± 1.34 μmol/l, respectively). Reversal of hypertension did not improve serum NO concentration in 2K1C group (4.21 ± 1.28 vs. 4.32 ± 1.34 μmol/l). Coronary vascular and aortic endothelial permeability were not different between hypertensive and normotensive groups and reversal of hypertension did not alter endothelial permeability. Lower serum NO concentration in 2K1C hypertensive rats even after reversal of hypertension suggested that in addition to NO, other mechanisms could be involved in surgical reversal of hypertension. Hypertension and its reverse did not change endothelial permeability at least in this model of hypertension. 相似文献

To determine the prevalence of G6PD deficiency and a Mediterranean mutation among males in southeastern Iran, we studied 1,097 Sistani and Balouch schoolboys. A questionnaire was used to collect demographic data and a history of malaria infection; blood samples were evaluated for G6PD deficiency and the G6PD Mediterranean mutation. Of the 1,097 boys screened, 175 were G6PD deficient (5.8 % of the Sistani boys and 19.3 % of the Balouch boys). The malaria survey indicated that among Balouch subjects, malaria infection was about 14 times that of Sistani subjects. Molecular characterization of G6PD-deficient samples revealed a general frequency of 85.1 % for the Mediterranean variant among all subjects (75 % among Sistani and 86.2 % among Balouch cases). The high prevalence of G6PD deficiency among Balouch populations confirms the hypothesis that the distribution of G6PD deficiency is concordant with the geographic distribution of malaria. 相似文献
