1Prognostic significance of vascular endothelial growth factor polymorphisms in colorectal cancer patients显示文摘AIM To investigate the associations of the genetic polymor-phisms of vascular endothelial growth factor A(VEGF-A)-1498C>T and-634G>C, with the survival of patients with colorectal cancer(CRC). METHODS A prospective cohort consisting of 131 Brazilians patients consecutively operated on with a curative intention as a result of sporadic colorectal carcinoma was studied. DNA was extracted from peripheral blood and its amplification and allelic discrimination for each genetic polymorphism was performed using the technique of polymerase chain reaction(PCR) in real-time. The real-time PCR technique was used to identify the VEGF-A-1498C>T(rs833031) and-634G>C(rs2010963) polymorphisms. Genotyping was validated for VEGF-A-1498C>T polymorphism in 129 patients and for VEGF-A-634G>C polymorphism in 118 patients. The analysis of association between categorical variables was performed using logistic regression, survival by Kaplan-Meier method and multivariate analysis by the Cox regression method. RESULTS In the univariate analysis there was a significant association(OR = 0.32; P = 0.048) between genotype CC of the VEGF-A-1498C>T polymorphism and the presence of CRC liver metastasis. There was no association between VEGF-A-1498C>T polymorphism and VEGF-A-634G>C polymorphism with further clinical or anatomopathologic variables. The genotype CC of the VEGF-A-1498C>T polymorphism was significantly correlated with the 5-year survival(P = 0.032), but not significant difference(P = 0.27) was obtained with the VEGF-A-634G>C polymorphism with the 5-year survival in the univariate analysis. The genotype CT(HR = 2.79) and CC(HR = 4.67) of the polymorphism VEGF-A-1498C>T and the genotype CC(HR = 3.76) of the polymorphism VEGF-A-634C>G acted as an independent prognostic factor for the risk of death in CRC patients. CONCLUSION The CT and CC genotypes of the VEGF-A-1498C>T and the CC genotype of the VEGF-A-634C>G polymorphisms are prognostic factors of survival in Brazilians patients with sporadic colorectal carcinoma.Gilmar Ferreira do Espírito Santo Bianca Borsatto Galera Elisabeth Carmen Duarte Elisabeth Suchi Chen Lenuce Azis Amilcar Sabino Damazo Gabriela Tognini Saba Flávia de Sousa Gehrke Ismael Dale Cotrim Guerreiro da Silva Jaques Waisberg 2017World Journal of Gastrointestinal Oncology2017,9,2:4
2Infrared fluorescence imaging of infarcted hearts with A@S nanodots显示文摘Ag2S nano dots have already bee n dem onstrated as promisi ng n ear-i nfrared (NIR-II, 1.0-1.45 pm) emitting nan oprobes with low toxicity, high penetration and high resolution for in vivo imaging of, for example, tumors and vasculature. In this work, we have systematically investigated the pote ntial applicati on of function alized Ag2S nano dots for accurate imaging of damaged myocardium tissues after a myocardial in farction in duced by either partial or global ischemia. Ag2S nano dots surface-function alized with the an giote nsin II peptide (ATI I) have show n over 10-fold enhanced binding efficiency to damaged tissues than non-specifically (PEG) functionalized Ag2S nanodots due to their interaction with the upregulated angiotensin II receptor type I (AT1R). It is demonstrated how the NIR-II images generated by ATII-functionalized Ag2S nanodots contain valuable information about the location and extension of damaged tissue in the myocardium allowing for a proper identification of the occluded artery as well as an in direct evaluati on of the damage level. The pote ntial applicati on of Ag2S nano dots in the n ear future for in vivo imaging of myocardial infarction was also corroborated by performing proof of concept whole body imaging experiments.Dirk H.
