Novel variation at chr11p13 associated with cystic fibrosis lung disease severity.

Published genome-wide association studies (GWASs) identified an intergenic region with regulatory features on chr11p13 associated with cystic fibrosis (CF) lung disease severity. Targeted resequencing in n=377, followed by imputation to n=6,365 CF subjects, was used to identify unrecognized genetic variants (including indels and microsatellite repeats) associated with phenotype. Highly significant associations were in strong linkage disequilibrium and were seen only in Phe508del homozygous CF subjects, indicating a CFTR genotype-specific mechanism.

Inhibitory effects of docetaxel on expression of VEGF, bFGF and MMPs of LS174T cell.

AIM: To study the effects of non-cytotoxic concentrations of docetaxel on some important angiogenic factors of LS174T Cells. METHODS: The non-cytotoxic concentration of docetaxel and the activity of gelatinase were determined with MTT and gelatin zymography respectively, the expression of VEGF(vascular endothelial growth factor), bFGF (basic fibroblast growth factor), MMP (matrix metalloproteinase) 2 and MMP 9 was investigated with RT-PCR and Western blot. RESULTS: The maximum non-cytotoxic concentration of docetaxel on LS174T Cells was 1.0 ng/ml. Compared with the solvent control group, 0.1, 0.5, 1.0 ng/ml of docetaxel could downregulate the expression of VEGF, bFGF, MMP 2 and MMP 9 and suppress the activity of gelatinase. CONCLUSION: Our study suggests that the non-cytotoxic concentrations of docetaxel have strong antiangiogenic activity on LS174T Cells, which suggests docetaxel may be a promising antiangiogenic agent.
