Several specific modifications, both proteolytic and chemical, have been performed on RNase A. The ability of each of these RNase A derivatives to bind the human placental RNase inhibitor has been determined in competition binding assays. The interaction depends upon the native conformation of the enzyme. Loss of active site residues His-12 and His-119, along with auxiliary residues Lys-7, Phe-...
We report here the complete genome sequence of Candida tropicalis no. 121. C. tropicalis no. 121 is a high-RNA-producing strain obtained by mutagenesis in our laboratory. The complete genome sequence was determined using the Illumina HiSeq 2000 and contains 6,415 genes. The genome size of C. tropicalis no. 121 is >15.3 Mb.
BACKGROUND Administration of angiogenic factors stimulates neovascularization in ischemic tissues. However, there is no evidence that angiogenesis can be induced in normoperfused skeletal muscles. We tested the hypothesis that adenovirus-mediated intramuscular (IM) gene transfer of the 121-amino-acid form of vascular endothelial growth factor (AdCMV.VEGF(121)) could stimulate neovascularization...
PURPOSE Activation or overexpression of HER-2/neu is associated with up-regulation of vascular endothelial growth factor (VEGF) in human breast cancer cells in vitro. Preclinical experiments indicate that increased expression of VEGF may in part mediate the biologically aggressive phenotype of HER-2/neu-overexpressing human breast cancer. It was the purpose of this study to: (a). evaluate the a...
Midkine (MDK) is a member of a new family of neurotrophic factors considered as rate-limiting growth and angiogenic factors implicated in the onset, invasion, and metastatic process of neuronal tumors, including neuroblastoma. We showed that all neuroblastoma cell lines highly expressed MDK, indicating that it is a critical player in tumor development, which may henceforth represent an attracti...
Vascular endothelial growth factor (VEGF) occurs in at least five different isoforms because of alternative splicing of the gene. To investigate the roles of different VEGF isoforms in tumor blood vessel formation and tumorigenicity, the three major isoforms (VEGF(121), VEGF(165), and VEGF(189)) were overexpressed in an early-stage human melanoma cell line (WM1341B), which is VEGF-negative and ...
COPD is characterized by persistent airflow limitation, neutrophilia and oxidative stress from endogenous and exogenous insults. Current COPD therapy involving anticholinergics, β2-adrenoceptor agonists and/or corticosteroids, do not specifically target oxidative stress, nor do they reduce chronic pulmonary inflammation and disease progression in all patients. Here, we explore the effects of Su...
