The yeast two-hybrid method (or interaction trap) is a powerful technique for detecting protein interactions. The procedure is performed using transcriptional activation of a dual reporter system in yeast to identify interactions between a protein of interest (the bait protein) and the candidate proteins for interaction. The method can be used to screen a(More)
PURPOSE ERBB3 is overexpressed in a broad spectrum of human cancers, and its aberrant activation is associated with tumor pathogenesis and therapeutic resistance to various anticancer agents. Neuregulin 1 (NRG1) is the predominant ligand for ERBB3 and can promote the heterodimerization of ERBB3 with other ERBB family members, resulting in activation of(More)
Using the yeast two-hybrid system we have identified novel potential Cdk4 interacting proteins. Here we described the interaction of Cdk4 with a human homologue of the yeast Drosophila CDC37 gene products. Cdc37 protein specifically interacts with Cdk4 and Cdk6, but not with Cdc2, Cdk2, Cdk3, Cdk5 and any of a number of cyclins tested. Cdc37 is not an(More)
Dysregulated fibroblast growth factor (FGF) signaling has been implicated in the pathogenesis of human cancers. Aberrant activation of FGF receptor 2 (FGFR2) signaling, through overexpression of FGFR2 and/or its ligands, mutations, and receptor amplification, has been found in a variety of human tumors. We generated monoclonal antibodies against the(More)
Cell-based drug screenings indicate that tumors displaying c-MET gene amplification are "addicted" to MET signaling and therefore are very sensitive to MET-targeted agents. However, these screenings were conducted in the absence of the MET ligand, hepatocyte growth factor (HGF), which is abundant in the tumor microenvironment. Sensitivity of six(More)
We describe the construction and characterization of a series of novel cyclin-dependent kinase inhibitors with increased antiproliferative activity for use in the genetic treatment of hyperproliferative cell disorders, such as angioplasty-induced restenosis. These inhibitors were generated through the fusion of truncated versions of the p27 gene to the(More)
Increased levels of growth differentiation factor-15 (GDF15) are associated with cachexia, cardiovascular disease and all-cause mortality. The role of GDF15 in chronic obstructive pulmonary disease (COPD) is unknown.The study included 413 patients with COPD from the Bergen COPD Cohort Study. All patients had a forced expiratory volume in 1 s (FEV1) <80%(More)
Growth differentiating factor-15 (GDF-15), also known as macrophage inhibiting factor-1, is a member of the transforming growth factor-β superfamily, which has been implicated in cancer-associated weight loss. The present study investigated the association between cancer-associated weight loss and plasma GDF-15 concentration, as well as other biomarkers, in(More)

Inhibition of proliferative neointima formed by vascular smooth muscle cells is a potential target in preventing angioplasty-induced restenosis. We have created a potent antiproliferative by fusing the active regions of the p27 and p16 cell cycle inhibitors. Intravascular delivery of a replication-deficient adenoviral vector (AV) encoding this p27-p16(More)
