Hepatoma-derived growth factor (HDGF) is closely related to aggressive tumor behavior and could be a broader biomarker for cancer prognosis and diagnosis. The goal of this study is to develop a sandwich ELISA system to test if HDGF can be detected in serum samples. We produced an anti-HDGF monoclonal antibody designated 2F12 using recombinant human HDGF(More)
In situ hybridization (ISH) is an extremely useful tool for localizing gene expression and changes in expression to specific cell populations in tissue samples across numerous research fields. Typically, a research group will put forth significant effort to design, generate, validate and then utilize in situ probes in thin or ultrathin paraffin embedded(More)
We hypothesized that the study of gene expression at 1, 2, 4, 6 and 16 weeks in the substantia nigra (SN) after intrastriatal 6-OHDA in the Sprague-Dawley rat (rattus norvegicus) would identify cellular responses during the degenerative process that could be axoprotective. Specifically, we hypothesized that genes expressed within the SN that followed a(More)
The inappropriate expression of the c-MET cell surface receptor in many human solid tumors necessitates the development of companion diagnostics to identify those patients who could benefit from c-MET targeted therapies. Tumor tissues are formalin fixed and paraffin embedded (FFPE) for histopathologic evaluation, making the development of an antibody(More)
PURPOSE Aberrant c-Met expression has been implicated in most types of human cancer. We are developing Met-directed imaging and therapeutic agents. EXPERIMENTAL DESIGN To seek peptides that bind specifically to receptor Met, the Met-expressing cell lines S114 and SK-LMS-1 were used for biopanning with a random peptide phage display library. Competition(More)
Inappropriate expression of the receptor tyrosine kinase Met and its ligand hepatocyte growth factor (HGF)/scatter factor (SF) is usually associated with an aggressive solid tumor phenotype (angiogenesis, invasiveness, and metastasis) and poor clinical prognosis. We report here the design and construction of a large, human naïve antigen-binding fragment(More)
The aims of this study were to generate a human Fab fragment against EGFR; conjugate it to paclitaxel (Taxol) as an immuno-chemotherapy agent; and investigate its in vitro anti-tumor efficacy on A431 epidermoid carcinoma cells. A431 cells (EGFR-positive), NIH 3T3 cells (EGFR-negative), and purified EGFR were used for subtractive panning on a human naïve Fab(More)
Phosphatidylethanolamine binding protein 1 (PEBP1), also known as Raf kinase inhibitor protein (RKIP), has been considered as a suppressor of metastasis and a prognostic marker in prostate cancer, breast cancer, gastrointestinal stromal tumors, melanoma, and epithelial ovarian cancer. In this report, recombinant PEBP1 was successfully expressed in an(More)
A successful therapeutic strategy, specifically tailored to the molecular constitution of an individual and their disease, is an ambitious objective of modern medicine. In this report, we highlight a feasibility study in canine osteosarcoma focused on refining the infrastructure and processes required for prospective clinical trials using a series of gene(More)
Glycogen synthase kinase 3 (GSK3) β and α are serine/threonine kinases involved in many biological processes. A primary mechanism of GSK3 activity regulation is phosphorylation of N-terminal serine (S) residues (S9 in GSK3β, S21 in GSK3α). Phosphorylation is inhibitory to GSK3 kinase activity because the phosphorylated N-terminus acts as a competitive(More)
