The prognosis for individuals that are diagnosed with gastric cancer remains poor due to the high frequency of metastatic disease. In response to tumor-derived secreted factors, the bone marrow generates a suitable microenvironment for the development of metastasis. However, it is largely unknown whether secreted factors in bone marrow associated with metastatic disease of patients with gastric...
To investigate the pathophysiological role of fibroblasts in tissue metabolism, we analysed gelatin-degrading enzymes secreted from skin cells in culture. Using a gelatin-zymography method, matrix metalloproteinase (MMP)-2 was constitutively secreted from fibroblasts, whereas both MMP-2 and MMP-9 were secreted from keratinocytes. MMP-9 expression by fibroblasts was induced by the addition of tr...
As cells progress through the multistep process of neoplastic transformation, they eventually acquire the property of invasive behavior. Although both plasminogen activators (PA) and their inhibitors (PAI) contribute to this process, their regulation in normal and transformed cells remains poorly defined. Because somatic cell hybrids provide useful tools for examining the transformation pathway...
Musculoskeletal malignancy is often accompanied by aberrant bone remodeling, leading to tumor cell invasion into skeletal tissues and causing severe pain. BMPs, FGF-2, RANKL have been identified as promising regulators in physiological remodeling. In this study, we explored the expressional profile of 1361 patients with 22 varieties musculoskeletal tumors. Notably, expression FGF-2 was under de...
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of TNF family, is an interesting ligand which selectively induces apoptosis in tumor cells and, therefore, it has been developed for cancer therapy. This ligand has been produced by various hosts such as E.coli. However, protein expression in E.coli cytoplasm leads to problems such as incorrect folding, reduction in biolo...
Infectious Pancreatic Necrosis Virus (IPNV) is a member of the family Birnaviridae that has been linked to high mortalities in salmonids. Bacterial based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. VP2 is a structural viral protein of IPNV with immunogenicity effects. In this study IPNV was isolated from diseased fry ...
the ability of tnf related apoptosis inducing ligand/apo2 ligand (trail/apo2l) in order to selectively induce apoptosis in tumor cells but not normal cells makes it an attractive target for development of new cancer therapy. although trail/apo2l has been produced in several hosts, e. coli is one of the best expression systems among them due to its safety, simplicity, low cultivation cost, and k...
We explored whether adipocyte culture medium affects the secreted chemokine profile of tumor cells, because adipocytes stimulate progression or metastasis of breast cancer cells, and chemokines secreted from tumor cells are involved in these processes. CCL20 expression was dramatically increased, and an NF-kappaB blocker completely inhibited adipocyte culture medium-induced CCL20 expression in ...
Expression of the membrane-bound version of the human mu chain in transgenic mice results in the allelic exclusion of endogenous mouse Ig heavy chain genes (6). The secreted version of the human Ig transgene has no such effect. F1 hybrid animals that carry transgenes for both secreted and membrane-bound human mu chains produce both forms of the human heavy chain while strongly suppressing endog...
The APP plays a central role in AD, a pathology that first manifests as a memory decline. Understanding the role of APP in normal cognition is fundamental in understanding the progression of AD, and mammalian studies have pointed to a role of secreted APPα in memory. In Drosophila, we recently showed that APPL, the fly APP ortholog, is required for associative memory. In the present study, we a...
