Expression pattern and targeting of HER family members and IGF-IR in pancreatic cancer.
Summary of "Expression pattern and targeting of HER family members and IGF-IR in pancreatic cancer."
Pancreatic cancer is still one of the most aggressive and fatal types of human cancer . Survival rates for patients with pancreatic cancer are extremely poor and one major contributing factor is the lack of specific marker(s) for the early detection of pancreatic cancer. Indeed, the great majority of pancreatic cancer cases are diagnosed at an advanced stage of the disease and these patients often have a poor response to treatment with conventional forms of therapy. In this article, we conduct a comprehensive review of the literature on the expression pattern, prognostic significance and predictive value of EGFR family members, IGF-IR and their ligands in pancreatic cancer. We also discuss recent advances in pancreatic cancer treatments and highlight the remaining challenges as well as future opportunities for more effective targeting of such receptors using a combination of growth factor receptor specific monoclonal antibodies, small molecule tyrosine kinase inhibitors and other therapeutic strategies. Such strategies could ultimately help to overcome the development of drug resistance and improve the overall survival rates for patients with pancreatic cancer.

Medical and Biotech [MESH] Definitions
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Pancreatic Stellate Cells
Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.
The integration of exogenous DNA into the genome of an organism at sites where its expression can be suitably controlled. This integration occurs as a result of homologous recombination.
A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.
Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.
To date, dozens of melanoma-associated antigens (MAGE) have been identified. Based on the differences in tissue-specific gene expression and gene structure, the MAGE family has been divided into two b...
A20 protein plays essential roles in tumorigenesis, but its value for diagnosis of pancreatic cancer remains unclear. Our aim was to determine whether A20 is a potential biomarker for the diagnosis of...
Epithelial ovarian cancer (EOC) represents the most challenging of gynecological malignancies. Defective apoptosis is a major causative factor in the development and progression of cancer. The two imp...
Members of the epidermal growth factor receptor (EGFR) family represent validated targets for anti-cancer therapy and EGFR inhibitors have also shown efficacy in pancreatic carcinoma. We here describe...
We previously identified Hop as over expressed in invasive pancreatic cancer cell lines and malignant tissues of pancreatic cancer patients, suggesting an important role for Hop in the biology of inva...

The purpose of this trial is to investigate the expression of different inflammatory proteins in cancer and normal pancreatic tissue.
The stepwise process of leukocyte extravasation to inflamed tissues depends on the expression of a variety of cytokines and adhesion molecules. Recently much attention has focused on the J...
