          Abstract

          Pancreatic cancer is the 4th leading cause of cancer-related death in the United States. The number of diagnoses per year equals the number of deaths per year, making it the deadliest of all malignancies. Modern advances and breakthroughs in molecular oncology have allowed researchers to gain a better understanding of the mechanisms responsible for the pathogenesis of this disease. The transforming growth factor-β (TGF-β) pathway is one of the signaling systems that has been identified as a major contributor. TGF-β plays a paradoxical role as both a tumor suppressor and a tumor promoter in pancreatic cancer. The purpose of this review is to provide the practicing clinician a thorough review of this molecule and its associated signaling partners in the context of its duplicitous role and behavior in patients with pancreatic cancer.

          TGF-beta signal transduction.

          The transforming growth factor beta (TGF-beta) family of growth factors control the development and homeostasis of most tissues in metazoan organisms. Work over the past few years has led to the elucidation of a TGF-beta signal transduction network. This network involves receptor serine/threonine kinases at the cell surface and their substrates, the SMAD proteins, which move into the nucleus, where they activate target gene transcription in association with DNA-binding partners. Distinct repertoires of receptors, SMAD proteins, and DNA-binding partners seemingly underlie, in a cell-specific manner, the multifunctional nature of TGF-beta and related factors. Mutations in these pathways are the cause of various forms of human cancer and developmental disorders.

            Targeted disruption of the mouse transforming growth factor-beta 1 gene results in multifocal inflammatory disease.

            Transforming growth factor-beta 1 (TGF-beta 1) is a multifunctional growth factor that has profound regulatory effects on many developmental and physiological processes. Disruption of the TGF-beta 1 gene by homologous recombination in murine embryonic stem cells enables mice to be generated that carry the disrupted allele. Animals homozygous for the mutated TGF-beta 1 allele show no gross developmental abnormalities, but about 20 days after birth they succumb to a wasting syndrome accompanied by a multifocal, mixed inflammatory cell response and tissue necrosis, leading to organ failure and death. TGF-beta 1-deficient mice may be valuable models for human immune and inflammatory disorders, including autoimmune diseases, transplant rejection and graft versus host reactions.
