Available in PDF, EPUB and Kindle. Book excerpt: Increased expression of hepatocyte growth factor (HGF) and its receptor Met has been identified as a possible independent indicator of recurrence in breast cancer patients. Dr. Elliott's laboratory has previously shown increased expression of EGE and Met in regions of invasive human breast cancer. In addition, we have found that breast carcinoma cell lines frequently express EGE and Met, whereas most nonmalignant epithelial cell lines express Met but not HGF. Together these results suggest that establishment of an autocrine EGE loop in carcinoma cells, and the change in the regulation of HGF expression is an important indicator of breast cancer progression. I have shown that in one breast carcinoma cell line MCFlOAl T3B expressed additional forms of HGF. This may represent one mechanism by which breast cancer cells regulate the pericellular level of HGF. I have identified 2 Stat3 binding sites on the HGF promoter, which are required for responsiveness of HGF transcription to the level of c-Src kinase activity. Changes in c-Src kinase activity affect Stat3 activity through its tyrosine phosphorylation and DNA binding affinity. Ras activity can also regulate HGF transcription in breast carcinoma cells, and preliminary evidence suggested phosphatidylinositol 3-kinase is a downstream target of this pathway.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most exciting areas of cancer research now is the development of agents which can target signal transduction pathways that are activated inappropriately in malignant cells. The understanding of the molecular abnormalities which distinguish malignant cells from their normal counterparts has grown tremendously. This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."
Download or read book Role of Hepatocyte Growth Factor Autocrine Loop in Growth and Metastasis of Breast Cancer written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent evidence has shown that hepatocyte growth factor (HGF) is upregulated in human breast cancer, and that this high level of expression is a reliable indicator of recurrence and of poor overall survival of breast cancer patients. We have recently demonstrated co-expression of HGF and HGF receptor (Met) mRNA in invasive human breast carcinomas, as well as in regions of benign hyperplasia. In contrast, most nonmalignant epithelia express Met, but not HGF. These observations suggest that aberrant expression of HGF and subsequent establishment of an autocrine HGF loop could lead to abnormal growth, tumorigenesis and metastasis. The objectives of this grant are: (a) to assess expression of HGF and Met in nonmalignant and malignant breast epithelia, (b) to examine the transcriptional and post-transcriptional mechanisms of regulation of HGF mRNA and protein, and (c) to determine if upregulating, or downregulating HGF or Met expression affects the transformed and tumorigenic phenotypes of mammary carcinoma cells in vitro and in vivo.
Download or read book Regulation of Signal Transduction in Human Cell Research written by Nariyoshi Shinomiya and published by Springer. This book was released on 2018-02-15 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the relationship between the regulation of signal transduction and disease mechanisms, and discusses how the dysregulation of intracellular signals cause diseases, cell death, carcinogenesis, and other disorders. Growth, survival, transformation, and metabolic activities at the cellular level are regulated by various intracellular signal transduction pathways. Sources that stimulate intracellular signals include intracellular stresses and signal regulators/modulators, as well as extracellular growth factors. Recent studies on signal transduction analysis using animal and human cell lines have revealed how the intracellular signals are regulated and why their dysregulation leads to pathological states such as tumorigenesis, metabolic diseases, cell death, and so on. This book highlights several important key molecules and intracellular signaling pathways such as microRNA, the TGF-beta signaling pathway, the Wnt signaling pathway and MET signaling pathway as topical and highly relevant issues in human cell research related to signal transduction. In addition to assessing the pathogenic role of these signaling pathways, it focuses on the molecular design of small molecule regulators/inhibitors of said pathways, one of the most important approaches in this area. This book offers a valuable guide, helping not only research scientists but also clinicians to understand how the dysregulation of intracellular signals leads to diseases.
Download or read book Heparanase written by Israel Vlodavsky and published by Springer Nature. This book was released on 2020-04-09 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by internationally recognized leaders in Heparanase biology, the book’s eight chapters offer an opportunity for scientists, clinicians and advanced students in cell biology, tumor biology and oncology to obtain a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications. Proteases and their involvement in cancer progression have been well addressed and documented; however, the emerging premise presented within this book is that Heparanase is a master regulator of aggressive cancer phenotypes and crosstalk with the tumor microenvironment. This endoglycosidase contributes to tumor-mediated remodeling of the extracellular matrix and cell surfaces, augmenting the bioavailability of pro-tumorigenic and pro-inflammatory growth factors and cytokines that are bound to Heparan sulfate. Compelling evidence ties Heparanase with all steps of tumor progression including tumor initiation, growth, angiogenesis, metastasis, and chemoresistance, supporting the notion that Heparanase is an important contributor to the poor outcome of cancer patients and a validated target for therapy. Unlike Heparanase, heparanase-2, a close homolog of Heparanase, lacks enzymatic activity, inhibits Heparanase, and regulates selected genes that promote normal differentiation and tumor suppression. Written by internationally recognized leaders in Heparanase biology, this volume presents a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications to scientists, clinicians and advanced students in cell biology, tumor biology and oncology.

Download or read book Polyploidization and Cancer written by Randy Y.C. Poon and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Limiting genome replication to once per cell cycle is vital for maintaining genome stability. Although polyploidization is of physiologically importance for several specialized cell types, inappropriate polyploidization is believed to promote aneuploidy and transformation. A growing body of evidence indicates that the surveillance mechanisms that prevent polyploidization are frequently perturbed in cancers. Progress in the past several years has unraveled some of the underlying principles that maintain genome stability. This book brings together leaders of the field to overview subjects relating to polyploidization and cancer.
