This book was released on 2011 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metastasis is the leading cause of death in patients with cancer, and the extracellular matrix is critical to cancer dissemination. The adhesion receptor, CD44, mediates cellular communication with the extracellular matrix by binding to the glycosaminoglycan, hyaluronan (HA). CD44 and HA play critical roles in cancer progression and development. HA is deposited in extracellular and pericellular matrices where it directs intracellular signaling through interactions with cell-surface CD44. CD44-HA interactions, in turn, direct signaling that is relevant to cancer progression. Importantly, these molecules can both promote and inhibit the oncogenic cascade, although the mechanism by which they promote dual and contrasting functions is unknown. Here we show that HA can both activate and suppress EGFR, a critical regulator of oncogenic signaling, in a context-dependent fashion. Using a 3D collagen system in which HA is either polymerized in collagen matrix or provided soluble in the media (sHA) we report that collagen-embedded HA (eHA) inhibits EGFR activation, filopodia formation, and cell spreading on a collagen matrix. Additionally, we show that CD44 is subject to cell-type changes during cancer progression. We have found that CD44 is expressed in the myoepithelium of the developing mammary gland and regulates the normal function of this cell type. The myoepithelial function of CD44 is also relevant to its role in cancer progression as CD44 is expressed in the basal cells of early-stage breast and prostate cancer but undergoes a basal to luminal epithelial switch with increasing tumorigenicity and is strongly expressed by tumor epithelium. These findings demonstrate a novel role for eHA as a protective molecule when encountered in the collagen matrix during cancer progression and highlight the importance of understanding cell-type specific contributions during cancer progression. Taken together, the findings reported in this dissertation point to a mechanism by which CD44 and HA can function in tumor suppression and promotion, depending on cell-type specific expression and modulation of the extracellular matrix.

Download or read book Extracellular Matrix Degradation written by William C. Parks and published by Springer Science & Business Media. This book was released on 2011-04-07 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regulated turnover of extracellular matrix (ECM) is an important component of tissue homeostasis. In recent years, the enzymes that participate in, and control ECM turnover have been the focus of research that touches on development, tissue remodeling, inflammation and disease. This volume in the Biology of Extracellular Matrix series provides a review of the known classes of proteases that degrade ECM both outside and inside the cell. The specific EMC proteases that are discussed include cathepsins, bacterial collagenases, matrix metalloproteinases, meprins, serine proteases, and elastases. The volume also discusses the domains responsible for specific biochemical characteristics of the proteases and the physical interactions that occur when the protease interacts with substrate. The topics covered in this volume provide an important context for understanding the role that matrix-degrading proteases play in normal tissue remodeling and in diseases such as cancer and lung disease.

Download or read book Epithelial Mesenchymal Plasticity in Cancer Metastasis written by Mohit Kumar Jolly and published by MDPI. This book was released on 2020-12-29 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have highlighted that epithelial-mesenchymal transition (EMT) is not only about cell migration and invasion, but it can also govern many other important elements such as immunosuppression, metabolic reprogramming, senescence-associated secretory phenotype (SASP), stem cell properties, therapy resistance, and tumor microenvironment interactions. With the on-going debate about the requirement of EMT for cancer metastasis, an emerging focus on intermediate states of EMT and its reverse process mesenchymal-epithelial transition (MET) offer new ideas for metastatic requirements and the dynamics of EMT/MET during the entire metastatic cascade. Therefore, we would like to initiate discussions on viewing EMT and its downstream signaling networks as a fulcrum of cellular plasticity, and a facilitator of the adaptive responses of cancer cells to distant organ microenvironments and various therapeutic assaults. We hereby invite scientists who have prominently contributed to this field, and whose valuable insights have led to the appreciation of epithelial-mesenchymal plasticity as a more comprehensive mediator of the adaptive response of cancer cells, with huge implications in metastasis, drug resistance, tumor relapse, and patient survival.

Download or read book Interaction between Hyaluronic Acid and Its Receptors CD44 RHAMM Regulates the Activity of Inflammation and Cancer written by David Naor and published by Frontiers Media SA. This book was released on 2016-07-18 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological outcome of Hyaluronan (also hyaluronic acid, abbreviated HA) interaction with its CD44 or RHAMM receptors recently attracted much attention within the scientific community owing to a Nature article by Tian X et al. (Nature 2013; 499:346-9). The article described a life span exceeding 30 years in naked mole rats, whereas the maximal lifespan of mice, to which the naked mole rat is related, is only 4 years. This observation is accompanied by the finding that the naked mole rat, in contrast to the mouse, does not develop spontaneous tumors during this exceptional longevity. The article provides evidence that interaction of long tissue HA (6000-12,000 kDa) of the naked mole rat with cell surface CD44, in contrast to the interaction of short tissue HA (less than 3000 kDa) with the mouse CD44, makes the difference. More specifically, this communication shows that the interaction of short HA with fibroblasts’ CD44 imposes on them susceptibility for malignant transformation, whereas the corresponding interaction with long HA imposes on the fibroblasts a resistance to malignant transformation. The article does not explain the mechanism that underlines these findings. However, the articles, that will be published in the proposed Research Topic in the Inflammation section of Frontiers in Immunology, can bridge not only this gap, but also may explain why interaction between short HA and cell surface CD44 (or RHAMM, an additional HA receptor) enhances the development of inflammatory and malignant diseases. Furthermore, the articles included in the proposed Frontiers Research Topic will show that cancer cells and inflammatory cells share several properties related to the interaction between short HA and cell surface CD44 and/or RHAMM. These shared properties include: 1. Support of cell migration, which allows tumor metastasis and accumulation of inflammatory cells at the inflammation site; 2. Delivery of intracellular signaling, which leads to cell survival of either cancer cells or inflammatory cells; 3. Delivery of intracellular signaling, which activates cell replication and population expansion of either cancer cells or inflammatory cells; and 4. Binding of growth factors to cell surface CD44 of cancer cells or inflammatory cells (i.e., the growth factors) and their presentation to cells with cognate receptors (endothelial cells, fibroblasts), leading to pro-malignant or pro-inflammatory activities. Going back to the naked mole rat story, we may conclude from the proposed articles of this Frontiers Research Topic that the long HA, which displays anti-malignant effect, interferes with the above described pro-malignant potential of the short HA (perhaps by competing on the same CD44 receptor). Extrapolating this concept to Inflammation, the same mechanism (competition?) may be valid for inflammatory (and autoimmune) activities. If this is the case, long HA may be used for therapy of both malignant and inflammatory diseases. Moreover, targeting the interaction between short HA and CD44 (e.g. by anti-CD44 blocking antibodies) may display also a therapeutic effect on both malignant and inflammatory diseases, an issue that encourages not only fruitful exchange of views, but also practical experimental collaboration.
