The Collagens: Biochemistry and Pathophysiology


Book Description

This book describes every manner in which collagen is involved in normal anddisease-altered states of the various organs and systems. In the first part of the book the biochemical aspects of collagens are reviewed, including their structure, heterogeneity, syntheses, and degradation. The main part focuses on the involvement of collagen in bone, cartilage, tendon, muscle, heart, vessels, lungs, liver, skin, eye, ear, teeth, periodontal tissues, kidneys and reproductive, hemopoietic,and nervous systems. The influence of radiation and nutrition on collagen, the role of collagen in neoplasms, the hormonal control of its metabolism, immunobiology and the pharmacology of collagen are also described. The most important feature of the book is the comprehensive review of the medical aspects of collagen, from those known in detail to those only hypothesized including hereditary disorders affecting collagen and so-called collagen diseases. Each chapter reviewsknown or possible mechanisms of collagen involvement and changes in indices of collagen which can be measured in clinical practice to monitor these phenomena. The fact that collagen is involved into the pathophysiology of almost all organs and body systems means that physicians in almost all branches of medicine will find this book of great interest.




Biochemistry of Collagens, Laminins and Elastin


Book Description

Biochemistry of Collagens, Laminins, and Elastin: Structure, Function, and Biomarkers provides a comprehensive introduction to collagen and structural proteins. Type I collagen is one of the most abundant molecules in the body, playing essential roles in different tissues, particularly bone and skin. A key aspect of type I collagen is its post-translational modifications which are essential for correct synthesis and structural integrity of collagens, for tissue-specific functionality, as well as for application as biomarkers of different pathologies. This volume summarizes current data on key structural proteins (collagens, laminins and elastin), reviews how these molecules affect pathologies, and describes selected modifications of proteins that result in altered signaling properties of the original extracellular matrix component. Further, it discusses the novel concept that an increasing number of components of the ECM harbor cryptic signaling functions that may be viewed as endocrine functions. Additionally, it highlights how this knowledge can be exploited to modulate fibrotic disease. - Provides a comprehensive introduction to collagen and structural proteins - Provides insight into emerging analytical technologies that can detect biomarkers of extracellular matrix degradation - Includes a chapter dedicated to the biomarkers of structural proteins - Contains insights into the biochemical interactions and changes to structural composition of proteins in disease states




Biochemistry of Collagen


Book Description

Collagen is a fascinating protein not only because of its ubiquitous occurrence in multicellular animals, but also because of its unique chemi cal structure. As the predominant constituent in bone, cartilage, skin, tendon, and tooth, it is not surprising that collagen is of interest to anatomists, biochemists, biomedical engineers, cell biologists, dermatolo gists, dental surgeons, leather chemists, orthopedic surgeons, physiologists, physicians, zoologists, and a host of others. This book was planned to provide an up-to-date comprehensive survey of all aspects of biochemistry of collagen. The recent discovery of genetically distinct collagens with tissue specificity has opened a new era in collagen biochemistry, and Karl Piez discusses this in the opening chapter on primary structure. In the next chapter, Ramachandran and Rama krishnan deal with the molecular structure of collagen, placing special emphasis on the conformational aspects of its polypeptide chains. Follow ing the consideration of primary and secondary structure of collagen, the three-dimensional arrangement of collagen molecules in the fibrils is covered by Miller in Chapter 3. Collagen is generally in the insoluble state in the living organism due to the cross-linking of individual molecules, and Tanzer describes the various aspects of this cross-linkage in Chapter 4. The biosynthesis of collagen is discussed in depth by Prockop and his colleagues.

Progress in Heritable Soft Connective Tissue Diseases


Book Description

This volume is a reference handbook focusing on diseases like Marfan syndrome, Ehlers-Danlos syndrome, Loeys-Dietz syndrome and other heritable soft connective tissue diseases. The book presents detailed information for both basic scientists and for clinicians seeing patients. It is also a stepping stone for new investigations and studies that goes beyond the facts about the composition and biochemistry of the connective tissue and extracellular matrix, as the authors connect individual components to specific aspects of various soft tissue disorders and to the actual or potential treatment of them. Progress in Heritable Soft Connective Tissue Diseases features very prominent physicians and scientists as contributors who bring their most recent discoveries to the benefit of readers. Their expertise will help clinicians with proper diagnosis of sometimes elusive and uncommon heritable diseases of soft connective tissues. This book also offers an update on the pathophysiology of these diseases, including an emphasis on unifying aspects such as connections between embryonic development of the different types of connective tissues and systems, and the role of TGF-beta in development and physiology of soft tissues. This new set of data explains, at least in part, why many of these disorders are interconnected, though the primary pathophysiological events, such as gene mutations, may be different for each disorder.




Collagen


Book Description

Not only does this book provide a comprehensive review of current research advances in collagen structure and mechanics, it also explores this biological macromolecule’s many applications in biomaterials and tissue engineering. Readers gain an understanding of the structure and mechanical behavior of type I collagen and collagen-based tissues in vertebrates across all length scales, from the molecular (nano) to the organ (macro) level.




Cell Biology of Extracellular Matrix


Book Description

In the ten-year interval since the first edition of this volume went to press, our knowledge of extracellular matrix (ECM) function and structure has enor mously increased. Extracellular matrix and cell-matrix interaction are now routine topics in the meetings and annual reviews sponsored by cell biology societies. Research in molecular biology has so advanced the number of known matrix molecules and the topic of gene structure and regulation that we won dered how best to incorporate the new material. For example, we deliberated over the inclusion of chapters on molecular genetics. We decided that with judicious editing we could present the recent findings in molecular biology within the same cell biology framework that was used for the first edition, using three broad headings: what is extracellular matrix, how is it made, and what does it do for cells? Maintaining control over the review of literature on the subject of ECM was not always an easy task, but we felt it was essential to production of a highly readable volume, one compact enough to serve the the student as an introduction and the investigator as a quick update on graduate the important recent discoveries. The first edition of this volume enjoyed con hope the reader finds this edition equally useful. siderable success; we D. Hay Elizabeth vii Contents Introductory Remarks 1 Elizabeth D. Hay PART I.

The Collagen Superfamily and Collagenopathies


Book Description

This book aims at providing insights into the collagen superfamily and the remarkable diversity of collagen function within the extracellular matrix. Additionally, the mechanisms underlying collagen-related diseases such as dystrophic epidermolysis bullosa, osteogenesis imperfecta, as well as collagen-related myopathies and neurological disorders are discussed. Collagens are the most abundant extracellular matrix proteins in organisms. Their primary function is to provide structural support and strength to cells and to maintain biomechanical integrity of tissues. However, collagens can no longer be considered just as structural proteins. They can act as extracellular modulators of signaling events and serve critical regulatory roles in various cell functions during embryonic development and adult homeostasis. Furthermore, collagens are associated with a broad spectrum of heritability-related diseases known as “collagenopathies” that affect a multitude of organs and tissues including sensorial organs. The book is a useful introduction to the field for junior scientists, interested in extracellular matrix research. It is also an interesting read for advanced scientists and clinicians working on collagens and collagenopathies, giving them a broader view of the field beyond their area of specialization.




Ultrastructure of the Connective Tissue Matrix


Book Description

In recent years, the techniques of electron microscopy have developed so widely and rapidly that they now cover the fields of research once the unique ll:panage of sister research techniques such as biochemistry, physiology, immunology, X-ray diffraction, etc. It is now possible to reach molecular and submolecular levels, making this technique indispensable in every type of research. Electron microscopy alone often provides enough information to solve given problems. In the field of the connective tissue matrix, knowledge of the molecular structure of collagen, pro teoglycans and elastin and their interaction has been to a large extent elucidated by electron microscopy. The field over which electron microscopy ranges in the investigation of the connective tissue matrix is so wide that the aim of this volume is to collect the main ultrastructural acquisitions disseminated in various journals and monographs in one book. The intent ofthis volume is to: (a) integrate different and new microscopic methods and review the results of such an integrative approach; (b) present a comprehensive ultrastructural account of selected aspects of the field; (c) point out gaps or controversial topics in our knowledge; (d) outline pertinent future research and expansion of the subject.
