Available in PDF, EPUB and Kindle. Book excerpt: Elevated levels in blood serum (≥10[micromoles/litre]) of the amino acid homocysteine is strongly correlated with the incidence of heart failure (HF). We present evidence that the cyclic thioester, homocysteine thiolactone (HTL), a metabolic product of homocysteine, irreversibly modifies proteins that regulate the contractile process in cardiac muscle. Two proteins found in the sarcoplasmic reticulum (SR), the Ca2+ pump (SERCA2), and the ryanodine receptor (RyR2), are responsible for controlling the cytosolic Ca2+ concentration and hence the contractile state of the heart. While both improper Ca2+ handling and elevated homocysteine levels have been considered bio-markers in HF, a direct connection between the two has not previously been made. We show that HTL reacts with lysine residues on RyR2, generating a N[lowercase epsilon]-homocysteine-protein, which results in carbonyl formation and a change in the Ca2+ sensitivity of RyR2. This is a new molecular mechanism linking elevated levels of Homocysteine, improper Ca2+ handling and heart failure. This work was supported by NIH 1 R41 HL105063-01 to J. Abramson and R. Strongin.

Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

This book was released on 2013-06-20 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess of homocysteine, a product of the metabolism of the essential amino acid methionine, is associated with poor health, is linked to heart and brain diseases in general human populations, and accelerates mortality in heart disease patients. Neurological and cardiovascular abnormalities occur in patients with severe genetic hyperhomocysteinemia and lead to premature death due to vascular complications. Although it is considered a non-protein amino acid, studies over the past dozen years have discovered mechanisms by which homocysteine becomes a component of proteins. Homocysteine-containing proteins lose their normal biological function and become auto-immunogenic and pro-thrombotic. In this book, the author, a pioneer and a leading contributor to the field, describes up-to date studies of the biological chemistry of homocysteine-containing proteins, as well as pathological consequences and clinical implications of their formation. This is a comprehensive account of the broad range of basic science and medical implications of homocysteine-containing proteins for health and disease. ​

Available in PDF, EPUB and Kindle. Book excerpt: This book provides the readers with an up-to-date review of the design, structure and function of a representative selection of fibrous proteins in both health and disease. The importance of the α-helical coiled coil, a conformational motif based on the heptad repeat in the amino acid sequence of all α-fibrous proteins (and parts of some globular proteins) is underlined by three Chapters devoted to its design, structure, function and topology. Specific proteins covered in the text and which depend on the coiled coil for their structure and function, include the intermediate filament proteins, tropomyosin, myosin, paramyosin, fibrin and members of the spectrin superfamily. Also described are fibrous proteins based on the β-pleated sheet and collagen conformations. Recombinant structural proteins, especially of silk and collagen, are discussed in the context of developing new biomaterials with varied applications. Established researchers and postgraduate students in the fields of protein chemistry, biochemistry and structural biophysics will find Fibrous Proteins: Structures and Mechanisms to be an invaluable collection of topical reviews that describe the basic advances made in the field of fibrous proteins over the past decade. This book, written by recognized authorities in the field, provides a clear account of the current status of fibrous protein research and, in addition, establishes the basis for deciding the most appropriate directions for future activity, including the applications of protein engineering and the commercial exploitation of new biomaterials.

Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Book excerpt: This book illustrates the importance and significance of Quorum sensing (QS), it’s critical roles in regulating diverse cellular functions in microbes, including bioluminescence, virulence, pathogenesis, gene expression, biofilm formation and antibiotic resistance. Microbes can coordinate population behavior with small molecules called autoinducers (AHL) which serves as a signal of cellular population density, triggering new patterns of gene expression for mounting virulence and pathogenesis. Therefore, these microbes have the competence to coordinate and regulate explicit sets of genes by sensing and communicating amongst themselves utilizing variety of signals. This book descry emphasizes on how bacteria can coordinate an activity and synchronize their response to external signals and regulate gene expression. The chapters of the book provide the recent advancements on various functional aspects of QS systems in different gram positive and gram negative organisms. Finally, the book also elucidates a comprehensive yet a representative description of a large number of challenges associated with quorum sensing signal molecules viz. virulence, pathogenesis, antibiotic synthesis, biosurfactants production, persister cells, cell signaling and biofilms, intra and inter-species communications, host-pathogen interactions, social interactions & swarming migration in biofilms.

This book was released on 2002-11-30 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The journey to find genes responsible for determining sensitivity or resistance to specific insecticides led to the paraoxonase (PON1) gene on human chromosome 7. This gene encodes a 355 amino acid protein that is localized on the high density lipoprotein (HDL) particles in plasma. Characterization of this gene revealed that different individuals expressed both different forms of this enzyme with amino acid substitutions at positions 55 and 192 as well as different levels of this protein. Additional studies showed that mutations in the regulatory region of the PON1 gene contributed to the very different levels of plasma PON1 among individuals. It turned out that both the level of the enzyme as well as the amino acid present at position 192 (glutamine or arginine) are important in determining resistance to the active forms of specific organophosphorus insecticides, especially diazinon and chlorpyrifos. The position 192 amino acid also determined whether an individual's plasma hydrolyzed the nerve agents soman and sarin at high or low rates. It is not yet known whether these different rates of hydrolysis observed in biochemical assays reflect differences in sensitivity of individuals to nerve agents. Taken together, all of the experiments carried out to date indicate that engineered recombinant PON1 is an excellent candidate to use for treating cases of poisoning by specific organophosphorus compounds. The available data on the relationship of PON1 levels and position 192 genotype led us to introduce the term PON1 status to describe an individual's PON1 plasma level as well as their position 192 genotype.The characterization of the genetic variations of the PON1 gene together with experiments showing that HDL can protect the lipids in low density lipoprotein particles (LDL) from oxidation and that it was PON1 that was responsible for this protection have opened an entirely new area of investigation, the role of PON1 in protecting against vascular disease.More recent reports have noted that PON1 also metabolizes a number of drugs, activating some and inactivating others.This book describes the recent advances in understanding the role of PON1 in both cardiovascular disease and toxicology of insecticide exposure as well as some of the recent information indicating an important possible role in the pharmacokinetics of drug metabolism. The final chapter of the book provides an overview of the areas of PON1 research and suggests future directions for research on PON1 as well as the related, linked genes PON2 and PON3.
