Abstract: Abstract of thesis entitled STRUCTURAL AND FUNCTIONAL STUDIES OF THE NEURONAL GROWTH INHIBITORY FACTOR, HUMAN METALLOTHIONEIN-3 Submitted by WANG Hui for the degree of Doctor of Philosophy at The University of Hong Kong in August 2007 Alzheimer's disease (AD) is characterized by progressive loss of neurons accompanied by the formation of intraneural neurofibrillary tangles and extracellar amyloid plaques. The brain specific member of the metallothionein (MT) family, metallothionein-3 inhibits the growth and survival of neurons whose down-regulation can lead to the enhancement of neurotrophic activity in Alzheimer Disease's brain. Due to the distinct biological activity, MT-3 is also identified as a growth inhibitory factor (GIF). The solution structure of the α-domain of human MT-3 (residue 32-68) has been determined by multinuclear and multidimensional NMR spectroscopy in combination with the molecular dynamic simulated annealing approach. Human MT-3 shows two metal-thiolate clusters, the M Cys cluster in the N-terminus (β-domain) and the M Cys 3 9 4 11 cluster in the C-terminus (α-domain). The overall fold of the α-domain is similar to that of mouse MT-3. However, human MT-3 has a longer loop in the acidic hexapeptide insertion than that of mouse MT-3. Surprisingly, the backbone dynamics of the protein revealed that the β-domain exhibits similar internal motion to the α-domain, although the N-terminal residues are more flexible. With additional residual dipolar couplings (RDCs), the structure refinements of the two domains were performed respectively. For the α-domain, after refinement, the overall fold is essentially identical to that obtained without such RDCs constraints only with a slight movement in the acidic loop towards the metal ions. On the other hand, for the β-domain, the additional two sets of RDCs make it possible to determine the structure of the flexible β-domain, and the refined structures of the β-domain showed a different 113 overall fold from other MTs. Furthermore, Cd NMR studies on the mutants P7SP9A- hMT-3 and C30S/∆33-35-hMT-3 revealed their different characteristics of the metal- thiolate clusters. It is known that nitric oxide (NO) has a pivotal role in zinc toxicity in neurons. The nitrosylation of thiols in metallothioneins (MTs), which is mediated by NO, possibly results in the 'somatic' zinc release by destroying the metal-thiolate clusters. By using 113 1 15 Cd and 2D [ H, N] HSQC NMR spectroscopy, the NO-induced metal release from human MT-3 was examined, and the structural changes associated with the interaction was monitored. The NMR technique allows the individual metal release from the protein and the associated structural changes of the protein at level of individual residue to be monitored. The exposure of human MT-3 to NO leads to a non-selective release of the three metals from the β-domain. In contrast to MT-1/2, two of the bound metals in the α- domain were also partially released with the domain structure remained almost unchanged. Further addition of NO resulted in complete release of metals and concomitant unfolding of the protein. The preference of metal release in the α-domain was attributed to the two different coordination environment for the four cadmium/zinc atoms. The results of the structural and biochemical studies may provide useful informa

Download or read book Metallothioneins in Biochemistry and Pathology written by Paolo Zatta and published by World Scientific. This book was released on 2008 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallothioneins (MTs) represent a large family of proteins characterized by high heavy metal content (mainly CuII and ZnII) and by an unusual cysteine abundance. They have a powerful protective function in all animal tissues, due most likely to their properties as free radical scavengers protecting against oxidative damage. Moreover, the presence and overexpression of MTs in various pathological conditions, such as metal dyshomeostasis, cell proliferation, neurological disorders, and chemotherapy and radiotherapy resistance, could be used as an important prognostic marker, as a histopathological diagnostic tool, and to follow specific pharmacological treatments.This important book explores the role of MTs in the field of neurological disorders (brain inflammation, Alzheimer's and prion diseases, autism, ALS, etc.), cardiology (cardiomyopathy, atherosclerosis), and oncology (melanoma, prostate and breast cancer), through authoritative contributions and a description of basic biochemical information and paradigmatic pathological events.

This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Download or read book The Claustrum written by John R. Smythies and published by Academic Press. This book was released on 2013-11-11 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present day is witnessing an explosion of our understanding of how the brain works at all levels, in which complexity is piled on complexity, and mechanisms of astonishing elegance are being continually discovered. This process is most developed in the major areas of the brain, such as the cortex, thalamus, and striatum. The Claustrum instead focuses on a small, remote, and, until recently, relatively unknown area of the brain. In recent years, researchers have come to believe that the claustrum is concerned with consciousness, a bold hypothesis supported by the claustrum's two-way connections with nearly every other region of the brain and its seeming involvement with multisensory integrations—the hallmark of consciousness. The claustrum, previously in a humble position at the back of the stage, might in fact be the conductor of the brain's orchestra. The Claustrum brings together leading experts on the claustrum from the varied disciplines of neuroscience, providing a state-of-the-art presentation of what is currently known about the claustrum, promising lines of current research (including epigenetics), and projections of new lines of investigation on the horizon. - Develops a unifying hypothesis about the claustrum's role in consciousness, as well as the integration of sensory information and other higher brain functions - Discusses the involvement of the claustrum with autism, schizophrenia, epilepsy, Alzheimer's disease, and Parkinson's disease - Coverage of all aspects of the claustrum, from its evolution and development to promising new lines of research, including epigenetics, provides a platform and point of reference for future investigative efforts
