Download or read book Investigating Neurodegenerative Diseases with Small Molecule Modulators written by Reka Rebecca Letso and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This was exemplified by a screen for small molecule inhibitors of cell death caused by a pathogenic, misofolded mutant huntingtin protein in a cell culture model of Huntington's Disease (HD). These cell death inhibitors were found to target protein disulfide isomerase (PDI), an oxidoreductase known to be important in endoplasmic reticulum quality control of protein folding. However, our studies utilizing the small molecule PDI inhibitors determined that the cell death observed in this system was due to a pro-apoptotic function of PDI involving proteins of the mitochondrial outer membrane. We have begun studies aimed at identifying the binding mode of these novel small molecule inhibitors of PDI, in efforts to develop more potent and efficacious analogs for testing in animal models of HD. These studies have helped defined a novel mechanism linking protein misfolding to cell death, and may prove to be relevant to a broader range of protein misfolding diseases.
Download or read book Oxidative Stress and Neurodegenerative Disorders written by G. Ali Qureshi and published by Elsevier. This book was released on 2007-03-22 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders.* Contains the latest information on the subject of neurodegenerative disorders* Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems

Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

Download or read book Discovery of Small Molecule Modulators of Protein RNA Interactions for Treating Cancer and COVID 19 written by Wan Gi Byun and published by Springer Nature. This book was released on 2022-12-13 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of novel protein–RNA-binding assays and their applications in a high-throughput manner for the identification of small-molecule modulators of protein–RNA interactions to treat cancer and COVID-19. Modulating protein–RNA interactions with small molecules is expected to provide novel biological insights of the interrelation of diseases with the protein–RNA interactome. The modulations may also be exploited therapeutically. For these reasons, the development of a simple, reliable, and sensitive protein–RNA-binding assay is necessary for high-throughput screening to discover new effective chemical entities capable of acting on diverse protein–RNA interactions. This book discusses the discovery of small-molecule modulators targeting protein–RNA interactions that are potentially valuable to treat cancer and COVID-19 by constructing novel high-throughput screening methods. The results of this dissertation provide valuable insights into the regulation of protein–RNA interactions in chemical biology and drug development.

Download or read book Polyglutamine Disorders written by Clévio Nóbrega and published by Springer. This book was released on 2018-02-09 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17). The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.
