Available in PDF, EPUB and Kindle. Book excerpt: Nrf2 (NF-E2-related factor 2) is a transcription factor that regulates a battery of downstream genes that contain the antioxidant response element (ARE) in their promoter regions, including intracellular redox-balancing proteins, phase II detoxifying enzymes, and transporters. These Nrf2-dependent proteins work in collaboration to protect against many diseases where oxidative stress plays an essential role in disease onset and progression. Consequently, it is imperative to understand the basic molecular mechanisms of how Nrf2 is regulated so that this pathway can be targeted for disease prevention and treatment. Nrf2 is mainly regulated at the protein level by the ubiquitin proteasome system. Under basal conditions Nrf2 is constantly ubiquitinated by the Keap1-Cul3-E3 ubiquitin ligase complex and subsequently degraded by the 26S proteasome. Currently, regulation of the Nrf2-Keap1 pathway by ubiquitination is largely understood. However, other mechanism responsible for modulating Nrf2-ARE signal remains to be explored. This dissertation identifies three molecular mechanisms that are important in understanding how the Nrf2-Keap1 pathway is regulated: (i) In Chapter 2, KPNA6 was identified and characterized as a negative regulatory mechanism of the Nrf2 pathway, which mediates Keap1 nuclear import and represses the Nrf2-dependent antioxidant response at post-induction phase. (ii) In Chapter 3, I identified PARP-1 as a new transcription co-activator of Nrf2, which augments ARE-specific DNA binding of Nrf2 and enhances the transcription of Nrf2 target genes. This indicates a novel function of PARP-1 and reveals another layer of regulation of Nrf2. (iii) In Chapter 4, I demonstrated that XBP1 and SYVN1 are involved in regulating the Nrf2 pathway in a Keap1-independent mechanism. During ER stress, XBP1s upregulates transcription of SYVN1, which is an ubiquitin E3 ligase. SYVN1 accelerates the clearance of Nrf2 protein through promoting ubiquitination of Nrf2, and subsequent proteasomal degradation. Moreover, we observed an inverse correlation between XBP1s/SYVN1 and Nrf2 expression in the end stage alcoholic cirrhosis liver samples, implying a pathological role of ER stress-oxidative stress crosstalk. Taken together, these findings further our understanding of how the Nrf2-Keap1 pathway is regulated, providing novel targets of chemoprevention or chemotherapy.
Book Synopsis A Master Regulator of Oxidative StressThe Transcription Factor Nrf2 by : Jose Antonio Morales-Gonzalez
Download or read book A Master Regulator of Oxidative StressThe Transcription Factor Nrf2 written by Jose Antonio Morales-Gonzalez and published by BoD – Books on Demand. This book was released on 2016-12-21 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to that at present, the majority of diseases are associated with alterations in oxidative stress and inflammatory processes, and in that Nrf-2 is a modulator of these processes; knowing how this transcriptional factor functions and is regulated opens a therapeutic window to diverse diseases. Therefore, the efforts of various investigation groups are centered on finding activators and/or inhibitors of Nrf-2 to prevent or control diverse diseases, for example, cancer, where it would be important to regulate Nrf-2 in order for it to activate apoptosis pathways in cancerogenous cells, or in neurodegenerative diseases where cell death is predominant, it would be important for Nrf-2 to activate antiapoptotic pathways.

Book Synopsis Innovative Medicine by : Kazuwa Nakao
Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.

This Research Topic will focus on the interaction of gaseous molecules with ion channels/transporters and will address the following questions: i) Which ion channels/transporters are regulated by gases? ii) How are ion channels/transporters mechanistically regulated by gases? iii) What are cellular and physiological processes, which are triggered by the interaction of gases with ion channels/transporters?
Download or read book Hypoxia in Kidney Disease written by and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kidney disease is a complex health problem, often coinciding with cardiovascular pathology (e.g. hypertension) and metabolic disturbances (e.g. obesity and diabetes). It is also a disturbingly fast growing global public health problem, e.g. chronic kidney disease affects an estimated ~9-16% of the population. Besides the public health issues this results in a large economic burden as kidney diseases contributes disproportionally to about a quarter of total health care costs. Experimental and clinical data solidly support the view that kidney tissue hypoxia plays a critical and intricate role during the genesis and progression of both chronic and acute kidney diseases. This research field is currently at the very beginning of integrating pre-clinical with clinical research in which hypoxia related mechanism are quantified by non-invasive imaging. In combination with the fact that some key questions remain unanswered, this offers exciting new research perspectives that are waiting to be explored. With this Research Topic we aim to discuss and find answers to the following research question: 1) What are the temporal relationships between hypoxia and kidney disease? 2) Can we demonstration causation between hypoxia and kidney disease? 3) Can renal hypoxia be considered as a treatment target in kidney disease? 4) Can hypoxia (e.g. in the urine) be considered a biomarker of kidney disease? 5) Does hypoxia ramp-up sympathetic activity? 6) Does hypoxia trigger inflammation? 7) Is hypoxia caused by changes in sodium reabsorption and/or mitochondrial function? 8) Which molecular mechanisms are involved in hypoxia in kidney disease? 9) Which gene expressions change due to hypoxia in kidney disease? 10) Can we generate new and translational insights using non-invasive imaging technologies? Our overall aim is identify the mediators/controllers of hypoxia in kidney disease. If we understand more about the sequence of events leading to hypoxia, its regulation and consequences in renal disease, we might be able to have a major impact in clinical practice. I.e. more accurate and earlier diagnosis, novel treatment targets, and novel therapies.

Book Synopsis Membrane Biogenesis by : Jos A.F. Op den Kamp
Download or read book Membrane Biogenesis written by Jos A.F. Op den Kamp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many individual aspects of the dynamics and assembly of biological membranes have been studied in great detail. Cell biological approaches, advanced genetics, biophysics and biochemistry have greatly contributed to an increase in our knowledge in this field.lt is obvious however, that the three major membrane constituents - lipids, proteins and carbohydrates- are studied, in most cases separately and that a coherent overview of the various aspects of membrane biogenesis is not readily available. The NATO Advanced Study Institute on "New Perspectives in the Dynamics of Assembly of Biomembranes" intended to provide such an overview: it was set up to teach students and specialists the achievements obtained in the various research areas and to try and integrate the numerous aspects of membrane assembly into a coherent framework. The articles in here reflect this. Statting with detailed contributions on phospholipid structure, dynamics, organization and biogenesis, an up to date overview of the basic, lipidic backbone of biomembranes is given. Extensive progress is made in the research on membrane protein biosynthesis. In particular the post- and co-translational modification processes of proteins, the mechanisms of protein translocation and the sorting mechanisms which are necessary to direct proteins to their final, intra - or extracellular destination have been characterized in detail. Modern genetic approaches were indispensable in this research area: gene cloning, hybrid protein construction, site directed mutagenesis and sequencing techniques elucidated many functional aspects of specific nucleic acid and amino acid sequences.
