Download or read book Phenotypic screening in the 21st century written by Gul Erdemli and published by Frontiers Media SA. This book was released on 2015-04-21 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the genomic era of 1990s-2000s, pharmaceutical research moved to target-based drug discovery which enabled development of a number of small molecule drugs against a wide range of diseases. In many cases however, drugs that arose from genomics failed, questioning the validity of the targets and the suitability of target-based drug discovery as an optimal strategy for all disease states. For monogenic diseases, target-based approaches may be well-suited to the identification of novel therapies. Most diseases, however, are caused by a combination of several genetic and environmental factors and are likely to require simultaneous modulation of multiple molecular targets/pathways for successful treatment. For such diseases, reductionist approaches focusing on individual targets rather than biological networks are unlikely to succeed and new drug development strategies are required. In search of more successful approaches, the pharmaceutical industry is moving towards phenotypic screening beyond individual genes/targets. However, this requires rethinking of diseases and drug discovery approaches from a network and systems biology perspective. Since returning to the pre-genomics era of screening drug candidates in laborious animal models is not a feasible solution, the industry needs to evolve a new paradigm of phenotypic drug discovery within the context of systems biology. Such a paradigm must combine physiologically and disease relevant biological substrates with sufficient throughput, operational simplicity and statistical vigour. Biomarker strategies for translational medicine, as well as preclinical safety and selectivity assessments, would also need to be revised to adapt to the target agnostic style. This focused issue aims to discuss strategies, key concepts and technologies related to systems-based approaches in drug development. Design and implementation of innovative biological assays, featuring multiple target strategies, and rational drug design in the absence of target knowledge during the early drug discovery are illustrated with examples. Specific topics include: • The need for systems-based approaches in drug development • Phenotypic screening strategies • Compound libraries (natural product inspired compound collections) • Target deconvolution and identification • Target agnostic lead discovery and optimization • Multi-target approaches and decoding the phenotype (understanding biological interactions and multiscale systems modelling) • Translational aspects • Early evaluation of selectivity and safety in a target agnostic manner

Download or read book Tumor Organoids written by Shay Soker and published by Humana Press. This book was released on 2017-10-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Download or read book Toxicity Testing in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2007-10-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

Download or read book Cystic Fibrosis in the 21st Century written by Andrew Bush and published by Karger Medical and Scientific Publishers. This book was released on 2006 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cystic fibrosis used to be thought of as a respiratory and digestive disease, with a uniformly and rapidly fatal outcome. The spectrum of the disease has broadened into the mild atypical case, presenting in middle age, with the potential for complications in virtually every system of the body. In the past few years there has been an explosion of knowledge of the basic science of the defect. The editors have therefore invited the leading scientists and clinicians in the field of cystic fibrosis to describe the recent advances in this disease. Although there are many 'Recent Advances' texts, previous books have been selective in their choice of topics. This book is the first to cover the entire field of this complex disease, and encompasses the rapidly moving topics of the basic molecular and cellular biology as well as the recent multi-system, multi-disciplinary advances in the clinical care of patients. The authors have been charged with writing only about new developments and not to rehash old literature. The bulk of the references is therefore less than five years old. This book addresses all professionals who treat cystic fibrosis and want to have an up-date of new findings in the field, particularly of those outside their immediate specialisation. It will also be useful for basic researchers interested in related scientific areas and the clinical context of their work.

Download or read book Regenerative Medicine Technology written by Sean V. Murphy and published by CRC Press. This book was released on 2016-11-30 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Miniaturization in the fields of chemistry and molecular biology has resulted in the "lab-on-a-chip." Such systems are micro-fabricated devices capable of handling extremely small fluid volumes facilitating the scaling of single or multiple lab processes down to a microchip-sized format. The convergence of lab-on-a-chip technology with the field of cell biology facilitated the development of "organ-on-a-chip" systems. Such systems simulate the function of tissues and organs, having the potential to bypass some cell and animal testing methods. These technologies have generated high interest as applications for disease modeling and drug discovery. This book, edited by Drs. Sean Murphy and Anthony Atala, provides a comprehensive coverage of the technologies that have been used to develop organ-on-a-chip systems. Known leaders cover the basics to the most relevant and novel topics in the field, including micro-fabrication, 3D bio-printing, 3D cell culture techniques, biosensor design and microelectronics, micro-fluidics, data collection, and predictive analysis. The book describes specific tissue types amenable for disease modeling and drug discovery applications. Lung, liver, heart, skin and kidney "on-a-chip" technologies are included as well as a progress report on designing an entire "body-on-a-chip" system. Additionally, the book covers applications of various systems for modeling tissue-specific cancers, metastasis, and tumor microenvironments; and provides an overview of current and potential applications of these systems to disease modeling, toxicity testing, and individualized medicine.

This book was released on 2017-02-16 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, several large-scale United States and international programs have been initiated to incorporate advances in molecular and cellular biology, -omics technologies, analytical methods, bioinformatics, and computational tools and methods into the field of toxicology. Similar efforts are being pursued in the field of exposure science with the goals of obtaining more accurate and complete exposure data on individuals and populations for thousands of chemicals over the lifespan; predicting exposures from use data and chemical-property information; and translating exposures between test systems and humans. Using 21st Century Science to Improve Risk-Related Evaluations makes recommendations for integrating new scientific approaches into risk-based evaluations. This study considers the scientific advances that have occurred following the publication of the NRC reports Toxicity Testing in the 21st Century: A Vision and a Strategy and Exposure Science in the 21st Century: A Vision and a Strategy. Given the various ongoing lines of investigation and new data streams that have emerged, this publication proposes how best to integrate and use the emerging results in evaluating chemical risk. Using 21st Century Science to Improve Risk-Related Evaluations considers whether a new paradigm is needed for data validation, how to integrate the divergent data streams, how uncertainty might need to be characterized, and how best to communicate the new approaches so that they are understandable to various stakeholders.
