Available in PDF, EPUB and Kindle. Book excerpt: Cancer cells can be dormant and then reawakened to cause cancer progression with new mutations and resistance. The stiffness associated with the extracellular matrix regulates many cellular functions, such as proliferation, apoptosis, and tumor development. Typically, an increased extracellular matrix stiffness is associated with breast cancer. We synthesized hydrogels that mimic the extracellular matrix stiffness of healthy and diseased breast tissue. The soft hydrogels have a Young's modulus of ~470 Pa, similar to healthy mammary tissue, and the stiffened hydrogels have a Young's modulus of ~3600 Pa, similar to breast tumor tissue. MDA-MB-231 breast cancer cells were plated onto soft hydrogels, and the hydrogels were then stiffened using light irradiation and a photoinitiator to form hydrogels with a stiffness mimicking mammary tumors. Ki67, a protein marker of proliferation, was monitored using immunofluorescence staining, microscopy, and image analysis. The activity of caspase-3, a protein that measures apoptosis, was analyzed using an activity kit and a plate reader. The static soft hydrogels were seen to have rounded cells, while the stiffened hydrogels were seen to have cells that were elongated. Quantitively, there was an increase in the percentage of Ki67-positive cells following stiffening of the hydrogels in comparison to when the cells were cultured on the soft hydrogels, indicating the cells waking up from their dormant state. When monitoring caspase-3 activity, cells cultured on the soft hydrogels had higher levels of caspase-3 activity than cells cultured on the stiffened hydrogels. Less caspase-3 activity on the stiffened hydrogels suggests less apoptosis.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed an increasing number of theoretical and experimental contributions to cancer research from different fields of physics, from biomechanics and soft-condensed matter physics to the statistical mechanics of complex systems. Reviewing these contributions and providing a sophisticated overview of the topic, this is the first book devoted to the emerging interdisciplinary field of cancer physics. Systematically integrating approaches from physics and biology, it includes topics such as cancer initiation and progression, metastasis, angiogenesis, cancer stem cells, tumor immunology, cancer cell mechanics and migration. Biological hallmarks of cancer are presented in an intuitive yet comprehensive way, providing graduate-level students and researchers in physics with a thorough introduction to this important subject. The impact of the physical mechanisms of cancer are explained through analytical and computational models, making this an essential reference for cancer biologists interested in cutting-edge quantitative tools and approaches coming from physics.
Book Synopsis Cancer Cell Lines Part 1 by : John Masters
Download or read book Cancer Cell Lines Part 1 written by John Masters and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous cell lines derived from human cancers are the most widely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions of fundamental importance to the relevance of human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative of tumors at that site is naïve and misleading.

This book was released on 2000-07-06 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In November 1999, the Institute of Medicine, in consultation with the Commission on Life Sciences, the Commission on Physical Sciences, Mathematics, and Applications, and the Board on Science, Technology and Economic Policy launched a one year study on technologies for early detection of breast cancer. The committee was asked to examine technologies under development for early breast cancer detection, and to scrutinize the process of medical technology development, adoption, and dissemination. The committee is gathering information on these topics for its report in a number of ways, including two public workshops that bring in outside expertise. The first workshop on "Developing Technologies for Early Breast Cancer Detection" was held in Washington DC in February 2000. The content of the presentations at the workshop is summarized here. A second workshop, which will focus on the process of technology development and adoption, will be held in Washington, DC on June 19-20. A formal report on these topics, including conclusions and recommendations, will be prepared by the committee upon completion of the one-year study.

Download or read book Epithelial-Mesenchymal Plasticity in Cancer Metastasis written by Mohit Kumar Jolly and published by MDPI. This book was released on 2020-12-29 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have highlighted that epithelial-mesenchymal transition (EMT) is not only about cell migration and invasion, but it can also govern many other important elements such as immunosuppression, metabolic reprogramming, senescence-associated secretory phenotype (SASP), stem cell properties, therapy resistance, and tumor microenvironment interactions. With the on-going debate about the requirement of EMT for cancer metastasis, an emerging focus on intermediate states of EMT and its reverse process mesenchymal-epithelial transition (MET) offer new ideas for metastatic requirements and the dynamics of EMT/MET during the entire metastatic cascade. Therefore, we would like to initiate discussions on viewing EMT and its downstream signaling networks as a fulcrum of cellular plasticity, and a facilitator of the adaptive responses of cancer cells to distant organ microenvironments and various therapeutic assaults. We hereby invite scientists who have prominently contributed to this field, and whose valuable insights have led to the appreciation of epithelial-mesenchymal plasticity as a more comprehensive mediator of the adaptive response of cancer cells, with huge implications in metastasis, drug resistance, tumor relapse, and patient survival.
