Clark and published by . This book was released on 2017 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Late stage colorectal cancer (CRC) remains a challenging disease to treat due to several factors including stemness and epithelial to mesenchymal transition (EMT). Dysfunctional signaling pathways in CRC contribute to these phenomena, including the Notch and Transforming Growth Factor-Beta (TGF-[beta]) pathways. These pathways integrate external signals by cross-talking with one another to fine-tune cellular responses. We previously found that cells expressing constitutively active Notch1 also had increased expression of Smad3, an important member of the TGF-[beta] signaling pathway. Therefore, we hypothesized that the TGF-[beta] pathway, via Smad3, mediates the Notch-induced stemness and EMT observed in these cells. To test our hypothesis, we used the human colorectal carcinoma cell line HCT-116 and derivative cell lines GFP-v (a control cell line transfected with a retrovirus containing the green fluorescent protein), and ICN1 (a cell line transfected with a retrovirus containing both the green fluorescent protein and constitutively active intracytoplasmic Notch1). These cells were treated with different combinations of TGF-[beta]1 (a TGF-[beta] receptor ligand), DAPT (a [gamma]-secretase inhibitor), or SIS3 (a novel Smad3 inhibitor). Western blot procedures and statistical analysis were performed to determine the cross-talk between the Notch and TGF-[beta] pathways and to assess the effects of Smad3 stimulation and inhibition on Notch and its downstream targets. The role of Smad3 on colosphere formation was also determined using the aforementioned cell lines. Smad3 inhibition induced a decrease in Notch1 and Notch3 receptor expression. Additionally, SIS3 effectively inhibited key stemness and EMT markers such as CD44, Slug, Snail, and Hes1. Colosphere forming ability was also considerably reduced in cells treated with SIS3. These results indicate a key role of TGF-[beta] signaling in Notch1-induced tumorigenesis, and they also suggest a potential use for Smad3 inhibitors in combination with Notch1 inhibitors that are already in use for CRC treatments.

Book excerpt: Transforming growth factor-[beta] (TGF-[beta]), identified nearly three decades ago, is a secreted polypeptide that functions in critical cell cycle processes, including cellular proliferation, differentiation, and development: It belongs to a large protein family that, in humans, contains 33 members, including activins, inhibins, bone morphogenetic proteins, growth and differentiation factors, and Mullerian inhibiting substance. This volume draws on the world's leading laboratories to comprehensively cover all aspects of the biology of TGF-[beta] and related factors. In addition to providing historical and background information, it describes the cell biology and signaling pathways of TGF-[beta] members in detail, including the roles of TGF-[beta] factors in the development and physiology of humans and model organisms. The last few chapters are devoted to the role of TGF-[beta] members in cancer and other diseases, as well as the possibilities for therapeutics based on knowledge of signaling pathways and macromolecular structures. It serves as a comprehensive reference work for both specialists and researchers less familiar with the field.

This book was released on 2015 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colorectal cancer is the third most commonly diagnosed cancer in both men and women in the United States. Surgical resection and combination chemotherapy are often used for treatment, but in later stages of the disease, these therapies are often unsuccessful. Previous studies have revealed that circulating cancer cells with stem-cell like properties are associated with disease progression and metastatic potential. The Notch signaling pathway has been found to be critical for proliferation and proper functioning in the stem cell compartment of the colon. Preliminary studies from our lab have shown a marked increase in Notch-1 levels from colon tumor tissue as compared to normal colon tissue. This study hypothesizes that overexpression of Notch-1 signaling in colon cancer results in enhanced Epithelial to Mesenchymal Transition (EMT) and stemness mediated by other Notch family members via the Jagged-1 ligand. Overexpression of Notch-1 resulted in a cell phenotype which resembles that of a cancer stem cell, with a slower dividing time, and enhanced aggressiveness. Furthermore, cells with constitutively active Notch-1 overexpressed proteins associated with stemness and EMT such as CD44 and Slug. The results which we obtained provide an indication that Notch signaling plays a significant role in the upregulation of EMT and stemness in colon cancer.

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.

Available in PDF, EPUB and Kindle. Book excerpt: “Precision/personalized or stratified medicine” refers to the tailoring of medical treatment or drug administration to the individual characteristics of each patient treatment. It does not literally mean that a pharmaceutical company makes a drug for an individual patient for consumption and treatment but rather means the ability to stratify (or classify) individuals into sub-populations that differ in their responsiveness to a specific drug. A marker that provides information on the likely response to therapy, i.e., either in terms of tumor shrinkage or survival of the patient is termed “predictive biomarker”. Despite their promise in precision medicine and the explosion of knowledge in this area, there is not a single source on this subject that puts all this evidence together in a concise or richly illustrated and easy to understand manner. This book provides a collection of ingeniously organized, well-illustrated and up-to-date authoritative chapters divided into five sections that are clear and easy to understand. Section one provides an overview of biomarkers, introduces the basic terminologies, definitions, technologies, tools and concepts associated with this subject in the form of illustrations/graphics, photographs and concise texts. Several recent biomarker endeavors that have been initiated and funded by the National Cancer Institute, National Institutes of Health, FDA and other International organizations are presented. Section two involves the signaling pathways controlling cell growth and differentiation altered in cancer. This section analyzes how predictive biomarkers are altered (expressed or amplified) across cancer types. Section three explores how predictive biomarkers play a role in patient stratification and tailored treatment in relationship to specific cancers. In addition, it includes discussion on the various precision medicine initiatives that are going on across the globe (e.g. TARGET, NCI-MATCH, BATTLE, SHIVA, etc.). Section four discusses: (a) how pharmaceutical companies validate predictive biomarker assays and accompanying companion diagnostics either internally or externally with partner companies such as central laboratories or clinical research organizations, and (b) how predictive biomarker tests fall under the oversight of US FDA, Centers for Medicare & Medicaid Services (CMS) and state laws. Section five wraps up novel agents and targets that are being used as targets for cancer therapeutics. The biomarkers associated with these protocols will also be presented. Throughout the book, sidebars, special interest boxes and illustrations are used to explain terms that are either newly introduced, uncommon, or specialized. Predictive Biomarkers in Oncology will serve as a definitive guide for practicing pathologists, oncologists, basic researchers, and personnel in the pharmaceutical or diagnostic industry interested in learning how “predictive biomarkers” are used in precision cancer therapy.

Book excerpt: This book gives insight into the functional role of non-coding RNAs in central pathways contributing to the development of obesity, type 2 diabetes, non-alcoholic fatty liver disease, atherosclerosis, myocardial infarction, cardiomyopathy, and heart failure. It also sheds light on the relationship of this cluster with cancer. Tumor cells, in contrast to cells in cardiometabolic tissues, can regulate this cluster of non-coding RNAs to escape from oxidative stress and anti-tumor immunity and maintain insulin sensitivity, facilitating cancer progression. The book presents a cluster of non-coding RNAs that may be prospectively analyzed in extensive cohort studies to determine their value in risk-predicting machine learning algorithms. In addition, it emphasizes the role of microvesicles in communication between tumor-adjacent tissue, inflammatory cells, and tumor cells, with a special focus on the role of miR-155. The book intends to promote interdisciplinary research. Due to the comprehensive background information provided in each chapter, it is suitable for researchers in academia and industry and for graduate students in biology, bioengineering, and medicine.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The human body contains many specialized tissues that are capable of fulfilling an incredible variety of functions necessary for our survival. This volume in the Human Cell Culture Series focuses on mesenchymal tissues and cells. The in vitro study of mesenchymal cells is perhaps the oldest form of human cell culture, beginning with the culturing of fibroblasts. Fibroblasts have long been generically described in the literature, arising from many tissue types upon in vitro cell culture. However, recent studies, many enabled by new molecular biology techniques, have shown considerable diversity in fibroblast type and function, as described within this volume. Mesenchymal tissue types that are described within include bone, cartilage, tendons and ligaments, muscle, adipose tissue, and skin (dermis). The proper function of these tissues is predominantly dependent upon the proper proliferation, differentiation, and function of the mesenchymal cells which make up the tissue. Recent advancements in primary human mesenchymal cell culture have led to remarkable progress in the study of these tissues. Landmark experiments have now demonstrated a stem cell basis for many of these tissues, and, furthermore, significant plasticity and inter-conversion of stem cells between these tissues, resulting in a great deal of contemporary excitement and controversy. Newly-developed mesenchymal cell culture techniques have even lead to novel clinical practices for the treatment of disease.

This book was released on 2019-03-26 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene cloning and sequence has provided the opportunity to identify and characterize the functional role of biomarkers expressed in and on tumor cells and the surrounding microenvironment. Molecular and immunologic heterogeneity of cells in the tumor microenvironment contributes to instability, enhanced angiogenesis, and drug resistance of the tumor cell. Since tumor cells are the ultimate therapeutic targets for drugs and therapy development, the tumor microenvironment that regulates the growth and the delivery of effective drug concentrations to tumor cells is the gatekeeper. Thus, to have a significant impact on the overall survival and cure of patients with advanced cancer, the stabilization of the tumor microenvironment should be the initial treatment, followed by treatment that targets and kills tumor cells. Antiangeogenic therapies hold considerable promise in the treatment of a subset of cancer patients and are reported to have a significant impact on the stabilization of the tumor microenvironment. More recently, selenium-containing molecules, such as se-metylselenocysteine, seleno-L-methionine, and selenized yeast, among others, have been shown to target and modulate biomarkers associated with tumor cells and the tumor microenvironment. The effects are selenium type-, dose-, and schedule-dependent. The pleiotropic actions of selenium are necessary for tumor cell sensitization, and synergy with mechanism-based combinations. This Special Issue is devoted to highlighting evidence for the potential role of specific types, doses, and schedules of selenium alone and in combination with mechanism-based biologic and cytotoxic therapies for the prevention and treatment of cancer and related diseases. The collection of contributions should provide a comprehensive overview of the pharmacology, metabolism, and delineation of the pleiotropic action of different types of selenium molecules, relevant to the use of selenium as a potential modulator of the therapeutic efficacy and toxicity of biologic and cytotoxic therapies for cancer and related diseases. The pleiotropic action of specific types of selenium, doses, and schedule, as a selective and efficacious modulator of genetic, immunologic, and epigenetic biomarkers, should stimulate expanded preclinical research that could ultimately impact the development of new and novel approaches for the treatment of cancer.

Available in PDF, EPUB and Kindle. Book excerpt: This volume – for pharmacologists, systems biologists, philosophers and historians of medicine – points to investigate new avenues in pharmacology research, by providing a full assessment of the premises underlying a radical shift in the pharmacology paradigm. The pharmaceutical industry is currently facing unparalleled challenges in developing innovative drugs. While drug-developing scientists in the 1990s mostly welcomed the transformation into a target-based approach, two decades of experience shows that this model is failing to boost both drug discovery and efficiency. Selected targets were often not druggable and with poor disease linkage, leading to either high toxicity or poor efficacy. Therefore, a profound rethinking of the current paradigm is needed. Advances in systems biology are revealing a phenotypic robustness and a network structure that strongly suggest that exquisitely selective compounds, compared with multitarget drugs, may exhibit lower than desired clinical efficacy. This appreciation of the role of polypharmacology has significant implications for tackling the two major sources of attrition in drug development, efficacy and toxicity. Integrating network biology and polypharmacology holds the promise of expanding the current opportunity space for druggable targets.

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.
