This book was released on 2014 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acidic tumor microenvironment exists in many types of cancer. Altered glycolytic metabolism of tumor cells and deficient blood supply in tissues are major causes for this phenomenon. Lymphoma cells may have different responses to chemotherapeutics when they are exposed to acidic tumor microenvironment. Bortezomib (BTZ) is a chemotherapeutic drug already approved by FDA for treating multiple myeloma and mantle cell lymphoma, which can inhibit the 26S proteasome and block the protein degradation process. Ramos parental cells (Human Burkitt's lymphoma cell line) and BTZ-resistant Ramos cells (obtained after chronic selection using low concentration of BTZ) were used in the study. Cells were treated from 2h to 24h with RPMI culture media buffered to pH 7.4 and pH 6.4, with or without chemical therapeutics. Cancer therapeutics tested in this study were BTZ, Cyclophosphamide, Doxorubicin, and ABT-737. MTT assay was utilized to detect cell viability under each treatment condition. Flow cytometry was used to examine changes on apoptosis and cell cycle. Western blots were performed to measure the changes of cellular protein levels. The MTT assays showed the acidic microenvironment could decrease cell proliferation rate, and if combined with BTZ treatment it could notably increase the cytotoxic efficacy of BTZ. After chronic selection under low concentration of BTZ, BTZ-resistant Ramos cells were obtained and were able to survive and grow in the presence of BTZ. However, acidic pH with BTZ could sensitize the BTZ-Resistant Ramos cells to BTZ again. Apoptosis assays demonstrated that acidic pH itself did not significantly induce cell apoptosis within 24h. But the combination of acidic pH with BTZ treatment caused much more apoptosis than BTZ alone. Cell cycle analysis showed that acidic pH could block the cell cycle, which led to cell cycle arrest and reduced percentage of cells in the G2/M phase. Western blots illustrated that acidic pH alone could upregulate the level of p53, Phospho-p53 at Ser15, Phospho-CHK1, Phospho-CHK2, pro-apoptotic proteins of the mitochondrial Bcl-2 family, and the pro-apoptotic Caspase family. In addition, if combined with BTZ treatment, acidosis could further increase phosphorylation of p53 at Ser15, expression of the Bcl-2 family proteins, and level of cleaved caspases. In conclusion, the combination of acidosis and BTZ treatment induce higher level of apoptosis and decrease Ramos cell proliferation. Our study demonstrates that arrested cell proliferation and increased apoptosis occur by the inhibition of cell cycle regulators and the activation of p53-mitochondria-caspase apoptosis pathways respectively.

Download or read book Oncothermia Principles and Practices written by Andras Szasz and published by Springer Science & Business Media. This book was released on 2010-11-23 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oncothermia is the next generation medical innovation that delivers selective, controlled and deep energy for cancer treatment. The basic principles for oncothermia stem from oncological hyperthermia, the oldest approach to treating cancer. Nevertheless, hyperthermia has been wrought with significant controversy, mostly stemming from shortcomings of controlled energy delivery. Oncothermia has been able to overcome these insufficiencies and prove to be a controlled, safe and efficacious treatment option. This book is the first attempt to elucidate the theory and practice of oncothermia, based on rigorous mathematical and biophysical analysis, not centered on the temperature increase. It is supported by numerous in-vitro and in-vivo findings and twenty years of clinical experience. This book will help scientists, researchers and medical practitioners in understanding the scientific and conceptual underpinnings of oncothermia and will add another valuable tool in the fight against cancer. Professor Andras Szasz is the inventor of oncothermia and the Head of St Istvan University's Biotechnics Department in Hungary. He has published over 300 papers and lectured at various universities around the world. Dr. Oliver Szasz is the managing director of Oncotherm, the global manufacturer and distributor of medical devices for cancer treatment used in Europe & Asia since the late 1980s. Dr. Nora Szasz is currently a management consultant in healthcare for McKinsey & Co.

These unique nanoscopic properties can either be accessed when the nanomaterials are prepared in the appropriate form, e.g., composites, or in integrated nanodevice form for direct use as electronic sensing devices. In both cases, the nanostructure has to be appropriately prepared, carefully handled, and properly integrated into the desired application in order to efficiently access its intelligent features. These aspects are reviewed in detail in three themed sections with relevant chapters: Nanomaterials, Fabrication and Biomedical Applications; Nanomaterials for Energy, Electronics, and Biosensing; Smart Nanocomposites, Fabrication, and Applications.

Download or read book The Heterogeneity of Cancer Metabolism written by Anne Le and published by Springer. This book was released on 2018-06-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.

Available in PDF, EPUB and Kindle. Book excerpt: This is book 2 of 5 of the “Understand Cancer” series. It is based on the best-available science. The SECONDARY causes of cancer were discussed in book one. This book continues from book one and discusses the PRIME cause of cancer as discovered by Nobel Prize Laureate Dr. Otto Warburg—considered by many as the founder of modern biochemistry. “There are prime and secondary causes of diseases. For example, the prime cause of the plague is the plague bacillus, but secondary causes of the plague are filth, rats, and the fleas that transfer the plague bacillus from rats to man. By a prime cause of a disease I mean one that is found in every case of the disease...Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one prime cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. All normal body cells meet their energy needs by respiration of oxygen, whereas cancer cells meet their energy needs in great part by fermentation. All normal body cells are thus obligate aerobes, whereas all cancer cells are partial anaerobes. From the standpoint of the physics and chemistry of life this difference between normal and cancer cells is so great that one can scarcely picture a greater difference. Oxygen gas, the donor of energy in plants and animals is dethroned in the cancer cells and replaced by an energy yielding reaction of the lowest living forms, namely, a fermentation of glucose.” —Dr. Otto Warburg

Download or read book Innovations for Next Generation Antibody Drug Conjugates written by Marc Damelin and published by Springer. This book was released on 2018-05-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody-drug conjugates (ADCs) stand at the verge of a transformation. Scores of clinical programs have yielded only a few regulatory approvals, but a wave of technological innovation now empowers us to overcome past technical challenges. This volume focuses on the next generation of ADCs and the innovations that will enable them. The book inspires the future by integrating the field’s history with novel strategies and cutting-edge technologies. While the book primarily addresses ADCs for solid tumors, the last chapter explores the emerging interest in using ADCs to treat other diseases. The therapeutic rationale of ADCs is strong: to direct small molecules to the desired site of action (and away from normal tissues) by conjugation to antibodies or other targeting moieties. However, the combination of small and large molecules imposes deep complexity to lead optimization, pharmacokinetics, toxicology, analytics and manufacturing. The field has made significant advances in all of these areas by improving target selection, ADC design, manufacturing methods and clinical strategies. These innovations will inspire and educate scientists who are designing next-generation ADCs with the potential to transform the lives of patients.
