Download or read book Oncogenic PI3KT Akt mTOR Pathway Alterations ROS Homeostasis Targeted Cancer therapy and drug resistance written by Rozangela Curi Pedrosa and published by Frontiers Media SA. This book was released on 2024-02-23 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway is an important signaling route that regulates several cell functions. PI3K/AKT/mTOR pathway is a crossroad of cell death and survival, playing a pivotal role in multiple interconnected cell signaling mechanisms implicated in cell metabolism, growth and proliferation, apoptosis, and angiogenesis. Disruptions in the Akt‑regulated pathways and alterations in PTEN expression are associated to Reactive oxygen species (ROS) homeostasis and different types of cancer. Genomic studies have shown that activating mutations in oncogenes as well as inactivating mutations in tumor suppressor genes are present across a variety of malignancies, including constitutive activation of the PI3K/AKT/mTOR pathway. The regulation of the Akt signaling pathway renders multiple challenges and valuable therapeutic targets. The discovery process of Akt, PDK1 and mTOR synthetic and natural products as inhibitors or immune checkpoint inhibitors using various strategies, could led to the identification of small molecule inhibitors with great selectivity, low side‑effects and also low toxicity regarding drug development.
Download or read book New Prognostic and Predictive Markers in Cancer Progression written by Susan Costantini Alfredo Budillon and published by MDPI. This book was released on 2021-02-12 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomarkers are of critical medical importance for oncologists, allowing them to predict and detect disease and to determine the best course of action for cancer patient care. Prognostic markers are used to evaluate a patient’s outcome and cancer recurrence probability after initial interventions such as surgery or drug treatments and, hence, to select follow-up and further treatment strategies. On the other hand, predictive markers are increasingly being used to evaluate the probability of benefit from clinical intervention(s), driving personalized medicine. Evolving technologies and the increasing availability of “multiomics” data are leading to the selection of numerous potential biomarkers, based on DNA, RNA, miRNA, protein, and metabolic alterations within cancer cells or tumor microenvironment, that may be combined with clinical and pathological data to greatly improve the prediction of both cancer progression and therapeutic treatment responses. However, in recent years, few biomarkers have progressed from discovery to become validated tools to be used in clinical practice. This Special Issue comprises eight review articles and five original studies on novel potential prognostic and predictive markers for different cancer types.
Download or read book PI3K mTOR in Cancer and Cancer Therapy written by Nandini Dey and published by Humana. This book was released on 2018-05-31 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the post human-genome project era, cancer specific genomic maps are redesigning tumor taxonomy by evolving from histopathology to molecular pathology. The success of a cancer drug today is fundamentally based on the success in identifying target genes that control beneficial pathways. The overwhelming power of genomics and proteomics has enlightened researchers about the fact that the PI3K-mTOR pathway is the most commonly up-regulated signal transduction pathway in various cancers, either by virtue of its activation downstream of many cell surface growth factor receptors or by virtue of its collateral and compensatory circuitry with RAS-MAPK pathway. Oncogenic signaling in the majority of solid tumors is sustained via the PI3K-AKT-mTOR pathway. Because of its prominent role in many cancer types, the PI3K-mTOR pathway has become a major therapeutic target. The volume includes two complementary parts which address the problem of etiology and disease progression and is intended to portray the very basic mechanisms of the PI3K-AKT-mTOR signaling pathway’s involvement in various facets of the cancer, including stem cell renewal, cell metabolism, angiogenesis, genetic instability, and drug resistance. Significant progress has been made in recent years elucidating the molecular mechanism of cancer cell proliferation, angiogenesis, and drug-resistance in relation to the PI3K-mTOR pathway and this volume provides an in-depth overview of recent developments made in this area.
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.

Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."
Download or read book PI3K signalling written by Klaus Okkenhaug and published by Frontiers Media SA. This book was released on 2015-03-05 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PI3Ks control many key functions in immune cells. PI3Ks phosphorylate PtdIns(4,5)P2 to yield PtdIns(3,4,5)P3. Initially, PI3K inhibitors such as Wortmannin, LY294002 and Rapamycin were used to establish a central role for Pi3K pathway in immune cells. Considerable progress in understanding the role of this pathway in cells of the immune system has been made in recent years, starting with analysis of various PI3K and Pten knockout mice and subsequently mTOR and Foxo knockout mice. Together, these experiments have revealed how PI3Ks control B cell and T cell development, T helper cell differentiation, regulatory T cell development and function, B cell and T cell trafficking, immunoglobulin class switching and much, much more. The PI3Kd inhibitor idelalisib has recently been approved for the treatment of B cell lymphoma. Clinical trials of other PI3K inhibitors in autoimmune and inflammatory diseases are also in progress. This is an opportune time to consider a Research Topic considering when what we have learned about the PI3K signalling module in lymphocyte biology and how this is making an impact on clinical immunology and haematology.
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.

Download or read book Metabolism in Cancer written by Thorsten Cramer and published by Springer. This book was released on 2016-08-24 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents concise chapters written by internationally respected experts on various important aspects of cancer-associated metabolism, offering a comprehensive overview of the central features of this exciting research field. The discovery that tumor cells display characteristic alterations of metabolic pathways has significantly changed our understanding of cancer: while the first description of tumor-specific changes in cellular energetics was published more than 90 years ago, the causal significance of this observation for the pathogenesis of cancer was only discovered in the post-genome era. The first 10 years of the twenty-first century were characterized by rapid advances in our grasp of the functional role of cancer-specific metabolism as well as the underlying molecular pathways. Various unanticipated interrelations between metabolic alterations and cancer-driving pathways were identified and currently await translation into diagnostic and therapeutic applications. Yet the speed, quantity, and complexity of these new discoveries make it difficult for researchers to keep up to date with the latest developments, an issue this book helps to remedy.
