Book Exploring Cancer Metabolic Reprogramming through Molecular Imaging

Download or read book Exploring Cancer Metabolic Reprogramming through Molecular Imaging written by Franca Podo and published by Frontiers Media SA. This book was released on 2017-07-27 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inclusion of oncogene-driven reprogramming of energy metabolism within the list of cancer hallmarks (Hanahan and Weinberg, Cell 2000, 2011) has provided major impetus to further investigate the existence of a much wider metabolic rewiring in cancer cells, which not only includes deregulated cellular bioenergetics, but also encompasses multiple links with a more comprehensive network of altered biochemical pathways. This network is currently held responsible for redirecting carbon and phosphorus fluxes through the biosynthesis of nucleotides, amino acids, lipids and phospholipids and for the production of second messengers essential to cancer cells growth, survival and invasiveness in the hostile tumor environment. The capability to develop such a concerted rewiring of biochemical pathways is a versatile tool adopted by cancer cells to counteract the host defense and eventually resist the attack of anticancer treatments. Integrated efforts elucidating key mechanisms underlying this complex cancer metabolic reprogramming have led to the identification of new signatures of malignancy that are providing a strong foundation for improving cancer diagnosis and monitoring tumor response to therapy using appropriate molecular imaging approaches. In particular, the recent evolution of positron emission tomography (PET), magnetic resonance spectroscopy (MRS), spectroscopic imaging (MRSI), functional MR imaging (fMRI) and optical imaging technologies, combined with complementary cellular imaging approaches, have created new ways to explore and monitor the effects of metabolic reprogramming in cancer at clinical and preclinical levels. Thus, the progress of high-tech engineering and molecular imaging technologies, combined with new generation genomic, proteomic and phosphoproteomic methods, can significantly improve the clinical effectiveness of image-based interventions in cancer and provide novel insights to design and validate new targeted therapies. The Frontiers in Oncology Research Topic “Exploring Cancer Metabolic Reprogramming Through Molecular Imaging” focusses on current achievements, challenges and needs in the application of molecular imaging methods to explore cancer metabolic reprogramming, and evaluate its potential impact on clinical decisions and patient outcome. A series of reviews and perspective articles, along with original research contributions on humans and on preclinical models have been concertedly included in the Topic to build an open forum on perspectives, present needs and future challenges of this cutting-edge research area.

Book The Heterogeneity of Cancer Metabolism

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.

Book Noninvasive Imaging of Cardiac Metabolism

Download or read book Noninvasive Imaging of Cardiac Metabolism written by Ernst E. van der Wall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: F.J.Th. WACKERS Metabolic imaging: The future of cardiovascular nuclear imaging? Since cardiovascular nuclear imaging emerged as a new subspecialty in the mid-1970s, the field has gone through an explosive growth. Radionuclide techniques became readily recognized as important new diagnostic aids in the armamentarium of the clinical cardiologist. Initially, cardiovascular nuclear imaging focused on static myocardial imaging using either thallium-201 or technetium-99m-pyrophosphate for diagnosing acute myocardial infarction. Shortly thereafter, multigated equilibrium radionuclide angiocardiography became the most widely used noninvasive method for assessing cardiac function. Furthermore, attention and clinical application shifted towards the use of radionuclide techniques in conjunction with exercise testing, either with thallium-20 1 myocardial perfusion imaging or technetium-99m left ventricular function studies. The future of cardiovascular nuclear imaging appeared exciting and promising. However, around 1980 pessimists predicted the premature demise of cardiovascular nuclear imaging with the introduction of digital subtraction angiography and nuclear magnetic resonance imaging. These doomsayers have been proven wrong: in 1985 cardiovascular nuclear imaging is thriving and, in many centers, even expanding. Although digital substraction angiography and magnetic resonance imaging provided exquisite anatomic detail, for practical evaluation of patients with ischemic heart disease - in the Coronary Care Unit or exercise laboratory - nuclear techniques appeared to be more practical.

Book Advances in Metabolic Mapping Techniques for Brain Imaging of Behavioral and Learning Functions

Download or read book Advances in Metabolic Mapping Techniques for Brain Imaging of Behavioral and Learning Functions written by Francisco Gonzalez-Lima and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, revolutionary technical advances have permitted neuroscientists to map the functioning of the brain in exquisite detail. Of interest are the new techniques that visually display cell energy metabolism which is coupled to functional brain activity in behaving animals. This is the first book dealing with the application of 2-deoxyglucose and related metabolic mapping techniques for brain imaging of behavioral and learning functions. Quantitative autoradiographic techniques based on the use of exogenous markers include radiolabeled glucose and its analogs, especially 2-deoxyglucose and fluorodeoxyglucose. Other mapping techniques are based on the histochemical staining of endogenous metabolic markers such as cytochrome oxidase, as well as immunohistochemistry for expression of c-fos genes. In spite of the great potential capabilities of the new imaging techniques, relatively few neuroscientists are using this approach to study brain functions related to behavior. There is a need to review state-of-the-art applications of these methods in behavioral neuroscience, and to formulate recommendations for future research in this area. This book is intended to fulfill these needs by bringing together leading neuroscientists using metabolic mapping approaches to elucidate brain mechanisms of behavior. Discussions are not limited to one animal species, but they cover a broad range of vertebrates with unique behavioral capabilities.

Book Optical Imaging of Brain Function and Metabolism 2

Download or read book Optical Imaging of Brain Function and Metabolism 2 written by Arno Villringer and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers the latest developments in optical imaging of the brain which is becoming an increasingly important functional neuroimaging method. Optical intrinsic signals offer unrivaled temporal and spatial resolution of functional measurements of the exposed brain cortex in animals and humans. Near-infrared spectroscopy and imaging ap proaches permit the noninvasive functional assessment of the human brain at bedside. Main advantages of these optical techniques are the biochemical specificity of the meas urements and the potential of measuring correlates of intracellular and intravascular oxy genation simultaneously. Recent data indicate that one may also measure a more direct correlate of neuronal activity associated with changes in light scattering. In this volume, recent technical progress of the optical method is covered as well as the physiological basis of the measurements. In simultaneous studies, near-infrared spec troscopy measurements are directly compared to other functional methods, especially PET and fMRI and examples are given for new applications of the NIRS-method. Based on re sults obtained with optical methods and other functional techniques the latest in our under standing of the coupling of neuronal activity and cerebral blood flow response is reviewed. This is an important basis for a better understanding of all functional neuroi maging methods which rely on neurovascular coupling such as PET, SPET and fMRI. Fi nally the optical method is put into the perspective of presently available functional neuroimaging methods including fMRI, PET, MEG and EEG.
