Book Description
Pancreatic Cancer has been and still is one of the deadliest types of human malignancies. The annual mortality rates almost equal incidence rates making this disease virtually universally fatal. The 5-year survival of patients with pancreatic cancer is a dismal 5% or less. Therapeutic strategies are extremely limited with gemcitabine extending the survival by a disappointing few weeks. The failure of several randomized clinical trials in the past decade investigating the therapeutic efficacy of different mono- and combination therapies reflects our limited knowledge of pancreatic cancer biology. In addition, biomarkers for early detection are sorely missing. Several pancreatic cancer risk factors have been identified. Unfortunately, the underlying mechanisms linking these risk factors to cancer development are poorly understood. Well known possible and probable risk factors for the development of pancreatic cancer are age, smoking, chronic pancreatitis, obesity, and type-2 diabetes mellitus. Age is certainly of the most important risk factors as most cases of pancreatic cancer occur in the elderly population. Smoking ten cigarettes a day increases the risk by 2.6 times and smoking a pack per day increases it by 5 folds. Chronic pancreatitis increases the risk of pancreatic cancer by up to 13 times. Patients with hereditary forms of chronic pancreatitis have an even higher risk. Obesity, a growing global health problem, increases the risk of pancreatic cancer by about 1.5 fold. Type-2 diabetes mellitus is also associated with an increased risk of pancreatic cancer by at least two-fold. The more recent the onset of diabetes, the stronger the correlation with pancreatic cancer is. In addition, heavy alcohol drinking, a family history of the disease, male gender and African American ethnicity are other risk factors for pancreatic cancer. Pancreatic cancer is characterized by several genetic alterations including mutations in the Kras proto-oncogene and mutations in the tumor suppressor genes p53 and p16. While Kras mutations are currently thought as early events present in a certain percentage of pancreatic intraepithelial neoplasias (PanINs), known precursor lesions of pancreatic ductal adenocarcinomas, mutations in tumor suppressor genes, e.g. p53, seem to accumulate later during progression. In addition, several intracellular signaling pathways are amplified or enhanced, including the MAPK/ERK and PI3K/AKT signaling modules. Overall, these genetic alterations lead to enhanced and sustained proliferation, resistance to cell death, invasive and metastatic potential, and angiogenesis, all hallmarks of cancers. The scope of this Research Topic is to collect data and knowledge of how risk factors increase the risk of initiation/progression of pancreatic cancer. Of particular interest are potential underlying molecular mechanisms. Understanding the molecular mechanisms and driving signaling pathways will ultimately allow the development of targeted interventions to disrupt the risk factor-induced cancer development. This Research Topic is interested in a broad range of risk factors, including genetic and environmental, and welcomes original papers, mini and full reviews, and hypothesis papers. Manuscripts that address the effect of combination of risk factors on pancreatic cancer development and progression are of great interest as well.

Book Description
This book comprehensively describes the association between metabolic syndrome and pancreatic cancer progression, and the mechanism of action and target definition with a view to drug discovery. Metabolic syndrome, which includes adnominal obesity, hypertension, dyslipidemia, and hyperglycemia, has recently been shown to play an important role in the etiology and progression of various cancers. Further, obesity and diabetes have been associated with an increased incidence of gastric cancers. The book reviews the key biological mechanisms underlying the association between metabolic dysregulation, including obesity-associated enhancement of growth factor signaling, inflammation, and perturbation in pancreatic cancer cell growth and metastasis. It also illustrates the role of the inflammatory signaling pathway in metabolic diseases as well as tumor growth and explores the potential of these pathways as the rational targets for pancreatic cancer therapy. Lastly, the book offers a comprehensive description of the challenges associated with diabetes and pancreatic cancer therapy.

Book Description
Oncogenes are mutated and/or overexpressed at high levels in tumor cells. Tumors of the lung, breast, pancreas, and colon may display specific oncogenetic features. These tumors have been largely associated with exposure to environmental carcinogens and a variety of biological agents, including viruses. These carcinogens can induce specific genetic and epigenetic alterations in these tissues, leading to aberrant functioning of oncogenes and tumor suppressor genes. On the microRNAs (miRNAs) there are significant modifiers of both transcription and translation of oncogenes in carcinogenesis. In the last 50 years, several oncogenes and microRNAs related to these oncogenes have been identified in different types of human cancers. It is now clear that high expression of oncogenes, DNA damage response, and regulation of the cell cycle are related to the circadian clock. This book will mainly focus on the expressions of different oncogenes in breast, colon, and lung cancers. Moreover, readers will gain qualified scientific knowledge of the alterations in miRNAs in different types of cancers and the effects of the circadian clock on the expression of oncogenes in carcinogenesis.

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
This book illustrates the importance of transcription factors in gastrointestinal cancer progression and metastasis with regard to understanding the mechanism and target definition in drug discovery. Further, it describes the complex issues associated with cancer cell growth and metastasis. The respective chapters provide detailed information on the various types of transcription factors (NF-kB, HIF-1, STAT-3, E2F1, and Sp1) and gastric-associated cancers (esophagus, stomach, colorectal, liver and pancreatic cancers) in connection with specific functional studies like cell cycle, angiogenesis, migration, invasion and apoptosis. These transcription factors control the expression of several signaling pathways involved in tumor growth, making them ideal targets for gastrointestinal cancer therapy. In closing, the book provides comprehensive descriptions of the major challenges associated with gastrointestinal cancer therapy.

Book Description
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.
