This book was released on 2023-11-17 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes in diet, environment, and population increase gastrointestinal cancer morbidity. A growing number of novel biomarkers and underlying mechanisms are being elucidated, some of which may even conflict with assumptions of past decades. Therefore, collecting recent findings on novel diagnostic/prognostic factors, biomarkers, and/or risk factors in gastrointestinal cancers is a prerequisite for a better understanding of the disease. Despite remarkable progressions in surgical treatments and chemotherapies, the prognosis of gastrointestinal cancer is far from satisfactory due to the high occurrence of drug resistance. Based on the identification of novel biomarkers as well as their underlying mechanisms, targeted drug development will provide significant complementary therapeutic effects to conventional chemoradiotherapies. High-throughput methods such as next-generation sequencing on RNA level and mass spectrometry on protein/lipid/metabolite level serve as efficient strategies for biomarker identification and drug development. This Research Topic aims at presenting recent advances on gastrointestinal cancer biomarkers and their underlying functional mechanisms, providing a better understanding of carcinogenesis, tumor progression, tumor relapse, as well as drug resistance. This will subsequently contribute to the development of novel therapeutic interventions targeting gastrointestinal cancers, thus improving patients' outcomes.

Download or read book Gastrointestinal Cancer Immunotherapy from Drug Resistance Mechanisms to Overcoming Strategies written by Xiaofang Che and published by Frontiers Media SA. This book was released on 2023-06-15 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gastrointestinal (GI) cancers, including gastric cancer, colon cancer, liver cancer, esophageal cancer, and pancreatic cancer, seriously threaten the health of human beings worldwide with a high rate of morbidity and mortality. The clinical successes achieved with immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 and CTLA-4 have opened a new cancer therapy era and brought new hope to cancer patients. However, the overall response rate (ORR) of ICI monotherapy in the non-selective population is only about 20%, in which some patients subsequently develop immunotherapy resistance. Moreover, the remaining 70-80% of patients displayed primary resistance to ICIs, and a few patients even experienced hyper progression disease (HPD). Although PD-L1 expression, mismatch repair deficient (MMRd), high tumor mutational burden (TMB-H) , high homologous recombination deficiency (HRD), and tumor infiltrated immune cells (TILs) are known as effective biomarkers for immunotherapy, growing studies have reported that ICIs could not improve the OS of all patients with PD-L1 expression higher than 50%, and the ORR of MSI-H patients was only about 60%, whereas some patients with low PD-L1 expression or MSS could still benefit from immunotherapy, indicating the complexity of ICI resistance. Therefore, it is of great importance and significance to explore the prediction biomarkers for primary or acquired immunotherapy resistance and elucidate their underlying molecular mechanisms and develop reversal strategies. Due to the multiple steps of the cancer immune cycle and complex immune microenvironment, any disorders of immune cell infiltration or T cell activation, such as lack of antigens and/or their presentation, lack of response to antigen presentation, and T cell priming, could contribute to ICI resistance. The combination with anti-angiogenesis therapy, radiotherapy, chemotherapy, and other ICIs has improved the efficacy of ICI therapy to some extent in the clinic. Although numerous studies related to ICI resistance were reported in GI cancers, due to the strong spatial/temporal heterogeneity and the complex immune microenvironment in different kinds of GI cancers and different individuals, many questions about ICI resistance and reversal strategies remain unsolved. The aim of this Research Topic is to provide a forum to exhibit the latest research achievement related to the exploration of biomarkers for immunotherapy resistance including HPD and the underlying molecular mechanisms, as well as the development of reversal strategies in GI cancers. We hope this Research Topic will lead to a better understanding of precision cancer immunotherapy and provide useful clues for clinical application to benefit more GI cancer patients with immunotherapy.

Download or read book The Role of non coding RNAs in Gastrointestinal Cancers written by Kanjoormana Aryan Manu and published by Frontiers Media SA. This book was released on 2024-03-08 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gastrointestinal malignancies encompass a large number of tumor types, and collectively are responsible for a significant portion of new cancer cases annually. According to the IARC database, colorectal cancer alone is responsible for approximately 10% of new cases of cancer worldwide annually. There is significant heterogeneity across the various tumor types, with different pathways and factors involved in oncogenesis, as well as varying degrees of prognosis depending on the tumor type. Non-coding RNAs (ncRNAs) contribute to a significant portion of the human transcriptome, and of particular interest are the micro-RNAs (miRNAs), long ncRNAs (lncRNAs), and circular ncRNAs (circRNAs). With the advent of next-generation sequencing and new technologies such a minimally invasive biopsy techniques, there is a growing body of evidence elucidating the role of ncRNAs in the progression of various form of gastrointestinal cancers. Furthermore, in addition to their relevance to cancer progression, these ncRNAs have important potential as biomarkers and prognostic markers for various GI cancers.

Download or read book Noncoding RNA in Disease Diagnosis Etiology Progression Prognosis and Treatment written by Sujit Nair and published by Frontiers Media SA. This book was released on 2024-01-10 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exciting class of regulatory small noncoding RNAs (ncRNAs) has emerged in recent years that play key role(s) in the etiology/pathogenesis and diagnosis/prognosis of various human diseases including various hematologic and solid cancers, cardiovascular diseases including stroke/atherosclerosis, diabetes, obesity, and metabolic disorders, neuropathies, neurodegeneration including Alzheimer’s Disease, Parkinson’s Disease or Multiple Sclerosis, neurological disorders including epilepsy and muscular dystrophies, liver diseases, pulmonary fibrosis, immune-mediated inflammatory disorders and inflammatory bowel disease, gastritis, autoimmune disorders including arthritis, acromegaly, chronic kidney disease, allergic rhinitis, vitiligo, osteoporosis, obstructive sleep apnea, ocular disease, periodontitis, skeletal muscle atrophy, and parasitic diseases including leishmaniasis, amongst others. These ncRNAs include primarily microRNAs (miRNAs), long noncoding RNAs (lncRNAs), circular RNAs (circRNAs), piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs), small interfering RNAs (siRNAs) or exosomal RNAs (exRNAs), etc. that modulate the expression of target genes thus potentially regulating protein expression in normal versus diseased individuals. This Research Topic recognizes the importance of and seeks to explore, ncRNAs in the diagnosis, etiology, progression, prognosis, and treatment of human disease as well as novel biomarker discovery by multi-omics technologies and other methodologies. Indeed, high-throughput technologies employing deep sequencing, proteogenomic, microarrays, and quantitative real-time PCR have begun to shed new light on the architecture of ncRNA landscapes in various diseases and key signal transduction cascades modulated by these ncRNAs in disease pathology. Epigenetic control of gene expression mediated via miRNAs, for instance, has expanded our understanding of transcriptional and post-transcriptional regulation of gene expression by critical ncRNAs in the cellular milieu. Network biology approaches including the construction of relevant ncRNA networks, ncRNA-mRNA networks, and bioinformatics for mining of ncRNAs, are gaining greater relevance in the search for ‘target hubs’ or novel biomarker(s) of disease. Delineation of ncRNA signatures by transcriptomic profiling or RNA-seq, for example, is an important milestone in furthering our knowledge of the repertoire of specific ncRNAs implicated in various diseases. Further, elucidation of the specific steps of the signaling cascades where ncRNAs exert their regulatory actions will augment our understanding of diseases. This will lead to the development of (i) a novel biomarker, or biomarker signature panel, for disease; (ii) ncRNA-based companion diagnostics for diagnosis of disease; (iii) point-of-care testing devices based on ncRNAs; (iv) newer therapeutic agents that target novel biomarkers with specificity, thereby reducing toxicity; (v) ncRNA-based prophylactic approaches of the future; and, (vi) ncRNA-based prognosis of disease.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Colon Cancer Diagnosis and Therapy written by Ganji Purnachandra Nagaraju and published by Springer Nature. This book was released on 2021-06-10 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colorectal cancer (CRC) is a major global health challenge as the third leading cause for cancer related mortalities worldwide. Despite advances in therapeutic strategies, the five-year survival rate for CRC patients has remained the same over time due to the fact that patients are often diagnosed in advanced metastatic stages. Drug resistance is another common reason for poor prognosis. Researchers are now developing advanced therapeutic strategies such as immunotherapy, targeted therapy, and combination nanotechnology for drug delivery. In addition, the identification of new biomarkers will potentiate early stage diagnosis. This book is the first of three volumes on recent developments in colorectal diagnosis and therapy. Each volume can be read on its own, or together. Each volume focuses on different novel therapeutic advances, biomarkers, and identifies therapeutic targets for treatment. Written by leading international experts in the field, coverage also addresses the role of diet habits and lifestyle in reducing gastrointestinal disorders and incidence of CRC. Chapters discuss current and future diagnostic and therapeutic options for colorectal cancer patients, focusing on immunotherapeutic, nanomedicine, biomarkers, and dietary factors for the effective management of colon cancer.
