Book Description
Genetic aberrations and epigenetic modifications are critical drivers of cancer progression and metastasis. Although recurrent mutations in primary and metastatic cancers have been shown to be concordant, there are several metastasis-associated mutations responsible for resistance to specific therapies that are frequently located in genes that regulate DNA methylation and chromatin modifications. Recent studies have shown that distinct subgroups of poor-prognosis tumors lack genetic alterations but are epigenetically regulated, pointing to the critical role of epigenetic modifications in cancer progression. This Special Issue provides novel insights into the mechanisms underlying processes associated with cancer cell plasticity and the development of metastatic disease.

Book Description
Overall, this book illustrates the complexities of the regulation and deregulation of genes mediated through epigenetics in the development and progression of human malignancies. All the articles have been carefully chosen to represent several cancer systems with state of our knowledge on the role of epigenetic deregulation of microRNAs (miRNAs) and their target mRNAs along with epigenetic deregulation of mRNAs. This book also illustrates the role of several dietary agents, collectively called nutraceuticals or natural agents in modulating the epigenetic reprogramming of miRNAs and mRNAs for the prevention and/or treatment of human malignancies. It is well known that genetic aberrations, especially inherited through parents (somatic genetic alterations) contribute to the development of less than 10% of all cancer yet epigenetic alterations in genes especially through selective methylation and acetylation appears to be responsible for the development and progression of the vast majority of all cancers. Therefore, understanding the role of epigenetics in the regulation of genes especially through deregulated expression of miRNAs as presented in this book will allow scientists to devise targeted therapeutic strategies for re-expression of the lost genes or down-regulate the genes that are over-expressed in order to eradicate cancer. It is hoped that targeting epigenetics will not only target cancer cells but it will also target the tumor microenvironment (more like the entire tumor environment such as the entire host) for achieving better treatment outcomes for patients diagnosed with cancer which will lead to achieve the long-term objective for complete eradication of cancer. This book contains fifteen chapters which begins with the concept of systems and network biology for investigating the epigenetics of cancer followed by a series of articles on the role of miRNAs and their target genes in the biology of pancreatic cancer and other cancers such as breast, kidney, prostate and and colon. Since it is becoming increasingly clear that cancer stem cells (CSCs) are important in the development and progression of cancer, and CSCs are important in therapeutic resistance, treatment failure and tumor recurrence, thus the importance of CSCs and epigenetics has been highlighted by a very timely article on epigenetic variations of stem cell markers in cancer including miRNAs. Moreover, just targeting heterogeneous cancer cell populations may not be optimal to eradicate tumors and for which one must take a holistic approach for developing drugs that could also target the tumor microenvironment and tumor dormancy that are regulated through epigenetics. Keeping abreast with this thought process the concluding chapter provides a concept towards curative cancer therapy with maspin, which could be a unique window of opportunity to target tumor dormancy. Therefore, it suggest that targeting the tumor dormancy and the tumor microenvironment using novel therapeutics specifically by targeting epigenetics would become the future of medicine.

Book Description
In recent years, the field of epigenetics has grown significantly, driving new understanding of human developmental processes and disease expression, as well as advances in diagnostics and therapeutics. As the field of epigenetics continues to grow, methods and technologies have multiplied, resulting in a wide range of approaches and tools researchers might employ. Epigenetics Methods offers comprehensive instruction in methods, protocols, and experimental approaches applied in field of epigenetics. Here, across thirty-five chapters, specialists offer step-by-step overviews of methods used to study various epigenetic mechanisms, as employed in basic and translational research. Leading the reader from fundamental to more advanced methods, the book begins with thorough instruction in DNA methylation techniques and gene or locus-specific methylation analyses, followed by histone modification methods, chromatin evaluation, enzyme analyses of histone methylation, and studies of non-coding RNAs as epigenetic modulators. Recently developed techniques and technologies discussed include single-cell epigenomics, epigenetic editing, computational epigenetics, systems biology epigenetic methods, and forensic epigenetic approaches. Epigenetics methods currently in-development, and their implication for future research, are also considered in-depth. In addition, as with the wider life sciences, reproducibility across experiments, labs, and subdisciplines is a growing issue for epigenetics researchers. This volume provides consensus-driven methods instruction and overviews. Tollefsbol and contributing authors survey the range of existing methods; identify best practices, common themes, and challenges; and bring unity of approach to a diverse and ever-evolving field. Includes contributions by leading international investigators involved in epigenetic research and clinical and therapeutic application Integrates technology and translation with fundamental chapters on epigenetics methods, as well as chapters on more novel and advanced epigenetics methods Written at verbal and technical levels that can be understood by scientists and students alike Includes chapters on state-of-the-art techniques such as single-cell epigenomics, use of CRISPR/Cas9 for epigenetic editing, and epigenetics methods applied to forensics

Book Description
Breast cancer is the most common malignancy and a major cause of cancer-related death among Canadian women. Although treatment of primary breast tumours is highly successful through surgery, metastatic breast cancer is difficult to treat. Cancer progression and metastasis require the accumulation of numerous genetic and epigenetic alterations. Normal cells that acquire such alterations can transform into cancer cells, resulting in primary tumour formation. Primary tumours are a heterogeneous population, containing cells of various metastatic potentials. Cells that acquire a high potential for metastasis can spread to secondary locations. Our model system consists of two subpopulations, with different metastatic potential, derived from the same rat mammary adenocarcinoma. Using this model, a differentially expressed novel gene, termed MS-1, was discovered. Due to significant expression of this gene in the poorly metastatic subpopulation and lack of expression in the highly metastatic subpopulation, MS-1 may have involvement in metastasis suppression. Several breast cancer metastasis suppressor genes have been identified on the basis that they are down-regulated during the progression of metastasis. Epigenetic mechanisms, such as DNA methylation, account for loss of expression in several of these genes. Hypermethylation of CpG islands within gene promoters results in deacetylation of histone proteins and produces a compact chromatin structure that is unfavourable for transcription. A CpG island spans the 5 untranslated region, exon 1 and part of intron 1 of the MS-1 gene. Our data reveals aberrant methylation patterns of this CpG island in our model. Also, MS-1 expression appears to be partially induced by both DNA methylation and histone deacetylation inhibitors. Following a screen of several cancer cell lines of various metastatic potential, it appears that the presence of DNA methylation in the CpG island of MS-1 correlates with the lack of MS-1 expression.
