Book Description
Stem cells provide for life-long cell replacement in tissues and organs, and have inherent homing abilities that are critical in therapeutic applications. Stem cells are also the driving force of cancer where genetic/epigenetic alterations culminate in tumorigenesis either in tissue stem cells or in some of their derivatives. As a rare subset of the tumor, cancer stem cells are the only drive of tumor initiation/propagation. Autologous and cancer stem cells are thus the key targets of 1) long-term and transient-regenerative/epigenetic gene therapy and 2) of recurrence-free anticancer therapy, respectively. While cancer stem cell gene therapy still needs time to accomplish, autologous stem cells have been instrumental in the first unequivocal successes for gene therapy whereby ex vivo retrovirally corrected hematopoietic stem cells have been returned to the patients.This timely book presents 1) the aforementioned stem cell gene therapy achievements that rely on random-integration of therapeutic transgenes into host chromosomes and 2) emerging experimental approaches aimed at eliminating random-integration oncogenic hazards through site-specific integration or gene targeting. Breakthrough endonuclease-boosted gene targeting for gene correction (inherited diseases) or targeted integration of therapeutic transgenes (other disorders) culminating in an efficiency compatible with clinical trials is one of the highlights of the book. Highlights also include the pioneering transplantation of adult pluripotent stem cells as a substitute for tissue-specific stem cells, thereby pinpointing the invaluable potential for stem cell gene therapy applications of autologous cells able to contribute to all three germ layers. Stem cell gene therapy is thus discussed in terms of 1) magnifying stem cell therapeutic homing through transient regenerative gene therapy and 2) of tackling most pathologies (including mitochondrial DNA diseases and ageing disorders) through stem cell repopulation dynamics into appropriate niches (long-term engraftment) and tissues (cell turn-over). Regarding cancer stem cell gene therapy, focus is on both the increasing number of identified tissue-specific cancer stem cells as the ultimate therapeutic targets and on the development of armed stem cells as tumor-homing vectors for targeted anticancer therapy.

Book Description
Studies have shown that alterations of epigenetics and microRNAs (miRNAs) play critical roles in the initiation and progression of human cancer. Epigenetic silencing of tumor suppressor genes in cancer cells is generally mediated by DNA hypermethylation of CpG island promoter and histone modification such as methylation of histone H3 lysine 9 (H3K9) and tri-methylation of H3K27. MiRNAs are small non-coding RNAs that regulate expression of various target genes. Specific miRNAs are aberrantly expressed and play roles as tumor suppressors or oncogenes during carcinogenesis. Important tumor suppressor miRNAs are silenced by epigenetic alterations, resulting in activation of target oncogenes in human malignancies. Stem cells have the ability to perpetuate themselves through self-renewal and to generate mature cells of various tissues through differentiation. Accumulating evidence suggests that a subpopulation of cancer cells with distinct stem-like properties is responsible for tumor initiation, invasive growth, and metastasis formation, which is defined as cancer stem cells. Cancer stem cells are considered to be resistant to conventional chemotherapy and radiation therapy, suggesting that these cells are important targets of cancer therapy. DNA methylation, histone modification and miRNAs may be deeply involved in stem-like properties in cancer cells. Restoring the expression of tumor suppressor genes and miRNAs by chromatin modifying drugs may be a promising therapeutic approach for cancer stem cells. In this Research Topic, we discuss about alterations of epigenetics and miRNAs in cancer and cancer stem cell and understand the molecular mechanism underlying the formation of cancer stem cell, which may provide a novel insight for treatment of refractory cancer.

Book Description
Stem Cell Epigenetics, Volume 16, examines how epigenetics are involved in stem cell differentiation, how a stem cell rapidly transitions into a molecularly distinct cell type, and how this process may be reversed or managed via epigenetic reprogramming. Topics discussed include chromatin in pluripotency, epigenetic regulation of reprogramming, stem cells and DNA methylation, histone modifications in stem cells and differentiation, higher-order chromatin conformation in pluripotent cells, epigenetics and disease modeling, organoids from pluripotent cells, transcriptional regulation in stem cells and differentiation, non-coding RNAs in pluripotency and early differentiation, and diseases caused by epigenetic alterations in stem cells. Additionally, the potential implementation of stem cell epigenetics in drug discovery, regenerative medicine, and disease treatment is discussed in detail, helping researchers and physicians bring this exciting and fast evolving field to the clinic. Provides genetic researchers, students and physicians with evidence indicating the epigenetic mechanisms involved in stem cell differentiation Highlights the specific characteristics of the epigenetic modifications and misregulations that may result in disease pathogenesis Examines the potential application of stem cell epigenetics towards developing therapeutic interventions for disease and advancing regenerative medicine Features chapter contributions by leading international experts

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.

Book Description
Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
