Mitochondrial DNA Mutations in Aging, Disease and Cancer by Keshav K. Singh Pdf

Many human genetic diseases associated with blood, brain, colon, ear, eye, heart, kidney, liver, muscle, and pancreas are caused by mutations in mitochondrial DNA. Mutations in DNA can result in defects of the electron transport complexes, intermediates of the tricarboxylic acid cycle and substrate transport. The clinical manifestation of these diseases often involves muscle and the nervous system. Mitochondrial DNA mutations have now been associated with aging as well as age-related degenerative diseases such as Parkinson's, Alzheimer's, and Huntington's diseases. Changes in structure, function, and a number of mitochondria play an important role in carcinogenesis. Furthermore, the role of mitochondria in the execution of programmed cell death or apoptosis has been recognized recently.

Mitochondrial DNA and Diseases by Hongzhi Sun,Xiangdong Wang Pdf

The book describes molecular principles and mechanisms by which mitochondrial DNA (mtDNA) can drive the occurrence of diseases and the latest understanding of mtDNA biology. The book explores roles of mtDNA mutation and genetic changes in cancer, with a special focus on lung cancer, and the significance of approach, application, and bioethics of mtDNA sequencing. Authors made a great effort to overview roles of mtDNA signaling pathways, base excision repair, methylation, USP30-mediated regulation, mitochondrial ribosome, autophagy pathways, or ROS-dependent signaling in the pathogenesis, diagnosis, prevention and treatment of diseases. It also demonstrates the importance of basic mitochondrial genetics and the relationship between mutations and disease phenotypes and ageing. This book covers not only the basic information of mtDNA, the relationship of mtDNA and disease, but also mtDNA in stem cell and mitochondria and metabolism etc. The book is written for biological and clinical students and researchers in the field of mtDNA–associated diseases.

Aging and Age-Related Disorders by Stephen Bondy,Kenneth Maiese Pdf

Features that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system. The incidence of some disorders such as Alzheimer's disease and vascular diseases are sufficiently prevalent in the extreme elderly that these disorders can arguably be considered "normal". Aging and Aging-Related Disorders examines the interface between normal and pathological aging, and illustrates how this border can sometimes be diffuse. It explores and illustrates the processes underlying the means by which aging becomes increasingly associated with inappropriate levels of free radical activity and how this can serve as a platform for the progression of age-related diseases. The book provides chapters that examine the interactive relationship between systems in the body that can enhance or sometimes even limit cellular longevity. In addition, specific redox mechanisms in cells are discussed. Another important aspect for aging discussed here is the close relationship between the systems of the body and exposure to environmental influences of oxidative stress that can affect both cellular senescence and a cell’s nuclear DNA. What may be even more interesting to note is that these external stressors are not simply confined to illnesses usually associated with aging, but can be evident in maturing and young individuals. A broad range of internationally recognized experts have contributed to this book. Their aim is to successfully highlight emerging knowledge and therapy for the understanding of the basis and development of aging–related disorders.

Mitochondrial Dysfunction in Aging and Diseases of Aging by Richard H. Haas Pdf

This collection of review articles authored by international experts pulls together current information about the role of mitochondria in aging and diseases of aging. Mitochondria are vitally important cellular organelles and undergo their own aging process becoming less efficient in aged animals including humans. These changes have wide-ranging significance contributing to immune dysfunction (autoimmunity and immune deficiency), inflammation, delayed healing, skin and retinal damage, cancer and most of the degenerative diseases of aging. Mitochondrial aging predisposes to drug toxicity in the geriatric population and to many of the features of normal aging. The research detailed in this book summarizes current understanding of the role of mitochondria in the complex molecular changes of aging, moving on to specific diseases of aging. Mitochondrial dysfunction is an important target for development of treatments for aging and disease. The last article details how exercise is a treatment and combats many features of the aging process.

Investigation of human mitochondrial DNA abnormality in colon cancer by Mansoureh Akouchekian Pdf

The appearance of mtDNA abnormalities including deletions, duplications, insertions or combinations of them in colorectal cancer (CRC) patients was investigated in this work. Our result showed that 11 of 90 CRC patients had a 8.7 kb mtDNA deletion (12.2%) while this deletion was not found in 33 healthy controls. (P=0.035) We conclude that the 8.7 kb deletion can be a secondary effect of the cancer process, which is not inherited. This is the first report on large scale deletions in CRC. We also analyzed the correlation between cancers and mitochondrial haplogroups. The relationship between CRC and each of 9 major mitochondrial haplogroups were examined in Iranian CRC patients. This is the first study to trace mtDNA HVSI variants in CRC patients of the Persian population. Our data showed that patients with CRC have a significantly (P=0.001) higher frequency of haplogroup K (9.5%) when compared with controls (0%). The mitochondrial polymorphisms in haplogroup K might play a causative role in predisposing to CRC. Variations in the D-loop region were found in both CRC patients and healthy people but the frequency of SNPs in CRC patients was higher than in control samples. We found 13 new polymorphisms that had not been recorded in the mitochondrial database. We also detected one T→C transition at np16519 in 28 out of 40 patients (70%). In a recent study researchers reported that the T16519C variation worsen the outcome of pancreatic cancer patients, possibly because it is involved in altering cellular metabolism. Because we found this mutation frequently in our healthy controls (43%) and could not find any differentiation among our patients with respect to the alleles at this mutation, we conclude that the functional significance of this mutation needs further investigation. We also analyzed somatic mutations in mitochondrial genes encoding subunits of the respiratory complex I. Seven somatic mutations in the MT-ND1 gene were found. Six of these mutations were synonymous mutations. The T4216C mutation that was detected in 26% of the CRC tested samples resulted in the substitution of tyrosine with the amino acid histidine at amino acid position 304. The T4216C mutation was recently reported in LHON patients (Povalko et al., 2005). The patients in our study who carried the T4216C mutation had no known vision problems. It is difficult to speculate about the role of this mutation in CRC. LHON mutations were shown to affect complex I in mitochondria and other investigators found other mutations in different parts of this gene. To show pathogenicity of this mutation or find its role in cancer, more investigations particularly in mtDNA of LHON patients are needed. Because cancer is a multifactorial disease and a causative mutation which leads to blindness and cancer has not been reported, we conclude that this mutation may be a secondary effect or rare polymorphism.

Mitochondrial Genetics and Cancer by Gabriel D. Dakubo Pdf

With very few exceptions, eukaryotic cells possess two interdependent genomes, chromosomal and extra-chromosomal. Over the past several decades, cancer - search has focused primarily on deciphering the intricate alterations in the chro- somal genome, with until recently, very little attention to its cytoplasmic counterpart. In spite of the enormous complexity of the nuclear genome, which we now fully appreciate after completion of the human genome project, the efforts of cancer researchers are commendable in terms of the tremendous gains made in unraveling the numerous genetic changes in cancer. These changes include d- coveries of tumor suppressor genes, oncogenes, and caretaker genes that are often mutated in cancer. Recent studies of genomic pro?les are uncovering even more altered and mutated genes in cancer. Besides these ?ndings, several therapeutic targets for chemotherapy are currently made from studies of altered nuclear genetic pathways. Inspite of all these positive efforts, the war on cancer, declared in 1971 by Richard Nixon, is far from being worn. Indeed, the failure of chemotherapy is obvious to clinicians, oncologists, and their patients alike. Moreover, the global incidence and prevalence of cancer continue to rise. What are we missing? Which direction should we be taking? Of course, modern integrated nuclear genomics, proteomics, and metabolomics should provide important clues to carcinogenesis, but the contribution of cytoplasmic genetic alterations to carcinogenesis cannot be neglected.

Cancer as a Metabolic Disease by Thomas Seyfried Pdf

The book addresses controversies related to the origins of cancer and provides solutions to cancer management and prevention. It expands upon Otto Warburg's well-known theory that all cancer is a disease of energy metabolism. However, Warburg did not link his theory to the "hallmarks of cancer" and thus his theory was discredited. This book aims to provide evidence, through case studies, that cancer is primarily a metabolic disease requring metabolic solutions for its management and prevention. Support for this position is derived from critical assessment of current cancer theories. Brain cancer case studies are presented as a proof of principle for metabolic solutions to disease management, but similarities are drawn to other types of cancer, including breast and colon, due to the same cellular mutations that they demonstrate.
