Book Description
One-carbon metabolism, a network of enzymatic reactions involving the transfer of methyl groups, depends on B-vitamins as cofactors, folate as a methyl group carrier, and amino acids, betaine, and choline as methyl group donors. One-carbon metabolism influences many processes in cancer initiation and development such as DNA synthesis, genome stability, and histone and epigenetic methylation. To study markers of one-carbon metabolism and inflammation in relation to colorectal cancer (CRC) risk, we used prediagnostic plasma samples from over 600 case participants and 1200 matched control participants in the population-based Northern Sweden Health and Disease Study cohort. This thesis studies CRC risk with respect to the following metabolites measured in pre-diagnostic plasma samples: 1) folate, vitamin B12, and homocysteine; 2) components of one-carbon metabolism (choline, betaine, dimethylglycine, sarcosine, and methionine); and 3) three markers of different aspects of vitamin B6 status. In addition, this thesis examines three homocysteine ratios as determinants of total B-vitamin status and their relation to CRC risk. In two previous studies, we observed an association between low plasma concentrations of folate and a lower CRC risk, but we found no significant association between plasma concentrations of homocysteine and vitamin B12 with CRC risk. We have replicated these results in a study with a larger sample size and found that low folate can inhibit the growth of established pre-cancerous lesions. Using the full study cohort of over 1800 participants, we found inverse associations between plasma concentrations of the methionine cycle metabolites betaine and methionine and CRC risk. This risk was especially low for participants with the combination of low folate and high methionine versus the combination of low folate and low methionine. Well-functioning methionine cycle lowers risk, while impaired DNA synthesis partly explains the previous results for folate. We used the full study cohort to study associations between CRC risk and the most common marker of vitamin B6 status, pyridoxal' 5-phosphate (PLP), and two metabolite ratios, PAr (4-pyridoxic acid/(PLP + pyridoxal)) estimating vitamin B6 related inflammatory processes and the functional vitamin B6 marker 3-hydroxykynurenine to xanthurenic acid (HK:XA). Increased vitamin B6-related inflammation and vitamin B6 deficiency increase CRC risk. Inflammation was not observed to initiate tumorigenesis. Total B-vitamin status can be estimated by three different recently introduced homocysteine ratios. We used the full study cohort to relate the ratios as determinants of the total B-vitamin score in case and control participants and estimated the CRC risk for each marker. Sufficient B-vitamin status as estimated with homocysteine ratios was associated with a lower CRC risk. These studies provide a deeper biochemical knowledge of the complexities inherent in the relationship between one-carbon metabolism and colorectal tumorigenesis.

Book Description
ABSTRACT It has been widely recognized that microRNAs are involved in nearly all cellular processes that have been investigated and contribute to a variety of diseases including cancer. Our prior studies demonstrated the depletion of one-carbon metabolism related B-vitamins, including folate, vitamin B2, B6 and B12, induced a genomic DNA hypomethylation and an elevation of the tumorigenic Wnt signaling in mouse colonic epithelium. The present study aimed to define whether microRNAs serve as mediators between these B-vitamins and the Wnt signaling, and thereby influence intestinal tumorigenesis. MicroRNA expression profiles were measured using miRNA microarray and real-time PCR on colonic epithelial cells from Apc1638N mice fed with diets deplete or sufficient in those B-vitamins. In silico bioinformatic analysis were performed to predict microRNA gene targets within the Wnt signaling cascade. Out of 609 microRNA examined, 18 microRNAs were found to be either significantly (p

Book Description
Molecular Basis of Nutrition and Aging: A Volume in the Molecular Nutrition Series focuses on the nutritional issues associated with aging and the important metabolic consequences of diet, nutrition, and health. The book is subdivided into four parts that reflect the impact of nutrition from a biomolecular level to individual health. In Part One, chapters explore the general aspects of aging, aging phenotypes, and relevant aspects of nutrition related to the elderly and healthy aging. Part Two includes molecular and cellular targets of nutrition in aging, with chapters exploring lipid peroxidation, inflammaging, anabolic and catabolic signaling, epigenetics, DNA damage and repair, redox homeostasis, and insulin sensitivity, among others. Part Three looks at system-level and organ targets of nutrition in aging, including a variety of tissues, systems, and diseases, such as immune function, the cardiovascular system, the brain and dementia, muscle, bone, lung, and many others. Finally, Part Four focuses on the health effects of specific dietary compounds and dietary interventions in aging, including vitamin D, retinol, curcumin, folate, iron, potassium, calcium, magnesium, zinc, copper, selenium, iodine, vitamin B, fish oil, vitamin E, resveratrol, polyphenols, vegetables, and fruit, as well as the current nutritional recommendations. Offers updated information and a perspectives on important future developments to different professionals involved in the basic and clinical research on all major nutritional aspects of aging Explores how nutritional factors are involved in the pathogenesis of aging across body systems Investigates the molecular and genetic basis of aging and cellular senescence through the lens of the rapidly evolving field of molecular nutrition

Book Description
As the field of nutritional neuroscience has grown, both the scientific community and the general population have expressed a heightened interest in the effect of nutrients on behavior. Diet, Brain, Behavior: Practical Implications presents the work of a diverse group of scientists who collectively explore the broad scope of research in the field. The subject matter of each chapter in this volume was chosen to ensure the current or potential for further applicability to practical, applied issues. Topics discussed include: Concepts of mental energy and fatigue The dangers of obesity and its effect on behavior Exercise, dietary restriction, and supplements for weight loss The effects of caffeine, creatine, theanine, B vitamins, and other dietary supplements on brain functioning and behavior The reward deficiency hypothesis and eating disorders The importance of maintaining proper fluid intake The effects of eating breakfast on performance The role of diet in pain sensitivity During the past decade, there has been an explosion in research and publications in this field. This collection of contributions represents the cutting edge of current research and new advancements in this area. The book provides essential information to those working in a diverse range of fields, including nutrition, neuroscience, psychology, and exercise physiology as well as medicine, dietetics, and occupational therapy.
