The link between genome instability and adverse health outcomes during the various stages of life, such as infertility, fetal development and cancer, is briefly reviewed against a background of evidence indicating that genome instability, in the absence of overt exposure to genotoxins, is itself a sensitive marker of nutritional deficiency. The latter is illustrated with cross-sectional and dietary intervention data obtained using the micronucleus assay, an efficient biomarker for diagnosing genome instability and nutritional deficiency. The concept of recommended dietary allowances for genome stability and how this could be achieved is discussed together with the emerging field of nutritional genomics for genome stability. The review concludes with a vision for a disease-prevention strategy based on the diagnosis and nutritional treatment of genome instability, i.e. 'Genome Health Clinics'.
在有证据表明基因组不稳定在未明显暴露于基因毒素的情况下本身就是营养缺乏的敏感标志物这一背景下,简要回顾了基因组不稳定与生命各个阶段不良健康后果之间的联系,如不孕、胎儿发育和癌症。通过使用微核试验获得的横断面和饮食干预数据说明了后者,微核试验是诊断基因组不稳定和营养缺乏的有效生物标志物。讨论了基因组稳定性推荐膳食摄入量的概念以及如何实现这一目标,同时也探讨了营养基因组学在基因组稳定性方面的新兴领域。综述最后展望了基于基因组不稳定的诊断和营养治疗的疾病预防策略,即“基因组健康诊所”。
