Nutritional genomics has exploded in the last decade, yielding insights-both nutrigenomic and nutrigenetic-into the physiology of dietary interactions and our genes. Among these are insights into the regulation of magnesium transport and homeostasis and mechanisms underlying magnesium's role in insulin and glucose handling. Recent observational evidence has attempted to examine some promising r...

Microarrays represent a powerful tool for studies of diet-gene interactions. Their use is, however, associated with a number of technical challenges and potential pitfalls. The cost of microarrays continues to drop but is still comparatively high. This, coupled with the complex logistical issues associated with performing nutritional microarray studies, often means that compromises have to be m...

Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders in women with a heterogeneous clinico-pathologic spectrum characterised by varying degrees ovulatory dysfunction and clinical and/ or biochemical features hyperandrogenism. The etiopathogenesis PCOS remains controversial multiple genetic variants environmental factors interacting together to foster development feat...

The new scientific field of nutrigenomics utilizes genomic tools, like microarrays, to analyze metabolic adaptations induced by variations in nutritional status. Here we describe how transcriptional regulation patterns caused by nutritional changes can be identified using gene expression profiling. This includes technical remarks on microarray analysis and data processing, as well as giving bio...

Comprehensive investigation of nutritional health effects at the molecular level requires the understanding of the interplay between three genomes, the food, the gut microbial, and the human host genome. Food genomes are researched for discovery and exploitation of macro- and micronutrients as well as specific bioactives, with those genes coding for bioactive proteins and peptides being of cent...

Now more than ever, we have begun to appreciate the roles of individual physical and genetic variation in health and medicine. A great deal of research attention has recently been devoted toward personalized medicine, in which technologies like medical genetics are used to determine information such as how a patient is likely to respond to a treatment or the optimal dose of a drug. While drug t...
