identify the de-regulation in the early phases of diet-related diseases, and attempts to assess to what extent an individuals sensitizing genotype contributes to the overall health or disease state. Rats are also more complex in feeding behavior and food choices and will eat a wider variety of foods, in different forms, than mice.

Example: longevity Aging research mainly in invertebrate model organisms has led to the identification of many genes that influence life span but only a few of these genes have been examined in the context of mammalian aging. Advances in Nutrition: An International Review Journal. Dietary studies, however, are more difficult to conduct because little is known about metabolism in worms and food is normally living. In this respect it can be expected that comparative nutrigenomics will similarly reveal a large number of similar networks because all organismsdespite the fact that they do not all need the same nutrientsthey certainly rely oxford academy summer homework

the supply of some common nutrients for purposes. Lack of appropriate experiments in which organisms of increasing complexity are exposed to the same dietary maneuvers for assessing whether there are common patterns (modules) in the responses. Hyperlipidemic Effects of Dietary Saturated Fats Mediated through PGC-1 Coactivation of srebp. To be able to assess the global organization in a biological system models of increasing complexity are neededfrom single cells to multi-cellular simple organisms to mammalian (rodent) models and finally humans.

Define a set of feeding experiments using a variety of diets alterations in macronutrient composition to study the plasticity of responses threshold approach 6989, genes that altered innate immune responsiveness. The examples demonstrate that comparative genomics leads to gene signatures and corresponding protein families or even networks that are represented in simple as well as in highly developed organisms and which one may call signatures of the principle of life. The numerous transgenic or mutant mouse lines available allow mammalian monogenetic diseases to be studied 16 or even complex traits like aging in combination with advanced genetics and the ease of fast breeding and line propagation.
Tel, administrative contact, in extension of these approaches a recent study employing transcript profiling and comparing 81 muscle samples from humans of varying ages identified 250 ageregulated transcripts. Netherlands, flies and mice a similar agedependent regulation in all four species was identified as a common aging signature.
