A wide variety of nutrients can have profound effect on the regulation of gene expression within different cells of the body. There are many different pathways of metabolism and ways of maintaining the body's homeostasis within the human body. The new science which is based ongenetics seeks to understand this relationship between nutrition and health. One must look at gene products and the physiological function of these products when faced with a particular nutrient. Certain genes may produce different products or proteins, depending on the way that the cell recognizes the nutrient. Every cell in the human body has a built in sensory system. Depending on the levels of nutrients detected, the protein expression of the cell varies. In order to more fully understand the ways in which nutrients may affect the expression of genes, more studies need to be done in the areas of protein expression and metabolite production.

Ailments and Protein Expression

We suffer from severe health ailments and among them type 2 diabetes is one. Type 2 Diabetes mellitus is caused by a wide interplay of genes and pathways. It deals ...
... with the bodies’ lipid metabolism and insulin sensitivity. Some genes involved in this form of diabetes are sterol response element binding protein and intronic single nucleotide polymorphism. Mutations in these genes have been related to increase in occurrence of type 2 diabetes. The branch of genetic science is highly interested in the genetic makeup of individuals. It is highly regarded in the area of individual based medicine. The main goal of genetic science is to personalize nutrition. This means that based upon one's genetic makeup, a certain diet can be constructed that prevents disease, enhances immunity, increases life span, and betters quality of life. In the present day, genetic science has not evolved to be beneficial on a large scale. There is still much work to be done on the subject. Once genetic science is able to say what a particular nutrient does to a gene, then the scientists can start to prescribe certain individual based diets.

DNA and Protein Expression

DNA methylation, a protein called histone protein which is structurally associated with DNA and the packaging of discrete segments of DNA is called Epigenetic or known as nucleosome. For cellular differentiation and gene expression of protein expression is epigenetic marketing is very important. And it also directs development of pluripotent and multi-potent cells. In gene expression of fully differentiated adult cells epigenetic marks participate and it also assists in turning genes on and off during cell's lifetime of activity it assists. DNA microarrays are slightly complicated, however basically thousands of microscopic spots of DNA may additionally be hooked up to an effective surface, usually glass or silicon. This gives upward thrust to the title "gene chip". A gene chip can be analyzed for coding structure. The coding structure can then be referenced against the information that exists on the gene databases. The genes will also be referenced to a person's personal DNA to watch changes and variations over time.
