A transcriptome-wide analysis in mice found that a protein-restricted (PR) diet during gestation resulted in differential gene expression in approximately 1% of the fetal genes analyzed (235/22,690). Specifically, increased expression was seen in genes involved in the p53 pathway, apoptosis , negative regulators of cell metabolism, and genes ...
Nutritional genomics, also known as nutrigenomics, is a science studying the relationship between human genome, human nutrition and health. People in the field work toward developing an understanding of how the whole body responds to a food via systems biology, as well as single gene/single food compound relationships.
All life on Earth is influenced by the different flows of its environment, yet in humans, different environmental conditions such as poverty, alcohol, stress, malnutrition, exposure to pollutants, man-made chemicals, and synthetic drugs can lead to epigenetic-related illnesses/diseases with certain disease-specific genes typically being activated or deactivated.

It is an epigenetic process that involves DNA methylation and histone methylation without altering the genetic sequence. These epigenetic marks are established ("imprinted") in the germline (sperm or egg cells) of the parents and are maintained through mitotic cell divisions in the somatic cells of an organism.
DNA methylation is a key regulator in epigenetic modification during mammalian cell development and differentiation. In mouse models, excess levels of SAM have been implicated in erroneous methylation patterns associated with diabetic neuropathy. SAM serves as the methyl donor in cytosine methylation, which is a key epigenetic regulatory ...
The progeny of mice survived the Candida albicans infection via functional, transcriptional, and epigenetic changes linked to the immune gene loci. [78] The responsiveness of myeloid cells to the Candida albicans infection increased in inflammatory pathways, and resistance was increased to infections in the next generations. [ 78 ]
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).
