Extra virgin olive oil extra protective

Ω

Eating a diet rich in the phenolic components of virgin olive oil represses several pro-inflammatory genes. Researchers writing in the open access journal BMC Genomics suggest that this partly explains the reduced risk of cardiovascular disease seen in people who eat a ‘Mediterranean diet’.

Francisco Perez-Jimenez from the University of Cordoba, Spain, led a team of researchers who studied the effects of eating a breakfast rich in phenol compounds on gene expression in 20 patients with metabolic syndrome, a common condition associated with increased risk of cardiovascular disease and type 2 diabetes.

Vitamin C aids in skin protection

Scientists have uncovered a new role played by Vitamin C in protecting the skin.

Researchers at the University of Leicester and Institute for Molecular and Cellular Biology in Portugal studied new protective properties of vitamin C in cells from the human skin, which could lead to better skin regeneration.

The work, by Tiago Duarte, Marcus S.

Gene expression

Gene expression is the process by which inheritable information from a gene, such as the DNA sequence, is made into a functional gene product, such as protein or RNA.

Several steps in the gene expression process may be modulated, including the transcription step and translation step and the post-translational modification of a protein.

Genomics


Genomics is the study of an organism’s entire genome. The field includes intensive efforts to determine the entire DNA sequence of organisms and fine-scale genetic mapping efforts.

Pharmacogenomics

Pharmacogenomics is the branch of pharmacology which deals with the influence of genetic variation on drug response in patients by correlating gene expression or single-nucleotide polymorphisms with a drug’s efficacy or toxicity.

Epigenetics

In biology, the term epigenetics refers to heritable changes in phenotype (appearance) or gene expression caused by mechanisms other than changes in the underlying DNA sequence (hence the name epi – “in addition to” – genetics).
