Here comes the sun

 
 
 

Exposure to ultraviolet (UV) radiation, a form of energy emitted by the sun that we can’t see or feel, is the principal environmental cause of skin cancer, and causes mutations in the p53 gene (fundamental in the mechanisms protecting skin cells from malignant transformations). In the majority of the most common skin cancers, these mutations (a marker of early UV-induced carcinogenesis) can be observed and quantified in the blood serum, the fluid that remains when you remove certain factors from blood plasma.

study in Australian adults (Australia receives high amounts of UV radiation) are shown an inverse association between EPA and DHA blood serum concentrations and p53 reaction in the epidermis: people in the highest group of serum omega-3 fatty acid concentrations had lower p53 immunoreactivity. That is to say there is a dose-response relationship: the more EPA and DHA, the less mutant p53 protein. These results, that corroborate others (that we will deal with in another post), show that increased intake of omega-3 fatty acids could have a preventive effect on skin cancer. Do you like the sun?
