July 19, 2018 / BIOON / - cancer scientists from the University of New South Wales found that important parts of our DNA are not easy to repair and restore after damage caused by sunlight Photo source: unsplash / Chris slupski's discovery, recently published in nature, will help researchers understand why mutations accumulate in some parts of our DNA For this study, Dr Rebecca Poulos and his colleagues studied DNA mutations in more than 1000 tumor samples to better understand how tumors form and grow "Our genes are very important for the function of our cells." Rebecca explains "We have studied the part of our DNA that regulates the expression of genes in cells." "We found that some of these important regulatory regions in melanoma are highly mutated." Then they went deeper into these areas of DNA and found that they were not easy to repair after being exposed to sunlight "We don't know how many of these mutations directly lead to cancer." "But our study highlights the importance of sunscreen in summer," says Rebecca (BIOON Com) reference: stay sun safe for your DNA
