The next publication is resuming our latest discussions about cell death. UVA radiation is known to induce oxidative stress which leads to cell damage requiring all organisms to protect themselves with free radical scavengers like ascorbic acid (vitamin C). A team of scientists (Ganna Petruk, Assunta Raiola, Rita Del Giudice, Amalia Barone, Luigi Frusciante, Maria Manuela Rigano, and Daria Maria Monti) from the University of Naples and Istituto Nazionale di Biostrutture e Biosistemi have published their work regarding a tomato genotype rich in ascorbic acid and were able to show its protective effects on human keratinocytes exposed to UVA stress. This might help to breed tomatoes with higher antioxidant levels contributing to human health when applied in a diet. The NanoPhotometer® was used to quantify ascorbic acid according to Stevens et al. and Rigano et al. at 525 nm using 6% TCA as reference.
