Abstract:Abstract. The p53 gene— “the guardian of the genome”—is responsible for maintaining the integrity of the genome, along with cell cycle regulation, apoptosis, and cell differentiation. New analytical devices are needed to recognize the main alterations this gene could suffer, since it is one of the most frequent in human cancer. For this reason, we developed an electrochemical DNA biosensor with high sensitivity and specificity to monitor the 175p2 mutation of the p53 gene. We modified a screen-printed gold ele… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
