Reactive oxygen species (ROS) are a double-edged sword that possesses both beneficial and harmful effects. Although basic research on skin cancer prevention has undergone huge transformation, cases of recurrence with higher rates drug resistance some its drawbacks. Therefore, targeting mitochondria by ROS overproduction provides an alternate approach for anticancer therapy. In the present study, green-synthesized silver nanoparticles (AgNPs) were explored triggering production in A431...

Abstract Epithelial–mesenchymal transition (EMT) in cancer cells drives chemoresistance, yet the molecular events of EMT that underpin acquisition chemoresistance are poorly understood. Here, we demonstrate a loss gemcitabine chemosensitivity facilitated by human equilibrative nucleoside transporter 1 (ENT1) during pancreatic and identify cadherin switching from epithelial (E) to neuronal (N) type, hallmark EMT, contributes this loss. Our findings N-cadherin decreases ENT1 expression,...
