Thioredoxin is a class of small redox proteins known to be present in all organisms. It plays a role in many important biological processes, including redox signaling. In humans, thioredoxins are encoded by TXN and TXN2 genes. Loss-of-function mutation of either of the two human thioredoxin genes is lethal at the four-cell stage of the developing embryo. Although not entirely understoo… WebThe complex interconnection between reactive oxygen species (ROS) levels and cancer is based on the precise fine-tuning of ROS production and clearance. The occurrence and progression of cancer leverage a slight increase in ROS levels. Thus, increased intracellular ROS levels and enhanced antioxidant defense systems have been considered one of the …
