ROS modulates CD133 levels in a context-dependent manner. Increased ROS species by aquaporin (AQ 3 y AQ9) channels can positively or negatively regulate CD133 expression because of its role in signaling modulation. ROS could favor JNK activation and downstream signaling. JNK induces FOXO3a release from 14–3-3 protein and subsequently its entry to the nucleus, wherein it competes with TCF4 to bind to β-catenin, leading to CD133 downregulation. By contrast, ROS also can improve CD133 expression by enhancing STAT3 and PI3K signaling. Created with BioRender.com
