The aryl hydrocarbon receptor, AhR, can regulate Oct4, which is often expressed in cancer stem cells and promotes pluripotency and tumorigenesis. Here, in cancer stem cells, AhR is shown to be activated by the tryptophan derivative ITE, which causes transcriptional repression of Oct4 and reduced tumorigenesis.
