Article Title: Targeting of neuroblastoma cells through Kynurenine-AHR pathway inhibition.

doi: 10.1111/febs.17109

Figure Lengend Snippet: Fig. 7. Cellular effects of ATRA or irinotecan in combination with 680C91 in neuroblastoma. Working model of the mechanism of action of the chemotherapeutic agents ATRA and irinotecan along with inhibitors of the Kyn-AHR pathway in neuroblastoma. RAR: Retinoic Acid Receptor. AHR can be activated by Kyn and ATRA in neuroblastoma cells leading to the transcriptional activation of AHR transcriptional signature. Inhibiting Kyn production synergizes with ATRA and irinotecan to inhibit neuroblastoma cell growth.
