    ..The mutation of Val54Ala, but not Cys310Phe, significantly impaired this activity, suggesting that Val54 plays a critical role in recognition of the steroidal substrate. ..
  7. Matsunaga T, Kamase K, Takasawa H, Yamaji Y, Endo S, El Kabbani O, et al. Facilitation of 9,10-phenanthrenequinone-elicited neuroblastoma cell apoptosis by NAD(P)H:quinone oxidoreductase 1. Chem Biol Interact. 2018;279:10-20 pubmed publisher
    ..Taken together, PQ exposure produces large amounts of ROS in neuroblastoma cells via NQO1 up-regulation and resultant acceleration of its redox-cycling, followed by activation of the ROS-dependent apoptotic mechanism. ..
  8. Matsunaga T, Morikawa Y, Kamata K, Shibata A, Miyazono H, Sasajima Y, et al. ?-Pyrrolidinononanophenone provokes apoptosis of neuronal cells through alterations in antioxidant properties. Toxicology. 2017;386:93-102 pubmed publisher
