[EX A]: vulnerable

[EX Q]: Context: The war had three phases. Initially it was a localized feud between supporters of Gebhard and those of the Catholic core of the Cathedral Chapter. With the election of Ernst of Bavaria as a competing archbishop, what had been a local conflict expanded in scale: Ernst's election guaranteed the military, diplomatic, and financial interest of the Wittelsbach family in the Electorate of Cologne's local affairs. After the deaths of Louis VI, Elector Palatine in 1583and William the Silent in 1584, the conflict shifted gears again, as the two evenly matched combatants sought outside assistance to break the stalemate. Finally, the intervention of Alexander Farnese, Duke of Parma, who had at his command the Spanish Army of Flanders, threw the balance of power in favor of the Catholic side. By 1588, Spanish forces had pushed Gebhard from the Electorate. In 1588 he took refuge in Strassburg, and the remaining Protestant strongholds of the Electorate fell to Parma's forces in 1589. 
 Question: After Louis VI, Elector Palatine, and Williant the Silent died, what set into motion the third phase of the war?
[EX A]: the intervention of alexander farnese

[EX Q]: Context: The generation of reactive oxygen species (ROS) is required for proper cell signaling, but must be tightly regulated to minimize deleterious oxidizing effects. Activation of the NADPH oxidases (Nox) triggers ROS production and, thus, regulatory mechanisms exist to properly control Nox activity. In this study, we report a novel mechanism in which Nox1 activity is regulated through the proteasomal degradation of Nox organizer 1 (NoxO1). We found that through the interaction between NoxO1 and growth receptor-bound protein 2 (Grb2), the Casitas B-lineage lymphoma (Cbl) E3 ligase was recruited, leading to decreased NoxO1 stability and a subsequent reduction in ROS generation upon epidermal growth factor (EGF) stimulation. Additionally, we show that EGF-mediated phosphorylation of NoxO1 induced its release from Grb2 and facilitated its association with Nox activator 1 (NoxA1) to stimulate ROS production. Consistently, overexpression of Grb2 resulted in decreased Nox1 activity, whereas knockdown of Grb2 led to increased Nox1 activity in response to EGF. CRISPR/Cas9-mediated NoxO1 knockout in human colon cancer cells abrogated anchorage-independent growth on soft agar and tumor-forming ability in athymic nude mice. Moreover, the expression and stability of NoxO1 were significantly increased in human colon cancer tissues compared with normal colon. Taken together, these results support a model whereby Nox1 activity and ROS generation are regulated by Grb2/Cbl-mediated proteolysis of NoxO1 in response to EGF, providing new insight into the processes by which excessive ROS production may promote oncogenic signaling to drive colorectal tumorigenesis. 
 Question: Which NADPH oxidase family member requires interaction with NOXO1 for function?
