While the treatment with Ru(II)-OH or NP2 slightly elevated the ROS levels inside the hypoxic cancer cells, the treatment with NP4 showed a strong enhancement of ROS
In particular, ROS affects T cell receptor signaling through several downstream signaling pathways (57, 61, 62), including mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinases (PI3K), and Janus kinase-signal transducer and activator of transcription 3 (JAK-STAT3)
