Cytoplasmic ros measurement
WebCytosolic superoxide can be measured using the DHE fluorescent probe. Cells grown in multiwell plates should be incubated for 20 min (needed to allow the probe to enter the cell and start the reaction) at 37 °C in 0.5 ml of DMEM containing 0.5 μ M DHE. After the incubation, cells should be washed twice with PBS. WebOur results identify a cytoplasmic pathway for ROS-induced ATM activation of TSC2 to regulate mTORC1 signaling and autophagy, identifying an integration node for the cellular damage response with key pathways involved in metabolism, protein synthesis, and cell survival.
