Characteristic ERK1/2 signaling dynamics distinguishes necroptosis from apoptosis
2021
International audience; ERK1/2 involvement in cell death remains unclear, although many studies have demonstrated the importance of ERK1/2 dynamics in determining cellular re- sponses. To untangle how ERK1/2 contributes to two cell death programs, we investigated ERK1/2 signaling dynamics during hFasL-induced apoptosis and TNF-induced necroptosis in L929 cells. We observed that ERK1/2 inhibition sensi- tizes cells to apoptosis while delaying necroptosis. By monitoring ERK1/2 activity by live-cell imaging using an improved ERK1/2 biosensor (EKAR4.0), we reported differential ERK1/2 signaling dynamics between cell survival, apoptosis, and nec- roptosis. We also decrypted a temporally shifted …

ERK involvement in cell death remains unclear, although many studies have demonstrated the importance of ERK dynamics in determining cellular responses. To untangle ERK’s contribution in two cell death programs, we investigated ERK signaling dynamics during hFasL-induced apoptosis and TNF-induced necroptosis in L929sAhFas cells. We observed that ERK inhibition sensitizes cells to apoptosis while delaying necroptosis. By monitoring ERK activity by live-cell imaging using an improved ERK biosensor (EKAR4.0), we reported differential ERK signaling dynamics between cell survival, apoptosis, and necroptosis. We also decrypted a temporally shifted amplitude- and frequency-modulated (AM/FM) ERK ac…
