From: Correction to: Inhibition of mTORC1 through ATF4-induced REDD1 and Sestrin2 expression by Metformin
AMPK and ATF4 do not affect each other’s expression under metformin treatment. (a–d) H1299 cells were transfected with control, AMPKα, ATF4, REDD1, or Sestrin2 siRNA for 12 h and then treated with 10 mM metformin for 24 h. The indicated protein levels were estimated by western blot analysis. The blot is representative of two independent experiments. CTL: control, SESN2: Sestrin2
