1 The suppressive effect of arsenic trioxide on TET2-FOXP3-Lyn-Akt axis-modulated MCL1 expression induces apoptosis in human leukemia cells. Arsenic Trioxide AKT serine/threonine kinase 1 Homo sapiens
2 In addition, ATO-treated U937 cells showed ROS-mediated inhibition of TET2 transcription, leading to downregulation of FOXP3 expression and in turn, suppression of FOXP3-mediated activation of Lyn and Akt. Arsenic Trioxide AKT serine/threonine kinase 1 Homo sapiens
3 Further, ATO-induced Akt inactivation promoted GSK3beta-mediated degradation of MCL1. Arsenic Trioxide AKT serine/threonine kinase 1 Homo sapiens
4 Transfection of constitutively active Akt expression abrogated ATO-induced MCL1 downregulation. Arsenic Trioxide AKT serine/threonine kinase 1 Homo sapiens
5 Thus, our data suggest that ATO induces mitochondria-mediated apoptosis in U937 cells through its suppressive effect on TET2-FOXP3-Lyn-Akt axis-modulated MCL1 transcription and protein stabilization. Arsenic Trioxide AKT serine/threonine kinase 1 Homo sapiens
