Figure 4. Gal-3 triggers apoptotic signaling in different T leukemia cell lines and PBMCs.
(A) Jurkat E6-1, CEM and human PBMC were incubated with Gal-3 in the presence or absence of U0126 for 18 h followed by analysis for p-ERK1/2 and cleaved caspase-3 and (B) p-PKC by western blotting. (C) Jurkat E6-1, CEM and human PBMCs were incubated with Gal-3 for 6 h and ROS production was detected by flow cytometry. (D) Jurkat E6-1, CEM and human PBMCs were incubated with Gal-3 for 18 h in the absence or presence of NAC and AEB071 followed by analysis of p-ERK1/2 and cleaved caspase-3 by western blotting.
