NaIO3 induces Akt, ERK, JNK and p38 MAPK activation. a, b As indicated, cells were treated with NaIO3 at concentrations indicated for different intervals. Immunoblotting was conducted by specific antibodies to determine the total and phosphorylated forms of Akt, ERK, p38 MAPK  and JNK. Quantification of protein phosphorylation was determined by normalization with respective total protein levels. * p < 0.05, indicating significant activation effects of NaIO3 on signaling pathways. c-f Cells were pretreated with U0126 (ERK inhibitor, 10 μM) (c), SB203580 (p38 MAPK inhibitor, 10 μM) (d), SP600125 (JNK inhibitor, 10 μM) (e), Nec-1 (RIP1 inhibitor, 30 μM) (f) or NAC (10 mM) (f) for 15 min. Then cells were treated with NaIO3 (30 mM) for 3 h (c-e) or different time intervals (f). Cell lysates were collected for immunoblotting
