(C) Mouse lung fibroblasts expressing either Akt1, Akt2, or Akt3 and L929 lysates were harvested and western blotted using the indicated antibodies. In all graphs, averageSD was plotted.(TIF) pone.0056576.s002.tif (241K) GUID:?ABB59C13-3EC7-4D6C-8BEF-D434A601884F Figure S3: RIP1 kinase-dependent increase in Akt Thr308 phosphorylation during necroptosis. (A, B) L929 cells treated with zVAD.fmk (A) or TNF (B) for the indicated period of time followed by assessment of cell viability. (C) Cells were serum starved followed by treatment with IGF alone or IGF/zVAD.fmk and samples were collected at the indicated time points for western blot. (D,E) L929 cells were stimulated with bFGF and/or zVAD.fmk and Nec-1 (N1) for the indicated periods of time. Samples were analyzed using phospho-Thr308, phospho-Ser473 and pan-Akt ELISAOne assays. Phospho-signals were normalized to pan-Akt. Fold induction over control cells is plotted.

(A) Necroptosis was induced by zVAD.fmk or TNF in the presence of 2 M PD173074 or 20 M PD166866 for 9 hrs followed by western blot. (B,C) Cells were stimulated with TNF under normal serum (B) or serum free (C) conditions for the indicated periods of time followed by western blot.(TIF) pone.0056576.s004.tif (586K) GUID:?78CF27E2-3988-44ED-BCB8-271ABA19F834 Figure S5: Downstream Akt signaling contributes to the control of necroptosis. (A,B) L929 were stimulated with zVAD.fmk (A) TNF (B) for the indicated periods of time, followed by western blot using indicated antibodies. (C,D) L929 were stimulated with TNF or zVAD.fmk in the presence of the indicated concentrations of PF-4706871. Viability was determined after 24 hr (C). Western blot samples were collected after 9 hr (D). (E) L929 cells had been transfected with S6 siRNAs. After 48 hr, necroptosis was induced by zVAD and TNF.fmk for 24 hr. Inset, degrees of S6 had been motivated 48 hr after transfection.

(A,B) L929 cells had been activated by zVAD.fmk (A) and individual TNF (B) for 9 hr. Cell lysates Gfap had been put through mouse TNF ELISA. (C) L929 cells had been activated by zVAD.fmk and TNF in the current presence of either Nec-1 accompanied by dimension of TNF mRNA amounts by qRT-PCR in 9 hr. (D) L929 cells had been activated by zVAD.fmk and TNF in the current presence of Akt inh VIII (10 M), MK2206 (10 M) and TCN (100 M) accompanied by traditional western blot in 9 hrs. (E) Cells had been activated with TNF for 15 min or 9 hr in the current presence of Nec-1, Akt inh rapamycin and VIII. Western Schisandrin B blot examples had been gathered after 9 hr. (F) L929 cells had been activated with bFGF and zVAD.fmk (serum Schisandrin B free of charge circumstances) for 15 min and 9 hr in the current presence of Akt inh. VIII and examined by traditional western blot.
