SH-EP/SurvYFP cells were treated for 24 hours with increasing concentrations of YM55 (2-50 nM). (a) Mitochondrial structures were analyzed by CMXRos staining (300 nM) via live cell microscopy using an Axiovert200M microscope equipped with an ApoTome.2 system (Zeiss, Vienna, Austria). (b) Cell lysates were analyzed for Survivin expression by immunoblot, GAPDH served as loading control. Densitometric analyses were performed in the LabWorks software (UVP, Cambridge, UK).

SHEP/Ctr or SH-EP/Surv cells were treated with increasing concentrations of the Survivin-inhibitor YM155 for either 24 (c) or 48 (d) hours. The mean of five independent PI-FACS experiments is shown. Statistical differences between SHEP/Ctr and SH-EP/Surv cells were assessed by students t-test (***P<0.001, **P<0.01, *P<0.05). cell number [% of untreated control] S2 120 untreated 100 2DG *** w/oG 80 60 ns 40 20 0 SHEP/Ctr SHEP/Surv Supplemental Figure 2: SH-EP/Ctr cells and SH-EP/Surv cells were treated either with 15 mM 2DG or were cultivated in glucose-free media for 24 hours. Afterwards cell number was assessed by Casy® Cell counter (double measurements for each probe). Shown is the mean of four independent experiments. Statistical differences between SH-EP/Ctr and SH-EP/Surv cells were assessed by students t-test (***P<0.001).

SHEP/Surv cells were treated with 15 mM 2DG alone or in combination with 40 µM LY204002 for 0/1/2/4 hours. After cell lyses, Survivin expression was analyzed by immunoblot, GAPDH served as loading control. cell number [% of unterated control] S4 120 untreated QVD 100 Necro QVD+Necro 80 60 40 20 0 - 2DG + 2DG cell number [% of unterated control] SH-EP/Ctr 120 untreated QVD 100 Necro QVD+Necro 80 60 40 20 0 - 2DG + 2DG SH-EP/Surv Supplemental Figure 4: Cell number after 2DG treatment. SH-EP/Ctr (upper panel) and SHEP/Surv cells (lower panel) were treated for 24 hours with 15 mM 2DG with or without pre-incubation of 10 µM QVD, 20 µM Necrostation or a combination of both. Cell number was assessed by counting in a Casy® Cell counter System of four independent experiments. S5 Supplemental Figure 5: Survivin is a candidate for lysosomal degradation due to the basicity of its C-terminal coiled coil domain. Basic amino acids (Lys, Arg) in the coiled coil domain of Survivin are highly conserved among different mammalian species. Basic amino acids are shown in black (human), red (mouse) and green (rat).

SHEP/Surv-shCtr and SH-EP/Surv-shParkin-cl13 cells were treated with 15 mM 2DG for four hours. (a) Whole cell lysates were analyzed for Survivin and pParkin expression. GAPDH served as loading control. (b) Mitochondrial and cytoplasmic lysates were analyzed for Survivin. CoxIV (mito) and Tubulin (cyto) served as purification controls.

(a) STA-NB15 cells were treated with increasing concentrations of YM155 (5 -100 nM). Cell death was analyzed by FACS analyses of PI-stained nuclei according to Nicoletti et al. (b) Immunoblot analyses of Survivin expression in STA-NB15 cells after treatment with 50 nM YM155 for the times indicated. Tubulin served as loading control.
