Experimental details: TOP: Intracellular staining of untreated (left) or 15-minute IL-2-treated (right) mouse splenocytes with Anti-Mouse CD304 (Neuropilin-1) PerCP-eFluor® 710 (Product # 46-3041-82) and Anti-Human/Mouse phospho-STAT5 (Y694) APC. CD4+ cells in the lymphocyte gate were used for analysis. BOTTOM: Intracellular staining of untreated (orange histogram) or 15-minute IL-2-treated (purple histogram) mouse splenocytes with Anti-Human/Mouse phospho-STAT5 (Y694) APC. CD4+CD304+ cells in the lymphocyte gate were used for analysis. In both panels, cells were stained using the Fixation/Methanol protocol.

Experimental details: Figure 1 EPO regulates EPO-R expression and elicits downstream signalling in RKC-2 cells. All graphs represent mean +- SEM. ( A-B) RKC-2 cells were cultured in the presence or absence of 5 U/ml EPO for 24 h. ( A ) EPO-R transcript levels were evaluated by RT-PCR, N = 5-8, *p < 0.05. Rat BMDM (positive control) were considered as 1. ( B ) EPO-R surface expression was evaluated by flow cytometry. Top: Grey and black line histograms depict surface EPO-R in control (considered as 1) and EPO-treated cells, respectively. Full histogram depicts FITC conjugated Goat anti mouse antibody. Bottom: Quantification of surface EPO-R, N = 7, **p < 0.01. ( C-D ) RKC-2 cells were stimulated for 0, 10 and 30 min with 10 U/ml EPO. Top: Grey, black and dashed histograms represent 0, 10 and 30 min EPO-treated cells, respectively. Bottom: The graphs depict quantification of mean fluorescence intensity (MFI) of flow cytometry analysis for p-ERK1/2 and p-STAT5, ( C ) and ( D ), respectively. Levels at 0 min were considered as 1, N = 4-5, **p < 0.01, *p < 0.05.

Experimental details: Figure 5. EPOR and LEPR switch residues are required for Epo and Leptin-induced STAT phosphorylation. ( a,b ) Stable Ba/F3 cell lines expressing wild-type, full length mouse EPOR or LEPR were generated and analyzed for STAT phosphorylation by flow cytometry after stimulation with EPO or leptin. ( a ) Representative plots comparing phospho-STAT5 staining of parental Ba/F3 cells or Ba/F3 cells expressing EPOR. Cells were stimulated with 1 nM mouse EPO for 15 min before fixation, staining, and analysis. ( b ) Representative plots comparing phospho-STAT3 staining of parental Ba/F3 cells or Ba/F3 cells expressing LEPR. Cells were stimulated with 100 pM mouse Leptin for 4 hr prior to fixation, staining, and analysis. ( c ) Analysis of STAT5 phosphorylation by flow cytometry for EPOR wild-type, switch region, and box1 mutants, stimulated with 1 nM EPO as in ( a ). Mean levels of STAT5 phosphorylation were assessed in three separate experiments, with wild-type signal representing 100% in all three experiments. ( d ) Analysis of STAT3 phosphorylation by flow cytometry for LEPR wild-type, switch region, and box1 mutants, stimulated with 100 pM Leptin, as in ( b ). Mean levels of STAT3 phosphorylation was assessed in three separate experiments, with wild-type signal representing 100% in all three experiments. Error bars represent standard error of the mean (SEM). Figure 5--figure supplement 1. Analysis of Ba/F3 stable cell lines expressing EPOR or LEPR mutants. ( a ) Alignment of human

Experimental details: Figure 5--figure supplement 1. Analysis of Ba/F3 stable cell lines expressing EPOR or LEPR mutants. ( a ) Alignment of human and mouse sequences for EPOR and LEPR. Note the numbering differences for mouse versus human (minus one residue for EPOR and minus two residues for LEPR). Residues in the switch region and box1, which are mutated in our experiments, are completely conserved between human and mouse. ( b-c ) Receptor surface staining for stable cell lines expressing ( b ) EPOR variants and ( c ) LEPR variants. Plots represent cumulative events (Y axis) at or below a given staining level (X axis). ( d ) Representative raw flow cytometry histograms showing the phospho-STAT5 (EPOR) or phospho-STAT3 (LEPR) staining in unstimulated cells (black trace) or cells stimulated with cytokine (red trace) as described in Materials and methods.
