Figure 1. Erythroid progenitor sensitivity assay of erythropoietin (EPO)
Burst-forming-unit-erythroid (BFU-E) colonies were enumerated and expressed as a percentage of maximum at stimulation with different EPO concentrations from each family member and controls.

Figure 2. VHL structural and functional studies
A–B: The efficient reduction of HIF1A by reintroduction of the VHL mutants into VHL-deficient 786-0 cells in contrast with wild-type and empty vector. C-D: Cyclohexamide (CHX) chase assay for protein half-life shows that mutant VHL proteins have decreased half-lives. 786-0 cells stably transfected with VHL variants and treated with CHX (200μM) for 4 h; hourly lysates were analysed by Western blot.
