Supplementary Figure 4: The oncogenic effect of ERBB3 mutants in OCUG-1 cells.

OCUG-1 cells were transiently transfected with vector expressing ERBB3-WT or mutants, and cell viability was determined by MTT assay. Data represent the means ± s.e.m. of three independent experiments (*P < 0.05, **P < 0.01 compared to cells transfected with the control vector; §P < 0.05, §§P < 0.01 compared to cells expressing ERBB3 WT).
