SOS2 and glioblastoma: Based on UALCAN results, we identified exocyst complex component 5 (EXOC5), protein phosphatase 2 regulatory subunit B’Epsilon (PPP2R5E), and son of sevenless homolog 2 (SOS2) to exhibit high correlations with MuD expression in GBM tumors from TCGA patients (Pearson’s correlation coefficient > 0.79) (Figure 4A).
