Fig. 1. High-level expression of classical HLA Class II genes in high-risk neuroblastoma and its clinical implications.
A HLA-related gene expression was examined for the high-risk subset of Cohort 1 by the R2. High-level expression of classical HLA-Class II genes (HLA-DRA, HLA-DRB1, HLA-DPA1, HLA-DPB1) was detected in high-risk neuroblastoma tissues. A similar trend was observed in Cohort 2 (see Fig. S1). B (a) HLA-DRA expression was significantly correlated with HLA-DRB1 expression in high-risk neuroblastomas of Cohort 1. (b) Combination of high HLA-DRA and HLA-DRB1 expressions was significantly associated with prolonged survival of the high-risk patients of Cohort 1. C (a) HLA-DPA1 expression was significantly correlated with HLA-DPB1 expression in high-risk neuroblastomas of Cohort 1. (b) Combination of high HLA-DPA1 and HLA-DPB1 expressions was significantly associated with prolonged survival of the high-risk patients of Cohort 1. The expression unit of genes in Cohort 1 is Reads Per Million (RPM). Average expression of each gene was shown as Log2 of RPM. Error bars indicate standard deviations.
