Supplementary Figure S1 from Targeted Exome Sequencing of Krebs Cycle Genes Reveals Candidate Cancer–Predisposing Mutations in Pheochromocytomas and Paragangliomas

<p>(A) Quantitative PCR analysis of RBP1 expression of the 49 tumors included in the study compared to controls comprising five tumors carrying mutation in Krebs cycle genes and five cases carrying mutations in RET or NF1. RU: relative units. (B) SDHB immunohistochemistry of tumor_4 compared to a positive control tumor carrying a non-SDH mutation. The scale bars represent 50μm. (C) Representation of DNA methylation (M_values) of the CpG island probes located within the SDHC locus of tumor_4 compared to a blood sample from the same patient and a control DNA. (D) Immunohistochemical staining of 5-hmC in IDH3B-mutated tumor. Nuclear 5-hmC was observed only in sustentacular and some stromal cells. The scale bar represents 50μm.</p>
