Detection of ETNPPL in gliomas. (A) WB detection of ETNPPL in proteins extracted from indicated gliomas. ETNPPL is detected as a single band with the predicted size (55 kDa). The uncropped image of the WB is presented on Supplemental Fig. 8A. Oligo II: grade II oligodendrogliomas, Astro II and III: grade II and III astrocytomas. GBM: IDH1 non-mutated glioblastomas. β-actin detection was used for normalization. Quantification for ETNPPL is presented on the right-hand side panel (4 astrocytomas IDH1 R132H-mutated and 6 glioblastomas). Test = Mann-Whitney test (**p = 0.01). (B) Immunohistochemistry for ETNPPL (brown) in one IDH1-mutated diffuse grade II astrocytoma. The protein is present either in the nucleus (red arrow) or in the cytoplasm (black arrow) of cells. Scale bars = 150 μm. Nuclei are stained with hematoxylin.
