APOD and glioma: In contrast to ApoD-expressing glioma and astrocytic cell lines like 1321N1 cells (Bajo-Grañeras et al., 2011; Pascua-Maestro et al., 2017), no ApoD expression has been detected in SH-SY5Y neuroblastoma cells either by genome-wide transcriptome analyses (e.g., 0.0 FPKM for ApoD in http://systemsbiology.uni.lu/shsy5y/) or by immunodetection of ApoD protein (Pascua-Maestro et al., 2017).
