CD47 and glioblastoma: NF-κB in coupling FAO and CD47 anti-phagocytosis was further supported by CGGA database analysis that identified a cluster of NF-κB subunits was tightly correlated with the mRNA levels of CD47 in GBM patients, though the correlation was detected in both primary and recurrent GBM (Supplementary Fig. 6a, b), suggesting that FAO-mediated CD47 transcription is associated with FAO metabolites.
