Using RT‐PCR, we screened the expression of the above‐altered lipid metabolism‐related genes in NB cell lines (SK‐N‐BE and SK‐N‐SH) as well as NB environment cell lines (HUVEC, monocytes, macrophages, and T cells) and found that FABP4 was enriched in blood‐cell lineages but scarcely expressed in NB cell lines. The gene discussed is FABP4; the disease is neuroblastoma.
