SP1 and neuroblastoma: Consistently, our own ChIP assays showed that an anti-N-Myc antibody efficiently immunoprecipitated the region of the linc00467 gene core promoter enriched in the Sp1-binding sites in BE(2)-C neuroblastoma cells (Figure 1F), in addition to the gene core promoter of ODC1 (Figure S1), a well-known Myc target gene.
