SOX9 and neuroblastoma: SOX9-AS1 was found to be distributed in the cytoplasm of both H1.Hesc (H1 human embryonic stem cell line) and NCI.H460 (non-small-cell lung cancer cell line), and in the nucleus of GM12878 (B-lymphoblastoid cell line), HepG2 (human hepatocellular carcinoma cell line), and SK.N.SH cells (human neuroblastoma cell line), but was not described in the MCF-7 luminal BRCA cell line (Fig. 5E), and LncLocator predictor showed that SOX9-AS1 was localized to the cytoplasm (Fig. 5F).
