DLX6 and hepatocellular carcinoma: Co-expression-based GSEA revealed that DLX6-AS1 was co-expressed with genes involved in the regulation of nuclear beta-catenin signaling and target gene transcription (Figure 4C), such as SALL4, ZCCHC12, and BCL9, suggesting that DLX6-AS1 may participate in beta-catenin-induced gene transcription in HCC.
