SBF2 and colorectal carcinoma: SBF2-AS1, as an oncogene, was identified to be overexpressed in CRC cell lines by Chen et al. In vitro experimental results showed that SBF2-AS1 positively regulates the expression of histone deacetylase 3 (HDAC3) in CRC cells via acting as a “sponge” of miR-619-5p and inhibiting its expression [30].
