NCOR1 and hepatocellular carcinoma: As shown in Figure 1B, the level of NCoR transcripts in all HBX positive HCC cells was more or less similar to that of HBX negative HCC cells HepG2, thus suggesting that lack of NCoR protein in HBX positive HCC cells was most likely a post-transcriptional event such as destabilization of native state and degradation of protein rather than down regulation of NCoR transcript (Figure 1B).
