1 We also found that low levels of pyruvate contributed to proliferation of CCA cells and confirmed that the upstream target is cMyc. Pyruvic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
2 Conversely, high activity of HDAC3 stabilized cMyc protein by preferential deacetylating cMyc at K323 site, which further contributed to the low pyruvate levels. Pyruvic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
3 Conversely, high activity of HDAC3 stabilized cMyc protein by preferential deacetylating cMyc at K323 site, which further contributed to the low pyruvate levels. Pyruvic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
4 CONCLUSIONS: Collectively, our findings identify a role for promoting the low pyruvate levels regulated by c-Myc, and its dynamic acetylation in cancer cell proliferation. Pyruvic Acid MYC proto-oncogene, bHLH transcription factor Homo sapiens
