PLK1 and hepatocellular carcinoma: Unexpectedly, after detecting the transcriptional levels of TERT and the expression levels of GABPA (Figures 4A and B and S4A), we found that PLK1 inhibitor did not affect the transcriptional levels of TERT (Figure 4A and B) and had little effect on the expression of GABPA in all HCC cells (Figure S4A).
