CT04 suppresses SC proliferation. (A–G) EdU staining showed that EdU positive ratio was suppressed by CT04 treatment (n = 15, *P < 0.05). (H) Statistical graph of cell density indicated that the number of total cells (positive for 4′,6-diamidino-2-phenylindole (DAPI)) was decreased in the presence of CT04 (n = 15, *P < 0.05). (I) Water-soluble tetrazolium salt-1 (WST-1) measurement revealed that CT04 markedly decreased the absorbance value compared to the control group (n = 4, *P < 0.05). (J,K) Western blotting displayed that the expression of PCNA was remarkably down-regulated in the CT04 treated cells (n = 6, *P < 0.05). The blots were cropped from different parts of the same gel. The expression level of PCNA in the control group was normalized to 1.
