STAT3-mediated activation of mitochondrial pathway contributes to antitumor effect of dihydrotanshinone I in esophageal squamous cell carcinoma cells

Figure 2 Dihydrotanshinone I induces cell cycle arrest in the G0/1 phase in esophageal squamous cell carcinoma cells. A and B: Cell cycle distribution after treatment with DHTS for 24 h in KYSE30 cells and Eca109 cells; C and D: Western blot analysis of proteins associated with the cell cycle in KYSE30 cells and Eca109 cells. ^aP < 0.05 vs control. DHTS: Dihydrotanshinone I.
