Sodium Tanshinone IIA Sulfonate Prevents Radiation-Induced Toxicity in H9c2 Cardiomyocytes

Figure 7

Radiation suppressed the growth of H9c2 cells via an apoptosis-dependent mechanism, and STS reversed it. PI staining and flow cytometric analyses were employed to examine apoptosis and the cell cycle distribution at 24 h after exposure to various doses of radiation (). (a) Representative flow cytometry graphs of the cell cycle analysis of cells irradiated with or without STS pretreatment. (b) The cell cycle analysis results of H9c2 cells are presented as the mean ± SD. and versus the control group; versus the corresponding radiation alone group.
