ABSTRACT OBJECTIVE:To investigate the improvement effects of Zingiber officinale decoction (ZOD) on doxorubicin
(DOX)-induced mitochondrial function injury of H9c2 cardiomyocytes. METHODS:Taking H9c2 cardiomyocytes as research
object,the effects of different concentrations of ZOD(0.125,0.25,0.5,1,2,4,8 mg/mL,by crude drug,the same below)on
its survival rate were investigated by CCK-8 assay. The effects of low,medium and high concentrations of ZOD(0.125,0.25,0.5
mg/mL)on the morphology of H9c2 cardiomyocytes after DOX(5 μmol/L)induced mitochondrial dysfunction were detected by
high content living cell imaging system. The relative number of cells,the relative fluorescence intensity of living cells and the
relative fluorescence intensity of dead cells were analyzed quantitatively. The effects of ZOD(0.5 mg/mL)on related indexes of
mitochondrial respiratory function(oxygen consumption rate,extracellular acidification rate,baseline oxygen consumption rate,
baseline extracellular acidification rate,stress oxygen consumption rate and stress extracellular acidification rate) and energy
metabolism(basic respiration level,maximum respiration level,ATP production level,H proton leakage level,spare respiration
+
level and non-mitochondrial respiration level)were detected by bioenergy analyzer. RESULTS:After treated with 0.125,0.25,0.5
mg/mL ZOD,the survival rate of H9c2 cardiomyocytes were increased significantly(P<0.01)or had no statistical significance
(P>0.05). After DOX induced mitochondrial dysfunction of H9c2 cardiomyocytes,pretreated with 0.125,0.25,0.5 mg/mL(or
0.5 mg/mL)ZOD,the morphology of H9c2 cardiomyocytes returned to normal and showed regular fibrous adherent distribution.
The relative cell number,fluorescence intensity of living cells,oxygen consumption rate,extracellular acidification rate,baseline
oxygen consumption rate,baseline extracellular acidification rate,stress oxygen consumption rate,stress extracellular acidification
rate,basic respiration level,maximal respiration level,ATP production level,spare respiration level and non-mitochondrial
+
respiration level were all significantly increased(P<0.05 or P<0.01),while relative dead cell fluorescence intensity and H proton
leakage level were significantly decreased (P<0.01). CONCLUSIONS: ZOD can improve the respiratory function and
