Changes in Serum Levels and Gene Expression of PGC-1α in The Cardiac Muscle of Diabetic Rats: The Effect of Dichloroacetate and Endurance Training
Objective: Physical activity leads to changes in the level of gene expression in different kinds of cells, including changes in mitochondrial biogenesis in the myocardium in diabetic patients. Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is a gene that plays an important ro...

Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is a gene that plays an important role in regulating mitochondrial biogenesis. The purpose of this study was to investigate changes in serum levels and cardiac muscle expression of PGC-1α in diabetic rats in response to the administration of dichloroacetate (DCA) and endurance training. Materials and Methods: In this experimental study, 64 male Wistar rats were selected and randomly divided into eight groups after induction of diabetes with streptozotocin (STZ). The endurance training protocol was performed on a treadmill for 6 weeks. Intraperitoneal injection of DCA of 50 mg/ kg body weight was used for the inhibition of Pyruvate Dehydrogenase Kinase 4 (PDK4) in the myocardium. Gene expression were measured using real-time polymerase chain reaction (PCR). One-way ANOVA and Tukey’s test were used to statistically analyze the data. Results: The results of the study showed that PDK4 gene expression in the endurance training group, diabetes+endurance training group, diabetes+endurance training+DCA group and endurance training+DCA group was higher compared to the control group. Expression of PGC-1α was higher in the endurance training group compared to the control group but was lower compared to the control group in diabetes+endurance training+DCA group and diabetes+DCA group (P<0.05). Conclusion: Considering that PGC-1α plays an important role in mitochondrial biogenesis, it is likely that by inhibiting PDK4 and subsequently controlling oxidation of fatty acid (FA) in the heart tissue, oxidative stress in the heart tissue of diabetic patients will be reduced and cardiac efficiency will be increased.https://celljournal.org/journal/article/fulltext/changes-in-serum-levels-and-gene-expression-of-pgc-1a-in-the-cardiac-muscle-of-diabetic-rats-the-effect-of-dichloroacetate-and-endurance-training.pdfendurance trainingdiabetesdichloroacetatemitochondrial biogenesis |

Objective: Physical activity leads to changes in the level of gene expression in different kinds of cells, including
changes in mitochondrial biogenesis in the myocardium in diabetic patients. Peroxisome proliferator-activated receptor
γ coactivator 1α (PGC-1α) is a gene that plays an important role in regulating mitochondrial biogenesis. The purpose
of this study was to investigate changes in serum levels and cardiac muscle expression of PGC-1α in diabetic rats in
response to the administration of dichloroacetate (DCA) and endurance training.
Materials and Methods: In this experimental study, 64 male Wistar rats were selected and randomly divided into eight
groups after induction of diabetes with streptozotocin (STZ). The endurance training protocol was performed on a
treadmill for 6 weeks. Intraperitoneal injection of DCA of 50 mg/ kg body weight was used for the inhibition of Pyruvate
Dehydrogenase Kinase 4 (PDK4) in the myocardium. Gene expression were measured using real-time polymerase
chain reaction (PCR). One-way ANOVA and Tukey’s test were used to statistically analyze the data.
Results: The results of the study showed that PDK4 gene expression in the endurance training group, diabetes+endurance
training group, diabetes+endurance training+DCA group and endurance training+DCA group was higher compared to
the control group. Expression of PGC-1α was higher in the endurance training group compared to the control group
but was lower compared to the control group in diabetes+endurance training+DCA group and diabetes+DCA group
(P<0.05).
Conclusion: Considering that PGC-1α plays an important role in mitochondrial biogenesis, it is likely that by inhibiting
PDK4 and subsequently controlling oxidation of fatty acid (FA) in the heart tissue, oxidative stress in the heart tissue of
diabetic patients will be reduced and cardiac efficiency will be increased. |
