The Effect of Aerobic Training and Octopamine Supplement on Gene Expression Levels of VEGF and PDGFR in the Heart Tissue of Rats Exposed to Deep Fried Oil

Deep-fried oils (DFO) produce toxins that endanger people's health. Using herbal supplements along with exercise training can help improve health. The purpose of this study was to investigate the effect of aerobic training (T) and octopamine (O) supplementation on VEGF and PDGFR gene expression levels in the heart tissue of rats poisoned with DFO.

In this experimental study, 25 male Wistar rats were purchased and placed in 5 groups of 5 animals, including: 1) control, 2) DFO, 3) DFO+T, 4) DFO+O and 5) DFO+T+O. Over a course of 4 weeks, rats in groups 2 to 5 received DFO by gavage, and rats in groups 3 and 5 ran on the treadmill 5 times a week with moderate intensity; also, rats in groups 4 and 5 received 81 μmol/kg octopamine supplement intraperitoneally 5 days a week. The Kolmogorov-Smirnov statistical test, independent samples t-test and two-way analysis of variance were used to analyze the research findings (p<0.05).

DFO had a significant effect on increasing the gene expression levels of VEGF (p=0.001) and PDGFR (p=0.002); training had a significant effect on the reduction of VEGF (p=0.001) and PDGFR (p=0.012); also, octopamine consumption had a significant effect on the reduction of VEGF (p=0.001) and PDGFR (p=0.045).

It seems that aerobic training and octopamine consumption alone have anti-inflammatory effects in the heart tissue of DFO-poisoned rats, however they do not have significant anti-inflammatory interactive effects.
