Abstract
Background: The mTORC1 pathway is one of the important pathways for protein synthesis in the heart, which can lead to physiological or pathological hypertrophy. Diabetes can lead to defects in this pathway. The aim of this study was to examine the effect of 4 weeks’ aerobic training on the content of mTORC1 signaling pathway proteins in heart tissue of type 1 diabetes rats.
Methods: In this experimental study, 16 Sprague-Dawley male rats (mean weight of 300 ± 20 gr) were selected and after induction of diabetes by STZ was randomly assigned into two groups: diabetic training and diabetic control. The experimental group performed HIIT training for 4 weeks’ accordance with the training program (each session 42 minutes, 10-20 m/m) for 4 weeks, while the control group did not have any training program. Dependent t-test and independent T-test were used to analyze the data
Results: Significant increase was observed in the content of AKT1 (p<0.015), mTOR (p<0.001), P70S6K1 (p<0.006), 4EBP1 (p<0.05) proteins in the aerobic training group compared to control group.
Conclusion: Aerobic training for 4 weeks enabled to activate the pathway AKT1/mTOR/P70S6K1 and AKT1/mTOR/4E-BP1 in mTORC1 pathway; therefore, due to cardiac complications in type 1 diabetic patients, aerobic training can lead to protein synthesis and physiological cardiac hypertrophy through mTORC1 pathway.

Abstract
Background: Artificial intelligence analysis based on the gene list obtained from the DisGeNET database identified the important genes involved in the heart damage process. Data enrichment highlighted the apoptosis signaling pathway as a vital pathway in cardiovascular risk. Hence, we estimated the binding affinity of chemical and plant bioactive molecules for cytochrome-c protein. Here, we performed to evaluate the effect of eight weeks of resistance training (RT) with Tribulus Terrestris (TT) consumption on the mechanism of apoptosis in the heart tissue of rats exposed to stanozolol.
Methods: Thirty-five male rats were divided into seven groups: (1) Control, (2) Stanozolol (ST), (3) ST + 100 mg / kg TT, (4) ST + 50 mg / kg TT, (5) ST + RT (SRT), (6) S + RT + 100 mg / kg T (SRTT100), and (7) ST + RT + 50 mg / kg T (SRTT50). Differential gene expression was measured by q-RT-PCR. In bioinformatics analysis, the apoptosis signaling pathway was defined as a critical process in heart damage. In addition, adverse effects of Tribulus Terrestris and stanozolol on heart tissue were detected through the apoptotic pathway by molecular docking.
Result: Resistance training along with 100 mg/kg reduced CRP and cytochrome-c Moreover, 100 mg/kg TT as a more favorable effect than 50 mg/kg TT
Conclusion: we showed the beneficial effects of Tribulus Terrestris, the plant’s bioactive compound that can reduce cardiovascular risks by impairing the formation of apoptosome assemblages and inflammation.
