Abstract

Background and objectives: It has been reported that deep-fried oils (DFOs) used in the preparation of fast foods can affect the immune system. On the other hand, regular physical activity and proper nutrition, in addition to affecting physical function, have a tremendous impact on the immune system. The aim of the present study was to investigate the anti-inflammatory effects of aerobic training (T) and octopamine (O) consumption in the heart tissue of rats fed DFO.
Methods: In this experimental study, 25 male Wistar rats with mean age of 20 weeks old and weighing 300- 350 were purchased and divided into 5 groups of 5 rats, including: 1) control, 2) DFO, 3) DFO+T, 4) DFO+O and 5) DFO+T+O. During four weeks, groups 2- 5 received DFO by gavage; groups 3- 5 ran on treadmill (with speed of 50% Vo2max in the first week which reached 65% Vo2max in the last week) five sessions per week and 20 minutes per session and groups 4-5 received 81 μmol/kg octopamine supplement peritoneally for 5 days per week. Nuclear factor kappa B (NF-κB) and tumor necrosis factor-alpha (TNF-α) gene expression were measured in heart tissue.
Results: DFO significantly increased NF-κB (P=0.005) and TNF-α (P=0.001) gene expression levels; T significantly on decreased NF-κB (P=0.01) and TNF-α (P=0.007) gene expression levels; O consumption significantly decreased NF-κB (P=0.001) and TNF-α (P=0.001) gene expression levels; however, the interactive effects of T and O consumption on NF-κB (P=0.57) and TNF-α (P=0.20) gene expression levels was not significant.
Conclusion: It seems that T and O consumption alone have anti-inflammatory effects on the heart tissue of rats fed DFO, however T and O do not have anti-inflammatory interactive effects.

Abstract

Various investigation has shown the magnitude role of adenosine receptors in cancer development. The A1, A2A, A2B, and A3 G-protein-coupled cell surface Adenosine Receptors (ARs) are found to be upregulated in many types of cancers. The adenosine receptor function has been affected by specific ligands such as agonists and/or antagonists regulated cancer (Neoplasms) cells proliferation via signaling pathways. Adenosine not only is an important intermediate metabolite but also acts as the essential ligand of adenosine receptors in physiological and pathological conditions. Furthermore, many studies have shown that adenosine receptors expression has increased in many types of cancer. In this review, we first describe adenosine's role in physiological condition and in cancer development. We further, discuss the type of adenosine receptors, distribution, expression, and their roles in cancer.
