Heat Shock Proteins 27 and 60 Serum Levels in Patients with Gastrointestinal Cancer and Acute Myocardial Infarction in Birjand, Iran

Introduction: Cancer and myocardial infarction are lethal diseases. Their prevalence is increasing worldwide. In both diseases, the level of oxidative stress rises because of tissue damage. The aim of this study was to evaluate the serum levels of heat shock protein 27 and heat shock protein 60 in patients with cancer and myocardial infarction, and then compare them with healthy individuals.Materials and Methods: After blood samples were collected from the participants, plasma and serum were separated from these samples for further examination. The serum levels of heat shock protein 27 and heat shock protein 60 were measured with related kits in 30 patients with cancer and 30 patients with acute myocardial infarction, followed by 30 healthy individuals. The collected data were then analyzed in the Statistical Package for the Social Sciences software (version 22).Results: The mean serum levels of heat shock protein 27 in cancer patients (25.21 ± 5.57 ng/mL) and in patients with myocardial infarction (45.23 ± 7.43) were significantly higher than those in healthy individuals (10.61 ± 3.11; P<.05). In addition, the mean serum levels of heat shock protein 60 in patients with cancer (19.23 ± 3.41 ng/mL) and patients with myocardial infarction (22.23 ± 2.25 ng/mL) were significantly higher than those in healthy individuals (8.38 ± 2.53; P<.05).Conclusion: An increase in the serum levels of heat shock proteins 27 and 60 was observed in patients with cancer and myocardial infarction. Therefore, we can suggest that these biomarkers should help surgeons or physicians to diagnose the diseases.
