چکیده
مقدمه: سرطان سینه، یک بیماری چند عاملی و دارای پتانسیل کشندگی است که علاوه بر ژنتیک، عوامل محیطی زیادی در آن نقش دارند. هدف از انجام این تحقیق، بررسی بیان دو نشانگر زیستی Vascular endothelial growth factor messenger RNA (VEGF mRNA) و Cytokeratin-19 mRNA (CK19 mRNA) و نیز نشانگر زیستی پروتئینی VEGF در خون محیطی بیماران مبتلا به سرطان سینه بود.روش‌ها: 40 بیمار مبتلا به سرطان سینه (گروه مورد) با 40 فرد سالم (گروه شاهد) مقایسه شدند. از روش Real-time reverse transcriptase polymerase chain reaction (Real-time RT-PCR) برای تعیین میزان بیان دو نشانگر زیستی CK19 mRNA و VEGF mRNA استفاده شد. همچنین، پروتئین VEGF به روش Enzyme-linked immunosorbent assay (ELISA) اندازه‌گیری گردید.یافته‌ها: مثبت شدن نشانگر VEGF mRNA در گروه مورد در 30 نفر از 40 بیمار مشاهده شد. در گروه شاهد، 6 نفر از 40 نفر مثبت گزارش گردید. نشانگر CK19 mRNA در گروه مورد در 25 نفر از 40 نفر مثبت گردید و در گروه شاهد، در 7 نفر از 40 نفر مثبت گزارش شد. همچنین، سطح سرمی VEGF در 27 نفر از افراد گروه مورد مثبت بود.نتیجه‌گیری: در مجموع، می‌توان نتیجه‌ی این تحقیق در زمینه‌ی نشانگرهای سرطان سینه را به عنوان یک آزمایش تشخیصی غربالگری برای کشف زودرس بیماری در مراحل اولیه در نظر گرفت.

چکیده English

Background: Breast cancer is a multifactorial potentially lethal disease that is triggered by genetic factors as well as numerous environmental factors. The present research aimed to examine the expression of Vascular endothelial growth factor messenger RNA (VEGF mRNA), cytokeratin-19 mRNA (CK19 mRNA), and vascular endothelial growth factor (VEGF) protein biomarker in the peripheral blood of patients with breast cancer.Methods: 40 patients with breast cancer were compared to 40 healthy individuals. The real-time reverse transcriptase polymerase chain reaction (real-time RT-PCR) method was used to determine the expressions of the CK19 mRNA and VEGF mRNA biomarkers in the peripheral blood samples of the healthy participants and the patients. The VEGF protein was also compared using the (ELISA) method.Findings: The positive VEGF mRNA biomarker was observed in 30 of the 40 patients with breast cancer; thus the sensitivity of this marker was 75%. In the healthy participants group, 6 of the 40 participants showed a positive VEGF mRNA biomarker expression. The CK19 mRNA marker was positive in 25 of the 40 patients, which indicated a sensitivity of 62.5%. In the healthy participants group, the positive expression of the CK19 mRNA biomarker was observed in 7 of the 40 participants. VEGF was positive in 27 of the 40 patients. In the control group, 5 of the 40 participants showed the positive expression of this biomarker.Conclusion: In sum, based on the results of this research, the assessed breast cancer tumor markers can be used as screening tests for the early diagnosis of patients. To further prove the findings of this study, more extensive studies with larger sample sizes are recommended.
