چکیده مقاله :
زمینه و هدف: ملانوما وخیم ترین نوع سرطان پوست است که از سلول های رنگدانه ای ملانین تشکیل شده است. هدف از تحقیق حاضر بررسی تاثیر تمرینات استقامتی و مصرف گزنه بر بیان ژن BCL-2و TNF-αدر موش های مبتلا به سرطان ملانوما بود.روش کار: آزمودنی ها شامل موش های صحرایی نر ویستار بودند که پس از سازگاری دو هفته ای به صورت تصادفی به 4 گروه شامل گروه های: کنترل، تمرین، عصاره و تمرین+عصاره تقسیم شدند. برنامه تمرین شامل 30 دقیقه دویدن روی تردمیل بدون شیب و با سرعت 16 متر در دقیقه برای هفته اول بود و هر هفته یک متر بر دقیقه اضافه شد تا در هفته هشتم به 22 متر بر دقیقه رسید. یک هفته پس از القا سرطان ملانوما، گروه تجربی میزان 30 mg/kg/dayعصاره اتانولی گیاه گزنه را به روش خوراکی و به مدت 8 هفته مصرف کردند.برای اندازه گیری میزان بیان ژن از RT PCR استفاده شد.یافته‌ها: تجزیه و تحلیل داده ها نشان داد که مصرف عصاره گزنه و تمرینات استقامتی بر سطح بیان ژنBCL-2 و TNF-αدر موش های مبتلا به سرطان ملانوما در گروه های مختلف کاهش معناداری دارد(به ترتیب p=0.000 ,p=0.025). هم چنین نتایج نشان داد که تفاوت سطح تغییرات بیان ژنBCL-2 و TNF-αبین گروه تمرین+عصاره با گروه کنترل(به ترتیب p=0.002 ,p=0.014)کاهش معناداری داشت.نتیجه گیری: فعالیت بدنی منظم همراه با مصرف عصاره گزنه احتمالاً می تواند از طریق کاهش عوامل التهابی منجر به کاهش عوامل ضد آپوپتوزی و ایجاد آپوپتوز در سلول های سرطانی شود.
Inroduction & Objective: : Melanoma is the most serious type of skin cancer, which is made up of melanin pigment cells.The aim of this study was to evaluate the effect of endurance training and nettle consumption on BCL-2 and TNF-α gene expression in mice with melanoma.Material and Methods: The subjects included male Wistar rats that after two weeks of adjustment were randomly divided into 4 groups including: control, exercise, extract and exercise + extract. Exercise program included 30 minute of running on a treadmill was steep and at a speed of 16 meters per minute for the first week, and every week one meter per minute was added until the eighth week it reached 22 meters per minute. One week after melanoma induction, the experimental group consumed 30 mg / kg / day of nettle ethanol extract orally for 8 weeks. RT PCR was used to measure gene expression.Results: Data analysis showed that consumption of nettle extract and endurance training significantly reduced the expression level of BCL-2 and TNF-α genes in mice with melanoma in different groups (p = 0.000, p = 0.025, respectively). The results also showed that the difference in the level of changes in BCL-2 and TNF-α gene expression between the exercise and extract group with the control group (p = 0.002, p = 0.014, respectively) was significantly reduced.Conclusion: Regular physical activity combined with consumption of nettle extract can probably reduce anti-apoptotic factors and cause apoptosis in cancer cells by reducing inflammatory factors.
