چکیده
سرطان پروستات با اختلال در تعادل میان بقا و مرگ سلولی، یکی از چالش‌های مهم در فیزیولوژی سرطان محسوب می‌شود و تمرین ورزشی می‌تواند به‌عنوان یک مداخله غیردارویی بر مسیرهای مولکولی آن اثرگذار باشد. هدف پژوهش حاضر، مقایسه اثر تمرینات هوازی تداومی و هوازی تناوبی بر مسیرهای مولکولی آپوپتوز در بافت پروستات موش‌های ویستار مبتلا به سرطان پروستات بود. در این مطالعه تجربی، 50 موش نر ویستار به‌صورت تصادفی در پنج گروه 10 تایی شامل کنترل سالم، Sham، سرطان بدون تمرین، سرطان + تمرین هوازی تداومی و سرطان + تمرین هوازی تناوبی قرار گرفتند. پس از القای سرطان پروستات، گروه‌های تمرینی به مدت 8 هفته و 5 جلسه در هفته روی تردمیل تمرین کردند. تمرین تداومی با شدت حدود 60 درصد ظرفیت بیشینه و تمرین تناوبی با وهله‌های شدید 85 تا 90 درصد ظرفیت بیشینه و بازیافت فعال 50 تا 60 درصد اجرا شد. پس از پایان مداخله، بیان ژن‌های p53، Caspase-3، Bax، Bcl-2 و NF-κB در بافت پروستات با روش Real-Time PCR بررسی شد و نسبت Bax/Bcl-2 محاسبه گردید. داده‌ها با استفاده از MANOVA، ANOVA یک‌طرفه و آزمون تعقیبی توکی در نرم‌افزار SPSS نسخه 27 تحلیل شدند. یافته‌ها نشان دادند که سرطان پروستات موجب کاهش p53، Caspase-3 و نسبت Bax/Bcl-2 و افزایش NF-κB شد. هر دو نوع تمرین هوازی این تغییرات را تعدیل کردند، اما تمرین تناوبی نسبت به تمرین تداومی اثر قوی‌تری در افزایش p53، Caspase-3 و Bax/Bcl-2 و کاهش NF-κB نشان داد.

چکیده English

Prostate cancer is considered one of the major challenges in cancer physiology due to disruption in the balance between cell survival and cell death. Exercise training may act as a non-pharmacological intervention capable of influencing the molecular pathways involved in this process. The aim of the present study was to compare the effects of continuous aerobic training and interval aerobic training on the molecular pathways of apoptosis in the prostate tissue of Wistar rats with prostate cancer. In this experimental study, 50 male Wistar rats were randomly assigned to five groups of 10 animals each: healthy control, sham, cancer without training, cancer + continuous aerobic training, and cancer + interval aerobic training. Following the induction of prostate cancer, the training groups performed treadmill exercise for 8 weeks, 5 sessions per week. Continuous aerobic training was performed at approximately 60% of maximal capacity, whereas interval aerobic training consisted of high-intensity bouts at 85–90% of maximal capacity interspersed with active recovery at 50–60%. At the end of the intervention, the expression levels of p53, Caspase-3, Bax, Bcl-2, and NF-κB genes in prostate tissue were assessed using real-time PCR, and the Bax/Bcl-2 ratio was calculated. Data were analyzed using MANOVA, one-way ANOVA, and Tukey’s post hoc test in SPSS version 27. The findings showed that prostate cancer decreased p53, Caspase-3, and the Bax/Bcl-2 ratio, while increasing NF-κB expression. Both types of aerobic training moderated these alterations;
