چکیده
مقدمه: قرارگیری در معرض فلزات سنگین مانند کادمیوم (Cd)، یکی از عوامل مهم آسیب کبدی با فعال‌سازی مسیرهای آپوپتوز است. فعالیت‌بدنی منظم و استفاده از ترکیبات طبیعی، می‌توانند در کاهش اثرات سمی این فلز نقش داشته باشند. هدف از مطالعه‌ی حاضر، بررسی تأثیر تمرین هوازی همراه با مکمل کورکومین بر آپوپتوز کبدی موش‌های صحرایی در معرض Cd بود.
روش‌ها: در این مطالعه تجربی، 40 سر موش صحرایی نر به‌طور تصادفی به پنج گروه مساوی دریافت کادمیوم (Cd)، کادمیوم+دریافت کورکومین (Cd+Cu)، کادمیوم+تمرین (Cd+AT) و دریافت کادمیوم+کورکومین+تمرین (Cd+Cu+AT)) تقسیم شدند. گروه‌های دریافت‌کننده Cd، روزانه 5 میلی‌گرم به ازای هر کیلوگرم وزن بدن Cd دریافت کردند. تمرین هوازی شامل دویدن روی نوارگردان با شدت متوسط، به مدت 8 هفته و 5 جلسه در هفته اجرا شد. گروه‌های کورکومین نیز روزانه 160 میکرولیتر به ازای هر کیلوگرم وزن بدن کورکومین دریافت کردند. بیان ژن‌ها به روش RT-PCR اندازه‌گیری شد. مقایسه‌های بین گروهی با استفاده از آنالیز واریانس یک‌طرفه (ANOVA) و آزمون تعقیبی توکی انجام شد..
یافته‌ها: قرار گرفتن در معرض کادمیوم باعث افزایش معنی‌دار بیان BAX، نسبت BAX/BCL2 و سطح CASPASE-3، در کنار کاهش معنی‌دار BCL2، در مقایسه با C شد (0001/0 = P). بیان CASPASE-3 در گروه‌های Cd+Cu (023/0 = P) و Cd+AT (30/0 = P) نسبت به C افزایش معنی‌داری داشت. در مقابل BAX، نسبت BAX/BCL2 و CASPASE-3 در گروه‌های Cd+Cu (به ترتیب 0/013 = P، 0/0001 = P و 0/045 = PCd+AT (به ترتیب 0/003 = P، 0/0001 = P و 0/035 = P) و Cd+Cu+AT (0/0001 = P) نسبت به Cd کاهش معنی‌داری داشت. گروه Cd+Cu+AT کاهش معنی‌داری در CASPASE-3 نسبت به گروه‌ Cd+Cu (0/014 = P) و Cd+AT (0/019 = P) نشان داد. علاوه بر این، بیان BCL2 در گروه‌های Cd+Cu (0/013 = PCd+AT (0/006 = P) و Cd+Cu+AT (0/0001 = P) نسبت به Cd؛ و Cd+Cu+AT نسبت به گروه‌ Cd+Cu (0/010 = P) و Cd+AT (0/021 = P) افزایش معنی‌داری داشت.
نتیجه‌گیری: نتایج نشان‌دهنده‌ی نقش محافظتی تمرین هوازی و کورکومین در برابر سمیت Cd از طریق تنظیم مسیرهای مولکولی مرتبط با آپوپتوز است. ترکیب این دو مداخله، اثر هم‌افزایی در کاهش آسیب سلولی نشان داد و می‌تواند به عنوان رویکردی مؤثر در مقابله با آسیب‌های کبدی ناشی از فلزات سنگین پیشنهاد شود.

چکیده English

Background: Exposure to heavy metals such as cadmium (Cd) is a major contributor to liver damage, primarily through the activation of apoptotic pathways. Regular physical activity and the use of natural compounds may mitigate the toxic effects of Cd. This study aimed to investigate the effect of aerobic exercise combined with curcumin supplementation on liver apoptosis in Cd-exposed rats.
Materials and Methods: In this experimental study, 40 male Wistar rats were randomly assigned to five groups: Control, Cd, Cd + Curcumin (Cd+Cu), Cd + Aerobic Training (Cd+AT), and Cd + Curcumin + Aerobic Training (Cd+Cu+AT). The Cd groups received 5 mg/kg body weight of cadmium daily via drinking water. Aerobic training consisted of treadmill running at moderate intensity, five sessions per week for eight weeks. The curcumin groups received 160 µL/kg body weight of curcumin orally on a daily basis.
Results: The expression levels of apoptosis-related genes—BAX, BCL2, BAX/BCL2 ratio, and CASPASE-3 significantly increased in the Cd group compared to the control (p<0.0001). However, curcumin, aerobic exercise, and especially their combination significantly improved these apoptotic markers. Notably, BAX and CASPASE-3 expression decreased and BCL2 expression increased in the Cd+Cu+AT group compared to other Cd-exposed groups (p<0.01).
Discussion: These findings highlight the protective role of aerobic exercise and curcumin against Cd-induced hepatotoxicity through modulation of apoptotic molecular pathways. Their combination demonstrated a synergistic effect in reducing liver cell damage and may serve as an effective strategy against heavy metal-induced hepatic injury.
