The modifications of PGC-1𝛼 induce the change of the carcinogenesis and tumor growth and lead to increased antioxidant enzymes. The present study aimed to determine the cross talk between PGC1-α mRNA expression, tumor volume growth, and total antioxidant capacity in breast cancer model mice, followed by discontinuous aerobic exercise and vitamin D. In the present study, 40 female NMRI mice were randomly assigned into five equal groups (n=8): healthy control group (H.C), cancer control group (Ca.C), cancer with the vitamin D group (U.Ca.VD), cancer exercise training group (Ca. Ex), and cancer exercise training with the vitamin D group (Ca.Ex.VD). As the results indicate, the bodyweight of cancer groups (p=0.041, F=3.61) and the tumor growth rate significantly reduced compared to the H.C group. The results indicated that the PGC-1α mRNA expression and TAC (p=0.013, F=5.16) change significantly different between the study groups. Besides, based on the results, a significant positive correlation was observed between PGC1-α and tumor volume growth among the groups, whereas a negative relationship exists between PGC1-α and TAC and among TAC and tumor volume growth only in the Ca. Ex.VD group. The correlation between the variables confirms using vitamin D treatment with the implementation of discontinuous aerobic exercise, as a synergistic effect, improves the total antioxidant capacity and is effective in controlling tumor growth. We recommend that further studies be done on exercise training along with supplementation intake synergistic.

What is already known on this subject?

PGC-1α promotes breast cancer metastasis and confers bioenergetics flexibility against metabolic drugs but with the intervention of exercise training and vitamin D, a different issue is raised for which a definite answer has not been given yet.


What this study adds?

We know that taking vitamin D supplementation along with implementation of discontinuous aerobic exercise as a synergistic effect improves the total antioxidant capacity and is effective in controlling tumor growth.
