Background: This study aimed to examine the effect of yoga training combined with vitamin D supplementation on the expression of survival-related genes in leukocytes and psycho-physical status in breast cancer survivors. Methods: Thirty breast cancer survivor women (age, 48 ± 8 yrs) were randomly assigned into three groups: high dose (4000 IU) of vitamin D supplementation (HD) (n = 10); yoga training with a high dose of vitamin D (Y + HD); (n = 10); yoga training with a low dose (2000 IU) of vitamin D (Y + LD) (n = 10). Participants performed the Hatha yoga style twice a week. Blood samples and a battery of psychological and physical tests were taken before and after the completion of interventions. Expression of p53, NF-κB, Bcl2, and Bax genes was measured in leukocytes. Results: Body fat percentage (ηp2 = 0.36), shoulder flexibility (ηp2 = 0.38), Rockport walk tests (ηp2 = 0.49), and anxiety (ηp2 = 0.52) were significantly improved in both the Y + HD and Y + LD groups compared to the HD group (p < 0.05). P53 was significantly over-expressed in the Y + HD group while Bcl2 upregulated in both the Y + HD and Y + LD groups. NF-κB and Bax expression downregulated in all groups but were not statistically significant. Conclusion: yoga training combined with low and high doses of VD improved physical fitness and psychological measures while only in combination with a high dose of VD positively modified the leukocytes cell survival-related gene expression.
