Background and Purpose: Lung cancer is one of the most important causes of global mortality and oxidative stress and inflammatory factors play an important role in its occurrence and development. Probably regular exercise along with taking anti-inflammatory supplements can be effective in improving lung cancer through reducing oxidative stress and inflammatory factors, though, this is not well known and needs to be further investigated. Therefore, we aimed to investigate the effect of 12 weeks of swimming training and royal jelly consumption on the expression of JNK and activator protein 1 (AP-1) genes in mice with Benzo[a]pyrene -induced lung cancer.
Materials and Methods: In this experimental study, 36 male Balb/c mice (age, 8 to 10 weeks; weight, 18 to 25 g) were randomly assigned to 6 groups: healthy control (n=6), sham (n=6), and experimental (n=24). Thereafter, cancer was induced by injection of 100 mg/kg body weight of benzopyrene, and the mice in the experimental group were divided into four subgroups of control with lung cancer (n=6), swimming training (n=6), royal jelly (n=6), and training + royal jelly (n=6). Swimming training was performed three times a week for 12 weeks. Royal jelly was also injected intraperitoneally at a dose of 100 mg/kg of body weight daily for 12 weeks. Forty-eight hours after the last training session, JNK and AP-1 gene expression were measured using Real-Time PCR. To analyze the data, a one-way analysis of variance (ANOVA) test with Tukey post-hoc tests and two-way ANOVA with Bonferroni post-hoc tests were used.
Results: Data analyses revealed that the expression of JNK and AP-1 genes in the lung cancer group was significantly increased compared to the healthy control group (p=0.001). Although the expression of JNK and AP-1genes were lower in the royal jelly group compared to the control cancer group (p=0.044, p=0.007, respectively), no significant differences were observed in the expression of these two genes between swimming training group and control cancer group (p=0.056, p=0.18, respectively). Finally, our result indicated that training + royal jelly group had the greatest decrease in expression of JNK and AP-1genes compared to the control cancer group (both p=0.001).
Conclusion: According to the study results, it seems that swimming training along with the consumption of royal jelly has more inhibitory and protective effects on the expression of JNK and AP-1 genes in lung tissue compared to either of these interventions in mice with lung cancer. To generalize the results to human, further studies on human subjects are warranted.
