RESUMO

Objective. Tai Chi Chuan (TCC) is a form of aerobic exercise that may be an effective therapy for improving psychosomatic capacity among breast cancer survivors. This meta-analysis analyzed the available randomized controlled trials (RCTs) on the effects of TCC in relieving treatment-related side effects and quality of life in women with breast cancer. Methods. RCTs were searched in PubMed, Embase, Web of Science, and Cochrane Library through April 2014. Data were analyzed on pathology (pain, interleukin-6, and insulin-like growth factor 1), physical capacity (handgrip, limb physical fitness, and BMI), and well-being (physical, social, emotional, and general quality of life). Results. Nine RCTs, including a total of 322 breast cancer patients, were examined. Compared with control therapies, the pooled results suggested that TCC showed significant effects in improving handgrip dynamometer strength, limb elbow flexion (elbow extension, abduction, and horizontal adduction). No significant differences were observed in pain, interleukin-6, insulin-like growth factor, BMI, physical well-being, social or emotional well-being, or general health-related quality of life. Conclusion. The short-term effects of TCC may have potential benefits in upper limb functional mobility in patients with breast cancer. Additional randomized controlled trials with longer follow-up are needed to provide more reliable evidence.

RESUMO

MiR-130a has been demonstrated to play important roles in many types of cancers. Nevertheless, its biological function in breast cancer remains largely unknown. In this study, we found that the expression level of miR-130a was down-regulated in breast cancer tissues and cells. Overexpression of miR-130a was able to inhibit cell proliferation, invasion and migration in MCF7 and MDA-MB-435 cells. With the bioinformatics analysis, we further identified that RAB5A was a directly target of miR-130a, and its mRNA and protein level was negatively regulated by miR-130a. Immunohistochemistry verified RAB5A was upregulated in breast cancer tissues. Therefore, the data reported here demonstrate that miR-130a is an important tumor suppressor in breast cancer, and imply that miR-130a/RAB5A axis have potential as therapeutic targets for breast cancer.
