Roles of caloric restriction, ketogenic diet and intermittent fasting during initiation, progression and metastasis of cancer in animal models: a systematic review and meta-analysis.

Background: The role of dietary restriction regimens such as caloric restriction, ketogenic diet and intermittent fasting in development of cancers has been detected via abundant preclinical experiments. However, the conclusions are controversial. We aim to review the relevant animal studies systematically and provide assistance for further clinical studies.

Searching for candidate microRNA biomarkers in detection of breast cancer: a meta-analysis.

Background: MicroRNAs (miRNAs) are recognized as potential biomarkers for detection of breast cancer. Many experiments have been done to explore the aberrant expression of circulating miRNAs in breast cancer patients. However, an overwhelming number of miRNAs are identified and some expression characteristics are inconsistent between studies.
