For example, in three meta-analyses regarding the relationship between adiponectin levels and breast cancer risk published in the last two years, one suggested that low circulating adiponectin levels were associated with an increased breast cancer risk[15], whereas the other two (including our own meta-analysis) showed that high adiponectin levels might decrease breast cancer risk, specifically in postmenopausal women[16,17]. Here, ADIPOQ is linked to breast cancer.
