Abstract

Obesity is associated with the higher risk of breast cancer in postmenopausal women. The leptin signaling pathway is recognized to primarily regulate energy balance and associated with breast cancer. Furthermore, the estrogen signaling pathway plays a critical role in breast carcinogenesis. In this review, we discuss how obesity is linked to breast cancer via cross-talk of leptin and estrogen pathways.

Fig.1  The model of molecular link between breast cancer and obesity.
We propose that one or more signaling components acting downstream of leptin receptor may interact with ERα, thereby mediating the direct cross-talk of leptin and estrogen signaling pathways. Identification of these components and elucidation of the biochemical basis will lead to the better understanding of how obesity is associated with breast carcinogenesis.
