Hypothesis
Notch, IL-1 and leptin crosstalk outcome (NILCO) plays an essential role in the regulation of leptin-mediated induction of proliferation/migration and expression of pro-angiogenic molecules in breast cancer.
Conclusion
Leptin induction of proliferation/migration and upregulation of VEGF/VEGFR-2 in breast cancer cells are related to an intact Notch signaling axis.
Supporting Evidence
- Leptin up-regulated Notch1-4 and pro-angiogenic factors in breast cancer cells.
- Leptin-induced effects on cell proliferation and migration were abrogated by Notch inhibition.
- IL-1 signaling was found to mediate leptin's effects on Notch and VEGF expression.
Takeaway
Leptin helps breast cancer cells grow and spread by working with other signals in the body, like Notch and IL-1.
Methodology
The study used mouse breast cancer cell lines to investigate the effects of leptin on Notch signaling and pro-angiogenic factors.
