- Description
- Unopposed oestrogen results in approximately 80% of all the endometrial cancer patients. The relationship between unopposed oestrogen and endometrial cancer was indicated by the increase in the number of endometrial cancer cases due to the widespread use of oestrogen replacement therapy. Approximately 30% of the endometrial cancer patients have mutations in the Wnt signalling pathway. How the unbalanced ratios of ovarian hormones and the mutations in Wnt signalling pathway interact to cause endometrial cancer is currently unclear. To study this, we have developed a uterine epithelial cell-specific inducible cre mouse model and used 3D in vitro culture of human endometrial cancer cell lines. We showed that activating mutations in the Wnt signalling pathway for a prolonged period leads to endometrial hyperplasia but not endometrial cancer. Interestingly, unopposed oestrogen and activating mutations in Wnt signalling together drive the progression of endometrial hyperplasia to endometrial cancer. We have provided evidence that progesterone can be used as a targeted therapy against endometrial cancer cases presented with the activating mutations in Wnt signalling pathway.
