Metformin (MET) is increasingly implicated in reducing the incidence of multiple cancer types in patients with diabetes. However, similar effects of MET in non-diabetic women with endometrial cancer (EC) remain unknown. In a pilot study, obese non-diabetic women diagnosed with type 1, grade 1/2 EC, and consenting to participate were randomly assigned to receive MET or no MET (control (CON)) during the pre-surgical window between diagnosis and hysterectomy.

To examine the role of ME1 in tumor genesis of the gastrointestinal tract, we crossed mice having augmented intestinal epithelial expression of ME1 (ME1-Tg mice) with Apc mice to obtain male Apc/ME1-Tg mice. ME1 protein levels were significantly greater within gut epithelium and adenomas of male Apc/ME1-Tg than Apc mice.

Objective: To evaluate the association between Notch-1 signaling activation and P resistance in the progression of endometriosis.
Design: Case control study; archived formalin-fixed, paraffin-embedded tissues.
