| الوصف: | Weight gain and/or obesity are now considered to be risk factors for the development of postmenopausal breast cancer. Thus, weight loss and/or maintenance resulting from calorie restriction (CR) is recommended however success rates are infrequent. Metformin (MET) is a safe and effective treatment for type 2 diabetes mellitus and its use has been linked to reduced breast cancer incidence and mortality in comparison to other forms of diabetes treatments. Interestingly, MET's mechanism of action is considered to be similar to CR. The goal of the present investigation was to directly compare the effect of CR implemented at midlife with the administration of metformin on the development of mammary tumors (MT) in a relevant mouse model. Further, since these interventions would likely be used by obese women we studied both lean and obese mice. Female MMTV-TGF-α mice which develop MTs in the second year of life were fed ad libitum (AL) either a low fat (LF) (10.2% by calories) diet or a moderately high fat (HF) (33.5% by calories) diet from 10 until 30 weeks of age. At 30 weeks the mice on each diet were divided into AL, MET (250 mg/kg/bw/day) or CR (25% reduction in calories) subgroups and then followed until 90 weeks of age. HF-AL and HF-Met mice were significantly heavier that the other 4 groups whose weights were similar. The survival curves had an overall P value of P Supported by NIH-NCI CA157012, The Hormel Foundation and Paint the Town Pink. Citation Format: Cleary MP, Mizuno NK, Yang D-Q, Liao J, Grossmann ME.
