Anti-Insulin Resistance Treatments Suppress Her2+ Breast Cancer Growth Via Altering Metabolism, Ping-Chieh Chou
Anti-Insulin Resistance Treatments Suppress Her2+ Breast Cancer Growth Via Altering Metabolism, Ping-Chieh Chou
Dissertations & Theses (Open Access)
Epidemiological studies have identified that type 2 diabetes mellitus (DM2) is a significant risk factor for carcinogenesis and cancer death, including breast cancer. Our previous finding in patients showed that anti-insulin resistance treatments are associated with improved HER2+ breast cancer survival of diabetic women. However, there were no transgenic mouse models to study the correlation and explain the detailed mechanism. We generated a mouse model of HER2+ breast cancer with DM2 by crossing leptin receptor point mutation (Lepr db/+) and MMTV-ErbB2 (neu) mice. The MMTV-ErbB2/Lepr db/db mice had a poor survival rate compared …
Diabetes And Obesity Induce Transcriptomic And Metabolomic Changes Enhancing Pancreatic Cancer Aggressiveness, Guermarie Velázquez Torres
Diabetes And Obesity Induce Transcriptomic And Metabolomic Changes Enhancing Pancreatic Cancer Aggressiveness, Guermarie Velázquez Torres
Dissertations & Theses (Open Access)
Pancreatic cancer is one of the most aggressive types of cancer, with poor prognosis that lacks effective diagnostic markers and therapies. It is expected that in 2014 the incidence and the mortality of pancreatic cancer in the United States will be 46,420 and 39,590 respectively. Diabetes and obesity are modifiable risk factors associated with accelerated pancreatic carcinogenesis and tumor progression, but the biological mechanisms are not completely understood. The purpose of this study is to demonstrate direct evidence for the mechanisms mediating these epidemiologic phenomena. Our hypothesis is that obesity and diabetes mellitus type 2 (DM2) accelerate pancreatic cancer and …
