Effect Of Long Term Rapamycin Treatment On Mtor Signalling Network In Colon And Liver Of C57bl/6 Mice, John Sorge Jan 2014

Effect Of Long Term Rapamycin Treatment On Mtor Signalling Network In Colon And Liver Of C57bl/6 Mice, John Sorge

Wayne State University Theses

Many studies have investigated the effects of rapamycin on aging and cancer. However, the effects of long-term rapamycin supplementation on a cancer model have not been performed. This is the first study that investigates the effects of long-term supplementation of rapamycin in a cancer model. ACF analysis of colon tissues in mice showed no significant difference between controls and those supplemented with rapamycin. Factors such as energy balance, cellular environment, PI3K/Akt/mTOR pathway, and more have been assessed in this study. The duration of rapamycin supplementation seems to play an important role in the protection against cancer. Ultimately, this study suggests …

Effects Of Altering The Peroxisomal Redox State In Models Of Degenerative Disease, Courtney Rose Giordano Jan 2014

Effects Of Altering The Peroxisomal Redox State In Models Of Degenerative Disease, Courtney Rose Giordano

Wayne State University Dissertations

Peroxisomes are important regulators of cellular redox balance and function as a signaling platform to regulate anti-aging metabolic and communication networks. In addition the organelle has emerged as a major player in maintaining cellular ROS at an optimal level. At such levels, these ROS are involved in initiation of signaling cascades and that produce an array of anti-aging and disease processes. However, as cells age over time, ROS amass within the peroxisome and elsewhere in the cell. This leads to an imbalance in oxidative homeostasis and results in compromised signaling networks. The goal of this dissertation was to treat disease …
