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

The P13K/Akt pathway is a critical mediator of growth factor signaling involving many cellular functions. The deregulation of this pathway has been shown to be involved in the development of various cancers. One of the main targets of this pathway is FoxO3a, a transcription factor whose target genes are involved in important cellular processes such as apoptosis, cell cycle control, and glucose metabolism. FoxO3a is regulated by various post translational modifications including acetylation, ubiquitination and phosphorylation. The transcription factor is directly phosphorylated by Akt on 3 residues: Threonine 32, Serine 253 and Serine 315. Phosphorylation by Akt generates binding sites …
