Mitochondrial Structure And Function As A Therapeutic Target In Malignant Mesothelioma, Brian Cunniff

Graduate College Dissertations and Theses

Malignant mesothelioma (MM) is a rare tumor associated with occupational exposure to asbestos with no effective treatment regime. Evaluation of mitochondrial function in human MM cell lines revealed a common tumor phenotype: in comparison to immortalized or primary human mesothelial cells, MM tumor cells displayed a more oxidized mitochondrial environment, increased expression of mitochondrial antioxidant enzymes, and altered mitochondrial metabolism. Earlier work by our laboratory indicated that increases in mitochondrial reactive oxygen species (mROS) in MM cell lines supports expression of FOXM1, an oncogenic transcription factor that contributes to increased cell proliferation and chemoresistance. These studies sought to investigate targeting …
