Metabolism Reprogramming In Hexavalent Chromium-Induced Human Lung Carcinogenesis, James Tate Fortin Wise

Theses and Dissertations--Pharmacology and Nutritional Sciences

Hexavalent chromium, Cr(VI), is an established human carcinogen that is a worldwide environmental health concern. It is well understood that reactive oxygen species, genomic instability, and DNA damage repair deficiency are important contributors to Cr(VI)-induced carcinogenesis. After decades of research some cancer hallmarks remain understudied for the mechanism of Cr(VI) carcinogenesis. Dysregulated cellular energetics have been established as a hallmark of cancer. Energy pathways that become dysregulated in cancer include mitochondrial respiration, lipogenesis, pentose phosphate pathway, one carbon metabolism, and increased anaerobic glycolysis in the presence of oxygen or ‘Warburg effect’.

To investigate metabolism changes in Cr(VI) carcinogenesis, we exposed …

Studies Of Oxidative Damage, Brain Proteome, And Neurochemical Metabolites In Cognitive And Neurodegenerative Disorders: (1) Chemotherapy-Induced Cognitive Impairment; (2) Parkinson Disease Rat Model, Xiaojia Ren

Theses and Dissertations--Chemistry

The rate of cancer patients is increasing as the development of science and technology. Twenty million cancer survivors are estimated living in the United States by 2025. However, many cancer survivors show cognitive dysfunction, negatively affecting the quality of life. These cognitive impairments are recognized as chemotherapy-induced cognitive impairment (CICI), also called "chemo brain" by cancer survivors, including the diminished ability of memory and learning, hard to concentrate and focus, as well as diminution of executive function and processing speed. The etiologies and pathologies of CICI are complicated, especially in most cases the anti-cancer drug cannot cross the blood-brain barrier …
