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 …
