Abstract

Over one million research articles have been published about cancer, but yet our understanding about cancer is undeniably little. We are yet to understand some of the most basic questions such as: (1) why some cancers such as pancreatic or liver cancers are so deadly while other cancers such as basal cell carcinoma or thyroid cancer are rarely life-threatening? or (2) why some cancers are highly drug-resistant while other cancers are not? In this talk, I present some of our recent discoveries made through mining omic data of large numbers of cancer tissue samples. Our analyses strongly suggest that all cancer tissue cells have high levels of Fenton reactions, which continuously produce OH-, to which the affected cells respond fiercely to maintain the pH stability as changes in the intracellular pH would have profound impacts on the viability of the cells. As a result, cells mobilize a variety of ways to accomplish this at very high costs. Some of the long-standing open questions and basic questions like the above can be answered naturally using our new model.
