Research Overview

We study how metabolism mechanistically controls cancer initiation and progression in the pancreas and stomach. We are specifically interested in how metabolism guides cell competition dynamics, environmental changes, and cell type-specific behaviors. Our work integrates tools from cell biology, biochemistry, transcriptomics, and metabolomics, using various systems, including preclinical models, primary cell cultures, and clinically relevant samples. Our current interests are briefly described below.

Tumorigenesis is dependent on changes within the local tissue environment. Additionally, metabolic conditions, including insulin resistance, obesity, and dyslipidemia, are often cancer risk factors. This project aims to 1) investigate how metabolism can control the persistence or restriction of mutant cells within a tissue and 2) determine how important metabolic pathways can be modulated by dietary intervention for cancer prevention.

How do metabolic changes in the environment alter cancer initiation?

We previously showed that NADPH-producing enzymes restrict precancer formation in the pancreas. Our lab continues to investigate the metabolic landscape of precancer, especially how it differs from established cancer. This project aims to identify the defining metabolic traits of the pre-tumor microenvironment.

What is the metabolic landscape of precancer?
