How five-carbon (C5) metabolism affects human health

Elucidation of the chemical and biological roles of five-carbon metabolism

NIH-funded research University of Tennessee Knoxville · NIH-11249659

This work looks at how tiny C5 molecules made by the isoprenoid pathway influence cell health and conditions like dementia, adrenal disorders, and heart disease.

What this research studies

Researchers will create chemical probes and genetic tools to track and manipulate the two central C5 metabolites (IPP and DMAPP) inside human cells and laboratory models. They will study how changes in these molecules affect cholesterol, glycoprotein production, steroid hormone signaling, and mitochondrial function. The team will focus on the enzyme IPPI that helps balance IPP and DMAPP and test how altering it changes cell biology linked to diseases. Results will be used to point to new disease mechanisms and possible targets for future therapies.

Who could benefit from this research

Good fit: People with disorders connected to isoprenoid biology—for example certain forms of dementia (including Alzheimer-type dementia), adrenal disorders like Addison-related syndromes, or metabolic/mitochondrial conditions—would be most relevant to this research.

Not a fit: Patients with conditions unrelated to isoprenoid pathways (for example isolated orthopedic injuries or acute infections) are unlikely to see direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could reveal new biological targets and diagnostic clues that lead to treatments for conditions tied to isoprenoid metabolism.

How similar studies have performed: This is a relatively novel approach because few chemical probes exist for IPP and DMAPP, although related isoprenoid research (such as work on cholesterol synthesis) has successfully produced widely used drugs like statins.
