AREAS OF INTEREST

• Understanding mitochondrial function in human health and disease
• Mechanisms of control of mitochondrial DNA transcription

The long-term aim of the Dittenhafer-Reed lab is to study fundamental biochemical processes occurring in the mitochondria, a specialized compartment within cells. The mitochondria are often considered the powerhouse of the cell, converting nutrients from the food we eat into the chemical energy currency required to carry out all cellular functions. Mitochondrial dysfunction, analogous to batteries losing their charge, can result in a myriad of human diseases. The Dittenhafer-Reed lab aims to employ biochemistry, molecular biology and cell biology approaches to explore how processes within the mitochondria work in a healthy context to enable avenues for the treatment of conditions caused when mitochondria are not functioning properly.

More specifically, the Dittenhafer-Reed lab focuses on understanding the regulation of the expression of mitochondrial genes. Interestingly, mammalian cells contain genetic information (DNA) in two compartments, the nucleus and the mitochondria. These DNA molecules are a blueprint, carrying the instructions required for our cells to function. Through the process of transcription, genes, or specific pieces of the blueprint, are read and used to make proteins. These proteins are the machines that facilitate the billions of chemical reactions that occur each second in living organisms. Mitochondrial DNA carries the instructions to make some of the protein machinery required for energy production. The goal of this research is to investigate how the expression of mitochondrial DNA is regulated and how the mitochondria and nucleus communicate, specifically to meet varying energetic demands of a cell.
