Research Focus

Our team studies mitochondrial function using genetic and biochemical approaches. We focus on two key components of the mitochondrial oxidative phosphorylation machinery, cytochrome c oxidase (COX) and the small electron carrier cytochrome c (Cytc). COX is the terminal enzyme of the mitochondrial respiratory chain, “burns” the oxygen we breathe to water, and pumps protons across the inner mitochondrial membrane generating the mitochondrial membrane potential, which is utilized by ATP synthase to produce energy in the form of ATP. Cytc has two distinct functions: it delivers electrons to COX, but it also participates in programmed cell death (apoptosis).

The overall goal of our work is to understand the regulation of COX and Cytc in normal and disease conditions. This regulation in turn affects energy production, free radical generation, and apoptosis. Research topics of the Hüttemann group under investigation include 1) cell signaling pathways that act on COX and Cytc, which pathways are often dysregulated in human diseases; 2) lung cancer; 3) neurodegenerative diseases; 4) gene regulation of COX subunit isoforms; and 5) novel strategies to boost mitochondrial function as a future treatment for diseases that manifest themselves in a lack of energy and increased cell death.
