Research Snapshot: New aging-related molecular pathway discovered
A collaborative project between the labs of Maulik Patel and Kris Burkewitz has identified a new molecular pathway that plays a key role in the ability of cells to sense and respond to stressed mitochondria. Read MoreJun 23, 2022

Mitochondrial stress and hypertension
Oxidative stress and toxic products called isolevuglandins in mitochondria play a role in endothelial dysfunction and hypertension — and getting rid of them with a special “scavenger” molecule has therapeutic potential. Read MoreJan 12, 2021

Transporter mutation alters cell energy
A disease-associated mutation in a transporter protein causes cells to increase energy production, as if they are starving, Vanderbilt researchers have discovered. Read MoreFeb 20, 2020

Mitochondrial mutations and disease
New findings suggest that oxidative stress damages mitochondrial DNA, and they link this damage to a disease state. Read MoreFeb 22, 2018

Discovery of male-harming DNA mutation reinforces ‘mother’s curse’ hypothesis
There is new evidence that the "mother’s curse" – the possibility that moms may transmit genes to their children that harm their sons but not their daughters – holds true in animals. Read MoreAug 2, 2016

When mitochondrial genes act up
A team of Vanderbilt scientists have identified some of the methods that mutant mitochondrial DNA use to circumvent the molecular mechanisms that cells use to regulate mitochondrial activity. Read MoreJul 12, 2016

Study sheds light on a ‘guardian’ protein of brain function
Mitochondria not only are the cell’s main power producers, they are also the chief cooks and bottle washers. Read MoreFeb 19, 2015
