As mitochondria have crucial roles in metabolism and signaling, their structure and function must be continuously monitored and rapidly adjusted to meet cellular demands. Critical to this regulation ...
Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the metabolism of the cell, they also play a key role in the integration of signals ...
In eukaryotic cells, mitochondria and the endoplasmic reticulum (ER) form close contacts at mitochondria-associated ER membranes (MAMs), which are involved in diverse cellular processes. The outer ...
In a recent study published in Nature Communications, researchers at Karolinska Institutet report that the molecular ...
Many of us remember from high school biology class that mitochondria are the cell’s “power plants.” These small kidney-bean-shaped structures are what convert nutrients from food into ATP — the cell’s ...
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...
Researchers at the University of Jyväskylä have found that herpesvirus infection modifies the structure and normal function of the mitochondria in the host cell. The new information will help to ...
Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria, the 'powerhouses' of our cells, allows us to make the fuel we need from sugars, a ...
Scientists led by a team at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out how a molecular machine found in mitochondria—the “powerhouses” of ...
