Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is ...

Gene regulation in our cells—the decision on which proteins are produced for the various processes of the cell—is strictly regulated. It has long been assumed that this regulation deteriorates with ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

A new review highlights the pivotal role of LSD1 (lysine-specific demethylase 1) in regulating critical cellular processes and its implications for human diseases. This article sheds light on how post ...

A molecular geneticist at Montana State University has discovered a cellular process once believed impossible by scientists—the creation of the amino acid cysteine within a living cell when the cell's ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Caspases are a family of proteolytic enzymes that play a central role in apoptosis, the regulated process of programmed cell death essential for development, homeostasis and the clearance of damaged ...

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission. Cyanobacteria, an ...

To study biological processes, scientists often take snapshots of the molecules in cells, such as proteins and nucleotides, at specific points in time. In spatial biology, they can leverage molecular ...

Cellular senescence is a biological process observed in eukaryotic and some prokaryotic cells 1,2. It refers to the permanent arrest of the cell cycle in response to exogenous or endogenous stimuli, ...
