Cell signalling pathways are central to maintaining cellular homeostasis and regulating essential functions such as proliferation, apoptosis, and repair. In both cancer and neurodegenerative diseases, ...
Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth factors, ...
The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns. Scientists at St. Jude Children's ...
In a recently published review, a research team led by MedUni Vienna has highlighted a promising new approach to drug discovery. The focus is on the targeted modulation of certain intracellular ...
Biophysicist Susy Kohout explores how cells respond to electrical cues, shedding light on the connection between cell ...
Mitochondria are specialized structures within cells that are primarily responsible for energy production but that also play a key role in how cells respond and adapt to stress. When their function ...

Calcium is widely known for its role in maintaining strong bones and teeth, but it is also one of the body's most important cellular messengers. Calcium signals help regulate muscle contraction, ...
As a flower bud grows and gains more cells, the random spikes and dips in any one cell matter less to the overall pattern.
