Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's functional units. Researchers at the Paul Scherrer Institute PSI and the Department ...

Tooth root development relies on precise coordination of cellular signals, yet the underlying mechanisms remain unclear. Researchers have uncovered how two proteins, Gli2 and Gli3, work together to ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...
