Receptors are generally transmembrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

A single molecular switch is essential for blood stem ... cell activation and its integration with known signaling pathways that drive stem cell self-renewal and survival. It also clarified ...

and those stem cells eventually recover the intestine and turn back to normal cells.” Scientists have been looking for a long time for the “switch” that turns regular intestinal cells back into ...

“This study is important because it looks at the types of cells that regenerate broken bones, the skeletal stem cells, and how they, in turn, are affected by aging.” To investigate the molecular ...
