The transmission of an extracellular signal from the surface of the cell to the nucleus by a relay of protein-protein and protein-ligand interactions.

细胞外的信号通过蛋白与蛋白和蛋白与配体的作用由细胞表面传送到细胞核。

If the load resistor was connected directly across the voltmeter input terminals, the current through the relay contacts would cause a voltage drop and the measured cell voltage would be in error.

如果负载电阻被直接连接到伏特计的输入端子，通过继电器触点的电流会产生电压降，测得的电池电压将存在误差。

The hope was that this would restore brain cell activity in the thalamus, a relay station that integrates input from many parts of the brain, helping make consciousness possible.

The reason the Swiss Army knife approach could prove more effective is that many of the growth-promoting proteins involved in cancer are kinases, proteins that relay signals from one part of the cell to another.
