Focus on Cellular Signalling Research
Leeds, Dorothy T
Cell signalling is the communication inside a cell or with its environment. It plays an important role in cellular growth, survival and apoptosis. For instance, the growth of a cell requires production of certain proteins. The genes that encode these proteins are located in DNA inside the nucleus while the initial signal for cellular growth may come from outside the cell. To induce the expression of these genes, the external signal must pass t...
