Abstract
Cell signal transduction is essential for human life. Signal transduction pathways participate in all cell life activities, such as cell metabolism, cell division, cell differentiation, cell functional activities, and cell death. During cell metabolism, cells ingest and metabolize nutrients that provide energy. During cell division, DNA is replicated, and signaling pathways regulate the cell cycle, allowing for cell division and proliferation. During cell differentiation, gene products in cells are selectively expressed, thereby allowing cells to differentiate into mature cells with specific functions. During cell functional activities, cells release neurotransmitters or biochemicals, leading to contraction or relaxation of muscle cells, cytoskeletal formation, or remodeling. Cell death is the final event of the cell life cycle, which can occur in a local and a certain number of groups in order to maintain the overall benefit.
