Overview
Signaling refers to the intricate process of information transmission within biological systems, enabling cells to respond to their environment and communicate with each other. This complex process involves a series of molecular interactions, starting with an active signal and culminating in a cellular response. Signaling plays a crucial role in various biological processes, including development, growth, and disease. The mitogen-activated protein kinase (MAPK) pathway, the phosphatidylinositol 3-kinase (PI3K) pathway, and the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway are key signaling pathways. The epidermal growth factor receptor (EGFR) is a key player in signaling pathways, and its dysregulation has been implicated in various diseases, including cancer.
