Signaling pathway network

A **signaling pathway network** refers to the dynamic set of interconnected signaling pathways—composed of proteins, receptors, effectors, and regulatory molecules—within a cell that detect, integrate, process, and transmit extracellular and intracellular signals[3][4][5][6]. These networks enable coordinated cellular responses to stimuli, including changes in gene expression, metabolism, growth, differentiation, or apoptosis[4][5]. Network topology modulates how cells interpret and respond to signals, integrating feedback, filtering noise, and determining cellular fate or disease states[3][6][8]. Unlike specific proteins or receptors, signaling pathway networks comprise many distinct molecules (receptors, kinases, transcription factors, etc.) and their interrelationships, making them non-canonical therapeutic targets but essential for understanding drug action, resistance, and disease mechanisms[10].
