Global cellular pathways

Global cellular pathways refer to the integrated network of biochemical reactions and signaling cascades that govern cellular behavior, including growth, metabolism, and response to external stimuli (NCBI, 2023). This term does not describe a single molecular entity but rather the collective interactions of proteins, nucleic acids, and metabolites within a biological system. In a therapeutic context, drugs typically target specific components within these pathways—such as receptors or enzymes—to modulate the overall pathway activity (Nature Reviews Molecular Cell Biology, 2021). Dysregulation of these global networks is a hallmark of complex diseases like cancer and diabetes, where multiple pathways are often simultaneously affected. Because Global cellular pathways encompasses all cellular processes, it is considered too broad to be a specific therapeutic target for drug development. Instead, researchers focus on individual nodes or specific signaling axes to achieve therapeutic efficacy while minimizing systemic toxicity. Understanding these pathways as a whole is essential for systems biology and predicting drug-drug interactions or polypharmacology. However, for the purposes of target identification, this entry represents a category of biological processes rather than a discrete druggable molecule.

Not applicable as this is a collective term for all cellular processes rather than a specific molecular target.
