Multiple Endogenous Signaling Pathways

Multiple Endogenous Signaling Pathways refers to the integrated networks of molecular interactions, such as the MAPK/ERK or PI3K/Akt pathways, that transmit external stimuli to elicit specific cellular responses (National Human Genome Research Institute, 2024). These pathways are essential for maintaining homeostasis and regulating fundamental biological processes including growth, metabolism, and apoptosis (Cooper, 2000). Because this term represents a broad category of biological activity rather than a discrete molecular entity like a receptor or enzyme, it is not classified as a specific therapeutic target (Santos et al., 2017). In drug development, specificity is required to ensure that a molecule interacts with a defined target to produce a predictable clinical outcome (Overington et al., 2006). Consequently, while multiple pathways may be dysregulated in complex diseases like cancer or chronic inflammation, therapeutic intervention focuses on modulating specific components within these networks to improve efficacy and reduce systemic toxicity.
