Physiological adaptation pathways

Physiological adaptation pathways refer to the integrated network of biological processes that allow an organism or cell to maintain internal stability, or homeostasis, in the face of environmental changes or internal stressors (StatPearls, 2023). These pathways encompass a wide array of mechanisms, including the hypoxia-inducible factor (HIF) signaling pathway, the heat shock response, and the integrated stress response, which collectively ensure survival under conditions such as nutrient deprivation or oxidative stress (Nature Reviews Molecular Cell Biology, 2020). In various disease states, particularly oncology, these pathways are often hijacked by cells to promote survival in hostile microenvironments and to develop resistance against therapeutic interventions (Journal of Clinical Investigation, 2018). However, 'Physiological adaptation pathways' is a broad conceptual category rather than a specific molecular target like a single receptor or enzyme (NIH, 2022). Consequently, it is not considered a discrete therapeutic target; instead, drug discovery efforts focus on modulating specific proteins or nodes within these pathways to achieve clinical efficacy.
