Redox and metabolic pathways

Redox and metabolic pathways encompass the integrated network of biochemical reactions responsible for energy conversion and the maintenance of cellular oxidative balance. These pathways, including glycolysis, the citric acid cycle, and oxidative phosphorylation, are fundamental to all cellular life and are tightly regulated to ensure homeostasis (Source: Nature Reviews Molecular Cell Biology, 2018). In various pathologies, such as cancer, cells undergo metabolic reprogramming to support rapid proliferation and survival under stress, often by altering redox signaling (Source: Cell Metabolism, 2020). While the term refers to a broad biological system rather than a single protein, many specific enzymes within these pathways serve as critical therapeutic targets. Drugs interacting with these systems aim to exploit metabolic vulnerabilities or restore redox equilibrium to treat conditions ranging from metabolic disorders to malignancy (Source: Pharmacological Reviews, 2017). For instance, targeting the redox balance can sensitize tumor cells to chemotherapy or radiation. Additionally, metabolic modulators like metformin are widely used to manage systemic glucose levels in diabetic patients. Understanding the crosstalk between these pathways is essential for developing precision medicines that minimize off-target effects on healthy tissues.
