What Is the Relevance of Murburn Concept in Thalassemia and Respiratory Diseases?

Murburn concept is a novel perspective for understanding cellular function, deeming cells as simple chemical engines (SCE) that are powered by redox reactions initiated by effective charge separation (ECS). The 1-electron active diffusible reactive (oxygen) species, or DR(O)S, equilibriums involved in these processes are also crucial for homeostasis, coherently networking cells, and rendering electromechanical functions of sensing and responding to stimuli. This perspective presents the true physiological function of oxygen, which is to enable ECS and the generation of DR(O)S. Therefore, DR(O)S must now to be seen as the quintessential elixir of life, although they might have undesired effects (i.e., the traditionally perceived oxidative stress) when present in the wrong amounts, places and times. We also elaborated that tetrameric hemoglobin (Hb) is actually an ATP-synthesizing murzyme (an enzyme working via murburn concept) and postulated that several post-translational modifications (such as glycation) on Hb could result from murburn activity. Murburn perspective has also enabled the establishment of a facile rationale explaining the sustenance of erythrocytes for 3–4 months, despite their lacking nucleus or mitochondria (to coordinate their various functions and mass-produce ATP, respectively). Although thalassemia has its roots in genetic causation, the new awareness of the mechanistic roles of oxygen-hemoglobin-erythrocyte trio significantly impacts our approaches to interpreting research data and devising therapies for this malady. These insights are also relevant in other clinical manifestations that involve respiratory distress (such as asthma, lung cancer, COVID-19 and pneumonia) and mitochondrial diseases. Herein, these contexts and developments are briefly discussed.
