Mammalian mitochondrion

Mammalian mitochondria are double-membrane-bound organelles that serve as the primary site for cellular energy production through oxidative phosphorylation and the citric acid cycle [1]. Beyond their role as the “powerhouse of the cell,” they are central regulators of programmed cell death (apoptosis), calcium signaling, and the synthesis of essential metabolic precursors like heme and iron-sulfur clusters [1, 2]. Mitochondrial dysfunction, characterized by impaired ATP production and excessive reactive oxygen species (ROS) generation, is a hallmark of numerous pathological conditions, including primary mitochondrial diseases, neurodegenerative disorders, and metabolic syndromes [2]. Pharmacological targeting of mitochondria involves diverse strategies, such as the use of antioxidants like MitoQ to neutralize ROS, or metabolic modulators like Metformin that influence the electron transport chain [3, 4]. However, therapeutic intervention is complicated by the organelle's complex structure and the risk of disrupting vital metabolic pathways in healthy cells, which can lead to severe side effects like lactic acidosis [1, 3].
