Cancer isn’t bad genes or bad luck—it’s damaged mitochondria.
• Energy Production Shift: Damaged mitochondria can lead cells to rely more on glycolysis—a less efficient method of producing energy—even in the presence of oxygen. This phenomenon, known as the "Warburg effect," is commonly observed in cancer cells.• Metabolic Reprogramming: Mitochondrial alterations can cause metabolic shifts that support rapid cell proliferation, a hallmark of cancer. These changes enable cancer cells to adapt to environmental stresses and sustain their growth.• Genomic Instability: Defective mitochondria can lead to increased production of reactive oxygen species (ROS), which can damage DNA and contribute to the mutations observed in cancer cells.• Cause vs. Effect: While genetic mutations are prevalent in cancer cells, mitochondrial dysfunction may precede and even cause these mutations, rather than being a consequence of them.• Therapeutic Implications: Understanding cancer as a mitochondrial metabolic disease opens new avenues for treatment. Therapies aimed at restoring mitochondrial function or targeting the altered metabolic pathways could prove effective.
