Mitochondria migrate toward the cell membrane in response to high glucose levels

Research shows that high glucose levels cause mitochondria to move towards the periphery of pancreatic beta cells. This movement is linked to insulin secretion and may play a role in regulating blood sugar levels. The study found that inhibiting microtubules disrupted this process, suggesting a key role for these structures in mitochon...
