Adding a tiny amount of methylene blue to heart cell power plants makes them use oxygen more efficiently, no matter what fuel they're burning.
Methylene blue makes heart cell power plants produce more harmful molecules when using one fuel (glutamate/malate), but less when using another (succinate), showing its effect depends on what the cell is burning.
Adding methylene blue doesn’t change how well heart cell power plants can hold onto calcium, meaning it doesn’t protect against the pore that can cause cell death under stress.
A tiny amount of methylene blue helps heart cells make energy better, but too much actually hurts them — it’s a classic case of 'less is more'.
Heart cells from diabetic rats have weaker power plants that leak more harmful molecules than those from healthy rats, which matches what scientists expect in diabetes-related heart damage.
