This was the quote I found most interesting...
"Dr. Elrod's team also found that, while it can improve cell survival after heart injury, increased MCUB activity comes at the expense of mitochondrial energy production. "MCUB induction is a compensatory change," explained Dr. Elrod. Just like an emergency responder, MCUB moves in and tries to reduce
cell death and aid cell survival—however, the reduction in mitochondrial calcium uptake is also maladaptive and limits the cell's ability to increase energy during stress."
