just a wildguessing... Ac anteroseptal MI is due to LAD ischemia and there is apoptosis involved in "cell death in ischemia and reperfusion". Preventing apoptosis may be a potential therapeuthic target limiting repefusion injury.

this question is from an actual exam, why would there be less Bcl2 in the normal tissue?? wouldnt there be more in the Normal tissue since it is anti-apoptotic since we dont want the cells to apoptose??
