miRNA control of chaperone networks. Ischemia leads to mitochondrial Ca2+ overload through MAM and then dysfunction of mitochondria releases ROS, a key element linking the organelle network to the inflammatory network of chaperone. One miRNA (miR-200 or miR-181) or its antagomir/inhibitor can target HSP70/GRP75/GRP78 and BCL2 at the same time and thus efficiently regulate cerebral ischemic cell death pathways.
