Apoptosis--the Calcium Connection

Abstract
Calcium ions are crucial to many cellular processes including apoptosis. In their Perspective, [Demaurex and Distelhorst][1] explain new work that shows how calcium ions flowing between the endoplasmic reticulum (ER) and mitochondria regulate programmed cell death, highlighting the ER as a new gateway to apoptosis ([ Scorrano et al .][2]).
