Where this comes from

Abstract

Cholesterol levels in mammalian cells are controlled by an intricate mechanism in which the transcription factor SREBP plays a key role. Work in this issue (Radhakrishnan et al., 2008) employing direct measurement of endoplasmic reticulum cholesterol levels offers insights into the "switch" that controls this system with surprising precision.
