What this study shows

AIMTOR is a genetically encoded BRET biosensor that reads out mTOR activity live in single cells and in specific subcellular compartments (cytosol, lysosome surface, nucleus, near mitochondria).

Abstract

ShowHide

mTOR signaling is an essential nutrient and energetic sensing pathway. Here we describe AIMTOR, a sensitive genetically encoded BRET (Bioluminescent Resonance Energy Transfer) biosensor to study mTOR activity in living cells. As a proof of principle, we show in both cell lines and primary cell cultures that AIMTOR BRET intensities are modified by mTOR activity changes induced by specific inhibitors and activators of mTORC1 including amino acids and insulin. We further engineered several versions of AIMTOR enabling subcellular-specific assessment of mTOR activities.

At a glance

Evidence type M Molecular — cells, biochemistry, structure Marked M because it is molecular or in-vitro work (model: HEK293 cells; primary hippocampal neurons and muscle cells (mouse); biosensor tool) rather than a whole-organism health-outcome study. That is often exactly where causal biology gets established -- the code says which system the finding was shown in, and nothing about how good the work is.
