Metabolic Control over mTOR-Dependent Diapause-like State (Developmental Cell)

Hussein et al. report that, during starvation, mTOR is repressed through LKB1-AMPK, inducing a reversible metabolically active but epigenetically silenced embryonic diapause-like state that upregulates expression of the glutamine transporters SLC38A1/2. These transporters are required for the H4K16ac-negative, diapause state.
