Liver-specific Nrf1 (NF-E2-p45-related factor 1) knockout mice develop nonalcoholic steatohepatitis. To identify postnatal mechanisms responsible for this phenotype, we generated an inducible liver-specific Nrf1 knockout mouse line using animals harboring an Nrf1(flox) allele and a rat CYP1A1-Cre transgene (Nrf1(flox/flox)::CYP1A1-Cre mice)....

Forkhead box O (FOXO; DAF-16 in worms) transcription factors, which are of vital importance in cell-cycle control, stress resistance, tumor suppression, and organismal lifespan, are largely regulated through nucleo-cytoplasmic shuttling. Insulin signaling keeps FOXO/DAF-16 cytoplasmic, and hence transcriptionally inactive. Conversely...
