PRKAA1 and lentivirus infection: As a result, the expression of genes encoding AMPKα1 and AMPKα2 (Prkaa1 and Prkaa2, respectively) and total AMPKα in iWAT-SVF cells were significantly reduced and the activation of AMPK signaling by A-769662 was successfully blocked after Cre lentivirus infection (Figures 9E–G).
