CPT1B and infection: Interestingly, forced H19 expression also up‐regulated several genes involved in lipid breakdown, such as Acat2, Cpt1b, Ndafs4, Pck2, Cyp1a2 and Hadha at 72 hours after Ad‐H19 infection, although Pck2 and Cyp1a2 were down‐regulated while Cpt1b, Acads and Hadha were up‐regulated at 36 hours after infection (Figure 2B panels c and d).
