Similar to H19 overexpression though, silencing H19 expression also up‐regulated most of the genes involved in lipid breakdown, such as Acat2, Cpt1b, Ndafs4, Pck2, Cyp1a2, Acads and Atpsa1, at 72 hours after Ad‐H19 infection, although most of them were down‐regulated at 36 hours after infection (Figure 3B panels c and d). The gene discussed is CYP1A2; the disease is infection.
