molecularNote | A loxP site flanked neomycin resistance gene cassette replaced 162 nt of the adenylate-uridylate rich element (ARE) sequence. Cre-mediated recombination removed the neo cassette. Deletion of the ARE increases the half-life of the mRNA and results in constitutive expression of a low level of IFN-gamma under normal physiologic conditions. |
