Stat6 decoy does not alter mRNA expression of IL-4 receptors.
Freshly isolated mRNA was obtained from control (lanes a, b, g), Stat6 decoy (lane c), scramble ODN-transfected D10 cells (lane d), or anti–IL-4 antibody treated (lane f) or anti–IL-3 antibody treated (lane e) cells in the absence (lanes a, e, f) or presence of IL-4 (lanes b through d). RNA was then hybridized with [33P]-labeled RNA probes corresponding to transcripts for individual murine γc-receptors (mCR-1) according to PharMingen protocol (see “Materials and methods”). The Rnase-protected fragments were separated on 5% PAGE, dried, and exposed to x-ray film.
