GATA3 downstream targets IL-5, IL-13, and STAT4 are influenced by GATA3 down-regulation. Semiquantitative RT-PCR on sorted GFP⁺ cells as in Figure 1C on KM-H2 (A), L-428 (B), U-HO1 (C), and L-1236 (D) cells. Messenger RNA of IL-5, IL-13, and STAT4 were amplified. A representative experiment of at least 3 independent repeated experiments is shown for each cell line.
