Confirmation of microarray data. RT-PCR was done using total RNA from wild-type mouse lung (line 1), transgenic mouse lung (line 2) and PPAP9 cells (line 3). Scg2: secretogranin 2, Chga: chromogranin, Cav-1: caveolin1, Cav-2: caveolin 2, Ascl1: achete-scute complex homologue 1, Igf-2: insulin-like growth factor 2, FoxA2: forkhead box A2, A, 18S: 18 S ribosomal RNA M: marker.
