A. Schematic diagram of growth factor signaling and transcriptional regulation. Red indicates genes with increased expression in LAPE cells compared with LAPN cells, and blue indicates genes with decreased expression. B. Immuno- blot analysis of the indicated proteins confirmed increased protein expression in LAPE cells predicted by GeneChip data. C. Relative RT-PCR for the transcription factor C/EBP delta confirmed GeneChip data of increased expression in LAPE cells com- pared with LAPN cells. D. TaqMan analysis confirmed increased expression of GADD153 in LAPE cells compared with LAPN cells. Data in A represent the means of fold-increase or – decrease in LAPE cells (p < 0.05, n = 5). Data in B, C, and D are rep- resentative of 2 to 3 separate cell preparations. Page 7 of 13 (page number not for citation purposes)
