Differential Expression Patterns of EGF, EGFR, and ERBB4 in Nasal Polyp Epithelium
Fig 5
Quantitative determination of mRNA by means of real-time RT-PCR for EGF, EGFR, and ERBB4 in control, GC-naive and GC-treated patients with NPs.
Solid lines show the median level of different groups. Statistical analysis for mRNA level comparison was performed with the Wilcoxon matched-pairs signed-rank test. Correlation between JUN and EGF or ERBB4 was evaluated by Spearman Rank analysis with correlation coefficient (r). *, p <0.05; **, p <0.01; ***, p <0.001; ns, no significance.
