Regulation of Epidermal Growth Factor Receptor Signaling and Erlotinib Sensitivity in Head and Neck Cancer Cells by miR-7
Figure 6
Microarray analysis of miR-7-downregulated genes in HN5 and FaDu cells.
(A) Volcano plots representing array probes between HN5 (left) and FaDu (right) cells 24 h after transfection with miR-7 or miR-NC precursor molecules. Assigning a cut off of ±1.5-fold change (miR-7 vs miR-NC) and p<0.05, significantly downregulated probes are in green and significantly upregulated probes are in red. (B) Cluster analysis of miR-7-downregulated genes in HN5 and FaDu cells, where green and red shading corresponds to downregulated and upregulated genes, respectively. (C) Venn diagram of miR-7-downregulated genes in HN5 and FaDu cells. (D) Scatter plot of miR-7-downregulated genes common to HN5 and FaDu cells (R2 = 0.435, p<0.001).
