FZD4 and non-small cell lung carcinoma: We used a novel stem-loop array-reverse transcription-PCR (SLA-RT-PCR) assay to assess miRNA:target mRNA interaction at the specific FZD4-miR-SNP locus and detected miRNA-mediated FZD4 mRNA cleavage and 3′-uridylation in FZD4-SNP (C, rs713065) allele-bearing H1299 and H322 NSCLC cells, but not in FZD4-WT (T allele)-containing A549 and normal human bronchial epithelial cells.
