NR4A3 and cancer: Strikingly, upon analysis of the expression of all 20 putative miR-7 target genes in the pooled fractions of cancer and stromal cells isolated by LCMD (Fig. 2f), we observed that FOS, NR4A3, and PIK3CD presented the highest expression in stromal cells relative to cancer cells being 26, 19, and 12 fold more abundant, respectively.
