Consistent with sequencing and PCR results, northern blots reveal abundant short transcripts derived from both CRIM1:1 and ZEB2:2g regions, processed in MCF10A, a normal human mammary epithelial cell line, but are downregulated in both MCF7 and MDA-MB-231, two aggressive breast cancer cell lines (Fig. 6D-F). This evidence concerns the gene CRIM1 and breast carcinoma.
