Partially Unspliced and Fully Spliced ELF3 mRNA, Including a New Alu Element in Human Breast Cancer

Using modified representational difference analysis, a DNA fragment (GC3) was isolated as a difference between a breast cancer and a normal cell line from the same patient. GC3 proved to be a fragment of intron 7 of the ELF3 gene, an ets family transcription factor, amplified in the breast cancer cell line. Using genomic walking technology, a new Alu (Alu(kwd)) was found downstream of GC3 in an antisense position between nt 8762 and nt 8763...
