Because our panel of cancer cell lines used for the development of the cell line typing was limited to 14 cell lines, we intended to increase the number of cell lines by directly performing quantitative RT-PCR of Brm mRNA (using totally 4 PCR primer pairs), EGR1 mRNA (using totally 4 PCR primer pairs) and miR-199a-3p by adding 12 new cell lines using the same experimental protocol as used for Fig. 1a (Fig. 7). Here, EGR1 is linked to cancer.
