Among the top 100 genes found to be alternatively spliced in the human BT549 breast cancer cells, 65 of the same genes were also identified as alternative spliced in the mouse mammary EO771 cell line upon miR-200c restoration (Figure 4D, Supplementary Tables S4 and S5), despite finding only one conserved splicing factor (QK) (Figure 5C). This evidence concerns the gene QKI and breast cancer.
