The specific induction of the NFE2L1-006 isoform is highly conserved, as similar inductions were obtained in HeLa (upregulated by up to 2-fold), triple negative breast cancer MDA-MB-231 (2-fold) and SK-N-BE(2)C neuroblastoma cells (1.7-fold, Fig. 5a–c). This evidence concerns the gene NFE2L1 and triple-negative breast carcinoma.
