MCF-7 cell line was transfected with 5μg of vectors expressing JMJD6 WT (pcDNA3-JMJD6WT-V5), JMJD6 mut (pCDNA3-JMJD6MUT-V5) or with empty pCDNA3 (2 X 106 cells in a 100mm dish) using Exgen 500 (Euromedex) according to the manufacturer’s guidelines. Selection was initiated 48h after transfection in medium containing 750μg/ml of G418. After selection, cells were maintained in medium containing 300μg/ml of G418. Three commercially available lentiviral short hairpin RNA (shRNA) constructs targeting human JMJD6 and one negative control construct created in the same vector backbone (pLKO.1-Puro) were purchased from SIGMA. Puromycin selection (1μg/mL) was started 48h after lentiviral infection. The established cell lines have been already described and characterized [23 (link)].
