Scrambled and pcDNA-3.1-14-3-3η-Flag were synthesized by Generay Biotech (Shanghai, China); while 14–3-3η- and NF-κB/p65 siRNA were purchased from Santa Cruz Biotechnology (http://datasheets.scbt.com/sc-43581.pdf, and https://datasheets.scbt.com/sc-29410.pdf) [12 (link), 16 (link)]. Cells were transiently transfected via lipofectamine 2000 reagent (Invitrogen, Carlsbad, USA), according to the manufacturer’s protocol (Note: plasmids used: 5 ng/ml. siRNAs used: 20 nM). After transfection, the cells were cultured in fresh medium supplemented with 10% FBS for another 24 h before being used for other experiments.
