Lung adenocarcinoma cells A549 (CCL-185, ATCC, Manassas, VA, USA) and H460 (
HTB-177, ATCC, Manassas, VA, USA) were cultured in Dulbecco’s modified eagle medium (
DMEM; CAT#01–055, Biological industries, Beit HaEmek, Israel). Meanwhile, human embryonic lung fibroblasts HFL-1 (CC-Y1584, EK-Bioscience, Shanghai, China) were cultured in
Ham’s F-12 (CAT#01–095, Biological industries). All media were then supplemented with 10% fetal bovine serum (FBS; GIBCO™, CAT# 10270106, Life Technologies, San Jose, CA, USA), 100 units/mL
penicillin, 100 µg/mL
streptomycin, and 2 mM
L-glutamine, which were all purchased from Biological industries (Kibbutz Beit Haemek, Israel). Non-essential amino acids (
NEAA; CAT# X0557, 1: 100, Biowest, Logan, Utah, USA) were employed for HFL-1 culture. Afterwards, the cells were cultured in a
humidified incubator (Thermo Fisher Scientific Inc., Waltham, MA, USA) at 37 °C with 5% CO
2.
A549 cells were transfected with the HA-BIRC5 expression vector (pcDNA3-HA-BIRC5) and Myc-DR5 expression vector (DR5 Myc-tag) or corresponding empty vector (pcDNA) following the instructions of the
Lipofectamine 2000 transfection reagent (CAT# 11668019, Invitrogen, Carlsbad, CA, USA). Cells were transfected with 1 μg of pcDNA3-HA-BIRC5 and DR5 Myc-tag or the corresponding empty vector pcDNA. After a 24-h period of transfection, the cells were treated with NPs for subsequent analyses.
