Fig. 1From: Arsenic trioxide reduces chemo-resistance to 5-fluorouracil and cisplatin in HBx-HepG2 cells via complex mechanismsEstablishment of HepG2-HBx cell lines. qRT-PCR and western blot were used to evaluate the expression levels of HBx mRNA and protein in empty vector-transfected HepG2 cells, HBx-transfected HepG2 cells and HepG2.2.15 cells. All data were expressed as mean ± s.e.m., n = 4Back to article page
