Gene expression of mRNA of BIP and PAHX among Hek-293/BMN-FVIIIΔB-I-GFP cell population. A and B) Gene expression of mRNA of BIP and PAHX in Hek-293/BMN-FVIII∆B-I-GFP cells and Hek-293 non-transfected cells. Data are reported as expression relative units (ERU) and are represented as the means ± SEM. We used nonparametric t-test (Mann Whitney), one-tail and data were considered statistically significant (p < 0.05). The asterisks denote significant differences compared to non-transfected Hek-293 (** p < 0.01).
