Figures
There is an error in the first sentence of the final paragraph of the “Impact of ABCB1 1199G>A polymorphism on the intracellular accumulation of Tac and CsA” subsection. The sentence should read:
“As depicted in Fig 7, Tac intracellular concentrations were strongly decreased, at all timepoints in cells overexpressing the 1199G wild-type allele when compared to control cells (transfected with empty vector) (Fig 7A, p<0.05) or to cells overexpressing the 1199A variant allele (Fig 7A, p<0.01; Fig 7B, p<0.01 statistics not presented in the figure for clarity).”
In Table 1, the final entry under the “References” column should read “29-30 & herein”. Please see the corrected Table 1 here.
Additionally, there are a few errors with some of the figure legends. Please view Figure 1, Figure 6, and Figure 7 with their corrected legends here.
Histograms generated from a flow cytometry analysis of (A) HEK293 transfected with the empty pcDNA3.1 vector (CTL HEK293 pcDNA3.1) and HEK293 cells transfected with ABCB11199G or 1199A and (B) K562 cells transfected with the empty pcDNA3.1 vector (CTL K562 pcDNA3.1), with ABCB11199G or 1199A. Cells were incubated with an FITC-conjugated anti-ABCB1 antibody (green line), a matched isotypic control (blue line) or not labeled (red line).
Intracellular accumulation of tacrolimus after 120 min of incubation (N = 3) (A) at six different concentrations (0.0015–0.5 μM) in CTL HEK293, CTL HEKpcDNA3.1, HEK1199G and HEK1199A and (B) at 0.05 μM in CTL K562, CTL K562 pcDNA3.1, K5621199G and K5621199A. Intracellular accumulation of CsA after 120 min of incubation (N = 3) (C) at six different concentrations (0.015–5 μM) in CTL HEK, CTL HEKpcDNA3.1, HEK1199G and HEK1199A and (D) at 0.5 μM in CTL K562, CTL K562pcDNA3.1, K5621199G and K5621199A. The intracellular accumulation of Tac or CsA in each cell line was normalized by reporting the absolute amounts of Tac or CsA (in ng) on the total amount of proteins in cell extracts, expressed in mg. * compared to CTL pcDNA3.1 *p<0.05 **p<0.01 ***p<0.001, # compared to 1199G/WT #p<0.05 ##p<0.01 ###p<0.001.
Intracellular accumulation of tacrolimus (0.05 μM) after 15, 30 sec, 1, 5, 10, 30 or 60 min of efflux (N = 6) in (A) CTL HEK293, CTL HEKpcDNA3.1, HEK1199G and HEK1199A and (B) CTL K562, CTL K562pcDNA3.1, K5621199G and K5621199A. Cells were pre-loaded with tac for 120 min before efflux. The intracellular accumulation of Tac in each cell line was normalized by reporting the absolute amounts of Tac (in ng) on the total amount of proteins in cell extracts, expressed in mg. * compared to CTL pcDNA3.1 *p<0.05 **p<0.01 ***p<0.001.
