Ex vivo incorporation of Chol siOAT3 into extracted endogenous lipoproteinsWe investigated the character of endogenous lipoproteins cheap ugg zone used as vectors for Chol siOAT3 and optimized the composition of ex vivo mixture of endogenous lipoproteins and Chol siOAT3 for animal experiments. We first obtained endogenous lipoproteins from mouse sera by ultracentrifugation. An analysis of lipid profiles using high performance liquid chromatography20 showed that the HDL fraction contained only HDL cholesterol, with no cholesterol derived from any other lipoproteins (Figure 2a), and that the LDL fraction contained only LDL cholesterol (Figure 2b). Moreover, western blotting revealed a characteristic apolipoprotein cheap ugg fringe boots profile for each lipoprotein fraction: the HDL fraction contained apolipoprotein A I (ApoA I) and no ApoB, whereas the LDL fraction contained ApoB (ApoB 100 and ApoB 48) but no apolipoprotein A I (Figure 2c). These results indicate that endogenous HDL and LDL had been successfully isolated. (a) HPLC analysis showing cholesterol levels of the serum and HDL fraction obtained from wild type mice. (b) HPLC analysis showing cholesterol levels of the serum and LDL fraction obtained from LDL receptor deficient (LDLR mice. (c) Western blotting of ApoA I and ApoB in the HDL and LDL fractions. (d) Gel shift assay of siOAT3 and Chol siOAT3. Electrophoretic mobility was examined using a 12% polyacrylamide gel after 100 pmol of each short interfering RNA (siRNA) were incubated with different volumes of the HDL fraction. ApoA I, apolipoprotein A I; ApoB, apolipoprotein B; Chol siOAT3, cholesterol conjugated siRNA targeting organic anion transporter 3 mRNA; HDL, high density lipoprotein; HPLC, high performance liquid chromatography; LDL, low density lipoprotein; OAT3, organic anion transporter 3; siOAT3, very cheap ugg boots from china unconjugated siRNA targeting OAT3 mRNA. Full figure and legend (67K) Next, we incubated siOAT3 or Chol siOAT3 with the HDL or LDL fraction ex vivo and evaluated the electrophoretic mobility of the resulting mixtures using polyacrylamide gels. Single bands were seen for siOAT3, both with and without the HDL fraction, at the position of 21 nucleotides (Figure 2d). In contrast, mixtures of 100 pmol of Chol siOAT3 and 1 and more of the HDL fraction did not show any bands corresponding to 21 nucleotides (Figure 2d). These mixtures were considered to be stable cheap womens ugg boots sale for at least 24 hours in vivo because the intensity and mobility of the mixtures did not change after the incubation with mouse sera at 37 for 24 hours (data not shown). Similar patterns of bands were seen when siOAT3 or Chol siOAT3 was mixed with the LDL fraction (data not shown). Taken together, these results indicate that Chol siOAT3 is incorporated into HDL and LDL in a saturable manner, whereas siOAT3 is not incorporated into these lipoproteins at all. We decided to mix 1 of the HDL or LDL fraction per 100 pmol of Chol siOAT3 for animal experiments because Chol siOAT3 could be fully incorporated into HDL or LDL at this ratio.
