No. Sentence Comment
92 Two ABCC1-HA point mutants, L300A and I301A, displayed a mixed distribution pattern, indicating diminished basolateral targeting specificity.

93 In addition to their usual localization to the basolateral membrane, significant proportions of the L300A and I301A mutants were found in the apical vacuoles of every polarized HepG2 cell.

94 All other ABCC1 point mutants tested exhibited normal basolateral localization, which excludes the possibility that perturbed localization of the L300A and I301A mutants was caused by gross protein misfolding arising from a point mutation and inhibition of ABCC1 trafficking to the basolateral membrane.

102 The MCCs of the L300A mutant against APN and Na,K-ATPase were 0.59 &#b1; 0.06 and 0.62 &#b1; 0.08, respectively, indicating a mixed apical and basolateral localization pattern (Fig. 3B).

114 Only two variants, L300A and I301A, exhibited a mixed localization pattern.

120 The L300A and I301A mutants lost their basolateral-specific targeting and produced a mixed staining pattern at both the apical and basolateral sides (Fig. 4).

129 HepG2 cells were transiently cotransfected with 0.5 lg of the wild-type (A), L300A (B), or I301A (C) ABCC1-HA expression plasmids, along with 0.5 lg of empty vector pCMV-HA.

151 Single merged panels of representative apical, lateral, and x-z sections are shown. The L300A and I301A mutants displayed a mixed localization to the apical and basolateral membranes.

113 Representative merged immunofluorescence images of the transfected cells are shown. The positions of apical vacuoles formed between juxtaposed polarized cells are indicated by white arrowheads. Scale bar, 20 lm. Only two variants, L300A and I301A, exhibited a mixed localization pattern.
