An error occurred in the sequence of the antisense oligonucleotide shown in the supporting information file of this manuscript. New, corrected supporting information can now be found on its Wiley InterScience abstract page. Information was also missing from the caption of Figure 5; the corrected caption is as follows: Figure 5. a) Flow cytometry experiment showing the fluorescence intensity of PC-3 cells incubated with Cy3-labeled AON (400 nM) free, complexed to G5 PAMAM or entrapped in plain or Fab 0-PEG 115-b-P(PrMA 28-co-MAA 53)/G5 PAMAM PICMs (N/(P + COO-) molar ratio of 1.5). b) Confocal microscopy images of PC-3 cells after treatment with Cy3-AON (red, Panel ii) complexed to A) G5 PAMAM or B) Fab 0-PEG 115-b-P(PrMA 28-co-MAA 53)/G5 PAMAM PICMs. Endosomes/lysosomes were stained by LysoTracker (green, Panel i), and the images were merged in Panel iii. c) Bcl-2 gene silencing in PC-3 cells transfected for 5 h with AON (400 nM) or siRNA (25 nM) complexed to G5 PAMAM or entrapped in plain or Fab 0-PEG 115-b-P(PrMA 28-co-MAA 53)/G5 or G3 PAMAM PICMs at N/(P + COO-) of 1.5 (final volume of the transfection medium is 1 mL). Control cells were treated with medium alone. The effect of preincubation with 10% FBS, free CD71 or bafilomycin is indicated on the graph. The inset is representative of immunoreactive Bcl-2 and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) as determined by immunoblotting. The molar ratio of the Fab 0-PEG 145-b-P(PrMA 27-co-MAA 58) versus PEG 115-b-P(PrMA 28-co-MAA 53) is 2% for all the experiments. The results are representative of several independent experiments. The first 3 lanes on the left hand side of the inset represent the control-untreated cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
