Abstract

Tripeptidyl aldehyde proteasome inhibitors have been shown to effectively increase viral capsid ubiquitination and transduction of recombinant adeno-associated virus type 2 (rAAV-2) and rAAV-5 serotypes. In the present study we have characterized a second class of proteasome-modulating agents (anthracycline derivatives) for their ability to induce rAAV transduction. The anthracycline derivatives doxorubicin and aclarubicin were chosen for analysis because they have been shown to interact with the proteasome through a mechanism distinct from that of tripeptidyl aldehydes. Our studies demonstrated that doxorubicin and aclarubicin also significantly augmented rAAV transduction in airway cell lines, polarized human airway epithelia, and mouse lungs. Both tripeptidyl aldehyde and anthracycline proteasome-modulating agents similarly augmented nuclear accumulation of rAAV in A549 and IB3 airway cell lines. However, these two cell types demonstrated cell specificity in the ability of N -acetyl- l -leucyl- l -leucyl- l -norleucine (LLnL) or doxorubicin to augment rAAV transduction. Interestingly, the combined administration of LLnL and doxorubicin resulted in substantially increased transduction (>2,000-fold) following apical infection of human polarized epithelia with either rAAV-2 or rAAV-5. In summary, the cell type specificity of LLnL and doxorubicin to induce rAAV transduction, together with the ability of these compounds to synergistically enhance rAAV transduction in polarized airway epithelial induction, suggests that these two classes of compounds likely modulate different proteasome functions that affect rAAV transduction. Findings from this study provide new insights into how modulation of proteasome function can be effectively used to augment rAAV transduction in airway epithelia for gene therapy of cystic fibrosis.

  • Use of proteasome inhibitors such as MG-132 and LLnL increases transduction, providing evidence that after endosome escape, AAV must elude proteasomes in the cytoplasm while traversing to the nucleus.

    “Use of proteasome inhibitors such as MG-132 and LLnL have been shown to increase transduction, providing evidence that after endosome escape, AAV must elude proteasomes in the cytoplasm while traversing to the nucleus (Fig. 8IV and V) (11, 51).”

    From Packaging Capacity of Adeno-Associated Virus Serotypes: Impact of Larger Genomes on Infectivity and Postentry Steps (2005) · cites this paper as [51]

    The introductory passage identifies Z-LLL as MG132 and reports that it and LLnL enhance rAAV transduction; the Results also show that LLnL increases transduction and nuclear accumulation of viral DNA. But the Discussion says how these agents alter rAAV interactions with the proteasome remains unclear. The paper does not establish that, after escaping endosomes, AAV must elude cytoplasmic proteasomes on its way to the nucleus. (LLM, conf=0.88)

  • Drugs/chemicals such as bafilomycin A, brefeldin A, and MG-132 augment rAAV transduction by acting on the level of endosome acidification, early-to-late endosome transition, and proteasome activity, respectively.

    “Studies have been carried out by a number of groups (11, 22, 50, 51) illustrating that drugs/chemicals such as bafilomycin A, brefeldin A, and MG-132 augment rAAV transduction by acting on the level of endosome acidification, early-to-late endosome transition, and proteasome activity, respectively.”

    From Packaging Capacity of Adeno-Associated Virus Serotypes: Impact of Larger Genomes on Infectivity and Postentry Steps (2005) · cites this paper as [51]

    The paper identifies MG132 (Z-LLL) as a proteasome inhibitor that can enhance rAAV transduction (introductory passage; Results). It does not address the claimed effects of bafilomycin A on endosome acidification or brefeldin A on early-to-late endosome transition. No page numbers are available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Proteasomes are a barrier for intracellular trafficking.

    “Proteasome inhibitors have been described in numerous studies to increase the transduction of rAAV postentry of the cell, suggesting that proteasomes are a barrier for intracellular trafficking (11, 51).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
