Abstract

AIM: Development of EGF-liposomes (LP-EGF) for selective molecules delivery in tumors expressing EGFR. MATERIAL & METHODS: In vitro cellular interaction of EGF-LP and nontargeted liposomes (LP-N) was assayed at 37 and 4 °C in cells expressing different EGFR levels. Receptor-mediated uptake was investigated by competition with a monoclonal antibody anti-EGFR. Selective intracellular drug delivery and efficacy was tested by oxaliplatin encapsulation. In vivo biodistribution of LP-N and LP-EGF was done in xenograft model. RESULTS: LP-EGF was internalized by an active and selective mechanism through EGFR without receptor activation. Oxaliplatin LP-EGF decreased IC50 between 48 and 13% in cell EGFR+. LP-EGF was accumulated in tumor over 72 h postdosing, while LP-N in spleen. CONCLUSION: LP-EGF represents an attractive nanosystem for cancer therapy or diagnosis.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • EGF-liposome conjugates remarkably reduced IC50 of oxaliplatin in colorectal cancer cells overexpressing EGFR, but not in EGFR-negative colorectal cancer cells.

    “EGF-liposome conjugates remarkably reduced the IC50 value of oxaliplatin in colorectal cancer cells which overexpressed ERFR, though not in the EGFR-negative colorectal cancer cells [51].”
  • Enhanced EPR effect and therapeutic efficiency may be achieved by targeting EGFR in TME.

    “This study indicated that the enhanced EPR effect and therapeutic efficiency may be achieved by targeting EGFR in TME.”

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.
