Abstract

Glioblastoma tumour cells release microvesicles (exosomes) containing mRNA, miRNA and angiogenic proteins. These microvesicles are taken up by normal host cells, such as brain microvascular endothelial cells. By incorporating an mRNA for a reporter protein into these microvesicles, we demonstrate that messages delivered by microvesicles are translated by recipient cells. These microvesicles are also enriched in angiogenic proteins and stimulate tubule formation by endothelial cells. Tumour-derived microvesicles therefore serve as a means of delivering genetic information and proteins to recipient cells in the tumour environment. Glioblastoma microvesicles also stimulated proliferation of a human glioma cell line, indicating a self-promoting aspect. Messenger RNA mutant/variants and miRNAs characteristic of gliomas could be detected in serum microvesicles of glioblastoma patients. The tumour-specific EGFRvIII was detected in serum microvesicles from 7 out of 25 glioblastoma patients. Thus, tumour-derived microvesicles may provide diagnostic information and aid in therapeutic decisions for cancer patients through a blood test.

  • mRNA profiling of serum-derived EV contents can discriminate between healthy and glioblastoma-bearing patients, and IDH-1, EGFRvIII, and c-myc alterations have been detected in EVs from glioblastoma or medulloblastoma samples.

    “For example, mRNA profiling of serum derived EV contents can discriminate between healthy and glioblastoma bearing patients [118]. IDH-1 (isocitrate dehydrogenase 1) transcripts have been detected from EVs isolated from the blood of glioblastoma bearing patients using immunoisolations of EVs targeting CD63 [119].”

    From Biogenesis of extracellular vesicles (EV): exosomes, microvesicles, retrovirus-like vesicles, and apoptotic bodies (2013) · cites this paper as [1]

    In the paper’s biomarker results (page not available), EGFRvIII mRNA was detected in serum microvesicles from 7 of 25 glioblastoma patients and in none of 30 normal control sera. That supports a distinction for this specific marker, but not the broader claim that mRNA profiling of serum-derived EVs can discriminate glioblastoma-bearing patients from healthy people generally. The IDH-1 sentence is attached to a different citation and is not assessed here. (LLM, conf=0.86)

  • The contents of released extracellular vesicles mirror aspects of the secreting cell.

    “the contents of the vesicles released mirror aspects of the secreting cell. [1]”
  • Extracellular vesicles can transfer RNAs such as non-coding RNAs from one cell to another and thereby contribute to inter-cellular communication.

    “Recent studies have confirmed that EV can transfer RNAs such as ncRNAs from one cell to another and thereby contribute to important roles in inter-cellular communication (3–9).”

    From Analysis of Extracellular RNA by Digital PCR (2014) · cites this paper as [5]

  • In GBM, communication between tumor cells and the microenvironment has a big impact on tumor progression.

    “In GBM, similar to other cancer types, the communication between tumor cells and its microenvironment has a big impact on tumor progression; and hence it provided a new approach for cancer treatment (3, 4).”
  • ELV preparations from various cell types contain distinctive repertoires of RNA populations including transcripts and non-coding RNAs.

    “ELV preparations from various cell types have demonstrated that they contain distinctive repertoires of RNA populations including transcripts (Valadi et al., 2007; Skog et al., 2008) and non-coding RNAs”

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.
