Abstract

Although the expression of long noncoding RNA (lncRNA) is altered in hepatocellular cancer (HCC), their biological effects are poorly defined. We have identified lncRNA with highly conserved sequences, ultraconserved lncRNA (ucRNA) that are transcribed and altered in expression in HCC. Extracellular vesicles, such as exosomes and microvesicles, are released from tumor cells and can transfer biologically active proteins and RNA across cells. We sought to identify the role of vesicle-mediated transfer of ucRNA as a mechanism by which these novel lncRNA could influence intercellular signaling with potential for environmental modulation of tumor cell behavior. HCC-derived extracellular vesicles could be isolated from cells in culture and taken up by adjacent cells. The expression of several ucRNA was dramatically altered within extracellular vesicles compared to that in donor cells. The most highly significantly expressed ucRNA in HCC cell-derived extracellular vesicles was cloned and identified as a 1,198-bp ucRNA, termed TUC339. TUC339 was functionally implicated in modulating tumor cell growth and adhesion. Suppression of TUC339 by siRNA reduced HCC cell proliferation, clonogenic growth, and growth in soft agar. Thus, intercellular transfer of TUC339 represents a unique signaling mechanism by which tumor cells can promote HCC growth and spread. These findings expand the potential roles of ucRNA in HCC, support the existence of selective mechanisms for lncRNA export from cells,…

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

  • TUC339 is a long non-coding RNA that is selectively released in EV from hepatocellular cancer cells and is implicated in modulating tumor cell behavior.

    “We also analyzed expression of TUC339, a long non-coding RNA that is selectively released in EV from hepatocellular cancer cells and is foundationally implicated in modulating tumor cell behavior (15).”

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.
