Abstract

The existence of subpopulations of cells in cancers with increased tumor-initiating capacities and self-renewal potential, often termed "cancer stem cells," is a much discussed and key area of cancer biology. Such cellular heterogeneity is very important because of its impact on therapy and especially states of treatment resistance. A major question is whether there is plasticity for evolution of these cell states during tumorigenesis that can involve movement between cell populations in a reversible fashion. In this review, we discuss the possible role of epigenetic abnormalities as well as genetic alterations in such dynamics and in the creation of cellular heterogeneity in cancers of all types.

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

  • The blood circulation system is a key component in metastasis because many malignant cells migrate as circulating cancer cells through blood vessels.

    “The blood circulation system is also a key component in metastasis because many malignant cells migrate as circulating cancer cells through blood vessels [105].”

    From Microfluidic modelling of the tumor microenvironment for anti-cancer drug development (2019) · cites this paper as [105]

    The sections on tumor heterogeneity discuss differences between primary tumors and metastases, and the section on epigenetic alterations mentions migratory capabilities. Neither addresses whether malignant cells travel through blood vessels as circulating cancer cells or establishes the blood circulation system’s role in metastasis. Searches for circulating tumor cells, blood vessels, bloodstream, and vascular dissemination found no supporting passage. (LLM, conf=0.76)

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.
