A Nonapoptotic Cell Death Process, Entosis, that Occurs by Cell-in-Cell Invasion
Open accessAbstract
Epithelial cells require attachment to extracellular matrix (ECM) to suppress an apoptotic cell death program termed anoikis. Here we describe a nonapoptotic cell death program in matrix-detached cells that is initiated by a previously unrecognized and unusual process involving the invasion of one cell into another, leading to a transient state in which a live cell is contained within a neighboring host cell. Live internalized cells are either degraded by lysosomal enzymes or released. We term this cell internalization process entosis and present evidence for entosis as a mechanism underlying the commonly observed "cell-in-cell" cytological feature in human cancers. Further we propose that entosis is driven by compaction force associated with adherens junction formation in the absence of integrin engagement and may represent an intrinsic tumor suppression mechanism for cells that are detached from ECM.

“Entosis is a live-cell engulfment pathway occurring between two neighbouring cells, one of which will be actively engulfed by the other to form a ‘cell-in-cell’ structure [35].”
From LC3-Associated Phagocytosis (LAP): Connections with Host Autophagy (2012) · cites this paper as [35]
In the citing paper
“Entosis is mainly triggered by the detachment of epithelial cells from the extracellular matrix and consequent loss of integrin signaling [263, 694]”
From Molecular mechanisms of cell death: recommendations of the nomenclature committee on cell death 2018. (2018) · cites this paper as [694]
In the citing paper
“Once engulfed, entotic cells are often eliminated by a RCD subroutine that occurs independently of BCL2 proteins and caspases [694, 704], but relies (at least in part) on a specific autophagy-related process commonly known as LC3-associated phagocytosis (LAP) [509, 705, 706].”
From Molecular mechanisms of cell death: recommendations of the nomenclature committee on cell death 2018. (2018) · cites this paper as [694]
In the citing paper
“abrogation of entosis by a chemical ROCK inhibitor reportedly favors the anchorage-independent growth of malignant cells [694].”
From Molecular mechanisms of cell death: recommendations of the nomenclature committee on cell death 2018. (2018) · cites this paper as [694]
In the citing paper
“the uptake of entotic cells is an integrin-independent process promoted by the formation of junctions between engulfing and entotic cells that involve the adhesion proteins cadherin 1 (CDH1; also known as E-cadherin) and catenin alpha 1 (CTNNA1) [694, 699].”
From Molecular mechanisms of cell death: recommendations of the nomenclature committee on cell death 2018. (2018) · cites this paper as [694]
In the citing paper
“Entotic cell death has been documented in several human neoplasms, presumably operating as an oncosuppressor mechanism [694, 695, 701, 709, 710].”

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.
