Methods for the Study of Entotic Cell Death

Methods Mol Biol. 2019:1880:447-454. doi: 10.1007/978-1-4939-8873-0_28.

Abstract

Entosis is a mechanism of cell competition occurring in cancers that involves the engulfment and killing of neighboring cells. The death of ingested cells, called entotic cell death, usually occurs in a non-apoptotic, autophagy protein-dependent manner, where microtubule-associated protein light chain 3 (LC3) is lipidated onto entotic vacuoles. Here we present methods to quantify entotic cell death and its associated LC3 lipidation.

Keywords: Anoikis; Cannibalism; Cell-in-cell; Engulfment; Entosis; Soft agar; Time-lapse.
