| Popis: | Summary Entosis is a cell death mechanism that is executed through neighbor cell ingestion and killing that occurs in cancer tissues and during development. Here, we identify JNK and p38 stress-activated kinase signaling as an inducer of entosis in cells exposed to ultraviolet (UV) radiation. Cells with high levels of stress signaling are ingested and killed by those with low levels, a result of heterogeneity arising within cell populations over time. In stressed cells, entosis occurs as part of mixed-cell death response with parallel induction of apoptosis and necrosis, and we find that inhibition of one form of cell death leads to increased rates of another. Together, these findings identify stress-activated kinase signaling as a new inducer of entosis and demonstrate cross talk between different forms of cell death that can occur in parallel in response to UV radiation. Graphical abstract Highlights • UV radiation induces entosis in cancer cells • JNK and p38 stress kinases regulate entosis induction • Entosis induction involves heterogeneous inactivation of JNK over time • Cells ingested by entosis maintain high levels of JNK signaling Cellular physiology; Molecular biology; Cell biology |
