Cell-in-cell structures, or entosis, are common in cancers. New research shows Kras oncogenes and epithelial cadherins regulate entosis, highlighting its complex role in malignancy.
Area of Science:
- Cell biology
- Cancer research
- Molecular oncology
Background:
- Cell-in-cell structures, termed entosis, are observed in human cancers.
- The prognostic significance of entosis in malignancies is not fully understood.
Purpose of the Study:
- To investigate the regulation of entosis in the context of human malignancies.
- To explore the role of specific oncogenes and tumor suppressors in entosis.
Main Methods:
- Analysis of entosis in human cancer samples.
- Investigating the impact of Kras oncogene expression on entosis.
- Examining the role of epithelial cadherins (E-cadherin and P-cadherin) in entosis regulation.
Main Results:
- Entosis is stimulated by the oncogene Kras.
- Epithelial cadherins (E-cadherin and P-cadherin), a class of tumor suppressors, also stimulate entosis.
- These findings reveal a complex regulatory network governing entosis.
Conclusions:
- Kras oncogenes and epithelial cadherins play a role in stimulating entosis.
- Entosis regulation is intricate and involves both oncogenic and tumor-suppressive pathways.
- Further research is needed to define the prognostic impact of entosis in human cancers.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
