What to know about Newly identified C/EBPγ protein links cancer cell plasticity and DNA repair

Researchers have identified the transcription factor C/EBPγ as a regulator that promotes both epithelial-mesenchymal transition (EMT) and DNA double-strand break repair in lung adenocarcinoma cells. The study suggests that C/EBPγ helps cancer cells become more aggressive and resistant to chemotherapy, potentially offering a new target for therapeutic intervention.

Why it matters

The findings, published in Cell Death Discovery, provide new insights into how cancer cells acquire aggressive features and resistance to anticancer treatments.

Common ground

EMT is a reversible cellular program in which epithelial cancer cells acquire mesenchymal characteristics, enhancing their mobility, invasiveness and adaptability.
