Phase Separation of ZBED2 Stabilizes ILK to Drive Metastasis and Immune Evasion in Esophageal Squamous Cell Carcinoma.

ZBED2 forms phase-separated nuclear condensates in esophageal squamous cell carcinoma, correlating with inferior survival and metastasis while stabilizing ILK to support immune evasion.

• Why it matters: Metastasis and immune escape drive mortality in ESCC, but the molecular pathway linking nuclear condensates to ILK-dependent immunosuppression was unclear.
• What they did: The study assessed patient correlations, then used mechanistic experiments showing ZBED2 phase separation, increased HSP90AA1 transcription, enhanced HSP90AA1–ILK interaction, and reduced ILK ubiquitination.
• The result: Stabilized ILK increased PD-L1 transcription and CD8+ T cell exhaustion, creating an immunosuppressive microenvironment that facilitates ESCC metastasis and supports ZBED2 as a therapeutic target.
