BATF condensation drives gastric cancer metastasis via chromatin association and transcriptional regulation.

BATF condensation promotes gastric cancer metastasis by enhancing chromatin binding and transcriptional regulation of TM4SF1.

• Why it matters: Understanding the role of liquid-liquid phase separation (LLPS) in gastric cancer (GC) could reveal new mechanisms of tumor progression and identify potential therapeutic targets, as its relationship with GC remains unclear.
• What they did: The study used ATAC-seq, RNA-seq, and ChIP-seq analyses on GC tissues and cell lines, showing increased BATF expression and DNA-binding activity, with BATF forming nuclear condensates that influence gene regulation.
• The result: BATF LLPS facilitates its binding to TM4SF1 regulatory regions, promoting focal adhesion formation and GC metastasis, thus highlighting LLPS as a key factor in GC progression and potential treatment strategies.
