Liquid-liquid phase separation in hepatocellular carcinoma.

Area of Science:

• Cell Biology
• Biochemistry
• Oncology

Background:

• Liquid-liquid phase separation (LLPS) forms membraneless intracellular compartments.
• These compartments create unique biochemical environments within cells.
• Aberrant LLPS is increasingly linked to cancer development and progression.

Purpose of the Study:

• To review the role of LLPS in hepatocellular carcinoma (HCC).
• To focus on the regulation and dysregulation of cellular condensates in HCC.
• To discuss potential therapeutic strategies targeting LLPS in HCC.

Main Methods:

• Literature review of recent studies on LLPS in HCC.
• Analysis of preclinical models of HCC exhibiting aberrant phase separation.
• Synthesis of current understanding of condensate formation and function in cancer cells.

Main Results:

• LLPS impacts oncogenic signaling, transcriptional regulation, and genome stability in cancer.
• Aberrant biomolecular condensate formation is observed in HCC preclinical models.
• Dysregulation of cytoplasmic and nuclear condensates is a key feature in HCC.

Conclusions:

• LLPS plays a significant role in HCC pathogenesis.
• Understanding LLPS in HCC provides insights into cancer biology.
• Targeting aberrant phase separation presents novel therapeutic opportunities for HCC.
