0This study identifies the protein CBX2 as a critical driver of omental metastasis in ovarian carcinoma by enhancing the production of pro-metastatic extracellular vesicles. The researchers demonstrate that CBX2 utilizes liquid-liquid phase separation to transcriptionally upregulate FLOT1, which subsequently triggers the remodeling of lipid rafts on cell membranes. These remodeled microdomains facilitate the sorting of oncogenic cargo and the secretion of vesicles that promote tumor invasion and spread. Clinical data further validate these findings, showing that elevated CBX2 levels correlate with advanced cancer stages and poor patient outcomes. Ultimately, the research highlights the CBX2-FLOT1 axis as a potential therapeutic target for disrupting the communication networks that fuel ovarian cancer progression.
