Transcriptomic Signature of 3D Hierarchical Porous Chip Enriched Exosomes for Early Detection and Progression Monitoring of Hepatocellular Carcinoma

Advanced Science, Volume 11, Issue 14, April 10, 2024.
Hepatocellular carcinoma (HCC), a deadly tumor, lacks effective non‐invasive diagnosis via current serum markers. The innovative SiO2‐chip enriches exosomes efficiently, unveiling HCC‐specific lncRNAs like LUCAT‐1 and EGFR‐AS‐1. Validated by qRT‐PCR, integrating these lncRNAs with traditional markers significantly enhances diagnostic accuracy. Moreover,
