Cellular fibronectin-targeted fluorescent aptamer probes for early detection and staging of liver fibrosis
Liver fibrosis is a key process in the progression of chronic liver disease to cirrhosis. Currently, early diagnosis and precise staging of liver fibrosis remain great challenges. Extracellular matrix (ECM) molecules expressed specifically during liver fibrosis are ideal targets for bioimaging and detection of liver fibrosis. Here, we report that fluorescent probes based on a nucleic acid aptamer (ZY-1) targeting cellular fibronectin (cFN), a critical ECM molecule significantly accumulating during liver fibrosis, are promising bioimaging agents for the staging of liver fibrosis. In the work, the outstanding binding affinity of ZY-1 to cFN was validated through an in vitro model of human-derived hepatic stellate cells (HSCs). Subsequently, we constructed different ZY-1-based fluorescent probes and explored the real-time imaging performance of these fluorescent probes in CCl4-induced mouse models of different liver fibrosis stages. The ZY-1-based fluorescent probes, for the first time, effectively identified and distinguished early-stage liver fibrosis (stage 3 of Ishak 6) from advanced liver fibrosis (stage 5 of Ishak 6). The proof-of-concept study provides compelling evidences that ZY-1-based probes are a promising tool for the early diagnosis and staging of liver fibrosis and paves the way for further development of clinical-related diagnosis strategies for fibrotic diseases of the liver and other organs.
Statement of significance
Currently, early diagnosis and accurate staging of liver fibrosis continue to present significant challenges. This study demonstrates that fluorescent probes based on the nucleic acid aptamer ZY-1, which targets cellular fibronectin (cFN)—a crucial extracellular matrix (ECM) molecule that significantly accumulates during liver fibrosis—are promising bioimaging agents for staging liver fibrosis. The ZY-1-based fluorescent probes effectively identified and differentiated early-stage liver fibrosis from advanced liver fibrosis. This proof-of-concept study not only provides compelling evidence that ZY-1-based probes show promise for the early diagnosis and staging of liver fibrosis but also paves the way for further investigations into the use of ZY-1 in detecting other diseases associated with cFN.
