Advances in Tumor Marker Detection Based on CRISPR-Cas System-assisted Molecular Self-Assembly Strategies
摘要
Abstract
The ultra-low abundance of tumor markers and interference from complex matrices in liquid biopsy represent the primary bottlenecks for early cancer screening,and single amplification strategyis can bardly achieve a good balance among sensitivity,specificity,and reaction speed.In recent years,clustered regularly interspaced short palindromic repeats(CRISPR)and CRISPR-associated proteins(Cas)system-assisted molecular self-assembly strategy was used in detection of tumor biomarker.Leveraging the precise recognition and efficient cleavage activity of CRISPR-Cas system,this synergistic strategy effectively overcomes the challenges of background leakage and sluggish kinetics associated with traditional enzyme-free self-assembly.By constructing a cascade signal amplification loop,CRISPR-Cas system-assisted molecular self-assembly strategies enable the ultrasensitive and highly specific detection of trace markers such as circular tumor DNA(ctDNA)and micro RNA(miRNA).Herein,recent research progress on CRISPR-Cas system-assisted molecular self-assembly strategies for tumor marker detection was reviewed.The applications of this dual signal amplification mechanism in the field of physical sensing were introduced.The deep integration of the CRISPR-Cas system-assisted molecular self-assembly strategies with artificial intelligence,solid-state reagent storage,and microfluidic technology constituted a pivotal direction for advancing its application in clinical point-of-care testing.关键词
