Unlocking the Unpaired: Strategic Advances in R-Loop and ...
2025-10-18
Translational genomics and molecular biology are being revolutionized by membrane-permeable nucleic acid probes. This thought-leadership article explores the mechanistic and strategic value of N3-kethoxal—a next-generation, azide-functionalized probe—for probing unpaired guanine bases, mapping R-loops, and illuminating the structural and interactional landscape of nucleic acids. Drawing on cutting-edge research, including recent findings on N2-alkyl-dG lesions and genome instability, we provide actionable guidance for researchers seeking to advance from descriptive structure probing to integrative, clinically relevant discovery.
