How Cells Clear TOP1cc Through Autophagy — And Why This Changes the Game for Anti-Cancer Discovery
A major Cell paper has uncovered a completely new layer of DNA repair biology: cells use selective autophagy and lysosomes to process and remove Topoisomerase I cleavage complexes (TOP1cc)—the toxic DNA–protein crosslinks created during normal replication and when cells are exposed to TOP1-targeting drugs like camptothecin. According to the Cell article (2024), researchers discovered that: […]
