• CF10 and EdU Drive Telomere Attrition in CRC

  2026-08-08

  Das and colleagues show that the fluoropyrimidine polymer CF10, but not 5-fluorouracil, strongly enhances 5-ethynyl-2′-deoxyuridine incorporation, DNA double-strand breaks, telomere loss, and mitotic catastrophe in colorectal cancer cells. The study links thymidylate stress to a telomere-dependent mechanism that may guide combination-treatment design, while remaining preclinical and cell-model dependent.
