A method for treating cancer in a subject in need thereof includes administering to cancer cells of the subject an agent effective to modulate the level of DNMT1-associated RNA and/or the interaction of DNMT1-associated RNA and DNMT1 in the cancer cells of the subject. Embodiments described herein relate to RNAs (e.g., IncRNAs) associated with DNA methyltransferase 1 (DNMTI-associcated RNA) in human cancer cells, methods and compositions of modulating the levels of DNMTI-associcated RNA and/or the interaction of DNMT1-associated RNA and DNMT1 in cancer cells of the subject to treat cancer cells or a subject in need thereof, and/or methods of measuring the expression profile of DNMT1 associcated RNA to determine whether the subject has cancer or an increased risk of cancer and/or the efficacy of a therapeutic regimen agent.Une méthode de traitement du cancer chez un sujet qui en a besoin comprend l'administration à des cellules cancéreuses du sujet d'un agent efficace pour moduler le niveau d'ARN associé à DNMT1 et/ou de l'interaction de l'ARN associé à DNMT1 dans les cellules cancéreuses du sujet.
