MALAT1 and chronic myelogenous leukemia, BCR-ABL1 positive: Herein, the working noncancer-derived secondary structural model of MALAT1 was compared to previously published RNA structural probing data in chronic myeloid leukemia (CML)-derived K562 cells [27] and in cervical cancer-derived HeLa cells [28,29] to identify putative differences between cancerous and noncancerous MALAT1 structural models [15].
