In order to characterize the effect of lncRNAs in CML, we firstly performed lncRNA expression profiling microarray in newly diagnosed CML patients and healthy individuals¡¯ samples. We found that nuclear enriched abundant transcript1 (NEAT1), an lncRNA essential for the formation of nuclear body paraspeckles, is significantly repressed in in CML patients samplescompared with those of healthy donors (figure 1A). We found that NEAT1 expression was repressed by BCR-ABL, and the expression of NEAT1 could be restored after treatment with imatinib and BCR-ABL mediated pathway inhibitor or knockdown BCR-ABL in K562 cells (figure 1B). Moreover, knockdown of NEAT1 combining with imatinib treatment, could promote apoptosis of K562 cells (figure 1C). Importantly, the NEAT1-binding paraspeckle protein splicing factor proline/glutamine-rich (SFPQ) is required for NEAT1-mediated apoptosis of K562 cells. Furthermore, NEAT1 was shown to be regulated by c-Myc in K562 cells (figure 1D).
