Notably, mir-612, which is expressed from the same region of the 3′ end of the long isoform of NEAT1 and in the same direction, is one of the most abundant spliceosomal miRNAs in the MCF-10A normal breast cell line (Table 1), but is not found among the spliceosomal miRNAs of the breast cancer cells [5] (Table 1). Here, NEAT1 is linked to breast cancer.
