PTEN and B-cell non-Hodgkin lymphoma: We focused on miR-494 for two reasons: (i) miRDB analysis identified two conserved complementary 8-mer sequences in the 3′-UTR of PTEN mRNA that miR-494 is likely to base-pair with, (ii) its location at 14q32, the aberrantly regulated chromosome 14 region that has been previously described in B-cell lymphomas [23].
