Human mir-155 is predicted based on homology to a cloned miR from mouse (MIR:MI0000177) [1], and later experimentally validated in human HL-60 leukemia cells [2]. Like the mouse miRNA, human mir-155 resides in the non-coding BIC transcript (EMBL:AF402776), located on chromosome 21 [3]. The mature form differs from that in mouse at a single position. Eis et al. confirm that miR-155 is processed from the BIC transcript in human, and demonstrate elevated expression of miR-155 in lymphoma samples [4].
