MicroRNA-223 (miR-223) was identified bioinformatically and subsequently characterized in the hematopoietic system, where it truly is mostly expressed within the myeloid, granulocytic, and monocytic compartments [3,4], but not in B and T lymphocytes. The highest levels of expression is observed in bone marrow CD34- fraction, that is representative of lineagecommitted precursors and mature hematopoietic cells [5]. The miR-223 locus is located around the X chromosome and is transcribed independently of any recognized genes [5,6]. MiR-223 acts as “a finetuner” of granulocytic differentiation and maturation [7] and promotes granulocytic differentiation in acute promyelocytic leukemia (APL) cells treated with 1 Adrenergic Inhibitors Related Products retinoic acid (RA) which can induce up-regulation of C/EBPa (CCAAT-enhancer-binding proteins a). C/EBP acan further compete with NF1A and promote miR-223 expression [5,6]. The expression of miR-223 was then reported to market granulocytic differentiation [8]. The abnormal signal pathway activation is essential in tumor and leukemia cell development. This contains PI3K/Akt, mTOR(mammalian target of rapamycin), ERK/MAPK, STAT3/5, NF-kB, protein kinase C [9,10] and Wnt/b-cateninPLoS 1 | plosone.org[11] at the same time as insulin-like growth factor-1 receptor (IGF-1R) signal pathway. IGF-1R system is comprised of two ligands (IGF-1,2); three cellular membrane-spanning receptors IGF-1 receptor (IGF1R), insulin receptor, and IGF-2R; and six high-affinity IGFbinding proteins IGFBP1-6, playing the pivotal function in standard development and development with the cells [12]. Immediately after IGF-1 binding to IGF-1R, the signal pathway PI3K/Akt and mTOR are activated to regulate cell proliferation, and are also activated in tumor cells such as acute myeloid leukemia [11]. Once activated, the signaling through Akt is usually propagated to a diverse array of substrates such as mTOR, a essential regulator of protein translation. This pathway is definitely an appealing therapeutic target in cancer remedy because it serves as a convergence point for many development stimuli, and through its downstream substrates, it controls cellular processes that contribute to the initiation and maintenance of cancer [13]. Having said that, the detailed mechanisms of miR-223 in differentiation or tumor progression still stay unclear. The functions of miR-223 in earlier reports were not clear or somewhat contradicted in both hematopoietic and non-hematopoietic systems. Though miR-223 was thought to market differentiation, some documents reported that miR-223 negatively regulates granulocyte differentiation in miR-223-/Y transgenic mice [14]. It was also reported that miR-223 was significantly up-regulated inMiR-223 Targets IGF-1Rbladder cancer [15] and recurrent ovarian cancer [16]. In hepatocellular carcinoma cells (HCC) miR-22.
