Abstract:
microRNAs (miRNAs) play critical roles in many different cellular processes, including metabolism, apoptosis, differentiation and development. We showed miR-181b to be highly expressed in acute myeloid leukemia (AML). Furthermore, miR-181b contributed to proliferation of AML cells by targeting MLK2. Our results demonstrated that miR-181b plays an important role in the biology of AML and may be useful in developing therapies targeting miRNAs.

MicroRNAs
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
