Knowing more life process and disease types associated with miR-155-5 p,which could provide a theoretical basis for the further function study of hsa-miR-155-5 p. Bioinformatics analysis of miR-155-5 p found that the mature sequence of miR-155-5 p was highly conservative property among various species. GO analysis showed that the molecular functions of the target genes were significantly invovled in heterocyclic compound binding,nucleic acid binding,and so on;These genes were significantly associated with cellular macromolecule metabolic process,biological regulation,organic substance metaboli...
