    Water-mediated recognition of t1-adenosine anchors Argonaute2 to microRNA targets

    Nicole T Schirle et al.
    Argonaute proteins directly contact adenosine nucleotides in some miRNA target sites, leading to enhanced repression of the target mRNA.

    Viral-inducible Argonaute18 confers broad-spectrum virus resistance in rice by sequestering a host microRNA

    Jianguo Wu et al.
    The cooperative antiviral activity of two distinct AGO proteins could be exploited to provide a new strategy for controlling viral diseases in rice.

    RISC-interacting clearing 3’- 5’ exoribonucleases (RICEs) degrade uridylated cleavage fragments to maintain functional RISC in Arabidopsis thaliana

    Zhonghui Zhang et al.
    AGO protein-interacting exoribonucleases clear RNA induced silencing complex (RISC)-resulting 5' cleavage products in time to recycle RISC and miRNAs.

    The MBD7 complex promotes expression of methylated transgenes without significantly altering their methylation status

    Dongming Li et al.
    The METHYL-CpG-BINDING DOMAIN 7 (MBD7) complex promotes the activation (rather than repression) of transgenes that undergo DNA methylation and it does so without significantly altering their methylation status, placing this complex downstream of DNA methylation.

    Domestic chickens activate a piRNA defense against avian leukosis virus

    Yu Huining Sun et al.
    To protect the germ line genome, chickens acquire new small RNA-based immune defense in response to recently endogenized retroviruses by turning a truncated provirus into a weapon.

    miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway

    Taichi Isobe et al.
    Insights into the roles and mechanisms of two of the miRNAs upregulated in human breast cancer stem cells in at least some breast cancers are presented.

    Ovaries absent links dLsd1 to HP1a for local H3K4 demethylation required for heterochromatic gene silencing

    Fu Yang et al.
    A Drosophila fertility gene is identified that acts as a linker between HP1a and local H3K4 demethylation during HP1a-mediated gene silencing that is required for ovary development and transposon silencing..

    Importance of miRNA stability and alternative primary miRNA isoforms in gene regulation during Drosophila development

    Li Zhou et al.
    Selective degradation of mature miRNAs shapes temporal miRNA expression patterns and is important for proper regulation of target genes to support normal development of Drosophila embryos.
