    Circadian RNA expression elicited by 3’-UTR IRAlu-paraspeckle associated elements

    Manon Torres et al.
    Circadian gene expression can be driven by a post-transcriptional mechanism involving circadian mRNA nuclear retention by paraspeckle nuclear bodies.

    RNA structures that resist degradation by Xrn1 produce a pathogenic Dengue virus RNA

    Erich G Chapman et al.
    The Dengue virus contains discretely folded RNA structures that confer the ability to resist a powerful host cell enzyme and produce a disease-inducing noncoding RNA.

    Polypyrimidine tract binding protein 1 protects mRNAs from recognition by the nonsense-mediated mRNA decay pathway

    Zhiyun Ge et al.
    The RNA-binding protein PTBP1 is recruited to sites near stop codons in retroviral and human mRNAs, shielding them from detection and degradation by the nonsense-mediated mRNA decay pathway.

    Increasing Notch signaling antagonizes PRC2-mediated silencing to promote reprograming of germ cells into neurons

    Stefanie Seelk et al.
    Increased Notch signaling enhances germ cell reprograming in C. elegans by antagonizing PRC2-mediated repression, which results in the activation of UTX-1 and other reprograming-promoting genes.

    Differential 3’ processing of specific transcripts expands regulatory and protein diversity across neuronal cell types

    Saša Jereb et al.
    Differential expression of 3'UTR isoforms expands regulatory and protein diversity in cerebellar Purkinje and granule cells and during granule cell development.

    Science Forum: Challenges in validating candidate therapeutic targets in cancer

    Jeffrey Settleman et al.
    More than 30 published articles have suggested that a protein kinase called MELK is an attractive therapeutic target in human cancer, but three recent reports describe compelling evidence that it is not.
  1. Research: Decoupling of the minority PhD talent pool and assistant professor hiring in medical school basic science departments in the US

    Kenneth D Gibbs Jr et al.
    A systems-level analysis of the biomedical workforce in the US shows that current strategies to enhance faculty diversity are unlikely to have a significant impact, and that there is a need to increase the number of PhDs from underrepresented minority backgrounds who move on to postdoctoral positions.
