    Hepatitis B virus core protein allosteric modulators can distort and disrupt intact capsids

    Christopher John Schlicksup et al.
    Small molecule antivirals that drive assembly of HBV capsid protein can also bind to pre-assembled capsids causing them to change morphology or even break, suggesting a complex transduction of binding effects across the capsid.

    An excitatory lateral hypothalamic circuit orchestrating pain behaviors in mice

    Justin N Siemian et al.
    A small population of lateral hypothalamic neurons detects pain and can be activated to suppress pain-related behavioral adaptations and the unpleasantness associated with pain in mice.

    The insulin/IGF signaling cascade modulates SUMOylation to regulate aging and proteostasis in Caenorhabditis elegans

    Lorna Moll et al.
    By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.

    Distinct signals in medial and lateral VTA dopamine neurons modulate fear extinction at different times

    Lili X Cai et al.
    Dopamine neurons in medial versus lateral VTA encode different signals during fear extinction, yet inhibition of both populations influences fear extinction, at different times.

    Regulatory polymorphisms modulate the expression of HLA class II molecules and promote autoimmunity

    Prithvi Raj et al.
    Genetic variations that underlie common autoimmune disease genes are predominantly regulatory and modify the expression of multiple genes within the HLA gene complex and throughout the immune system.

    Mitochondrial dysfunction remodels one-carbon metabolism in human cells

    Xiaoyan Robert Bao et al.
    Mitochondrial respiratory chain dysfunction inhibits mitochondrial one-carbon metabolism, impairing cellular nucleotide biosynthesis.

    The transcriptional cofactor TRIM33 prevents apoptosis in B lymphoblastic leukemia by deactivating a single enhancer

    Eric Wang et al.
    TRIM33 performs an essential function in B cell acute lymphoblastic leukemia through an association with a single cis element.

    Chromatin-associated RNA sequencing (ChAR-seq) maps genome-wide RNA-to-DNA contacts

    Jason C Bell et al.
    ChAR-seq is a massively parallelized de novo RNA mapping assay, which is capable of generating hundreds to thousands of RNA-binding maps with no a priori knowledge of target RNAs.

    An integrative genomic analysis of the Longshanks selection experiment for longer limbs in mice

    João PL Castro et al.
    Genome sequencing of mice selected for longer limbs reveals that rapid selection response is due to both discrete loci and polygenic adaptation.

    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner et al.
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.
