    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.

    Development of Bag-1L as a therapeutic target in androgen receptor-dependent prostate cancer

    Laura Cato et al.
    Targeting the activation of the androgen receptor N-terminal domain by the cochaperone Bag-1L provides a new approach for inhibiting androgen receptor function to treat prostate cancer.

    Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE

    Yao Li et al.
    A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.

    LAST, a c-Myc-inducible long noncoding RNA, cooperates with CNBP to promote CCND1 mRNA stability in human cells

    Limian Cao et al.
    A c-Myc-transcribed long noncoding RNA namely LAST (LncRNA-assisted stabilization of transcripts) collaborates with a cellular factor CNBP to promote the stability of CCND1/cyclin D1 mRNA post-transcriptionally, ensuring the proper G1/Sphase transition of the cell cycle.

    Altered corticolimbic connectivity reveals sex-specific adolescent outcomes in a rat model of early life adversity

    Jennifer A Honeycutt et al.
    Early life adversity led to hyper-innervation from the basolateral amygdala to the prefrontal cortex earlier in females than males and disrupted maturation of functional connectivity, which predicted anxiety-like outcomes.

    Mechanics and kinetics of dynamic instability

    Thomas CT Michaels et al.
    A theoretical framework for the growth of microtubules quantifies the roles of geometry, mechanics, kinetics and randomness and provides a phase diagram for dynamic instability in these self-assembled polymers.

    CatSperζ regulates the structural continuity of sperm Ca2+ signaling domains and is required for normal fertility

    Jean-Ju Chung et al.
    A new component, CatSper zeta, is required for continuous alignment of the calcium channel along the sperm's tail and is crucial for normal sperm swimming behavior and fertility.

    Robust and distributed neural representation of action values

    Eun Ju Shin et al.
    Action-value signals previously found in many brain areas can be accounted for neither by concurrent serial correlations in neural activity and action value nor by signals for other decision variables.

    Molecular mechanism of activation-triggered subunit exchange in Ca2+/calmodulin-dependent protein kinase II

    Moitrayee Bhattacharyya et al.
    Closed-ring and open-spiral assembly of the multi-subunit neuronal kinase CaMKII suggest a mechanism for how active subunits shuttle between individual assemblies, propagating stimulatory signals.

    Clathrin coat controls synaptic vesicle acidification by blocking vacuolar ATPase activity

    Zohreh Farsi et al.
    Parallel measurements of pH gradient and membrane potential at the single vesicle level have revealed that the synaptic vesicle acidification is initiated by removal of its clathrin coat, which blocks vesicular ATPase activity.
