    A novel inhibitory nucleo-cortical circuit controls cerebellar Golgi cell activity

    Lea Ankri, Zoé Husson ... Marylka Yoe Uusisaari
    The glycinergic neurons of the cerebellar nuclei project extensively to the cerebellar cortex and inhibit GABAergic Golgi cells.

    Quantitative and functional interrogation of parent-of-origin allelic expression biases in the brain

    Julio D Perez, Nimrod D Rubinstein ... Catherine Dulac
    A subset of genes in the mouse brain show dynamically regulated and unequal expression of maternally and paternally derived variants, with implications for brain development and function.

    Cell type-specific transcriptomics of hypothalamic energy-sensing neuron responses to weight-loss

    Fredrick E Henry, Ken Sugino ... Scott M Sternson
    Cell type-specific transcriptomics in energy homeostasis neurons has identified hundreds of genes and multiple signaling pathways that are regulated by weight loss in mice, as well as several previously unexamined genes that can regulate appetite and body weight.

    A forward genetic screen reveals novel independent regulators of ULBP1, an activating ligand for natural killer cells

    Benjamin G Gowen, Bryan Chim ... David H Raulet
    Forward genetic screening has provided insight into the molecular mechanisms and stress pathways that promote tumor cell recognition by natural killer cells.

    Stepwise nucleosome translocation by RSC remodeling complexes

    Bryan T Harada, William L Hwang ... Xiaowei Zhuang
    Single molecule FRET reveals that the SWI/SNF-family remodeling enzyme RSC translocates nucleosomes along the DNA in steps of ~1-2 base pairs in size.

    Signal transducer and activator of transcription 5 (STAT5) paralog dose governs T cell effector and regulatory functions

    Alejandro Villarino, Arian Laurence ... John J O'Shea
    Asymmetrical expression dictates functional dominance of one STAT5 paralog at cellular and tissue levels despite redundancy at molecular and genomic levels.

    Sam68/KHDRBS1 is critical for colon tumorigenesis by regulating genotoxic stress-induced NF-κB activation

    Kai Fu, Xin Sun ... Fengyi Wan
    The nuclear protein Sam68 plays a role in the genotoxic stress-initiated "nuclear to cytoplasmic" activation of NF-κB and is involved in the development and survival of colon cancer.
