    Characterisation of the biflavonoid hinokiflavone as a pre-mRNA splicing modulator that inhibits SENP

    Andrea Pawellek, Ursula Ryder ... Angus I Lamond
    Hinokiflavone is identified as a splicing modulator that blocks progression from spliceosome complex A to complex B and inhibits SUMO protease SENP1, causing hyper-SUMOylation affecting 6 U2 snRNP proteins.

    Proteomic analysis of the response to cell cycle arrests in human myeloid leukemia cells

    Tony Ly, Aki Endo, Angus I Lamond
    Building on previous work (Ly et al., 2014), we show that elutriated cells and arrested cells have similar patterns of DNA content and cyclin expression: however, a large fraction of the proteome changes detected in arrested cells are found to reflect arrest-specific responses rather than physiological cell cycle regulation.

    Independent theta phase coding accounts for CA1 population sequences and enables flexible remapping

    Angus Chadwick, Mark CW van Rossum, Matthew F Nolan
    Independent coding without synaptic coordination explains complex sequences of population activity observed during theta states and maximizes the number of distinct environments that can be encoded through population theta sequences.

    Bayesian inference of population prevalence

    Robin AA Ince, Angus T Paton ... Philippe G Schyns
    Bayesian estimation of the proportion of the population that would show an effect in an experiment provides a broadly applicable alternative to standard null hypothesis tests on the population mean with several advantages.

    Proteomic analysis of cell cycle progression in asynchronous cultures, including mitotic subphases, using PRIMMUS

    Tony Ly, Arlene Whigham ... Angus I Lamond
    A detailed analysis of protein abundance and phosphorylation changes across mitotic subphases and interphase in asynchronously growing human cells has been enabled by combining FACS with quantitative MS-based proteomics.

    A proteomic chronology of gene expression through the cell cycle in human myeloid leukemia cells

    Tony Ly, Yasmeen Ahmad ... Angus I Lamond
    Quantitative analysis of protein and mRNA expression across a minimally perturbed cell cycle in human myeloid cells has identified myeloid-specific and cell cycle-regulated gene expression, including examples of isoform- and phosphorylation-specific regulation, with all data made available in a searchable, online database.

    Physical determinants of vesicle mobility and supply at a central synapse

    Jason Seth Rothman, Laszlo Kocsis ... Robin Angus Silver
    Hydrodynamic and steric interactions slow vesicle mobility and are predicted to ultimately limit vesicle supply to the active zone during sustained high-frequency signalling at a central synapse.

    Parallel evolution of Pseudomonas aeruginosa phage resistance and virulence loss in response to phage treatment in vivo and in vitro

    Meaghan Castledine, Daniel Padfield ... Angus Buckling
    Parallel evolutionary dynamics were found in vivo and in vitro, showing that laboratory studies can be predictive of certain phenotypic outcomes of clinical phage therapy (phage-mediated decolonization).

    Proteomic and functional comparison between human induced and embryonic stem cells

    Alejandro J Brenes, Eva Griesser ... Angus I Lamond
    Human induced pluripotent stem cells and embryonic stem cells express a similar set of proteins, but the levels of cytoplasmic and mitochondrial proteins vary, with concomitant effects on phenotypes including transport and mitochondrial function.

    The biological function of an insect antifreeze protein simulated by molecular dynamics

    Michael J Kuiper, Craig J Morton ... Angus Gray-Weale
    Simulations of the biological function of an antifreeze protein reveal its molecular interactions with the ice/water interface.
