Temporal and Cell‐Specific Regulation of Synaptic Homeostasis by the Chromatin Remodeler Chd1

open access: yesAdvanced Science, EarlyView.
Chd1, the Drosophila homologue of mammalian CHD2 ‐ a gene linked to autism, epilepsy, and intellectual disability, is required for synaptic homeostatic plasticity. Chd1 in glia is necessary for the rapid induction of synaptic homeostasis, whereas Chd1 in motoneurons, muscle, and glia is critical for long‐term maintenance.

Pairing of competitive and topologically distinct regulatory modules enhances patterned gene expression

open access: yesMolecular Systems Biology, 2008
Biological networks are inherently modular, yet little is known about how modules are assembled to enable coordinated and complex functions. We used RNAi and time series, whole‐genome microarray analyses to systematically perturb and characterize ...

Crops gone wild: evolution of weeds and invasives from domesticated ancestors. [PDF]

open access: yes, 2010
The evolution of problematic plants, both weeds and invasives, is a topic of increasing interest. Plants that have evolved from domesticated ancestors have certain advantages for study.

Mallard Hybridization With Domesticated Lineages Alters Spring Migration Behavior and Timing

open access: yesEcology and Evolution
ABSTRACTIntrogressive hybridization, the interbreeding and gene flow between different species, has become increasingly common in the Anthropocene, where human‐induced ecological changes and the introduction of captively reared individuals are increasing secondary contact among closely related species, leading to gene flow between wild and domesticated

Telomere‐to‐Telomere Genomes Reveal that Multiscale Evolution Shapes the Largest Metabolic Arsenal of Diaporthe Fungi

open access: yesAdvanced Science, EarlyView.
This study presents the first telomere‐to‐telomere genomes and population resources for Diaporthe pathogens, uncovering the largest known fungal repertoire of secondary metabolite gene clusters. Structural variations and horizontal gene transfer drive cluster diversification, while specific rapidly evolving clusters control virulence, offering novel ...

Hybrid phenotypes and lineage promiscuity in acute leukemia.

open access: yesHaematologica, 1991
Clinical data indicate that AL are heterogeneous diseases with variable responsiveness to chemotherapeutic agents. Based on this evidence, the efforts of most investigators are aimed at providing rapid identification of AL features predictive of distinct prognostic outcomes.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Systems genetic analysis of osteoblast-lineage cells.

open access: yesPLoS Genetics, 2012
The osteoblast-lineage consists of cells at various stages of maturation that are essential for skeletal development, growth, and maintenance. Over the past decade, many of the signaling cascades that regulate this lineage have been elucidated; however ...
