Detailed molecular characterization of a constitutively active bacterial NADPH oxidase (NOX) provides clues to the activation mechanism required to trigger electron transfer and reactive oxygen species (ROS) production in tightly regulated eukaryotic NOX.

The Notch signaling pathway can use its various ligands, receptors, and Fringe proteins to generate diverse intra- and intercellular signaling behaviors.
Genetic disruption of sodium-hydrogen exchanger 6 (NHE6) reduces amyloid plaques in humanized Alzheimer's disease mouse models and restores normal synaptic responses to neuromodulatory input in humanized ApoE4-expressing animals.
The genome sequence of Trichoplusia ni enables the use of this widespread lepidopteran pest as a model for both the study of small RNA pathways and insecticide resistance.

Hypertrophic chondrocytes of the growth plate undergo a process of dedifferentiation to generate marrow associated skeletal stem and progenitor cells (SSPCs), which ultimately re-differentiate into cells of the osteoblast or adipocyte lineages during skeletal development.

B-cells generate inner actomyosin foci from lamellipodial actin networks to drive cell contraction on antigen-presenting surfaces, which causes signaling molecule disassociation from B-cell receptor clusters and signal attenuation.

In silico modeling identify allosteric CXCR4 modulators that block receptor nanoclustering and chemoattractant sensing without affecting other CXCL12-mediated functions, and reduce tumorigenesis and metastasis in a zebrafish model.
SRSF10 directly binds genes functioning in spermatogonia and regulates their alternative splicing, the defect of which can lead to progenitor expansion failure.
