    PDE2A2 regulates mitochondria morphology and apoptotic cell death via local modulation of cAMP/PKA signalling

    Stefania Monterisi et al.
    The enzyme phosphodiesterase 2A2 localises at the mitochondrial membrane and its inhibition results in a local increase in cAMP concentration, mitochondrial elongation and resistance to apoptosis.

    cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool

    Vladimir Camarena et al.
    cAMP is identified to play a novel role in regulating DNA demethylation and gene transcription by augmenting the intracellular reactive Fe(II) pool.

    Differences and similarities between human and chimpanzee neural progenitors during cerebral cortex development

    Felipe Mora-Bermúdez et al.
    Neural progenitors in humans and chimpanzee organoids show remarkably similar cellular and molecular parameters, but metaphase is longer during human mitosis.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

    G protein-regulated endocytic trafficking of adenylyl cyclase type 9

    André M Lazar et al.
    An adenylyl cyclase isoform is shown to dynamically traffic to endosomes after activation by G protein in mammalian cells, contributing to cellular cAMP signaling by internalized GPCRs.

    Reciprocal regulation of ARPP-16 by PKA and MAST3 kinases provides a cAMP-regulated switch in protein phosphatase 2A inhibition

    Veronica Musante et al.
    A complex interplay between MAST3 and PKA protein kinases and the regulatory protein ARPP-16 allows cAMP to control the activity of protein phosphatase 2A.

    Activation of PTHrP-cAMP-CREB1 signaling following p53 loss is essential for osteosarcoma initiation and maintenance

    Mannu K Walia et al.
    The loss of p53 in bone cells activates critical signaling pathways; these are also essential in bone cancer.

    Dual roles for ATP in the regulation of phase separated protein aggregates in Xenopus oocyte nucleoli

    Michael H Hayes et al.
    The equilibrium between solubility and aggregation of proteins in the nucleus is controlled by co-aggregates like RNA and the action of ATP as both an energy source and a destabilizing chemical agent.

    3.3-Å resolution cryo-EM structure of human ribonucleotide reductase with substrate and allosteric regulators bound

    Edward J Brignole et al.
    Cryo-electron microscopy structures of human ribonucleotide reductase reveal molecular details of substrate selection and allosteric inhibition through assembly of its large subunit into a ring that excludes its small subunit.

    Ligand discrimination and gating in cyclic nucleotide-gated ion channels from apo and partial agonist-bound cryo-EM structures

    Jan Rheinberger et al.
    High resolution SthK channel cryo-EM structures in different ligand-bound states combined with single-channel functional data in the same conditions constrain a gating mechanism for CNG channels.
