    Stem-loop and circle-loop TADs generated by directional pairing of boundary elements have distinct physical and regulatory properties

    Wenfan Ke, Miki Fujioka ... James B Jaynes
    Boundary:boundary pairing generates either stem-loop or circle-loop TADs, and these loop topologies differ in how they impact chromosome structure and genetic activities.

    Plasmodium falciparum translational machinery condones polyadenosine repeats

    Slavica Pavlovic Djuranovic, Jessey Erath ... Sergej Djuranovic
    Adaptations in protein synthesis and mRNA surveillance machinery enabled the malaria-causing parasite P. falciparum to efficiently and accurately translate long polyA nucleotide runs into long poly-lysine peptides.

    Ceapins are a new class of unfolded protein response inhibitors, selectively targeting the ATF6α branch

    Ciara M Gallagher, Carolina Garri ... Peter Walter
    Ceapins enable selective pharmacological inhibition of the cytoprotective transcriptional response to endoplasmic reticulum stress through ATF6α without affecting other branches of the unfolded protein response.

    Control of RNA viruses in mosquito cells through the acquisition of vDNA and endogenous viral elements

    Michel Tassetto, Mark Kunitomi ... Raul Andino
    Virus infection in mosquitoes initiates a highly discriminatory process in which fragments of viral RNA are reverse transcribed to create DNA copies that serve as templates of small antiviral RNAs.

    Specific lid-base contacts in the 26s proteasome control the conformational switching required for substrate degradation

    Eric R Greene, Ellen A Goodall ... Andreas Martin
    The 26S proteasome lid subcomplex acts as an external scaffold whose interactions with the ATPase motor stabilize the substrate-engagement-competent state, and control conformational changes upon engagement for subsequent degradation steps.

    Oncogenic PKA signaling increases c-MYC protein expression through multiple targetable mechanisms

    Gary KL Chan, Samantha Maisel ... John D Gordan
    Protein kinase A-driven increases in c-MYC protein expression and tumor cell proliferation can be blocked by eIF4A inhibitors, suggesting a potential new treatment option for patients with oncogenic PKA activation.

    Single-cell ‘omic profiles of human aortic endothelial cells in vitro and human atherosclerotic lesions ex vivo reveal heterogeneity of endothelial subtype and response to activating perturbations

    Maria L Adelus, Jiacheng Ding ... Casey E Romanoski
    Primary endothelial cell cultures contain markedly heterogeneous cell subtypes that exhibit distinct molecular responses to disease-relevant exposures.
