Molecular characterization of Chlamydomonas reinhardtii telomeres and telomerase mutantsThis study characterizes the sequence, end structure, and length distribution of Chlamydomonas reinhardtii telomeres and shows that telomerase mutants are defective in telomere maintenance.
Mesenchymal stromal cell activation by breast cancer secretomes in bioengineered 3D microenvironmentsThis study shows the activation of tumour-associated mesenchymal stromal cells by breast cancer secretomes in bioengineered 3D microenvironments using comprehensive multiomics analysis methods.
Robust repression of tRNA gene transcription during stress requires protein arginine methylationThis work examines how protein arginine methylation of Rpc31, a subunit of RNA Pol III, promotes negative regulation of tRNA biogenesis in the context of cellular stress.
Opposing functions of F-BAR proteins in neuronal membrane protrusion, tubule formation, and neurite outgrowthNeurite formation is a fundamental antecedent to axon and dendrite formation, but the mechanisms that underlie this important process are poorly characterized. Here, we demonstrate that two F-BAR proteins, CIP4 and FBP17, have opposing functions in early cortical neuron development.
ATP hydrolysis by KaiC promotes its KaiA binding in the cyanobacterial circadian clock systemATP hydrolysis in the KaiC hexamer triggers the exposure of its C-terminal segments into the solvent so as to capture KaiA, providing mechanistic insights into the circadian periodicity regulation.
The S. Typhi effector StoD is an E3/E4 ubiquitin ligase which binds K48- and K63-linked diubiquitinSalmonella Typhi is estimated to cause 100,000–200,000 deaths annually, yet its infection strategy remains elusive. This article reports of the first Typhi-specific effector, which has an E3/E4 ubiquitin ligase activity and can uniquely bind K48- and K63-linked diubiquitin.
PKAc is not required for the preerythrocytic stages of Plasmodium bergheiThe mutant salivary gland sporozoites lacking PKAc are able to glide, invade hepatocytes, and mature into hepatic merozoites, which release successfully from the merosome, however, fail to initiate blood stage infection when inoculated into mice.
The m6A pathway protects the transcriptome integrity by restricting RNA chimera formation in plantsThis study reveals that an m6A-assisted polyadenylation pathway comprising conserved m6A writer proteins and a plant-specific m6A reader contributes to transcriptome integrity in Arabidopsis thaliana by restricting RNA chimera formation at rearranged loci.
Tumor-intrinsic response to IFNγ shapes the tumor microenvironment and anti–PD-1 response in NSCLCUsing an immunocompetent mouse model of NSCLC, this study demonstrates that tumor-intrinsic response to IFNγ determines response to anti–PD-1 through alterations in the tumor microenvironment.
