Viperin interacts with PEX19 to mediate peroxisomal augmentation of the innate antiviral responseThis work highlights the multifunctional role of the ISG viperin and its interaction with the peroxisomal protein Pex19 to modulate peroxisomal-dependent innate signaling that ultimately restricts viral infection.
A multifaceted role of progranulin in regulating amyloid-beta dynamics and responsesProgranulin deficiency leads to decreased levels of human APP and Aβ in a sex- and age-dependent manner and enhanced inflammatory and lysosomal responses in the plaque-associated microglia.
Specific N-cadherin–dependent pathways drive human breast cancer dormancy in bone marrowCDH2 is required for connexin 43 (Cx43)–mediated gap junction intercellular communication between breast cancer cells and bone marrow niche cells to achieve dormancy and chemoresistance.
Gametic specialization of centromeric histone paralogs in Drosophila virilisSomatic and germline centromeric functions could differ because of different chromatin environments in male and female gametes versus somatic cells. We show that two different centromeric histone paralogs are alternately retained in male versus female gametes in many Drosophila species.
Mitochondrial Aurora kinase A induces mitophagy by interacting with MAP1LC3 and Prohibitin 2The multifunctional Ser/Thr kinase AURKA uses the Inner Mitochondrial Membrane receptor PHB2 and MAP1LC3 as a signalling platform to orchestrate the elimination of dysfunctional mitochondria.
Replicated chromatin curtails 53BP1 recruitment in BRCA1-proficient and BRCA1-deficient cellsThis study demonstrates how single cell normalization to genome size provides insight into genome function, here in the context of DNA double-strand break repair by 53BP1 versus BRCA1–BARD1.
The AXL-PYK2-PKCα axis as a nexus of stemness circuits in TNBCA clinically relevant AXL-PYK2-PKCα axis where PYK2 and PKCα act as signaling nodes and functionally cooperate to converge stemness promoting pathways and regulate Oct4 and Nanog pluripotent TFs.
Cancer-associated cells release citrate to support tumour metastatic progressionCancer-associated stroma is recruited by cancer cells to synthesise and release citrate necessary to support metastatic progression of the disease.
LRRK2-phosphorylated Rab10 sequesters Myosin Va with RILPL2 during ciliogenesis blockadePathogenic LRRK2 phosphorylation of Rab10 GTPase dramatically redistributes Myosin Va and RILPL2 proteins to the mother centriole and sequesters Myosin Va at that location in a manner that likely interferes with its role in ciliogenesis.
Dendritic cell entry to lymphatic capillaries is orchestrated by CD44 and the hyaluronan glycocalyxCD44 anchors the hyaluronan glycocalyx on migrating dendritic cells to permit docking to the endothelial receptor LYVE-1, thus orchestrating lymphatic trafficking through modulating glycocalyx density.
