- Requirement of DNMT1 to orchestrate epigenomic reprogramming for NPM-ALK–driven lymphomagenesis
NPM-ALK–driven lymphoma in mice is dependent on MYC signaling and epigenomic reprogramming via DNA methyltransferases, resulting in heterogenous DNA methylation signatures reminiscent of human lymphoma.
- Sustained Helicobacter pylori infection accelerates gastric dysplasia in a mouse model
Hp infection was found to alter metaplasia and accelerate dysplasia in mice. Thus, Hp can promote gastric preneoplastic progression, in addition to its known role in initiating chronic inflammation.
- ESI mutagenesis: a one-step method for introducing mutations into bacterial artificial chromosomes
A simple and efficient recombineering-based method for introducing point mutations into bacterial artificial chromosomes using an artificial intron cassette.
- SCFCdc4 ubiquitin ligase regulates synaptonemal complex formation during meiosis
During meiosis, homologous chromosomes pair to form the synaptonemal complex (SC). This study showed that SCFCdc4 ubiquitin ligase is required for and works with Pch2 AAA+ ATPase for SC assembly.
- Meningeal lymphoid structures are activated under acute and chronic spinal cord pathologies
We found that acute insult to the central nervous system induces the formation of lymphocyte aggregates reminiscent of tertiary lymphoid structures within the spinal cord meninges. Unlike draining CNS-cervical lymph nodes, meningeal lymphocytes are locally activated during neuro-inflammtion and neurodegeneration.
- Wnt10b-GSK3β–dependent Wnt/STOP signaling prevents aneuploidy in human somatic cells
Autocrine Wnt10b signaling ensures proper mitotic microtubule polymerization and faithful chromosome segregation.
- Scratch-induced partial skin wounds re-epithelialize by sheets of independently migrating keratinocytes
Intravital microscopy of scratch wounds in the murine skin reveals that individual basal keratinocytes migrate in a swarming fashion towards the wound to bypass intact hair follicles, thereby facilitating fast repair.
- Inhibiting the reproduction of SARS-CoV-2 through perturbations in human lung cell metabolic network
Using genomic and structural information from SARS-CoV-2, we created a biomass function capturing its amino and nucleic acid requirements and incorporated this into a metabolic model of the human lung cell to predict metabolic perturbations that inhibit virus reproduction.
- BRD2 regulation of sigma-2 receptor upon cholesterol deprivation
Upon cholesterol deprivation, epigenetic bookmark reader BRD2 and master transcription factor SREBP2 form a complex at bookmarked chromatin (H3K27ac), thereby activating the transcription of the sigma-2 receptor—a recently unveiled player in cholesterol homeostasis.
- G-CSF shifts erythropoiesis from bone marrow into spleen in the setting of systemic inflammation
Granulocyte colony-stimulating factor suppresses erythropoiesis of bone marrow and promotes splenic erythropoiesis during lipopolysaccharide-induced systemic inflammation in mice.
