Epidermal METTL1‐Mediated m7G Modification Drives Psoriatic Inflammation by Stabilizing Bdkrb1 and Orchestrating Neutrophil Recruitment

open access: yesAdvanced Science, EarlyView.
This study unveils an unrecognized pro‐inflammatory epitranscriptomic checkpoint in psoriasis. By installing m7G modifications on the 5′ UTR of Bdkrb1 mRNA, METTL1 enhances receptor stability to orchestrate keratinocyte‐driven neutrophil recruitment via p38 MAPK signaling.

Asn-tRNA in Lactobacillus Bulgaricus is Formed by Asparaginylation of tRNA and not by Transamidation of Asp-tRNA [PDF]

open access: yesNucleic Acids Research, 1996
In many organisms (e.g., gram-positive eubacteria) Gin-tRNA is not formed by direct glutaminylation of tRNAGln but by a specific transamidation of Glu-tRNAGln. We wondered whether a similar transamidation pathway also operates in the formation of Asn-tRNA in these organisms.

Targeting Dnmt3a/m5C/RelA Axis Attenuates Microglia Inflammatory Response and Improves Postoperative Recovery in Chronic Compressive Cervical Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
A pro‐inflammatory microglial subset persists after decompression in chronic compressive cervical spinal cord injury and shows enhanced Dnmt3a‐driven m5C signaling. By stabilizing RelA mRNA, this axis sustains NF‐κB activation and postoperative neuroinflammation.

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

open access: yesAdvanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Conservation of the structures of plant tRNAs and aminoacyl‐tRNA synthetases [PDF]

open access: yesFEBS Letters, 1979
Since the determmatlon of the first nucleotlde sequence of a transfer rlbonuclelc acid (tRNAAh) in 1965 [l], almost 200 primary structures of other tRNAs have been determined [2,3] Among them tRNAs specific for phenylalanme and methlonme are of most interest The former for their easy punticatlon by benzoylated DEAE-cellulose column chromatography [4 ...

Nastává éra mezioborových didaktik?

open access: yesPedagogická Orientace, 2005
Jádrem příspěvku je myšlenka konstituování mezioborových didaktik. Jde o reakci na popsanou aktuální problematiku oborových didaktik v době rychlých kurikulárních změn, zejména při zavádění rámcových vzdělávacích programů.

CREAT: A CRISPR‐Based Genome Trimming Strategy for Systematic Identification of Dispensable Regions and Rapid Genome Reduction

open access: yesAdvanced Science, EarlyView.
Current genome‐reduction methods work in a trial‐and‐error fashion, constituting a long‐standing bottleneck in the research. We developed CREAT (CRISPR‐based genome trimming with a multi‐homology‐arm template), a CRISPR‐based genetic approach that enables systematically classifying essential versus non‐essential genomic regions and subsequently ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

open access: yesAdvanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...

Extracellular tyrosyl‐tRNA synthetase cleaved by plasma proteinases and stored in platelet α‐granules: Potential role in monocyte activation

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2020
Background Tyrosyl‐tRNA synthetase (YRS) belongs to the family of enzymes that catalyzes the tRNA aminoacylation reaction for protein synthesis, and it has been recently shown to exert noncanonical functions.
