Length polymorphism in the ribosomal DNA intergenic spacers of Lens species

Spanish Journal of Agricultural Research, 2005
Analysis of the ribosomal DNA (rDNA) intergenic spacers (IGS) (i.e., the IGS of 18S, 5.8S and 24S rDNA, and the NTS or non-transcribed spacer of 5S rDNA) of lentil cultivars and landraces (L. culinaris spp. culinaris) showed to have very low intraspecific length variability.

A Dual‐Functional Biohybrid Nanorobot to Synergistically Eradicate Biofilm and Degrade Antibiotic Resistance Genes

Advanced Science, EarlyView.
A biohybrid nanorobot integrating lytic bacteriophage N4 with Pd nanozymes is developed for targeted eradication of multidrug‐resistant E. coli biofilms. Synergistic bacterial lysis and ROS‐mediated oxidation enable simultaneous biofilm removal and antibiotic resistance genes degradation, maintaining high efficacy in complex wastewater environments ...

H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

Advanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

DMS‐MaPseq and DREEM Analyses Implicate the Critical Role of RNA Structural Dynamics in Turnip Yellow Mosaic Virus Pathogenicity

Advanced Science, EarlyView.
RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

Targeting Golgi–STING Signaling to Reprogram Innate and Adaptive Immunity for the Treatment of Implant‐Associated Infections

Advanced Science, EarlyView.
This study presents an ultrasound‐responsive nanoplatform, CS‐BT@MZ@NEs, with a BaTiO3/Mn‐Zif‐8 core and a chondroitin sulfate coating for Golgi targeting. By leveraging neutrophil hitchhiking, it enables targeted delivery to infection sites. Under ultrasound stimulation, CS‐BT@MZ@NEs generates ROS and modulates Golgi pH to activate cGAS–STING ...

Coding and spacer sequences in the 5.8S-2S region of Sciara coprophila ribosomal DNA

Nucleic Acids Research, 1980
The sequence of 436 nucleotides around the region coding for 5.8S RNA in the Sciara coprophila rDNA transcription unit (1) has been determined. Regions coding for 5.8S and 2S RNAs have been identified; they are 80 - 90% homologous to the corresponding Drosophila sequences and are separated by a 22 nucleotide long spacer.

Targeting PLD3 Reverses the Immunosuppressive Niche by Reprogramming Tumor‐Associated Macrophages and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
PLD3 activates the lysosomal‐AKT‐NF‐κB axis to drive cellular senescence in macrophages, establishing an immunosuppressive TME by limiting the infiltration of cytotoxic T, NK, and NKT cells, which confers resistance to anti‐PD‐1 therapy. Abrine inhibits PLD3 expression, restoring antitumor immunity and synergizing with anti‐PD‐1 treatment.
