Establishment of a coculture system for Porphyromonas gingivalis and head and neck squamous cell carcinoma using spheroid culture and LATS inhibition

open access: yesFEBS Open Bio, EarlyView.
We established a spheroid coculture system enabling viable Porphyromonas gingivalis–HNSCC interactions under normoxic conditions. Inhibition of LATS1/2 maintains tumor cells in an undifferentiated state, which may promote spheroid growth and create a more permissive environment for bacterial persistence.

Synergistic interaction network between the snR30 RNP, Utp23, and ribosomal RNA during ribosome synthesis

open access: yesRNA Biology, 2022
snR30/U17 is a highly conserved H/ACA RNA that is required for maturation of the small ribosomal subunit in eukaryotes. By base-pairing to the expansion segment 6 (ES6) of 18S ribosomal RNA (rRNA), the snR30 H/ACA Ribonucleoprotein (RNP) indirectly ...

Domain associated with zinc fingers‐containing NF90‐NF45 complex inhibits m6A modification of primary microRNA by suppressing METTL3/14 activity

open access: yesFEBS Open Bio, EarlyView.
NF90–NF45 functions as a negative regulator of methyltransferase‐like 3/14 (METTL3/14)‐mediated N6‐methyladenosine (m6A) modification on primary microRNAs (pri‐miRNAs). NF90–NF45 binds to anti‐oncogenic pri‐miRNAs and inhibits their m6A modification, thereby suppressing the biogenesis of anti‐oncogenic miRNAs.

5′‐Cleavage site of D. melanogaster 18 S rRNA

open access: yesFEBS Letters, 1984
We determined the nucleotide sequence of the DNA region around the 5′‐terminus of 18 S rRNA in two cloned rDNA gene units of Drosophila melanogaster. The 5′‐base is within a sequence CATTATT which is present also at the 3′‐terminus of the 18 S rRNA coding region. In this case it is known that the situation is CATTA3′ · TT.

Origin of the Mesozoa inferred from 18S rRNA gene sequences [PDF]

open access: yesMolecular Biology and Evolution, 1996
The phylum Mesozoa comprises small, simply organized wormlike parasites of marine invertebrates and is composed of two classes, the Rhombozoa and the Orthonectida. The origin of Mesozoa is uncertain; they are classically considered either as degenerate turbellarians or as primitive multicellular animals related to ciliated protists.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Arabidopsis RIBOSOMAL RNA PROCESSING7 Is Required for 18S rRNA Maturation [PDF]

open access: yesThe Plant Cell, 2018
Ribosome biogenesis is fundamental to growth and development in eukaryotes and is linked to human diseases and cancer. Arabidopsis thaliana MORPHOLOGY OF ARGONAUTE1-52 SUPPRESSED 2 (MAS2) participates in splicing and 45S ribosomal DNA (rDNA) expression.

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Maturation of the 90S pre-ribosome requires Mrd1 dependent U3 snoRNA and 35S pre-rRNA structural rearrangements [PDF]

open access: yes, 2018
In eukaryotes, ribosome biogenesis requires folding and assembly of the precursor rRNA (pre-rRNA) with a large number of proteins and snoRNPs into huge RNA-protein complexes. In spite of intense genetic, biochemical and high-resolution cryo-EM studies in
