Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Complement regulation: physiology and disease relevance [PDF]

open access: yesKorean Journal of Pediatrics, 2015
The complement system is part of the innate immune response and as such defends against invading pathogens, removes immune complexes and damaged self-cells, aids organ regeneration, confers neuroprotection, and engages with the adaptive immune response ...

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

open access: yesFEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Scrapie-specific pathology of sheep lymphoid tissues. [PDF]

open access: yesPLoS ONE, 2007
Transmissible spongiform encephalopathies (TSEs) or prion diseases often result in accumulation of disease-associated PrP (PrP(d)) in the lymphoreticular system (LRS), specifically in association with follicular dendritic cells (FDCs) and tingible body ...

Diagnostic and therapeutic challenges in dense deposit disease: case report

open access: yes
We report a complex case of a 15-year-old girl initially diagnosed with post-streptococcal glomerulonephritis (PSGN) but later identified as having dense deposit disease, which was initially classified as type 2 membranoproliferative glomerulonephritis ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

open access: yesFEBS Open Bio, EarlyView.
MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

Glomerular C4d Staining Does Not Exclude a C3 Glomerulopathy

open access: yesKidney International Reports, 2019
Introduction: C4d, an early product in the classical/lectin complement pathway has shown potential in the evaluation of C3 glomerulopathy where its absence would support an alternative pathway abnormality.

The Dense Deposits Disease of the Renal Basement Membranes

open access: yesKidney and Blood Pressure Research, 1980
Dense-deposits disease is characterized by an original morphological aspect of the renal basement membranes which have an electron-dense appearance. The immunofluorescence studies showed C<sub>3</sub> alone in kidney. Low serum C3 levels and the presence of C3 NF activity have been detected in this disease, demonstrating an activation of ...
