ProteomicsOuter Membrane Vesicles Secreted by Bacteroides fragilis Inhibit CFTR Chloride Secretion by Human Colon Organoids
The goals of this study were to develop a model to study host pathogen interactions in primary human colon organoids and to test the hypothesis that Bacteroides fragilis toxin (BFT-2) secreted in outer membrane vesicles (OMVs) modulates mucosal immunity and CFTR Cl- secretion. Since Bacteroides spec...

ProteomicsMALDI-MSI-guided LCM-MS: Advancing spatial multi-omics in mouse brain tissue
Spatial multi-omics involves the analysis of biomolecules such as proteome, metabolome, and lipidome within their native spatial context in tissues or cells. This approach provides a comprehensive understanding of biomolecular networks in specific biological environments. Mass spectrometry imaging (...

ProteomicsAn rRNA fragment in extracellular vesicles secreted by human airway epithelial cells increases the fluoroquinolone sensitivity of P. aeruginosa
Extracellular vesicles (EVs) secreted by human airway epithelial cells contain small RNAs that are transferred to P. aeruginosa upon EV exposure. The purpose of this experiment was to characterize the effect of a 27-nucleotide long human 18S rRNA external transcribed spacer fragment on P. aeruginosa...

ProteomicsSPT6 functions in transcriptional pause/release via PAF1C recruitment
In vitro studies identified various factors including P-TEFb, SEC, SPT6, PAF1, DSIF, and NELF functioning at different stages of transcription elongation driven by RNA polymerase II (RNA Pol II). What remains unclear is how these factors cooperatively regulate pause/release and productive elongation...

ProteomicsCalpain activity is regulated by a KCTD7–cullin 3 complex via non-degradative ubiquitination
Calpains are a class of non-lysosomal cysteine proteases that exert their regulatory functions via limited proteolysis of their substrates. Similar to the lysosomal and proteasomal systems, calpain dysregulation is implicated in the pathogenesis of neurodegenerative disease and cancer. Despite inten...

ProteomicsEvolution of the Umbilical Cord Blood Proteome Across Gestational Development
Neonatal health is dependent on early risk stratification, diagnosis, and timely management of many potentially devastating conditions. Preterm infants are at increased risk of prematurity-related complications, including: early-onset sepsis, chronic lung disease, intraventricular hemorrhage, necrot...

ProteomicsSpatial proteomics of Onchocerca volvulus with pleomorphic neoplasms show local and systemic dysregulation of protein expression
Onchocerca volvulus is the agent of onchocerciasis or river blindness and targeted by WHO for elimination. The main strategy is mass drug administration with ivermectin for the duration of the life span of the adult worms. The drug is mainly microfilaricidal, but weak macrofilaricidal effects, after...

Cholangiocarcinoma (CC) is an aggressive tumor that shows a poor survival rate even after resection. The present study aimed at identification of the genome-wide expressed genes related to CC oncogenesis and its sarcomatous transdifferentiation using DNA microarray technology. The differentially exp...
