MetabolomicsA mitochondrial NADPH-cholesterol axis regulates extracellular vesicle biogenesis to support hematopoietic stem cell fate

Mitochondrial fatty acid oxidation (FAO) is essential for hematopoietic stem cell (HSC) self-renewal; however, the mechanism by which mitochondrial metabolism controls HSC fate remains unknown. Here, we show that within the hematopoietic lineage, HSCs have the largest mitochondrial NADPH pools, w...

MetabolomicsThe Impacts of Sortase A and the 4'-Phosphopantetheinyl Transferase Homolog Sfp on Streptococcus mutans Extracellular Membrane Vesicle Biogenesis

Extracellular membrane vesicles (EMVs) are produced by many Gram-positive organisms, but information regarding vesiculogenesis is incomplete. We used single gene deletions to evaluate the impacts on Streptococcus mutans EMV biogenesis of Sortase A (SrtA), which affects S. mutans...

ProteomicsWDFY2 restrains matrix metalloproteinase secretion and cell invasion by controlling VAMP3-dependent recycling
The endosomal FYVE- and WD40-domain-containing protein WDFY2 has been assigned a function as tumor suppressor, but its functional mechanism has remained elusive. Here we have used confocal, widefield and super-resolution fluorescence microscopy to show that WDFY2 localizes to the base of retromer-co...

TranscriptomicsCandidate prostate cancer genes through comparative expression-profiling of seminal vesicle
BACKGROUND: Prostate cancer is the most frequently diagnosed cancer among men in the United States. In contrast, cancer of the seminal vesicle is exceedingly rare, despite that the prostate and seminal vesicle share similar histology, secretory function, androgen dependency, blood supply, and (in p...

TranscriptomicsTranscription profiling of peripheral blood or primary finroblast cultures from choroideremia patients to determine if loss-of-function mutations in REP-1 affect intracellular vesicle transport in fibroblasts and monocytes of CHM patients
Choroideremia (CHM) is a progressive X-linked retinopathy caused by mutations in the CHM gene, which encodes Rab escort protein-1 (REP-1), an escort protein involved in the prenylation of Rabs. Under-prenylation of certain Rabs, as a result of loss of function mutations in REP-1, could affect vesicu...

ProteomicsProteomic dissection of the impact of environmental exposures on mouse seminal vesicle function
The seminal vesicles are an integral part of the male accessory gland system, and are responsible for producing a complex array of bioactive moieties that support gamete function and promote reproductive success. However, despite their physiological significance, the biology of the seminal vesicles ...

TranscriptomicsTranscription profiling of wild type and Foxa2 knock out mouse mature beta cells
The winged helix transcription factor Foxa2 regulates Pdx1 gene expression and fetal endocrine pancreas development. We show here by inducible gene ablation that Foxa2 inactivation in mature beta-cells induces hyperinsulinemic hypoglycemia in Foxa2loxP/loxP, Pdx1-CreERT2 adult mice. Mutant beta-cell...

TranscriptomicsGlobal impact of Salmonella type III secretion effector SteA on host cells
Salmonella enterica is a Gram-negative bacterium that causes gastroenteritis, bacteremia and typhoid fever in several animal species including humans. Its virulence is greatly dependent on two type III secretion systems (T3SSs), encoded in pathogenicity islands 1 (SPI1) and 2 (SPI2), respectively. T...

TranscriptomicsExosomes secreted by a nematode parasite transfer small RNAs to mammalian cells and regulate genes of the innate immune system [Heligmosomoides polygyrus]
In mammalian systems, extracellular small RNAs can operate in a paracrine manner to communicate information between cells, relying on transport within vesicles. “Foreign” small RNAs derived from bacteria, plants and parasites have also been detected in mammalian body fluids, sparking interest in whe...
