LG3 fragment of endorepellin is a possible biomarker of severity in IgA nephropathy.

IgA nephropathy (IgAN), the most common primary glomerulonephritis, is characterized by deposition of IgA in the glomerular mesangium. The diagnosis of IgAN still requires a kidney biopsy that cannot easily be repeated in the same patient during follow-up. Therefore, identification of noninvasive urinary biomarkers would be very useful for monitoring patients with IgAN.

A comparative study of Bacillus cereus, Bacillus thuringiensis and Bacillus anthracis extracellular proteomes.

Bacillus cereus, Bacillus thuringiensis and Bacillus anthracis are closely related species that share a similar genetic background but occupy different ecological niches. Virulence plasmids bearing genes coding for toxins, may explain, at least partly, this specialization. We have compared by 2-DE in the early stationary phase of growth the extracellular proteomes of three strains of these species that have lost their virulence plasmids.
