The brush-border membrane (BBM) of enterocytes is responsible for the digestion and absorption of nutrients and ions in the small intestine. To identify the BBM proteins involved in epithelial cell maturation along the crypt-villus axis, enterocytes were sequentially isolated from the villus tip to the crypt of the jejunum from 21-day-old suckling piglets. After preparation of BBM vesicles, we detected 194 proteins in the jejunal epithelial cells by isobaric tags using relative and absolute quantification (iTRAQ) techniques. Of these, 56 BBM proteins were differentially expressed along the crypt-villus axis. During differentiation, the expression of proteins related to digestion and absorption of nutrients was primarily downregulated at the upper, middle villus, or crypt compared to the villus tip, while expression of proteins related to structural and enzyme regulator proteins was largely upregulated. We verified the differences in Na(+)/K(+) -transporting ATPase, galectin-3, and an intestinal-type fatty acid binding protein by western blot or immunochemical analysis. Identification of BBM-associated proteins helps enhance our understanding of digestion and absorption in piglets and other mammals, including humans.

Calcified aortic stenosis is one of the most common causes of heart failure in the elderly. Current guidelines recommend aortic valve replacement in patients with severe disease and evidence of decompensation based on either symptoms or impaired systolic ejection fraction. However, symptoms are often subjective whilst impaired ejection fraction is not a sensitive marker of ventricular decompensation. Interest has surrounded the use of cardiac biochemical markers as objective measures of left ventricular decompensation in aortic stenosis. We will first examine mechanisms of release of biochemical markers associated with myocardial wall stress (BNP/NT-proBNP), myocardial fibrosis (markers of collagen metabolism, galectin-3, soluble ST2) and myocyte death/myocardial ischemia (high-sensitivity cardiac troponins, heart-type fatty acid binding protein, myosin-binding protein C); and discuss future directions of these markers.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by dysregulated autoantibody production and complement activation leading to multi-organ damage. The disease is associated with increased intestinal permeability. In this study, we tested the hypothesis that SLE subjects have increased systemic exposure to bacteria. Since bacteria induce the expression of antimicrobial response factors (ARFs), we measured the levels of a series of clinically relevant ARFs in the plasma of SLE subjects. We found that levels of sCD14, lysozyme, and CXCL16 were significantly elevated in SLE subjects. A strong positive correlation was also observed between sCD14 and SELENA-SLEDAI score. Interestingly, the ratio of EndoCAb IgM:total IgM was significantly decreased in SLE and this ratio was negatively correlated with sCD14 levels. Although, there were no significant differences in the levels of lipopolysaccharide binding protein (LBP) and fatty acid binding protein 2 (FABP2), we observed significant positive correlations between lysozyme levels and sCD14, LBP, and FABP2. Moreover, galectin-3 levels also positively correlate with lysozyme, sCD14, and LBP. Since our SLE cohort comprised 43.33% males, we were able to identify gender-specific changes in the levels of ARFs. Overall, these changes in the levels and relationships between ARFs link microbial exposure and SLE. Approaches to reduce microbial exposure or to improve barrier function may provide therapeutic strategies for SLE patients.
