Gut fuel utilisation has several unique features. Arterial and luminal fuels provide nutrition for the enterocyte, the former being of more importance. This factor, and the heterogeneity of cell types within the gut makes it difficult to define its fuel utilisation. Metabolic control logic suggests that modulation of the maximal activity of any pathway resides in those enzymes that operate in v...

Vitamin A deficiency is a public health problem in most developing countries, especially in children and pregnant women. It is thus a priority in health policy to improve preformed vitamin A and/or provitamin A carotenoid status in these individuals. A more accurate understanding of the molecular mechanisms of intestinal vitamin A absorption is a key step in this direction. It was long thought ...

BACKGROUND Glutamine is routinely added to most cell cultures. Glutamine has been found to be the preferential nutrient to the rapidly replicating intestinal mucosa, but whether this is a metabolic effect or due to other properties of this amino acid is not determined. To study the importance of glutamine on the growth of two enterocyte-like cell lines, the effects of depriving the media or sup...

Treatment of rheumatoid arthritis (RA) with infliximab (Remicade) has been associated with the induction of antinuclear autoantibodies (ANA) and anti-double-stranded DNA (anti-dsDNA) autoantibodies. In the present study we investigated the humoral immune response induced by infliximab against organ-specific or non-organ-specific antigens not only in RA patients but also in patients with ankylos...

Breast cancer (BC) is the most frequent malignant neoplasia and leading cause of mortality for women. A timely diagnosis BC crucial to ensure best chances survival. Among various screening tools BC, antibodies directed towards self-antigens or tumor-associated antigens (autoantibodies) have emerged as an alternative image-based modalities. However, little attention has been paid global diversit...

We describe an implemented model of glucose absorption in the enterocyte, as previously published by Afshar et al. (2019), The used mechanistic descriptions all responsible transporters and was built CellML framework. It validated against experimental data a modular structure which allows each individual transporter to be edited independently from other transport protein models. composite then ...

Systemic lupus erythematosus (SLE) patients with discoid lupus erythematosus (DLE) were reported to have milder disease. To test this observation, we used sandwich arrays containing 98 autoantigens to compare autoantibody profiles of SLE subjects without DLE (DLE-SLE+) (N=9), SLE subjects with DLE (DLE+SLE+) (N=10), DLE subjects without SLE (DLE+SLE-) (N=11), and healthy controls (N=11). We val...

Esophageal squamous cell carcinoma (ESCC), one of the most common malignancies worldwide, is a highly aggressive and homogeneous entity occurring in esophageal squamous epithelium, and a reliable noninvasive test for early detection is needed. A recent study showed that serum autoantibodies against Ezrin could be detected in patients with pancreatic cancer. Here, we assessed whether autoantibod...
