Systems level identification of a matrisome-associated macrophage polarisation state in multi-organ fibrosis.

Tissue fibrosis affects multiple organs and involves a master-regulatory role of macrophages which respond to an initial inflammatory insult common in all forms of fibrosis. The recently unravelled multi-organ heterogeneity of macrophages in healthy and fibrotic human disease suggests that macrophages expressing osteopontin (SPP1) associate with lung and liver fibrosis. However, the conservation of this SPP1 macrophage population across different tissues and its specificity to fibrotic diseases with different etiologies remain unclear.

Expression of angiopoietin 1, 2 and their common receptor Tie2 in human gastric carcinoma: implication for angiogenesis.

Angiogenesis, formation of new microvessels providing oxygen and nutrient supply, is essential for tumor growth. It is dependent on the production of angiogenic growth factors by tumor cells. Angiopoietin 1 (Ang-1) and 2 (Ang-2) and their common receptor, Tie2, are thought to be critical regulators of tumor angiogenesis.

Low dose ethanol potentiates indomethacin induced inhibition of wound re-epithelialization in duodenal monolayers.

Nonsteroidal anti-inflammatory drugs (NSAIDs) induce gastroduodenal mucosal injury and ulceration, and delay ulcer healing. In contrast, the effects of low dose ethanol in induction of gastroduodenal mucosal injury, and the subsequent wound repair remains unclear. The aim of this study was to determine, using an in-vitro duodenal epithelial wound model, whether low clinically relevant doses of ethanol or indomethacin interfere with the wound re-epithelialization of duodenal epithelial monolayers.
