Protease-activated receptor 2 drives migration in a colon cancer cell line but not in non-cancerous human epithelial cells
Am J Physiol Gastrointest Liver Physiol. 2024 Mar 5. doi: 10.1152/ajpgi.00284.2023. Online ahead of print.ABSTRACTThe inflamed mucosa contains a complex assortment of proteases which may participate in wound healing or in the development of inflammation-associated colon cancer. We sought to determine the role of protease-activated receptor 2 (PAR2) in epithelial wound healing in both untransformed and transformed colonic epithelial cells. Monolayers of primary epithelial cells derived from organoids cultivated from patient colonic biopsies, and of the T84 colon cancer cell line, were grown to confluence, wounded in the pre...

Hepatic LGR4 aggravates cholestasis-induced liver injury in mice
Am J Physiol Gastrointest Liver Physiol. 2024 Mar 5. doi: 10.1152/ajpgi.00127.2023. Online ahead of print.ABSTRACTCurrent therapy for hepatic injury induced by accumulation of bile acid is limited. Leucine-rich repeat G-protein-coupled receptor 4 (LGR4), also known as GPR48, is critical for cytoprotection and cell proliferation. Here, we reported a novel function for the LGR4 in cholestatic liver injury. In the bile duct ligation (BDL) induced liver injury model, hepatic LGR4 expression was significantly down-regulated. Deficiency of LGR4 in hepatocytes (Lgr4LKO) notably decreased BDL-induced liver injury measured by hepat...

The Effects of Corticotropin-Releasing Hormone on Gastric Electrical Activity and Sensorimotor Function in Healthy Volunteers: A Double-blinded Crossover Study
Am J Physiol Gastrointest Liver Physiol. 2024 Feb 20. doi: 10.1152/ajpgi.00298.2023. Online ahead of print.ABSTRACTBiopsychosocial factors are associated with disorders of gut brain interaction and exacerbate gastrointestinal symptoms. The mechanisms underlying pathophysiological alterations of stress remain unclear. Corticotropin-releasing hormone (CRH) is a central regulator of the hormonal stress response and has diverse impact on different organ systems. The aim of the present study was to investigate the effects of peripheral CRH infusion on meal-related gastrointestinal symptoms, gastric electrical activity and gastr...

Lipidomic signatures discriminate subtle hepatic changes in the progression of porcine non-alcoholic steatohepatitis
Am J Physiol Gastrointest Liver Physiol. 2024 Feb 20. doi: 10.1152/ajpgi.00264.2023. Online ahead of print.ABSTRACTRecently, the development of non-alcoholic steatohepatitis (NASH) in common strains of pigs has been achieved using a diet high in saturated fat, fructose, cholesterol and cholate and deficient in choline and methionine. The aim of the present work was to characterize the hepatic and plasma lipidomic changes that accompany the progression of NASH and its reversal by switching pigs back to a chow diet. One month of this extreme steatotic diet was sufficient to induce porcine NASH. The lipidomic platform using l...
