Abstract:
... 2‐Monoacylglycerol (2‐MAG) is one of the digestion products of dietary lipids. We recently demonstrated that a 2‐MAG, 2‐arachidonoyl glycerol (2‐AG) potently stimulated cholecystokinin (CCK) secretion via cannabinoid receptor 1 (CB1) in a murine CCK‐producing cell line, STC‐1. CCK plays a crucial role in suppressing postprandial gastric emptying. To examine the effect of 2‐AG on gastric emptying, ...

Abstract:
... Plant-based diets are a great source of protease inhibitors (PIs). Two of the most well-known families of PIs are Bowman-Birk inhibitors (BBI) and Kunitz-type inhibitors (KTI). The first group acts mainly on trypsin, chymotrypsin, and elastase; the second is on serine, cysteine, and aspartic proteases. PIs can retard or inhibit the catalytic action of enzymes; therefore, they are considered non-nu ...

Abstract:
... Fine particulate matter (PM₂.₅) poses a significant risk to human health worldwide, by promoting oxidative stress and inflammation; however, the components responsible for these effects have not been fully evaluated. In this study, we investigated the cellular response of a macrophage cell line exposed to PM₂.₅ extracts in vitro. We obtained a dataset of chemical components of PM₂.₅ and determined ...

ALI is extremely harmful and can induce severe disease states, such as hepatitis, liver fibrosis, cirrhosis, or liver cancer, which are similar to CCl₄-induced liver disease states in animals. In recent studies, the pathological changes of hepatocytes and the hepatic ...

Abstract:
... In type 2 diabetes, lipotoxicity damages islet microvascular endothelial cells (IMECs), leading to pancreatic islet β cell dysfunction directly or indirectly. Glucagon-like peptide-1 (GLP-1) and its analogs have beneficial roles in endothelial cells. However, the protective effects of GLP-1 agents on IMECs and their potential mechanism remained obscure. In this study, exposure of MS-1 (a cell line ...

In recent years, the immunoregulatory function of extracellular vesicles (EVs) has been reported; therefore, it is inferred that EVs play a role in immune-mediated hepatitis. In this study, we investigated the immunoregulatory function of EVs in concanavalin A (Con ...
