-Di(2-ethylhexyl) phthalate (DEHP), a typical endocrine-disrupting chemical (EDC), is widely used as plasticizer. DEHP exposure in humans virtually ubiquitous, and those undergoing certain medical procedures can be especially high. In this study, we investigated whether developmental disrupted glucose homeostasis the rat was associated with early impairment endocrine pancreas. Pregnant Wistar rats were administered (1.25 6.25 mg·kg(-1)·day(-1)) or corn oil throughout gestation lactation by...

Carotenoid content is a primary determinant of wheat nutritional value and affects its end-use quality. Wheat grains contain very low carotenoid levels trace amounts provitamin A content. In order to enrich the in grains, bacterial phytoene synthase gene (CrtB) carotene desaturase (CrtI) were transformed into common cultivar Bobwhite. Expression CrtB or CrtI alone slightly increased transgenic wheat, while co-expression both genes resulted darker red/yellow grain phenotype, accompanied by...

Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) related imbalance, Tau-hyperphosphorylation, and neuroinflammation, in which Aβ neuroinflammation can induce brain insulin resistance (IR). Gut microbiome disorder correlated with inflammation AD. As of yet, there are no effective treatments clinically. Thus, it focused on the potential benefit quercetin-3-O-glucuronide (Q3G), a pharmacologically active flavonol glucuronide, AD treatment regulating IR gut microbiome.

Increasing the provitamin A content in staple crops via carotenoid metabolic engineering is one way to address vitamin deficiency. In this work a combination of methods was applied specifically increase β-carotene wheat by engineering. Endosperm-specific silencing hydroxylase gene (TaHYD) increased 10.5-fold 1.76 μg g–1 endosperm. Overexpression CrtB introduced an additional flux into wheat, accompanied 14.6-fold 2.45 g–1. When "push strategy" (overexpressing CrtB) and "block (silencing...

Abstract Inhibition of immunocyte infiltration and activation has been suggested to effectively ameliorate nonalcoholic steatohepatitis (NASH). Paired immunoglobulin-like receptor B (PirB) its human ortholog receptor, leukocyte (LILRB2), are immune-inhibitory receptors. However, their role in NASH pathogenesis is still unclear. Here, we demonstrate that PirB/LILRB2 regulates the migration macrophages during by binding with ligand angiopoietin-like protein 8 (ANGPTL8). Hepatocyte-specific...

Liraglutide, a modified form of glucagon-like peptide-1 (GLP-1), has been found to improve beta cell function in type 2 diabetes (T2DM). However, the effect liraglutide on under lipotoxic stress and underlying molecular mechanisms remain unclear. In present study, we investigated role PI3K/Akt/FoxO1 signaling liraglutide-involved protection high free fatty acids (FFAs) condition. The apoptosis, proliferation, insulin secretion capability MIN6 cells islets from C57BL/6J mice were evaluated...
