MicroRNAs (miRNAs) are small endogenous RNAs and are widely regarded as one of the most important regulators of gene expression in both plants and animals. To define the roles of miRNAs in fetal lung development, we profiled the miRNA expression pattern during lung development with a miRNA microarray. We identified 21 miRNAs that showed significant changes in expression during lung development....
Melittin is the main effective component of bee venom and has extensive biological functions; however, serious side effects have restricted its clinical application. Preclinical and clinical studies showed that the main adverse events were allergic reaction and pain at the administration site. To decrease the toxicity, we prepared melittin nano-liposomes by encapsulating melittin with poloxamer...
Triglyceride (TG), a water-insoluble energy-rich lipid, is secreted by the liver as part of very low density lipoproteins (VLDLs) to supply energy to extrahepatic tissues. Overproduction of VLDL is associated with increased risk of cardiovascular heart disease; this has renewed an interest in factors that affect hepatic TG production. The TG production rate is determined by measuring temporal i...
In this study, a gelatin microparticle-containing self-microemulsifying formulation (SMF) was developed using a spray-drying method to enhance the oral delivery of the poorly water-soluble therapeutic dutasteride. The effect of the amount of gelatin and the type and amount of hydrophilic additives, namely, Gelucire(®) 44/14, poloxamer 407, sodium lauryl sulfate, Soluplus(®), Solutol™ HS15, and ...
Metformin pharmacokinetics are highly dependent upon organic cationic transporters. There is evidence of a change in its renal clearance in hyperlipidemic obese patients, and no information on its metabolic fate. To study some of these aspects, the influence of poloxamer 407 (P407)-induced hyperlipidemia on metformin pharmacokinetics was assessed. Control and P407-treated adult male rats were a...
In mucosal tissues, epithelial M cells capture and transport microbes across the barrier to underlying immune cells. Previous studies suggested that high affinity ligands targeting M cells may be used to deliver mucosal vaccines; here, we show that particle composition and dispersion buffer ionic strength can independently influence their uptake in vivo. First, addition of a poloxamer 188 to na...
PURPOSE To evaluate the possible changes in CYP2E1 expression and activity in hyperlipidemia (HL), we evaluated the pharmacokinetics of chlorzoxazone (CZX) as a CYP2E1 probe in rats with HL induced by poloxamer 407 (HL rats). METHODS The pharmacokinetics of CZX and its 6-hydroxy metabolite (OH-CZX) were evaluated after intravenous administration of 20 mg/kg CZX to both control and HL rats. We...
While age-related insulin resistance and hyperinsulinemia are usually considered to be secondary to changes in muscle, the liver also plays a key role in whole-body insulin handling and its role in age-related changes in insulin homeostasis is largely unknown. Here, we show that patent pores called 'fenestrations' are essential for insulin transfer across the liver sinusoidal endothelium and th...
BACKGROUND The surfactant poloxamer 188 (P188) has been shown to improve survival following hemorrhage. This study used P188 as a small volume resuscitation product in a sedated, sexually mature, male miniature swine severe hemorrhage model for potential improvement in rate and time of survival. METHODS Fourteen swine were anesthetized, catheterized for hemorrhage and resuscitation and allowe...
