OBJECTIVE Mitogen-activated protein kinase phosphatase-1 (MKP-1) is one of several oxidized-l-alpha-1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (Ox-PAPC)-induced genes identified in human aortic endothelial cells (HAEC). We previously reported that MKP-1 activity is required for Ox-PAPC-mediated endothelial/monocyte interactions; however, an in vivo role of MKP-1 in atherogenesis ...

Near-infrared fluorescence imaging (NIRFI) and far-red fluorescence imaging (FRFI) were used to investigate effects of depilation-induced skin pigmentation and diet-induced background fluorescence on fluorescent signal amplitude and lymphatic contraction frequency in C57BL6 mice. Far-red fluorescent signal amplitude, but not frequency, was affected by diet-induced fluorescence, which was remove...

Synthetic cannabinoids can affect the immune system and cause some changes in response. The response to Hepatit B vaccine is complex. Studies on hepatitis antibody JWH-018 are extremely limited. main aim of this study was investigate effect anti-HBs Ag before or after Hepatitis vaccination. performed C57BL6 mice (n=25). Mice were divided into 3 groups. Control Group; it immunized Engerix at tim...

The ectopic deposition of fat in liver and muscle during obesity is well established, however surprisingly little is known about the intestine. We used the ob/ob mouse and C57BL6/J mice fed a high fat (HF) diet to examine the effects of obesity and the effects of HF feeding, respectively, on intestinal mucosal triacylglycerol (TG) accumulation. Male C57BL6/J (wild-type, WT) mice were fed low fa...

Angiotensin II type-1 receptor blockers are widely used with the expectation of prevention of stroke, potential effects to ameliorate of type-2 diabetes, which seems to be closely associated with the impairment of cognitive function in humans. Recently, we have reported that an angiotensin II type-1 receptor blocker prevented cognitive impairment in mice after focal cerebral ischemia, at least ...

Mice, similarly to some other rodent species, communicate with specialized sounds in the ultrasonic range called ultrasonic vocalizations (USV). Evaluation of this behavioral activity enables estimation of the social interactions in animal models of autistic spectrum disorders (ASD). Because transgenic mouse models are generated, in most cases, on the mixed 129SV/C57BL6 genetic background, we w...

Abstract Malaria is considered the deadliest disease in human history, killing hundreds of thousands annually. A hallmark severe malaria breakdown blood-organ barriers, such as lungs and brain, but precise mechanism how this occurs remains unknown. We determined that, unlike wildtype mice (C57BL6), with platelet alpha-granule deficiencies (Nbeal2−/−) did not die malaria-associated acute respira...

PURPOSE To investigate cardiomyopathy in offspring in a mouse model of pregestational type 1 diabetic pregnancy. METHODS Pregestational diabetes was induced with STZ administration in female C57BL6/J mice that were subsequently mated with healthy C57BL6/J males. Offspring were sacrificed at embryonic day 18.5 and 6-week adolescent and 12-week adult stages. The size and number of cardiomyocyte...

Rationale: Angiotensin-converting enzyme (ACE)2 opposes the actions of angiotensin (Ang) II by degrading it to Ang 1-7. Objective: Given the important role of Ang II/Ang 1-7 in atherogenesis, we investigated the impact of ACE2 deficiency on the development of atherosclerosis. Methods and Results: C57Bl6, Ace2 knockout (KO), apolipoprotein E (ApoE) KO and ApoE/Ace2 double KO mice were followed u...
