Liver diseases are associated with complex changes in the hemostatic system and elevated levels of the platelet-adhesive protein Von Willebrand factor (VWF) are reported in patients with acute and chronic liver damage. Although elevated levels of VWF are associated with fibrosis in the general population, the role of VWF in acute and chronic liver injury has not been examined in depth in experimental settings. We tested the hypothesis that VWF deficiency inhibits experimental liver injury and fibrosis. Wild-type (WT) and VWF-deficient mice were challenged with carbon tetrachloride (CCl4) and the impact of VWF deficiency on acute liver injury and chronic liver fibrosis was determined...

Granulocyte colony-stimulating factor (G-CSF) is routinely used in the clinic to mobilize hematopoietic stem progenitor cells (HSPC) into the patient's blood for collection and subsequent transplantation. However a significant proportion of patients who have previously received chemotherapy or radiotherapy and requiring autologous HSPC transplantation, cannot mobilize the minimal threshold of mobilized HSPC to achieve rapid and successful hematopoietic reconstitution. Although several alternatives to the G-CSF regime have been tested, few are in use in the clinic...

Recent studies implicate the Cyr61, CTGF, Nov (CCN) matricellular signaling protein family as emerging players in vascular biology, with NOV (alias CCN3) as an important regulator of vascular homeostasis. Herein, we examined the role of CCN3 in the pathogenesis of atherosclerosis. In response to a 15-week high-fat diet feeding, CCN3-deficient mice on the atherosclerosis-prone Apoe(-/-) background developed increased aortic lipid-rich plaques compared to control Apoe(-/-) mice, a result that was observed in the absence of alterations in plasma lipid content...

Nuclear receptors are a family of transcription factors that can be activated by lipophilic ligands. They are fundamental regulators of development, reproduction, and energy metabolism. In bone, nuclear receptors enable bone cells, including osteoblasts, osteoclasts, and osteocytes, to sense their dynamic microenvironment and maintain normal bone development and remodeling. Our views of the molecular mechanisms in this process have advanced greatly in the past decade. Drugs targeting nuclear receptors are widely used in the clinic for treating patients with bone disorders such as osteoporosis by modulating bone formation and resorption rates...

BACKGROUND We investigated the frequency, clinical presentation, risk factors, and outcome after the first deep vein thrombosis (DVT) event. MATERIAL AND METHODS A retrospective study was conducted for patients with DVT between 2008 and 2012 with a 1-year follow-up. Patients were divided into 2 groups: single vs. recurrent DVT (RDVT). RESULTS Of the 6420 patients screened for DVT, 662 (10.3%) had DVT. RDVT constituted 22% of cases. A single event was more frequent in left lower limb DVT (p=0.01), while RDVT cases had more bilateral DVT (p=0...

Elevated blood pressure (BP) and headache have long been linked in the medical literature. Headache associated with arterial hypertension is a main concern in emergency department. It is believed that headache may be a symptom attributed to arterial hypertension only if the BP values are very high or rise quickly. Many studies support the hypothesis that migraine patients have an increased risk of developing hypertension, while hypertensive subjects do not seem to have an increased risk of migraine or other types of headache...

It has been reported that abnormal elevation of homocysteine is quite prevalent in ulcerative colitis (UC) patients. We attempted to explore the relationship of UC with transcobalamin II (TCN2) gene polymorphisms and serum homocysteine, vitamin B12, and folate levels in Chinese patients. TCN2 (rs1801198, rs9606756) genotypes were detected by the improved multiple ligase detection reaction (iMLDR) technique in 527 UC patients and 574 controls. Moreover, 128 UC patients and 138 controls were randomly selected for the measurement of homocysteine, vitamin B12, and folate levels by enzymatic cycling assay or chemiluminescence immunoassay...

EGFL7 is a secreted, angiogenic factor produced by embryonic endothelial cells. To understand its role in placental development, we established a novel Egfl7 knockout mouse. The mutant mice have gross defects in chorioallantoic branching morphogenesis and placental vascular patterning. Microangiography and 3D imaging revealed patchy perfusion of Egfl7(-/-) placentas marked by impeded blood conductance through sites of narrowed vessels. Consistent with poor feto-placental perfusion, Egfl7 knockout resulted in reduced placental weight and fetal growth restriction...

INTRODUCTION: A rapid increase in awareness of androgen deficiency has led to substantial increases in prescribing of testosterone therapy (TTh), with benefits of improvements in mood, libido, bone density, muscle mass, body composition, energy, and cognition. However, TTh can be limited by its side effects, particularly erythrocytosis. This review examines the literature on testosterone-induced erythrocytosis and polycythemia. AIM: To review the available literature on testosterone-induced erythrocytosis, discuss possible mechanisms for pathophysiology, determine the significance of formulation, and elucidate potential thromboembolic risk...

BACKGROUND: It is unclear whether 25-hydroxyvitamin D [25(OH)D] has a protective effect on long-term prognosis of ischemic stroke and whether it is affected by blood glucose levels. We aim to examine the effect of serum vitamin D especially its deficiency on 1-year poor outcome of ischemic stroke patients in total patients and by blood glucose subgroups. METHODS: A total of 3041 ischemic patients from China Antihypertensive Trial in Acute Ischemic Stroke were included...

OBJECTIVES: Deficiency of 25-hydroxyvitamin D (25[OH]D) is associated with increased risk for cardiovascular disease, perhaps mediated through dyslipidemia. Deficient 25(OH)D is cross-sectionally associated with dyslipidemia, but little is known about longitudinal lipid changes. The aim of this study was to determine the relationship of 25(OH)D deficiency to longitudinal lipid changes and risk for incident dyslipidemia. METHODS: This was a longitudinal community-based study of 13 039 participants from the ARIC (Atherosclerosis Risk in Communities) study who had 25(OH)D and lipids measured at baseline (1990-1992) and lipids remeasured in 1993 to 1994 and 1996 to 1998...

AP1 transcription factors are important controllers of gene expression in the epidermis, and altered AP1 factor function can perturb keratinocyte proliferation and differentiation. However, our understanding of how AP1 signaling changes may underlie or exacerbate skin disease is limited. We have shown that inhibiting AP1 factor function in suprabasal adult epidermis leads to reduced filaggrin levels and to a phenotype that resembles the genetic disorder, ichthyosis vulgaris. We now show that inhibiting AP1 factor function during development in embryonic epidermis produces marked phenotypic changes including reduced filaggrin mRNA and protein levels, compromised barrier function, marked ultrastructural change and enhanced dehydration susceptibility that resembles the phenotype observed in the flaky tail mouse, a model for ichthyosis vulgaris...

RIC8A functions as a chaperone and guanine nucleotide exchange factor for a subset of G protein α subunits. Multiple G protein subunits mediate various signalling events that regulate cell adhesion and migration and the involvement of RIC8A in some of these processes has been demonstrated. We have previously shown that the deficiency of RIC8A causes a failure in mouse gastrulation and neurogenesis - major events in embryogenesis that rely on proper association of cells with the extracellular matrix (ECM) and involve active cell migration...

BACKGROUND: Myocardial infarction (MI) is a major disease burden. Wild-type p53-induced phosphatase 1 (Wip1) has been studied extensively in the context of cancer and the regulation of different types of stem cells, but the role of Wip1 in cardiac adaptation to MI is unknown. We investigated the significance of Wip1 in a mouse model of MI. METHODS: The study began in June 2014 and was completed in July 2016. We compared Wip1-knockout (Wip1-KO) mice and wild-type (WT) mice to determine changes in cardiac function and survival in response to MI...

In liver transplant (LT) recipients, the cause of graft dysfunction in pregnancy is often difficult to ascertain. Moreover, a liver biopsy in late pregnancy is often avoided as a consequence of patient and physician factors. Management of graft dysfunction can be difficult in this setting. We report a 30-year-old female LT recipient who developed acutely deranged liver biochemistry during the third trimester of her first pregnancy. At 29 weeks gestation, her liver function test (LFT) became abnormal; AST peaked at 978 IU/L (normal range 10-50), GGT 25 IU/L (normal range 1-55), bilirubin 1...

The adaptor protein TNF receptor associated factor (TRAF) 3 is required for effective TCR signaling and normal T cell effector functions, and associates with the CD3/CD28 complex upon activation. To determine how TRAF3 promotes proximal TCR signaling, we studied TRAF3-deficient mouse and human T cells, which showed a marked reduction in activating phosphorylation of the TCR-associated kinase Lck. The impact of TRAF3 on this very early signaling event led to the hypothesis that TRAF3 restrains one or both of two known inhibitors of Lck, C-terminal Src kinase (Csk) and protein tyrosine phosphatase N22 (PTPN22)...
