The Wilms' tumor suppressor gene (wt1) product regulates Dax-1 gene expression during gonadal differentiation.

1999

Gonadal differentiation is dependent upon a molecular cascade responsible for ovarian or testicular development from the bipotential gonadal ridge. Genetic analysis has implicated a number of gene products essential for this process, which include Sry, WT1, SF-1, and DAX-1. We have sought to better define the role of WT1 in this process by identifying downstream targets of WT1 during normal gonadal development. We have noticed that in the developing murine gonadal ridge, wt1 expression precedes expression of Dax-1, a nuclear receptor gene. We document here that the spatial distribution profiles of both proteins in the developing gonad overlap. We also demonstrate that WT1 can activate the D…

CC chemokine receptor 5Δ32 polymorphism-a risk factor for ischemic-type biliary lesions following orthotopic liver transplantation

2004

Ischemic-type biliary lesions are a major complication following orthotopic liver transplantation. They occur in up to 26% of liver transplant recipients. Among other factors, unknown immunologic factors have always been assumed to be partly responsible for these lesions. CC-chemokines and their receptors play a key role in postoperative immunomodulation after liver transplantation. The non-function CC-chemokine receptor 5Δ32 polymorphism (CCR5Δ32) has been shown to lead to a lower rate of acute rejection after kidney transplantation; in liver transplantation the role of CCR5Δ32 is unclear. We investigated the influence of the CCR5Δ32 after liver transplantation with special regard to ische…

Tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors predominate as first-line therapy options for renal cell carcinoma. When first-line TKI therapy fails due to resistance development, an optimal second-line therapy has not yet been established. The present investigation is directed towards comparing the anti-angiogenic properties of the TKIs, sorafenib and axitinib on human endothelial cells (HUVECs) with acquired resistance towards the TKI sunitinib. HUVECs were driven to resistance by continuously exposing them to sunitinib for six weeks. They were then switched to a 24 h or further six weeks treatment with sorafenib or axitinib. HUVEC growth, as well as angiogenesis (tube…

Urinary bladder enlargement across nine rodent models of diabetes: correlations with glucose and insulin levels

2021

AbstractThe urinary bladder is markedly enlarged in the type 1 diabetes mellitus model of streptozotocin (STZ)-injected rats, but much less data exist for models of type 2 diabetes (T2DM). Diabetic polyuria has been proposed to explain bladder enlargement. We have collected data on bladder weight and blood glucose from 16 studies representing 9 distinct rodent diabetes (7 T2DM) and obesity models; some included arms with diets and/or pharmacological treatments. Data were analyzed for bladder enlargement and for correlations between bladder weight on the one and glucose levels on the other hand. Our data confirm major bladder enlargements in STZ rats, minor if any enlargement in fructose-fed…

Human Papillomavirus vaccination for the prevention of cervical and other related cancers

2011

Academic research described in the late 1980’s the causal association between human papillomavirus (HPV) and cervical cancer, later expanded to significant fractions of all other genital tract cancers in both genders as well as a proportion of the cancers of the oral cavity and oropharynx. Prophylactic phase III HPV vaccine trials have shown complete type specific vaccine efficacy against two HPV types, namely HPV 16 and 18, that together account for over 70% of cervical cancer worldwide. HPV vaccines have proven in trials to have an excellent safety record. Most developed populations have introduced HPV vaccines as part of their routine vaccination schemes and introduction into developing …

von Hippel-Lindau Protein-Mediated Repression of Tumor Necrosis Factor Alpha Translation Revealed through Use of cDNA Arrays

2003

Based on evidence that the von Hippel-Lindau (VHL) tumor suppressor protein is associated with polysomes and interacts with translation regulatory factors, we set out to investigate the potential influence of pVHL on protein translation. To this end, renal cell carcinoma (RCC) cells that either lacked pVHL or expressed pVHL through stable transfection were used to prepare RNA from cytosolic (unbound) and polysome-bound fractions. Hybridization of cDNA arrays using RNA from each fraction revealed a subset of transcripts whose abundance in polysomes decreased when pVHL function was restored. The tumor necrosis factor alpha (TNF-alpha) mRNA was identified as one of the transcripts that prefere…

Ácido hialurónico como tratamiento en úlcera neuropática: a propósito de un caso

2016

The prevalence of diabetic polyneuropathy in Spain is 22% increasing with age, standing at less than 5% in patients between 15 and 19 years and reaching 29.8% in those aged 70 to 74 years age. Infection is an important complication in Diabetic Foot, frequently associated with minor amputation and even lower extremity amputation. The study presents a clinical case of a 68-year-old man who consulted for a diabetic foot ulcer in the metatarseal area of the right foot, diagnosed two years ago and without healing success. An exploration protocol of the diabetic food was made. Afterwards, a surgical debridement was done and a cure procedure with pure hyaluronic acid, a bandage and foot unloading …

Trans-Abdominal Ultrasound Guided ERC in a Pregnant Woman With Bile Duct Stones

2014

Background: The change in lithogenicity of bile, increased stasis of bile and decreased gall bladder emptying are the possible reasons for an increased risk of gall stones during pregnancy. However, biliary interventions during pregnancy are associated with risks to both the pregnancy and developing fetus. ERC under fluoroscopic control as gold standard is associated with higher risk of premature labor and teratogenity. Methods and patient: We performed transabdominal ultra-sound guided ERC in one patient in the second trimenon with gall stones. While the hilus area is observed by ultrasound, the papilla is carefully cannulated with a guidewire. A contrast agent is applied in the common bil…

Uncommon evolutions and complications of common benign liver lesions

2018

International audience; Frequently encountered on abdominal imaging studies, the majority of common benign liver lesions are asymptomatic, confidently diagnosed by imaging, and do not require further workup, follow-up, or treatment. The increasing use of multimodality liver imaging, has allowed the recognition of uncommon evolutions of common benign liver lesions such as size changes, fibrotic regression, and content and vascularization changes, and their complications such as rupture, hemorrhage, thrombosis, extrinsic compression, and malignancy. The purpose of this pictorial review is to describe and illustrate the incidence and diagnostic features of these uncommon evolutions and complic…

Lingual mucosal graft urethroplasty 12 years later: Systematic review and meta-analysis

2019

Objective: To evaluate the functional results and complications of the lingual mucosal graft (LMG) urethroplasty and to sum up the current state of the art of this surgical technique. Methods: A systematic search of PubMed and Scopus electronic databases was performed, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies involving male patients treated with LMG urethroplasty for urethral stricture were included. Complete protocol is available at http://www.crd.york.ac.uk/PROSPERO/display_record.php?ID=CRD42017080121. A meta-analysis comparing functional and long-term oral complication outcomes of LMG and buccal mucosal graft (BMG) w…
