Urinary proteome signature of Renal Cysts and Diabetes syndrome in children.

Sci Rep 2019 Feb 18;9(1):2225. Epub 2019 Feb 18.

Mosaiques Diagnostics GmbH, Hannover, Germany.

Renal Cysts and Diabetes Syndrome (RCAD) is an autosomal dominant disorder caused by mutations in the HNF1B gene encoding for the transcriptional factor hepatocyte nuclear factor-1B. RCAD is characterized as a multi-organ disease, with a broad spectrum of symptoms including kidney abnormalities (renal cysts, renal hypodysplasia, single kidney, horseshoe kidneys, hydronephrosis), early-onset diabetes mellitus, abnormal liver function, pancreatic hypoplasia and genital tract malformations. In the present study, using capillary electrophoresis coupled to mass spectrometry (CE-MS), we investigated the urinary proteome of a pediatric cohort of RCAD patients and different controls to identify peptide biomarkers and obtain further insights into the pathophysiology of this disorder.

Activin Receptor-Like Kinase 1 Combined With VEGF-A Affects Migration and Proliferation of Endothelial Cells From Sporadic Human Cerebral AVMs.

Front Cell Neurosci 2018 9;12:525. Epub 2019 Jan 9.

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Heterozygous loss of activin receptor-like kinase 1 (Alk1) can lead to hereditary hemorrhagic telangiectasia (HHT), which is a kind of vascular disease characterized by direct connections between arteries and veins with the lacking of capillaries, and develops into arteriovenous malformations (AVMs) in later stage. However, the changes of Alk1 in human sporadic cerebral AVMs (cAVMs) remain unknown. In the present study, we used endothelial cells (ECs) derived from human cAVMs (cAVM-ECs) specimens, to explore the characteristics of cAVM-ECs and the relationship between Alk1 and human sporadic cAVMs. Read More

STAM-binding protein regulates melanoma metastasis through SLUG stabilization.

Biochem Biophys Res Commun 2018 Dec 16;507(1-4):484-488. Epub 2018 Nov 16.

Division of Pathogenic Biochemistry, Institute of Natural Medicine, University of Toyama, 2630 Sugitani, Toyama, 930-0194, Japan.

STAM-binding protein, STAMBP, is a JAMM-family deubiquitinating enzyme containing the microtubule-interacting/transport domain and STAM-binding domain. Although the biological importance of STAMBP in development has been recognized because the microcephaly-capillary malformation syndrome in human is caused by its somatic mutations, the role of STAMBP in cancer has not yet been determined. In this study, we demonstrate that STAMBP is a key molecule for regulating melanoma migration and invasion, but not survival, by knocking down STAMBP in vitro. Read More

Division of Interventional Radiology, Department of Radiology, University of Texas Southwestern Medical Center, Dallas, TX, USA.

Pulmonary arteriovenous malformation, a condition most commonly associated with hereditary hemorrhagic telangiectasia, is an abnormal communication between the pulmonary artery and pulmonary vein without an intervening capillary communication. Although asymptomatic in ~ 50% individuals, it can present with the dreaded complications of stroke or intracranial abscess in high-risk individuals including pregnant women, if untreated. The mainstay of treatment is now endovascular embolization of the feeding artery which can alleviate the symptoms and prevent these complications. Read More

Blood circulation, facilitating gas exchange and nutrient transportation, is a quintessential feature of life in vertebrates. Any disruption to blood flow, may it be by blockade or traumatic rupture, irrevocably leads to tissue infarction or death. Therefore, it is not surprising that hemostasis and vascular adaptation measures have been evolutionarily selected to mitigate the adverse consequences of altered circulation. Read More

University of Virginia Health System, Department of Radiology and Medical Imaging, 1215 Lee Street, Charlottesville, Virginia, USA; University of Missouri Health System, Department of Radiology, One Hospital Dr, Columbia, Missouri, USA.

Vascular malformations and tumors, also known as "vascular anomalies", comprise an extensive variety of lesions involving all parts of the body. Knowledge of their classification and imaging characteristics is paramount. Whereas hemangiomas are benign vascular tumors, characterized by cellular proliferation and hyperplasia; vascular malformations are not real tumors and characteristically exhibit normal endothelial turnover.

Outcome with topical sirolimus for port wine stain malformations after unsatisfactory results with pulse dye laser treatment alone.

Ann Saudi Med 2018 Sep-Oct;38(5):376-380

Dr. Hebah Mohammadsalam Musalem, Department of Medicine,, Alfaisal University, Riyadh 11551,, Saudi Arabia, T: 966533112656, ORCID:http://orcid.org/0000-0002-2478-9638.

We used a topical formulation of sirolimus for treating port wine stain (PWS). Although pulsed dye laser (PDL) is the current treatment of choice for PWS, fast neovascularization after treatment is a major drawback. With PDL therapy there has been insufficient improvement and frustrating side effects. Read More

Clinical pitfalls in the diagnosis of segmental overgrowth syndromes: a child with the c.2740G > A mutation in PIK3CA gene.

Ital J Pediatr 2018 Sep 19;44(1):110. Epub 2018 Sep 19.

Pediatric Division, Department of Pediatrics, University Hospital of Verona, Verona, Italy.

Background: Overgrowth syndromes are known as a heterogeneous group of conditions characterized by a generalized or segmental, symmetric or asymmetric, overgrowth that may involve several tissues. These disorders, which present a wide range of phenotypic variability, are often caused by mosaic somatic mutations in the genes associated with the PI3K/AKT/mTOR cellular pathway, a signaling cascade that plays a key role in cellular growth. Overgrowth syndromes are frequently misdiagnosed. Read More

Verrucous hemangioma (also known as verrucous venous malformation): A vascular anomaly frequently misdiagnosed as a lymphatic malformation.

Pediatr Dermatol 2018 Nov 14;35(6):e378-e381. Epub 2018 Sep 14.

Department of Pathology, Institut Imagine, APHP, Hôpital Universitaire Necker-Enfants Malades, Université Paris Descartes - Sorbonne Paris Cité, Paris, France.

Verrucous hemangioma or verrucous venous malformation is a superficial venous malformation frequently misdiagnosed as a lymphatic malformation because of its classical hyperkeratotic appearance. Clinical characteristics of VVM were studied in patients with a histologically confirmed VVM, and validated in a prospective study of 18 patients. VVM was made of separated vascular elements with irregular shape, in a linear disposition, with variable thickness and keratosis. Read More

Understanding alveolarization to induce lung regeneration.

Respir Res 2018 08 6;19(1):148. Epub 2018 Aug 6.

Member of the German Lung Research Center (DZL), Department of Lung Development and Remodelling, Max Planck Institute for Heart and Lung Research, Parkstrasse 1, 61231, Bad Nauheim, Germany.

Background: Gas exchange represents the key physiological function of the lung, and is dependent upon proper formation of the delicate alveolar structure. Malformation or destruction of the alveolar gas-exchange regions are key histopathological hallmarks of diseases such as bronchopulmonary dysplasia (BPD), chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis; all of which are characterized by perturbations to the alveolo-capillary barrier structure. Impaired gas-exchange is the primary initial consequence of these perturbations, resulting in severe clinical symptoms, reduced quality of life, and death. Read More

Hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformations: clinical aspects.

Cardiovasc Diagn Ther 2018 Jun;8(3):316-324

Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas, TX, USA.

Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder of blood vessel formation resulting in mucocutaneous telangiectasias and visceral arteriovenous malformations. Nearly half of patients with HHT will have pulmonary arteriovenous malformations (PAVM) that place them at risk for potentially fatal complications that can occur when blood bypasses the pulmonary capillary circulation or as a result of PAVM rupture. Other manifestations of HHT outside the lung may increase the rate and severity of PAVM complications, creating unique clinical challenges. Read More
