Spontaneous pathologic arterial calcifications in childhood can occur in generalized arterial calcification of infancy (GACI) or in pseudoxanthoma elasticum (PXE). GACI is associated with biallelic mutations in ENPP1 in the majority of cases, whereas mutations in ABCC6 are known to cause PXE. However, the genetic basis in subsets of both disease phenotypes(More)
In 5-10% of patients, neurofibromatosis type 1 (NF1) results from microdeletions that encompass the entire NF1 gene and a variable number of flanking genes. Two recurrent microdeletion types are found in most cases, with microdeletion breakpoints located in paralogous regions flanking NF1 (proximal NF1-REP-a and distal NF1-REP-c for the 1.4 Mb type-1(More)
Tau phosphorylation is regulated by a balance between tau kinase and phosphatase activities. Disruption of this equilibrium was suggested to be at the origin of abnormal tau phosphorylation and thereby that might contributes to tau aggregation. Thus, understanding the regulation modes of tau dephosphorylation is of high interest in determining the possible(More)
BACKGROUND Hereditary angioedema is characterized by recurrent attacks of angioedema of the skin, larynx, and gastrointestinal tract. Bradykinin is the key mediator of symptoms. Icatibant is a selective bradykinin B2 receptor antagonist. METHODS In two double-blind, randomized, multicenter trials, we evaluated the effect of icatibant in patients with(More)
Hereditary angioedema (HAE) is characterized clinically by recurrent acute skin swelling, abdominal pain, and potentially life-threatening laryngeal edema. Three forms of HAE have been described. The classic forms, HAE types I and II, occur as a consequence of mutations in the C1-inhibitor gene. In contrast to HAE types I and II, HAE type III has been(More)
BACKGROUND Upper facial port-wine stain (PWS) is a feature of Sturge-Weber syndrome (SWS). Recent studies suggest that the distribution of the PWS corresponds to genetic mosaicism rather than to trigeminal nerve impairment. OBJECTIVES We sought to refine the cutaneous distribution of upper facial PWS at risk for SWS. METHODS This was a prospective(More)
In plants, mechanoperception and transduction of mechanical signals have been studied essentially in Arabidopsis thaliana L. and Lycopersicon esculentum L. plants, i.e., in nonwoody plants. Here, we have described the isolation of both the full-length cDNA and the regulatory region of PtaZFP2, encoding a member of Cys2/His2 zinc finger protein (ZFP) family(More)
In tauopathies such as Alzheimer's disease (AD), the molecular mechanisms of tau protein aggregation into neurofibrillary tangles (NFTs) and their contribution to neurodegeneration remain not understood. It was recently demonstrated that tau, regardless of its aggregation, might represent a key mediator of neurodegeneration. Therefore, reduction of tau(More)
In the present study the right-left brain asymmetry of central dopamine (DA) systems during postnatal brain development is evaluated. DA and dihydroxyphenylacetic acid (DOPAC) levels increased from neonatal to adult life in both the forebrain and mesencephalon. This increase was not similar in the right and left brain sides. From neonatal life to adulthood(More)
BACKGROUND Large congenital melanocytic nevi (LCMN) are defined as congenital melanocytic nevi having a projected adult size exceeding 20 cm in diameter. They occur in 1 in 20,000 to 1 in 500,000 newborns. Therapeutic management of LCMN remains controversial and is often decided according to melanoma risk. OBJECTIVE We sought to synthesize all data(More)
