Protein kinases of the microtubule affinity-regulating kinase (MARK) family were originally discovered because of their ability to phosphorylate tau protein and related microtubule-associated proteins (MAPs), and their role in the establishment of cell polarity in different contexts. Recent papers have indicated that microtubule affinity-regulating kinase 4(More)
PURPOSE Cortical dysplasia (CD) represents a wide range of histopathological abnormalities of the cortical mantle that are frequently associated with drug-resistant epilepsy. Recently, carmustine (1-3-bis-chloroethyl-nitrosurea [BCNU]), given to pregnant rats on embryonic day (E) 15, has been used to develop an experimental model mimicking human CD. The aim(More)
Identification of genetic copy number changes in glial tumors is of importance in the context of improved/refined diagnostic, prognostic procedures and therapeutic decision-making. In order to detect recurrent genomic copy number changes that might play a role in glioma pathogenesis and/or progression, we characterized 25 primary glioma cell lines including(More)
Glioblastomas, the most frequent and malignant glial tumors, are known to be phenotypically heterogeneous. A low fraction of glioblastomas is associated with specific chromosomal losses at 1p and 19q, which are commonly found in oligodendrogliomas and are generally considered to be a primary event in the development of these tumors. Subsequent progression(More)
OBJECTIVE To define distinctive features of nodular heterotopia in specimens derived from drug-resistant patients with epilepsy by evaluating mRNA expression of three different layer-specific markers: Rorbeta, Er81, and Nurr1. METHODS We analyzed the expression profile of these genes, recognized as markers mainly expressed in layer IV for Rorbeta, in(More)
Derangements of cortical development can cause a wide spectrum of malformations, generally termed 'cortical dysplasia' (CD), which are frequently associated with drug-resistant epilepsy and other neurological and mental disorders. 1,3-Bis-chloroethyl-nitrosurea (BCNU)-treated rats represent a model of CD due to the presence of histological alterations(More)
The experimental model of cortical dysplasia (CD) obtained by administering carmustine (1-3-bis-chloroethyl-nitrosurea [BCNU]) in pregnant rat uterus mimics the histopathological abnormalities observed in human CD patients: altered cortical layering, and presence of heterotopia and dysmorphic/heterotopic neurons. To investigate further the cortical layering(More)
It was recently reported that congenital heart disease is significantly more frequent in patients with NF1 microdeletion syndrome than in those with classical NF1. The outcome of congenital heart disease in this subset of patients is likely caused by the haploinsufficiency of gene/s in the deletion interval. Following in silico analysis of the deleted(More)
Alterations of 19q13 are frequently observed in glial neoplasms, suggesting that this region harbors at least one gene involved in gliomagenesis. Following our previous studies on structural 19q chromosome rearrangements in gliomas, we have undertaken a detailed FISH analysis of the breakpoints and identified a 19q13.2 intrachromosomal amplification of the(More)
Kir4.1 is the principal K(+) channel expressed in glial cells. It has been shown that it plays a fundamental role in K(+)-spatial buffering, an astrocyte-specific process where excess extracellular concentration of K(+) ions, generated by synaptic activity, is spatially redistributed to distant sites via astrocytic syncytia. Experimental and clinical(More)
