We determined total Purkinje cell (PC) numbers in cerebella of wild-type (+/+) and heterozygous (rl/+) reeler mice of either sex during early postnatal development; in parallel, we quantified levels of neuroactive steroids in the cerebellum with mass spectrometry. We also quantified reelin mRNA and protein expression with RT-PCR and Western blotting. PC(More)
According to the "extreme-male brain" theory, elevated fetal testosterone levels may partly explain the skewed sex ratio found in Autism Spectrum Disorders (ASD). Correcting this testosterone imbalance by increasing estrogen levels may mitigate the abnormal phenotype. Accordingly, while control heterozygous reeler (rl/+) male mice - a putative model of(More)
The effects of intracerebroventricular administration of neuropeptide Y (NPY), which is believed to play an important role in neuroprotection against excitotoxicity and in the modulation of adult neurogenesis, were evaluated in an animal model of hippocampal neurodegeneration and temporal lobe epilepsy represented by trimethyltin (TMT) intoxication. A(More)
Reelin-deficient mice have been used to investigate the role of this extracellular protein in cortico-striatal plasticity and striatum-related behaviours. Here we show that a repetitive electrical stimulation of the cortico-striatal pathway elicited long-term potentiation (LTP) in homozygous reeler (rl/rl) mice, while causing long-term depression in their(More)
Mitochondria are key organelles for the maintenance of life and death of the cell, and their morphology is controlled by continual and balanced fission and fusion dynamics. A balance between these events is mandatory for normal mitochondrial and neuronal function, and emerging evidence indicates that mitochondria undergo extensive fission at an early stage(More)
Both Reelin and Nerve Growth Factor (NGF) exert crucial roles in retinal development. Retinogenesis is severely impaired in E-reeler mice, a model of Reelin deficiency showing specific Green Fluorescent Protein expression in Rod Bipolar Cells (RBCs). Since no data are available on Reelin and NGF cross-talk, NGF and trkA(NGFR)/ p75(NTR) expression was(More)
RATIONALE Reelin, a large extracellular matrix glycoprotein, is down-regulated in the brain of schizophrenic patients and of heterozygous reeler mice (rl/+). The behavioral phenotype of rl/- mice, however, matches only partially the schizophrenia hallmarks. OBJECTIVES We recently reported (Marrone et al., Eur J Neurosci 24:20062-22070, 2006) that(More)
Multiple sclerosis (MS) is the most common inflammatory demyelinating disorder of the central nervous system (CNS). An approach to improve MS treatment is to identify a rational combination of new medications or existing therapies that impact different aspects of the disease process. Statins are effective in the treatment of MS animal models and are(More)
With the intent of dissecting the molecular complexity of Philadelphia-negative myeloproliferative neoplasms (MPN), we designed a target enrichment panel to explore, using next-generation sequencing (NGS), the mutational status of an extensive list of 2000 cancer-associated genes and microRNAs. The genomic DNA of granulocytes and in vitro-expanded(More)
Cancer stem cells (CSC) were isolated via a non-adherent neurosphere assay from three glioma cell lines: LI, U87, and U373. Using a clonal assay, two clones (D2 and F11) were selected from spheres derived from LI cells and were characterized for the: expression of stem cell markers (CD133, Nestin, Musashi-1 and Sox2); proliferation; differentiation(More)
