Aseptic abscesses (AA) are characterized by deep, sterile, round lesions consisting of neutrophil that do not respond to antibiotics but improve dramatically with corticosteroids. We report the clinical, laboratory, and radiologic characteristics and the associated conditions of 29 patients from the French Register on AA plus 1 patient from the(More)
Prion epizoonoses spread from animals consumed by humans raise the question of which pathways lead to prion neuroinvasion after oral exposure of humans. Here we show that neurons of sympathetic ganglia of patients with variant Creutzfeldt-Jakob disease (vCJD) accumulate the abnormal isoform of the protein prion. This observation shows the involvement of the(More)
BACKGROUND Gliomas constitute the vast majority of primary central nervous system tumors in adults. Glioblastoma multiforme (GBM) is the most aggressive form of these primary brain tumors. There is a need to define diagnostic and prognostic markers that may help to distinguish GBM from non-GBM tumors. The Krüppel-like factor 6 (KLF6) gene has recently(More)
Prostate cancer is the most common cancer among men and the second leading cause of cancer-related deaths in the United States. CpG island methylation causes gene silencing and could be decisive in prostate carcinogenesis and progression. Its role was investigated at multiple gene sites during prostate carcinogenesis. Methylation-specific polymerase chain(More)
Human prion diseases are a heterogeneous group of fatal neurodegenerative disorders, characterized by the deposition of the partially protease-resistant prion protein (PrP(res)), astrocytosis, neuronal loss and spongiform change in the brain. Among inherited forms that represent 15% of patients, different phenotypes have been described depending on the(More)
Radiotherapy is an essential component of glioma standard treatment. Glioblastomas (GBM), however, display an important radioresistance leading to tumor recurrence. To improve patient prognosis, there is a need to radiosensitize GBM cells and to circumvent the mechanisms of resistance caused by interactions between tumor cells and their microenvironment.(More)
Benign prostatic hyperplasia is a nonmalignant enlargement of the prostate that commonly occurs in older men. We show that liver X receptor (Lxr)-α knockout mice (lxrα(-/-)) develop ventral prostate hypertrophy, correlating with an overaccumulation of secreted proteins in prostatic ducts and an alteration of vesicular trafficking in epithelial cells. In the(More)
It is well established that genetic and epigenetic alterations are common events in prostate cancer, which may lead to aberrant expression of critical genes. The importance of epigenetic mechanisms in prostate cancer carcinogenesis is increasingly evident. In this study, the focus will be on histone modifications and the primary objectives are to map(More)
