PURPOSE Tumors of the Ewing family are characterized by chromosomal translocations that yield chimeric transcription factors, such as EWS/FLI1, which regulate the expression of specific genes that contribute to the malignant phenotype. In the present study, we show that cholecystokinin (CCK) is a new target of the EWS/FLI1 oncoprotein and assess its(More)
BACKGROUND Retinoblastoma, a prototype of hereditary cancer, is the most common intraocular tumour in children and potential cause of blindness from therapeutic eye ablation, second tumours in germ line carrier's survivors, and even death when left untreated. The molecular scanning of RB1 in search of germ line mutations lead to the publication of more than(More)
BACKGROUND Epigenetic alterations and loss of heterozygosity are mechanisms of tumor suppressor gene inactivation. A new carcinogenic pathway, targeting the RAS effectors has recently been documented. RASSF1A, on 3p21.3, and NORE1A, on 1q32.1, are among the most important, representative RAS effectors. METHODS We screened the 3p21 locus for the loss of(More)
BACKGROUND RAD54L (OMIM 603615, Locus Link 8438) has been proposed as a candidate oncosupressor in tumours bearing a non-random deletion of 1p32, such as breast or colon carcinomas, lymphomas and meningiomas. In a search for RAD54L mutations in 29 menigiomas with allelic deletions in 1p, the only genetic change observed was a silent C/T transition at(More)
The aim of this study is to establish an estimation of the global genomic alteration in neuroblastic tumors (ganglioneuromas, ganglioneuroblastomas and neuroblastomas) and correlate them with different clinical parameters (age, sex, diagnosis, Shimada index, proliferation index, tumor location, and 1p and v-myc avian myelocitomatosis viral-related (MYCN)(More)
