PURPOSE Several studies have suggested that KRAS somatic mutations may predict resistance to cetuximab- and panitumumab-based treatments in metastatic colorectal cancer (CRC) patients. Nevertheless, most experiences were conducted on samples from primaries. The aim of this study was to evaluate the grade of concordance in terms of KRAS status between(More)
The primary end point of the study was the analysis of associations between polymorphisms with putative influence on 5-fluorouracil/irinotecan activity and progression-free survival (PFS) of patients with advanced colorectal cancer treated with first-line FOLFIRI chemotherapy. Peripheral blood samples from 146 prospectively enrolled patients were used for(More)
Photobacteriosis or fish pasteurellosis is a bacterial disease affecting wild and farm fish. Its etiological agent, the gram negative bacterium Photobacterium damselae subsp. piscicida, is responsible for important economic losses in cultured fish worldwide, in particular in Mediterranean countries and Japan. Efforts have been focused on gaining a better(More)
Listeriolysin O (LLO) is a cholesterol-binding sulfhydryl-activated hemolysin encoded by Listeria monocytogenes hlyA gene. After analyzing the nucleotide coding sequence of this gene from the ATCC 9525 L. monocytogenes strain, we cloned it in a pET vector for expression in Escherichia coli. Thanks to the optimization of the induction protocol, we achieved a(More)
PURPOSE To investigate whether prognosis of patients with high-risk gastric cancer may depend on MET copy number gain (CNG) or an activating truncation within a deoxyadenosine tract element (DATE) in the promoter region of the MET ligand HGF. PATIENTS AND METHODS A single-institution cohort of 230 patients with stage II/III gastric cancer was studied.(More)
PURPOSE Regulation of epidermal growth factor receptor (EGFR) signaling pathways may play a relevant role in determining the activity of cetuximab therapy in patients with metastatic colorectal cancer (MCRC). We investigated possible associations between genetic variants and clinical outcomes of MCRC patients treated with cetuximab-irinotecan salvage(More)
We previously reported the structure of the human hexokinase type I (HKI) gene and provided direct evidence of an alternative red blood cell-specific exon 1 located in the 5' flanking region of the gene. Three unique HKI mRNA species have also been described in human spermatogenic cells. These mRNAs contain a testis-specific sequence not present in somatic(More)
This study reports the precise intron/exon boundaries and intron/exon composition of the human hexokinase type I gene. A yeast artificial chromosome containing the hexokinase type I gene was isolated from the yeast artificial chromosome library of the Centre d'Etude du Polymorphisme Humaine. A cosmid sublibrary was created and direct sequencing of the(More)
Polymorphisms in the glucocorticoid receptor (GR) gene have been associated with altered sensitivity to glucocorticoids. We designed a high-resolution melting (HRM) assay to detect, simultaneously, the three most intriguing GR polymorphisms, selected on the bases of clinical relevance and frequencies in caucasian population as described in literature. HRM(More)
Cancer is generally characterized by loss of CG dinucleotides methylation resulting in a global hypomethylation and the consequent genomic instability. The major contribution to the general decreased methylation levels seems to be due to demethylation of heterochromatin repetitive DNA sequences. In human immunodeficiency, centromeric instability and facial(More)
