A subset of gastrointestinal stromal tumors (GISTs) lack gain-of-function mutations in c-KIT and PDGFRalpha. These so-called wild-type (WT) GISTs tend to be less responsive to imatinib-based therapies and have a poor prognosis. We identified amplification of IGF1R in a SNP analysis of GIST and thus studied its potential as a therapeutic target in WT and(More)
Frequency of INherited Disorders database (FINDbase) (http://www.findbase.org) is a relational database, derived from the ETHNOS software, recording frequencies of causative mutations leading to inherited disorders worldwide. Database records include the population and ethnic group, the disorder name and the related gene, accompanied by links to any(More)
UNLABELLED Germline polymorphisms of detoxification genes could influence susceptibility to Multiple Sclerosis (MS). Glutathione-S-transferases (GSTs) and NAD(P)H quinone oxidoreductase 1 (NQO1) are detoxifying enzymes involved in biotransformation of metabolites preventing cells from oxidative damage. In order to evaluate the possible contribution of the(More)
The NQO1 C(609)T germline polymorphism resulting in a lowering of enzyme activity may confer susceptibility to MDS. To assess this association, we performed a case-control study including 330 Greek patients with de novo MDS and 416 healthy donors, using a Real-Time PCR genotyping method. Focusing on cytogenetic aberrations most commonly found in MDS, we(More)
The unbalanced t(1;9) is a rare, recurrent rearrangement in polycythemia vera (PV) resulting in trisomy of both 1q and 9p arms, whereas a balanced t(1;9)(q12;q12), to our knowledge, has never been reported before. We studied two patients with PV and one with idiopathic myelofibrosis bearing an unbalanced t(1;9) and one patient with essential thrombocythemia(More)
A series of cationic liposomes known as cationic phosphonolipids (CPs) were evaluated as vehicles for in vitro gene transfer in K562 erythroleukemia cells and 5637 epithelial carcinoma cells. For each CP and target cell type examined, detailed analyses were performed to determine optimal transfection conditions (lipid/ DNA (+/-) charge ratio, amount of(More)
PURPOSE There has been a recent and dramatic increase in the pace of drug development for colorectal cancer which holds promise to further improve curative therapy. We tested lactandrate, an alkylating ester of D-lactam androsterone, for antineoplastic activity against colon adenocarcinoma in vitro and in vivo. MATERIALS AND METHODS The cytostatic and(More)
