TranscriptomicsHey3Met2 human ovarian cancer cells overexpressing wild type or catalytically-dead mutant RNASET2
Hey3Met2 cells were stably transfected with plasmids encoding either wild-type RNASET2 or a catalytically dead form (whose cDNA has been previously mutagenized in the two CAS catalytic sites) or with the empty vector as a control. The control of ovarian tumorigenesis by RNASET2 occurs through modifi...

TranscriptomicsRNASET2-silenced and control OVCAR3 cell clones injected into nude mice.
To investigate the molecular pathways underlying RNASET2-mediated tumor suppression in vivo, we investigated the gene expression profile of tumor samples obtained from control and RNASET2-silenced OVCAR3 xenografts, respectively. In order to evaluate the contribution of human cancer cells and the...

TranscriptomicsSILENCING OF PNPLA6, THE NEUROPATHY TARGET ESTERASE (NTE) CODIFYING GENE, ALTERS HUMAN NEURODIFFERENTIATION IN VITRO
Neuropathy Target Esterase (NTE) is a protein involved in the development of a polyneuropathy caused by exposure to certain organophosphorus compounds. In vivo and in vitro studies have also associated NTE with embryonic development since NTE null mice embryos are non-viable, and silencing the NTE-c...

TranscriptomicsUnderstanding toxicity pathways of gold nanoparticles: RNA expression study on Caco-2 human colon carcinoma cells
A safer design and higher eficacy of nano-gold therapeutic formulations requires examination of cellular responses to gold nanoparticles (AuNPs). In this work we compared cellular uptake, cytotoxicity and RNA expression patterns induced in Caco-2 cells of citrate-stabilized Au NP of two different si...

TranscriptomicsWhole genome analysis regulation in HepG2 cells exposed to cadmium
Cadmium (Cd) is a metal present in working and living environments known to be toxic and carcinogenic, but its mechanism of action remains still unclear. We investigated the gene expression modulation in human hepatoma cell line HepG2 after exposure to 2 M-BM-5m and 10 M-BM-5m cadmium using Agilent...

TranscriptomicsGenome-wide analysis of mouse macrophages stimulated with IL-4 (bone marrow macrophages) (Affymetrix)
Analysis of alternative activation of macrophages at gene expression level. The study forms part of a wider study where we compare the effects of IL-4 in different human and mouse macrophages. Our results support the notion that in vitro culture conditions greatly affect the macrophage response to I...

TranscriptomicsMicroRNA profiling of human chronic lymphocytic leukemia samples to identify whether microRNA profiles are prognostic indicators
MicroRNA expression profiles can distinguish normal B cells from malignant B cells in chronic lymphocytic leukemia (CLL). We investigated whether microRNA profiles are associated with known prognostic factors in CLL. We evaluated the microRNA expression profiles of 94 samples of CLL cells for which ...

MicroRNA expression profiles can distinguish normal B cells from malignant B cells in chronic lymphocytic leukemia (CLL). We investigated whether microRNA profiles are associated with known prognostic factors in CLL. We evaluated the microRNa expression profiles of 94 samples of CLL cells for which ...

GenomicsHigh density copy number analysis and whole exome sequencing of chronic lymphocytic leukemia

The pathogenesis of chronic lymphocytic leukemia (CLL), the most common leukemia in adults, is still largely unknown since the full spectrum of genetic lesions that are present in the CLL genome, and therefore the number and identity of dysregulated cellular pathways, have not been iden...

TranscriptomicsGenomic and phenotypic alterations of the neuronal-like cells derived from the human embryonal carcinoma stem cells (NT2) caused by exposure to the organophosphorus compounds paraoxon and mipafox
hNT2 under neurodifferentiation were exposed during 4 days to 1 µM of the non-neuropathic organophosphorus compound paraoxon and 5 µM of the neuropathic organophosphorus compound and afterwards transcriptomics were analysed and compared regarding control non-exposed cells Exposure to paraoxon caus...
