Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Glucocorticoids are part of the therapeutic armamentarium of chronic lymphocytic leukemia where it has been suggested that cells with unmutated IGHV genes exhibit higher sensitivity. The mechanisms by which glucorticoids are active in CLL are not well elucidated.
Publication Title

Description
Genetic factors contribute to the development of ischemic stroke but their identity remains largely unknown. We tested the association with ischemic stroke of 210 single nucleotide polymorphisms (SNPs) associated with pathways functionally related to stroke. We observed an association between the rs7956957 SNP in LRP1 and next performed microarrays analysis in healthy individuals to investigate possible associations of LRP genotypes with the expression of other genes.

Description
Spontaneous intracerebral hemorrhage (ICH) represents about 15% of all strokes and is associated with high mortality rates. Our aim was to identify the gene expression changes and biological pathways altered in the brain following ICH.

Description
A genetic study of the PRF1 gene has shown association of several polymorphisms with multiple sclerosis (MS). Haplotype analysis identified risk haplotypes strongly associated with male patients having the primary-progressive form of MS (PPMS). Gene expression microarrays were performed in 10 male PPMS patients carrying the risk (n=6) and protective haplotypes (n=4) in order to identify pathways associated with the risk haplotypes. Pathway analysis revealed overrepresentation of the cell killing gene ontology category among down-regulated genes in patients carrying risk haplotypes compared with patients carrying protective haplotypes.

Description
Permanent synthetic meshes are a prized option to promote soft-tissue support and repair in several surgical procedures. Contrariwise, the risk to develop biomaterial-associated infection (BAI) has not been solved. Intrinsically antibacterial materials, such as those that include metals with antimicrobial activity as part of their composition, are an advanced approach to be further explored for BAI prevention. In this study, a panel of in vitro, ex vivo and in vivo assays was used to compare a novel polypropylene-based surgical mesh modified with silver-containing microparticles with a commercially available similar device normally used for hernia repair. To comprehensively identify specific mechanisms of how the new silver-containing meshes influence the full host-tissue response in the presence and absence of infection, prostheses were screened for cytotoxicity, biological integration and transcriptomic responses, and additional antibiofilm production behaviour. Silver-modified polypropylene meshes exhibited good properties in terms of mechanical and cytotoxic values, as well as a modest prevention of biofilm formation. Moreover, they promoted connective tissue deposition and angiogenesis and, outstandingly, induced immunomodulating effects that may be potentially useful in the clinical context. Overall, the results substantiate the potential use of polypropylene surgical meshes modified with silver-containing microparticles as a means to prevent BAI in soft tissue repair.
