MicroRNA (miRNA) are small non-coding RNA that post-transcriptionally regulate gene expression. In humans, miRNA genes may account for 2 to 3% of the total number of genes. Although the biological functions of most miRNA are unknown, their importance for development, cell proliferation, cell death, and morphogenesis has been demonstrated in several species.(More)
BACKGROUND Cattle are important agriculturally and relevant as a model organism. Previously described genetic and radiation hybrid (RH) maps of the bovine genome have been used to identify genomic regions and genes affecting specific traits. Application of these maps to identify influential genetic polymorphisms will be enhanced by integration with each(More)
BACKGROUND MicroRNAs (miRNAs) are small non-coding RNAs that have been found to play important roles in silencing target genes and that are involved in the regulation of various normal cellular processes. Until now their implication in the mammary gland biology was suggested by few studies mainly focusing on pathological situations allowing the(More)
BACKGROUND Several approaches can be used to determine the order of loci on chromosomes and hence develop maps of the genome. However, all mapping approaches are prone to errors either arising from technical deficiencies or lack of statistical support to distinguish between alternative orders of loci. The accuracy of the genome maps could be improved, in(More)
In this study, we report that the release of IL-1 receptor antagonist (IL-1ra) from IL-4-stimulated neutrophils is markedly enhanced in the presence of IL-10. We also show that up-regulation of IL-1ra release by IL-10 in IL-4-stimulated neutrophils takes place through IL-1ra mRNA stabilization and enhancement of IL-1ra de novo synthesis. Furthermore, we(More)
A high percentage of uveal melanoma patients develop metastatic tumors predominantly in the liver. We studied the molecular profiles derived from gene expression microarrays and comparative genomic hybridization microarrays, to identify genes associated with metastasis in this aggressive cancer. We compared 28 uveal melanomas from patients who developed(More)
On the basis of fine mapping of a quantitative trait loci region of BTA3 for milk fat content, an examination of the comparative map between cattle and human indicates that the annexin 9 protein gene (ANXA9) and the fatty acid transport protein type 3 gene (SLC27A3) are two strong candidate genes. The objective of the present study is to isolate, map and(More)
