Estrogen controls key cellular functions of responsive cells including the ability to survive, replicate, communicate and adapt to the extracellular milieu. Changes in the expression of 8400 genes were monitored here by cDNA microarray analysis during the first 32 h of human breast cancer (BC) ZR-75.1 cell stimulation with a mitogenic dose of(More)
The AP2/ERF proteins are plant-specific transcription factors involved in multiple regulatory pathways, from plant organ development to response to various environmental stresses. One of the mechanisms that regulates the AP2-like genes involves the microRNA miR172, which controls their activity at the post-transcriptional level. Extensive studies on(More)
MOTIVATION In eukaryotes, the family of non-coding RNA genes includes a number of genes encoding small nucleolar RNAs (mainly C/D and H/ACA snoRNAs), which act as guides in the maturation or post-transcriptional modifications of target RNA molecules. Since in Drosophila melanogaster (Dm) only few examples of snoRNAs have been identified so far by cDNA(More)
DNA microarray is an innovative technology for obtaining information on gene function. Because it is a high-throughput method, computational tools are essential in data analysis and mining to extract the knowledge from experimental results. Filtering procedures and statistical approaches are frequently combined to identify differentially expressed genes.(More)
DNA microarray technology is a high throughput method for gaining information on gene function. It allows the simultaneous collection of quantitative data about the differential expression of thousands of genes. This large amount of data is analyzed to identify clusters of genes that share common expression characteristics, but the obtained results provide(More)
SUMMARY VIRTLAB is a self-training program based on PBL (Problem-Based-Learning Pathway) built to simulate a molecular biology laboratory. It has been designed to stimulate students in the biological sciences to analyse and solve molecular biology problems using standard laboratory techniques (e.g. restriction enzyme digestions, analytical and preparative(More)
UNLABELLED STRIRED is a toolkit to generate a graphical picture of the distribution of 4- to 6-mer repeats in a set of user-defined nucleic acid sequences. AVAILABILITY The STRIRED package can be downloaded as self-extracting archive (strired.exe) by anonymous FTP from (, in the directory /software/win95/STRIRED. CONTACT(More)
In mammals, the RXFP3 is the cognate receptor of the relaxin-3 peptide (RLN3). In teleosts, many different orthologue genes for RXFP3 are present. In particular, two paralogue genes, rxfp3-2a and rxfp3-2b, likely encode the receptors for the Rln3a peptide. The transcription of these two rxfp3 genes is differentially regulated early during zebrafish(More)
