The Gene Ontology (GO) project (http://www. geneontology.org/) provides structured, controlled vocabularies and classifications that cover several domains of molecular and cellular biology and are freely available for community use in the annotation of genes, gene products and sequences. Many model organism databases and genome annotation groups use the GO… (More)
During development, growth cones can be guided at a distance by diffusible factors, which are attractants and/or repellents. The semaphorins are the largest family of repulsive axon guidance molecules. Secreted semaphorins bind neuropilin receptors and repel sensory, sympathetic, motor, and forebrain axons. We found that in rat embryos, the olfactory… (More)
The Gene Ontology (GO) Consortium (GOC, http://www.geneontology.org) is a community-based bioinformatics resource that classifies gene product function through the use of structured, controlled vocabularies. Over the past year, the GOC has implemented several processes to increase the quantity, quality and specificity of GO annotations. First, the number of… (More)
The semaphorins comprise a family of secreted and membrane bound proteins that influence development of the nervous system as well as non-neural organs. H.SemaIV was originally isolated from a homozygously deleted region involving a subset of small cell lung cancers, a neuroendocrine derived neoplasm. To investigate H.SemaIV expression, specific polyclonal… (More)
Human probes identifying the cellular homologs of the v-ets gene, Hu-ets-1 and Hu-ets-2, and two panels of rodent-human cell hybrids were used to study specific translocations occurring in acute leukemias. The human ets-1 gene was found to translocate from chromosome 11 to 4 in the t(4;11)(q21;23), a translocation characteristic of a subtype of leukemia… (More)
BACKGROUND We attempted to clone candidate genes on 10p 14-15 which may regulate hTERT expression, through exon trapping using 3 BAC clones covering the region. After obtaining 20 exons, we examined the function of RGM249 (RGM: RNA gene for miRNAs) we cloned from primary cultured human hepatocytes and hepatoma cell lines. We confirmed approximately 20 bp… (More)
Source/Description: Human genomic DNA fragments were cloned into m13 and selected by hybridization to poly(dC-dA) poly(dG-dT). Sequencing of the clones provided the information necessary for polymerase chain reaction primer synthesis.
