MicroRNAs

By | March 28, 2002

Large families of RNA molecules of 21-22 nucleotides, called microRNAs, have been found in a number of species. In an Advanced Online Publication from Nature Genetics, Eric Lai from the University of California at Berkeley, describes a family of microRNAs in Drosophila (Nat Genet 2002, DOI:10.1038/ng865).He found that 11 Drosophila microRNAs are complementary to the K-box motif (cUGUGAUa), Brd box (AGCUUUA) and GY box (uGUCUUCC) motifs present in the 3' untranslated regions (UTRs) of several bas

Tissue transcriptomes

By | March 27, 2002

In the Early Edition of the Proceedings of the National Academy of Sciences, Andrew Su and collaegues describe high-throughput gene-expression analysis of the mouse and human transcriptomes in different tissues (Proc Natl Acad Sci USA 2002, 10.1073/pnas.012025199).Su etal. performed oligonucleotide hybridisation experiments on samples from 46 human and 45 mouse tissues of diverse origin. They found that 6% of genes are ubiquitously expressed, and individual samples express 30-40% of genes; almos

Arabidopsis

By | March 26, 2002

Now that the Arabidopsis thaliana genome has been sequenced, plant biologists are turning their efforts to genome annotation. In a 21 March report on the Sciencexpress website, Motoaki Seki and colleagues from the RIKEN Institute in Japan, describe a large-scale analysis of full-length Arabidopsis cDNA libraries (Sciencexpress 2002 10.1126/science.1071006).Seki et al. isolated over 150,000 RIKEN Arabidopsis Full-Length (RAFL) cDNA clones, sequenced the ends and clustered them into almost 15,000
