Arguably, almost all research in Drosophila can be considered basic research, yet many of the most essential and fundamental concepts of human genetics were first decoded in the fly. Although the fly genome, which is organized into only four chromosomes, is approximately one-twentieth the size of the human genome, it contains roughly the same number of(More)
Adenosine-to-inosine RNA editing is a highly conserved process that post-transcriptionally modifies mRNA, generating proteomic diversity, particularly within the nervous system of metazoans. Transcripts encoding proteins involved in neurotransmission predominate as targets of such modifications. Previous reports suggest that RNA editing is responsive to(More)
Post-transcriptional modifications such as RNA editing and splicing diversify the proteome while limiting the necessary size of the genome. Although splicing globally rearranges existing information within the transcript, the conserved process of adenosine-to-inosine RNA editing recodes the message through single nucleotide changes, often at very specific(More)
The use of hypnotics in the elderly must be approached with special care in view of possible changes in pharmacokinetic behaviour and drug interactions in older patients. In a randomized, double-blind study in a large geriatric department, midazolam was compared with the barbiturate combination Vesparax with regard to efficacy and safety. The comparison of(More)
The specificity and extent of RNA editing by ADAR enzymes is determined largely by local primary sequence and secondary structural imperfections in duplex RNA. Here we surgically alter conserved cis elements associated with a cluster of ADAR modification sites within the endogenous Drosophila paralytic transcript. In addition to the local requirement for a(More)
The successful use of gene expression microarrays in basic research studies has spawned interest in the use of this technology for clinical trial and population-based studies, but cost, complexity of sample processing and tracking, and limitations of sample throughput have restricted their use for these very large-scale investigations. The Affymetrix(More)
Heterogametic species require chromosome-wide gene regulation to compensate for differences in sex chromosome gene dosage. In Drosophila melanogaster, transcriptional output from the single male X-chromosome is equalized to that of XX females by recruitment of the male-specific lethal (MSL) complex, which increases transcript levels of active genes 2-fold.(More)
The conserved histone locus body (HLB) assembles prior to zygotic gene activation early during development and concentrates factors into a nuclear domain of coordinated histone gene regulation. Although HLBs form specifically at replication-dependent histone loci, the cis and trans factors that target HLB components to histone genes remained unknown. Here(More)
