Name of the Sequence. Ovine lipoprotein lipase cDNA. Genus and Species. Ovis aries. Origin of Clones. Because almost the whole 3′-untranslated region (3′UTR) was found to be lacking from the ovine lipoprotein lipase (LPL) cDNA sequence (1,656 bp including the 5′UTR, the coding sequence, and the first 44 bp of the 3′UTR) published by Edwards et al. (1993), we have undertaken to characterize this...

Abstract Background Breast cancer 2, early onset ( BRCA2 ) is a tumor suppressor gene. The protein encoded by this gene plays an important role in homologous recombination (HR)-mediated DNA repair. Deleterious mutations and downregulation of its expression have been associated with tumorigenesis dogs humans. Thus, regulation level for maintaining homeostasis recombination. Results In study, the...

The 5'untranslated regions (UTR) of the full length mRNA of the HIV-1 proviral clones pNL4.3 and pLAI, harbor an internal ribosomal entry site (IRES). In this study we extend this finding by demonstrating that the mRNA 5'UTRs of natural variants of HIV-1 also exhibit IRES-activity. Cap-independent translational activity was demonstrated using bicistronic mRNAs in HeLa cells and in Xenopus laevi...

In many developmentally and functionally important higher plant plastid genes, expression depends on a specific nuclear-encoded RNA polymerase (NEP). Molecular mechanisms for NEP-mediated gene expression are poorly understood. We have improved a transient expression assay based on biolistics and the dual-luciferase reporter technique, which facilitated investigations into the regulation of plas...

Mutations in the Breast-Cancer-1 (BRCA1) gene are the major cause of familial breast/ovarian cancer. Among familial breast cancer only, 15-20% have been suggested to have a deleterious mutation in BRCA1. A highly sensitive method (REF-SSCP) was applied to screen the open reading frame and the 5'UTRs of BRCA1 for mutations. The patient cohort comprised 61 unrelated moderate to high risk breast c...
