    Delocalization of Vg1 mRNA from the vegetal cortex in Xenopus oocytes after destruction of Xlsirt RNA (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-08-19
    Description: The Xlsirts are a family of transcribed repeat sequence genes that do not code for protein. Xlsirt RNAs become localized to the vegetal cortex of Xenopus oocytes early in oogenesis, before the localization of the messenger RNA Vg1, which encodes a transforming growth factor-beta-like molecule involved in mesoderm formation, and coincident with the localization of Xcat2 transcripts, which encode a nanos-like molecule. Destruction of the localized Xlsirts by injection of antisense oligodeoxynucleotides into stage 4 oocytes resulted in the release of Vg1 transcripts but not Xcat2 transcripts from the vegetal cortex. Xlsirt RNAs, which may be a structural component of the vegetal cortex, are a crucial part of a genetic pathway necessary for the proper localization of Vg1 that leads to subsequent normal pattern formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kloc, M -- Etkin, L D -- New York, N.Y. -- Science. 1994 Aug 19;265(5175):1101-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas, M.D. Anderson Cancer Center, Houston 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7520603" target="_blank"〉PubMed〈/a〉

    Translocation of repetitive RNA sequences with the germ plasm in Xenopus oocytes (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-12-10
    Description: Xlsirts are a family of interspersed repeat RNAs from Xenopus laevis that contain from 3 to 13 repeat units (each 79 to 81 nucleotides long) flanked by unique sequences. They are homologous to the mammalian Xist gene that is involved in X chromosome inactivation. Xlsirt RNA appears first in the mitochondrial cloud (Balbiani body) in stage 2 oocytes and is then translocated as island-like structures to the vegetal cortex at early stage 3 coincident with the localization of the germ plasm. Exogenous Xlsirt RNA injected into oocytes translocates to the location of the endogenous RNA at that particular stage. The Xlsirt RNA repeat sequences are required for translocation and can cause the translocation of heterologous unique RNAs to the vegetal cortex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kloc, M -- Spohr, G -- Etkin, L D -- New York, N.Y. -- Science. 1993 Dec 10;262(5140):1712-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas, M.D. Anderson Cancer Center, Houston 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7505061" target="_blank"〉PubMed〈/a〉

    Activation of dormant genes in specialized cells (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-06-01
    Description: In several experimental systems the genomic capacity in specialized cells can be assessed by examining the activation of dormant genes. Since some of these specialized cells can be induced to change cell phenotype, all cell specializations do not necessarily involve irreversible genetic changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiBerardino, M A -- Hoffner, N J -- Etkin, L D -- GM 23635/GM/NIGMS NIH HHS/ -- GM 31479/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jun 1;224(4652):946-52.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6719127" target="_blank"〉PubMed〈/a〉

    Transmission of integrated sea urchin histone genes by nuclear transplantation in Xenopus laevis (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-07-01
    Description: Sea urchin histone genes contained in a recombinant plasmid pSp102 were microinjected into the cytoplasm of fertilized eggs of Xenopus laevis. By the late blastula stage, plasmid DNA sequences were detected comigrating with the high molecular weight cellular DNA (greater than 48 kilobases). Analysis of the DNA from injected embryos digested with various restriction endonuclease demonstrated that the injected DNA was integrated into the frog genome. Clones of embryos containing the pSp102 DNA sequences were produced by means of nuclear transplantation. Individuals of the same clone contain the pSp102 sequences integrated into similar chromosomal locations. These sites vary between different clones.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Etkin, L D -- Roberts, M -- GM31479-01/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1983 Jul 1;221(4605):67-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857265" target="_blank"〉PubMed〈/a〉
