    The cloning of a family of genes that encode the melanocortin receptors (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-08-28
    Description: Melanocyte-stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH) regulate pigmentation and adrenal cortical function, respectively. These peptides also have a variety of biological activities in other areas, including the brain, the pituitary, and the immune system. A complete understanding of the biological activities of these hormones requires the isolation and characterization of their corresponding receptors. The murine and human MSH receptors (MSH-Rs) and a human ACTH receptor (ACTH-R) were cloned. These receptors define a subfamily of receptors coupled to guanine nucleotide-binding proteins that may include the cannabinoid receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mountjoy, K G -- Robbins, L S -- Mortrud, M T -- Cone, R D -- R01 DK43859-02/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1992 Aug 28;257(5074):1248-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute for Advanced Biomedical Research, Oregon Health Sciences University, Portland 97201.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1325670" target="_blank"〉PubMed〈/a〉

    Tissue-specific expression of functionally rearranged lambda 1 Ig gene through a retrovirus vector (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-05-22
    Description: To explore the potential use of retrovirus vectors for the transfer of genomic DNA sequences into mammalian cells, recombinant retroviral genomes were constructed that encode a functionally rearranged murine lambda 1 immunoglobulin gene. Several of these genomes could be transmitted intact to recipient cells by viral infection, although successful transmission depended both on the orientation of the lambda 1 sequences and on their specific placement within vector sequences. The lambda 1 gene transduced by viral infection was expressed in a cell lineage-specific manner, albeit at lower levels than endogenous lambda 1 gene expression in cells from the B-lymphocyte lineage. Vectors yielding integrated proviruses that lacked viral transcriptional enhancer sequences were used to show that neither viral transcription nor the viral transcriptional sequences themselves had any effect on the tissue specificity of lambda 1 gene expression or the absolute amount of lambda 1 transcription. Vector transcription did, however, dramatically decrease the amount of lambda 1 protein that could be detected in tranduced cells. These results suggest that retrovirus vectors may be useful reagents not only for the expression of complementary DNA sequences but also for studies of tissue-specific transcription in mammalian cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cone, R D -- Reilly, E B -- Eisen, H N -- Mulligan, R C -- CA26712/CA/NCI NIH HHS/ -- CA38497/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1987 May 22;236(4804):954-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3107128" target="_blank"〉PubMed〈/a〉
