    Description: Amplification is one of the mechanisms by which cellular oncogenes may be altered in their function, possibly leading to neoplastic transformation. The oncogenes c-myc, c- abl , and c-Ki-ras are amplified in several different human neoplasias. The oncogene c-myb, which is specifically expressed and regulated in hematopoietic cells, was found to be amplified in cell lines ML-1, ML-2, and ML-3, which were separately cultured from cells of a patient with acute myelogenous leukemia (AML). A five- to tenfold amplification was correlated with high levels of expression of normal size c-myb messenger RNA and with chromosomal abnormalities in the region 6q22 -24, where the c-myb locus is normally located. Amplification and cytogenetic abnormalities were detected in DNA's from primary and secondary cultures of ML cells, suggesting that they may have contributed to leukemogenesis. The similar AML cell lines HL-60 and ML's contain different amplified oncogenes: c-myc and c-myb, respectively. Alternative activation of structurally and possibly functionally similar oncogenes may distinguish--at the pathogenetic level--phenotypically similar tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pelicci, P G -- Lanfrancone, L -- Brathwaite, M D -- Wolman, S R -- Dalla-Favera, R -- P30 CA-16087/CA/NCI NIH HHS/ -- RR 05399/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Jun 8;224(4653):1117-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6585957" target="_blank"〉PubMed〈/a〉

    Description: Northern blot analysis of total RNA and polyadenylated RNA isolated from adult rat testes showed that a proopiomelanocortin (POMC)-like messenger RNA molecule is present in these extracts. The testicular POMC messenger RNA is comparable in length to amygdala and midbrain POMC messenger RNA and appears to be at least 200 nucleotides shorter than POMC messenger RNA found in the hypothalamus and anterior and intermediate lobes of the pituitary gland. Hybridization in situ showed that POMC messenger RNA is located in Leydig cells, which are the only testicular cells that contain immunostainable POMC-derived peptides. These results suggest that local synthesis of POMC occurs in the testis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pintar, J E -- Schachter, B S -- Herman, A B -- Durgerian, S -- Krieger, D T -- HD-18110/HD/NICHD NIH HHS/ -- HD-18592/HD/NICHD NIH HHS/ -- NB-02893-15/NB/NB NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):632-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6740329" target="_blank"〉PubMed〈/a〉

    Description: The structure of rat preproatrial natriuretic factor ( preproANF ) was determined by nucleotide sequence analysis of an ANF complementary DNA clone. PreproANF is composed of a hydrophobic leader segment (20 amino acids), a precursor containing one glycosylation site (106 amino acids), and ANF (24 amino acids). Atrial natriuretic factor is located at the carboxyl terminus of the precursor molecule. The human, mouse, and rat genomes each contain a single ANF gene which is highly conserved.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seidman, C E -- Duby, A D -- Choi, E -- Graham, R M -- Haber, E -- Homcy, C -- Smith, J A -- Seidman, J G -- HL-070208/HL/NHLBI NIH HHS/ -- HL-19259/HL/NHLBI NIH HHS/ -- NS-19583/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Jul 20;225(4659):324-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6234658" target="_blank"〉PubMed〈/a〉

    Description: Cellular oncogenes have been implicated in the induction of malignant transformation in some model systems in vitro and may be related to malignancies in vivo in some vertebrate species. This article describes a study of the expression of 15 cellular oncogenes in fresh human tumors from 54 patients, representing 20 different tumor types. More than one cellular oncogene was transcriptionally active in all of the tumors examined. In 14 patients it was possible to study normal and malignant tissue from the same organ. In many of these patients, the transcriptional activity of certain oncogenes was greater in the malignant than the normal tissue. The cellular fes (feline sarcoma) oncogene, not previously known to be transcribed in mammalian tissue, was found to be active in lung and hematopoietic malignancies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slamon, D J -- deKernion, J B -- Verma, I M -- Cline, M J -- AM 18058/AM/NIADDK NIH HHS/ -- CA 15619/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Apr 20;224(4646):256-62.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6538699" target="_blank"〉PubMed〈/a〉

    Description: A novel type D retrovirus was isolated by cocultivation of explants of fibromatous tissue from a rhesus monkey (Macaca mulatta) with immunodeficiency and retroperitoneal fibromatosis. This type D virus, isolated from a macaque with simian acquired immunodeficiency syndrome (SAIDS-D/Washington), is exogenous and is partially related to the Mason-Pfizer and the langur monkey type D viruses. The SAiDS-D virus can be distinguished from all other primate retroviruses by antigenicity and molecular hybridization. Nucleic acid hybridization studies reveal that the origin of the SAIDS-D isolate may reside in Old World monkey (subfamily Colobinae) cellular DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stromberg, K -- Benveniste, R E -- Arthur, L O -- Rabin, H -- Giddens, W E Jr -- Ochs, H D -- Morton, W R -- Tsai, C C -- N01-CO-23909/CO/NCI NIH HHS/ -- N01-CO-23910/CO/NCI NIH HHS/ -- RR00166/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Apr 20;224(4646):289-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6200929" target="_blank"〉PubMed〈/a〉

    Description: Human T-cell leukemia viruses (HTLV) are closely associated with some human T-cell leukemias and lymphomas. A unique 3' region of the HTLV genome is believed to be involved in HTLV-induced cellular transformation, although the function of this region has yet to be determined. A subgenomic messenger RNA transcribed from this region of HTLV has now been characterized. These results provide direct evidence for the expression of a novel gene in HTLV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wachsman, W -- Shimotohno, K -- Clark, S C -- Golde, D W -- Chen, I S -- CA 09297/CA/NCI NIH HHS/ -- CA 30388/CA/NCI NIH HHS/ -- CA 32737/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Oct 12;226(4671):177-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6091270" target="_blank"〉PubMed〈/a〉
