    Enhancement of oncogenesis in C3H/10T1/2 mouse embryo cell cultures by saccharin (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-09-22
    Description: Impure and pure samples of saccharin (2 milligrams per milliliter) did not produce oncogenic transformation of C3H/10T1/2, clone 8, mouse embryo fibroblasts. However, after treatment of the cells with a nontransforming initiating dose (0.1 microgram per milliliter) of 3-methylcholanthrene, continuous treatment with either sample of saccharin (100 micrograms per milliliter) led to significant transformation. It is concluded that in this system saccharin is a cocarginogen, probably functioning as a promoting agent that is 1000-fold less active than the tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mondal, S -- Brankow, D W -- Heidelberger, C -- New York, N.Y. -- Science. 1978 Sep 22;201(4361):1141-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/684434" target="_blank"〉PubMed〈/a〉

    Human breast cancer: androgen action mediated by estrogen receptor (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-02-17
    Description: Growth of the human breast cancer cell line MCF-7 is enhanced by androgens, but only at pharmacological concentrations. Although physiological concentrations of androgens translocate the androgen receptor into the nucleus, no mitogenic effects are observed. By contrast, pharmacological androgens translocate not only the androgen receptor but also the estrogen receptor, and at these high doses significantly increase both DNA and estrogen-dependent protein synthesis. We therefore propose that androgens stimulate MCF-7 cell growth not through the androgen receptor but rather through the estrogen receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zava, D T -- McGuire, W L -- New York, N.Y. -- Science. 1978 Feb 17;199(4330):787-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/622569" target="_blank"〉PubMed〈/a〉

    Tumor promoters inhibit morphological differentiation in cultured mouse neuroblastoma cells (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-05-05
    Description: When added to mouse neuroblastoma cultures, the potent tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate (TPA) inhibits spontaneous neurite formation as well as that induced in response to serum deprivation, prostaglandin E1, 5-bromo-2'-deoxyuridine, and papaverine. Other tumor-promoting macrocyclic plant diterpenes also inhibit neurite formation, whereas nonpromoting diterpenes do not. Inhibition by TPA was reversible and was unrelated to toxicity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ishii, D N -- Fibach, E -- Yamasaki, H -- Weinstein, I B -- New York, N.Y. -- Science. 1978 May 5;200(4341):556-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/644318" target="_blank"〉PubMed〈/a〉

    Chick embryonic skin as a rapid organ culture assay for cellular neoplasia (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-03-03
    Description: We used chick embryonic skin (CES) in organ culture to assess the neoplastic potential of a variety of cultured human and nonhuman cell lines. Cells derived from cancer tissues grew in CES and formed tumors in nude mice while cells derived from normal tissues grew in neither system. The CES proved to be more sensitive than the nude mouse when used to assay SV40 transformed human cells; each of four such lines grew in CES while only one of the four lines grew and formed tumors in nude mice. In addition, the patterns of invasion by inoculated cells can be easily studied in the CES. These results suggest that CES in organ culture offers an inexpensive, rapid, and reliable alternative to the nude mouse as a tumorigenicity test.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noguchi, P D -- Johnson, J B -- O'Donnell, R -- Petricciani, J C -- New York, N.Y. -- Science. 1978 Mar 3;199(4332):980-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/203036" target="_blank"〉PubMed〈/a〉

    Immunofluorescent detection of nuclear double-stranded RNA in situ in Vero and mosquito cells (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-06-23
    Description: Double-stranded RNA (dsRNA) was detected in situ by indirect immunofluorescence with antibodies to dsRNA. It was seen in nuclei of Vero and Aedes albopictus cells, but not in BHK cells, KB cells, chick embryo fibroblasts, or HeLa cells. Reactive dsRNA was present in the nucleoplasm, but not in nucleoli or cytoplasm. Extracted RNA from the whole cell contained from 0.08 percent (BHK) to 0.46 percent (HeLa) dsRNA, as estimated by serological methods. This dsRNA, found in molecules having the size distribution of heterogeneous nuclear RNA, did not renature rapidly after denaturation. The quantity of dsRNA in total extracted RNA did not correlate with the presence or absence of nuclear staining in situ.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stollar, B D -- Koo, R -- Stollar, V -- New York, N.Y. -- Science. 1978 Jun 23;200(4348):1381-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26972" target="_blank"〉PubMed〈/a〉
