Beschreibung: Recent advances in biotechnology have created many public policy and legal issues, one of the most significant of which is the treatment of biotechnological industrial products, particularly under the patent system. Patents represent one of several types of intellectual property; their ownership confers the right to exclude others from benefitting from the tangible products of a proprietary subject matter. Intellectual property law and its protections will play a major role in the rate at which biotechnology develops in the United States. In this article biotechnological intellectual property issues are reviewed in the context of their underlying legal requirements. The implications of other factors, such as international competition, research funding, and gene ownership, are also considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adler, R G -- New York, N.Y. -- Science. 1984 Apr 27;224(4647):357-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6584975" target="_blank"〉PubMed〈/a〉

Heterochronic mutants of the nematode Caenorhabditis elegans (1984)

Publikationsdatum: 1984-10-26

Beschreibung: Mutations in the Caenorhabditis elegans genes lin-14, lin-28, and lin-29 cause heterochronic developmental defects: the timing of specific developmental events in several tissues is altered relative to the timing of events in other tissues. These defects result from temporal transformations in the fates of specific cells, that is, certain cells express fates normally expressed by cells generated at other developmental stages. The identification and characterization of genes that can be mutated to cause heterochrony support the proposal that heterochrony is a mechanism for phylogenetic change and suggest cellular and genetic bases for heterochronic variation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ambros, V -- Horvitz, H R -- GM24663/GM/NIGMS NIH HHS/ -- GM24943/GM/NIGMS NIH HHS/ -- HD00369/HD/NICHD NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1984 Oct 26;226(4673):409-16.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6494891" target="_blank"〉PubMed〈/a〉

Beschreibung: Orally administered Trichinella spiralis muscle larvae were rapidly expelled by rat pups suckling an immune dam. The immunity was delivered in the milk; substantial resistance was conferred on normal rat pups suckled for only 24 hours by a Trichinella-immune foster mother. The pups were protected by oral or systemic administration of specific serum antibodies. When infused into a normal lactating dam, these antibodies accumulated in the serum of her suckling pups.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Appleton, J A -- McGregor, D D -- AI 14490/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 5;226(4670):70-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6474191" target="_blank"〉PubMed〈/a〉

Beschreibung: Crude extracts of rat atria reduced the basal amount of aldosterone released from rat zona glomerulosa cells and partially inhibited aldosterone stimulation by adrenocorticotropic hormone and angiotensin II. The destruction of this activity by trypsin suggests that the active factor is a peptide, possibly atrial natriuretic factor. These data suggest that atrial natriuretic factor affects sodium excretion by the kidneys both directly and through the inhibition of aldosterone production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Atarashi, K -- Mulrow, P J -- Franco-Saenz, R -- Snajdar, R -- Rapp, J -- New York, N.Y. -- Science. 1984 Jun 1;224(4652):992-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6326267" target="_blank"〉PubMed〈/a〉

Stress hormones: their interaction and regulation (1984)

Beschreibung: Stress stimulates several adaptive hormonal responses. Prominent among these responses are the secretion of catecholamines from the adrenal medulla, corticosteroids from the adrenal cortex, and adrenocorticotropin from the anterior pituitary. A number of complex interactions are involved in the regulation of these hormones. Glucocorticoids regulate catecholamine biosynthesis in the adrenal medulla and catecholamines stimulate adrenocorticotropin release from the anterior pituitary. In addition, other hormones, including corticotropin-releasing factor, vasoactive intestinal peptide, and arginine vasopressin stimulate while the corticosteroids and somatostatin inhibit adrenocorticotropin secretion. Together these agents appear to determine the complex physiologic responses to a variety of stressors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Axelrod, J -- Reisine, T D -- New York, N.Y. -- Science. 1984 May 4;224(4648):452-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6143403" target="_blank"〉PubMed〈/a〉

Beschreibung: A novel eukaryotic hybrid gene has been constructed from the 5' sequence of a rat gene and the bacterial neomycin-resistance gene. After transfection into hamster fibroblasts, the neo transcripts can be induced to high levels by the absence of glucose. Furthermore, this hybrid gene can be regulated by temperature when it is introduced into a temperature-sensitive mutant cell line.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Attenello, J W -- Lee, A S -- CA-27607/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Oct 12;226(4671):187-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6484570" target="_blank"〉PubMed〈/a〉

Beschreibung: Activated mature T cells require T-cell growth factor (TCGF) for continuous proliferation. However, many mature T cells infected with human T-cell leukemia-lymphoma virus grow independently of exogenously added TCGF. It is now reported that cells infected with this virus also lack detectable TCGF messenger RNA (less than one copy per cell) and thus do not produce their own growth factor. The results apparently rule out an autostimulation mechanism of growth control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arya, S K -- Wong-Staal, F -- Gallo, R C -- New York, N.Y. -- Science. 1984 Mar 9;223(4640):1086-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6320374" target="_blank"〉PubMed〈/a〉

Beschreibung: Bromodeoxyuridine (BrdUrd) treatment of the prolactin nonproducing subclone of GH cells (rat pituitary tumor cells) induces amplification of a 20-kilobase DNA fragment including all of the prolactin gene coding sequences. This amplified DNA segment, which is flanked by two unamplified regions, thus designates a unit of BrdUrd-induced amplified sequence. Cloned DNA segments, 10.3 kilobases long, from the 5' end of the rat prolactin gene of BrdUrd-responsive and -nonresponsive cells, were ligated to the thymidine kinase gene of herpes simplex virus type 1 (HSV1TK), and the hybrid DNA was transferred to thymidine kinase-deficient mouse fibroblast cells by transfection. The HSV1TK gene and the rat prolactin gene were amplified together in drug-treated transfectants carrying the hybrid DNA HSV1TK gene and rat prolactin gene of BrdUrd-responsive GH cells. These results suggest that the 10.3-kilobase DNA segment at the 5' end of the rat prolactin gene of BrdUrd-responsive GH cells carries the information for drug-induced gene amplification (amplicon) and that another gene, such as the HSV1TK gene, is also amplified when the latter is placed adjacent to this segment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biswas, D K -- Hartigan, J A -- Pichler, M H -- CA28218/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 31;225(4665):941-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089335" target="_blank"〉PubMed〈/a〉
