The biological significance of low molecular weight RNA associated with tumor virus

Creator:: Carnegie, John William
Abstract:: RNA isolated from BAI strain A (Myeloblastosis) Avian Tumor Virus can be fractionated into two fractions on a sucrose density gradient, one of higher molecular weight and one of low molecular weight. The low molecular weight (LMW) virus RNA was found to chromatograph the same as E. coli tRNA on...

Biological activity of avian myeloblastosis virus RNA in cell-free systems for protein synthesis

Creator:: Olson, Kenneth Charles
Abstract:: Avian myeloblastosis virus RNA was fractionated into a high molecular weight RNA and a low molecular weight RNA fraction by sucrose density centrifugation. The larger RNA component had a sedimentation constant of 65S and the low molecular weight RNA about 4S. The low molecular RNA has two biological properties of...

Isolation and characteristics of the DNA from nuclear polyhedrosis virus

Creator:: Carnegie, John William
Abstract:: The genome of the nuclear polyhedrosis virus which infects the larvae of the tussock moth, the lepidopteran, Hemerocampa pseudotsugata, was isolated, identified as deoxyribonucleic acid, and characterized in terms of its physical and biological properties. An isolation procedure for the viral DNA was established which consisted of the following steps:...

Nucleic acid polymerases associated with neoplasms

Creator:: Kiessling, Ann Drue
Abstract:: RNA tumor viruses, such as avian myeloblastosis virus (AMV) and MC29 virus, cause malignant transformation of the cells they infect. Transformed cells are able to continually produce progeny virus particles. Evidence is given that RNA-dependent RNA polymerase is present in virus infected cells. RNA-dependent RNA polymerase isolated from AMV-infected myeloblasts...

Purification of a ribonucleic acid-dependent ribonucleic acid polymerase from leukemic cells

Creator:: Watson, Kenneth Fredrick
Abstract:: There is good evidence that the infection with avian myeloblastosis virus BAI strain A causes myeloblasts to retain their primitive nature. These cells are able to multiply and produce virus at a relatively constant rate. From these observations, a major problem develops in the study of the virus-induced leukemia, that...

The effect of DDT on infectivity of RNA tumor viruses

Creator:: Chan, Teresa Wai-lan
Abstract:: Chicken embryonic cells (CEC) cultured in vitro were able to withstand the toxicity of DDT at concentrations below 10μg/ml culture medium. When the DDT concentration exceeded the toxic level, CEC appeared vacuolated and lost the spindle-like fibroblastic appearance, Gas chromatographic analysis had shown that the uptake of DDT (3μg/ ml'culture...

Chromatin structure : possible regulatory role in gene expression

Creator:: Herman, Timothy Merle
Abstract:: Chromatin DNA sequences intimately associated with the "core" of the basic, repeating chromatin subunit are shown to be relatively resistant to digestion by micrococcal nuclease. Chromatin DNA sequences lying between adjacent chromatin subunits, as well as DNA sequences in regions of chromatin which are free of chromatin subunits, are subject...

Biochemical studies on the mosquitocidal delta endotoxin of Bacillus thuringiensis subsp. israelensis

Creator:: Pollock, Martin L.
Abstract:: The cytolytic properties of the mosquitocidal 25 Kd protein deltaendotoxin of Bacillus thuringiensis subsp. israelensis (Bti) was studied using the human erythrocyte as a target cell. Both a fixedtime and a kinetic hemolytic bioassay were developed in order to screen a variety of treatments for their influence on the toxinerythrocyte...
