Attempts to localize the replicative form of polyoma virus DNA in mouse embryo cells
… primarily in the nucleus of Py-infected mouse embryo cells. Very little Py I or II* is found in the nucleolus or in the cytoplasm. These two forms of Py DNA are located in the same sub-nuclear fraction. At least half of each is not in association with the nuclear membrane. Possible locations …

Induction of Apoptosis and Necrosis By Infectious Pancreatic Necrosis Virus in Chinook Salmon Embryo Cells
… the induction of apoptosis or necrosis in the cells they infect. Infectious Pancreatic Necrosis Virus (IPNV) is a birnavirus that has been shown to cause severe necrosis in pancreatic, intestinal epithelial, kidney, and liver tissues in infected salmonid fish, but no research indicates the …

Techniques of RNA Isolation and Characterization in Infectious Pancreatic Necrosis Virus-Infected Chinook Salmon Embryo Cells
Infectious pancreatic necrosis virus (IPNV) causes the most lethal disease in young salmonid fishes with mortality rates of equal or higher than ninety-five percent. The survival of the adult fish has been the main cause of this virus's proliferation around the world, making it the most …

Potassium and Sodium Movements Related to Growth State and Malignant Transformation in Cultured Chicken Embryo Cells
… virus-transformed (RSV-transformed) chicken embryo fibroblasts and following serum stimulation of quiescent, density-inhibited chicken embryo fibroblasts. Active potassium transport and the associated specific ouabain binding were shown to be dependent on the cellular growth state but …

Characterization of Attachment and Receptor Isolation of Infectious Pancreatic Necrosis Virus to Chse-214 Cells
… the initial stages of attachment to susceptible cells are not known and are the focus of this research. The attachment of ³⁵S methionine labelled viruses to Chinook Salmon Embryo cells (CHSE-214) was assayed after treatment of the monolayer with various proteolytic enzymes, reducing agents and …

The Effect of Infection with Polyoma Virus on the Protein, RNA, and DNA of Mouse Embryo Cell Cultures
<p>In four separate experiments mouse embryo cell monolayers infected with polyoma virus and uninfected control mouse embryo cells were maintained in Eagle’s Minimum Essential Medium for periods of time ranging from 0 to 168 hours. The cell layers were removed from the glass by trypsinization. …

Increased Apoptosis in the Host By Guanidine Hydrochloride Treatment of Infectious Pancreatic Necrosis Virus
… and cell blebbing. DNA isolates from apoptotic cells typically present a laddering effect on agarose gels. Recent publications indicate the early protein products of some viruses are able to repress apoptosis within their host. Particles or empty capsids that produce inefficient or no protein …

The Structure and Replication of Semliki Forest Virus, A Mosquito-Borne Animal Virus
… to high titer in a number of types of vertebrate cells in culture. The growth of Semliki Forest virus was studied with the electron microscope during a single cycle of viral replication in chick embryo cells. The spherical virus particle consists of a nucleoid, or nucleocapsid, 280 A in diameter, …

Bioinformatics Investigation on the Role of Obox Gene Family in Preimplantation Embryo Development
<p>Preimplantation embryo development (PED) refers to the period from fertilization to implantation in mammals. This complex process is critical for successful implantation and pregnancy. Although studies on PED have been conducted, using mainly the mouse as a model organism, the gene regulatory …

The regulation of tissue proportions: analysis of progenitor behavioural dynamics in response to cell ablation in the zebrafish tailbud.
In order to form a correctly patterned embryo the behaviour of cell populations and tissues must be coordinated so that different structures form with the correct relative proportions. The fundamental body plan of the vertebrate embryo is laid down in a head to tail progression known as primary …

Purification and Activity of the PP60SRC Protein Kinase
<p>Transformation of cells by Rous Sarcoma virus results from the action of a single virally coded phosphoprotein with a molecular weight of 60,000 daltons (pp60<sup>src</sup>). The expression of pp60<sup>src</sup> results in many significant changes in the cell's phenotype which include disruption …
