Replicative intermediate of hepatitis B virus in transfected murine fibroblasts. 1987

A Z Zelent, and M A Sells, and M Shvartsman, and P M Price, and G Acs

The NIH 3T3-derived cell line psi AM22b, which carries a defective Moloney murine leukemia virus, was transfected with a plasmid carrying the neo gene and two head-to-tail copies of the hepatitis B virus (HBV) genome positioned with opposing polarities. Both the two HBV dimers and the neo gene were located between two Moloney murine leukemia virus long terminal repeats. Poly(A)+ RNAs isolated from one clone that grew in the presence of G418 contained the two major classes of HBV-specific transcripts (3.5-kilobase pregenome and 2.1-kilobase mRNAs) in approximately equivalent amounts, which was reminiscent of the profiles of viral mRNAs from the livers of infected humans and chimpanzees.

UI MeSH Term Description Entries
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D004279 DNA, Viral Deoxyribonucleic acid that makes up the genetic material of viruses. Viral DNA
D005347 Fibroblasts Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules. Fibroblast
D005814 Genes, Viral The functional hereditary units of VIRUSES. Viral Genes,Gene, Viral,Viral Gene
D006515 Hepatitis B virus The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum. Dane Particle,Hepatitis Virus, Homologous Serum,B virus, Hepatitis,Hepatitis B viruses,Particle, Dane,viruses, Hepatitis B
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012367 RNA, Viral Ribonucleic acid that makes up the genetic material of viruses. Viral RNA
D014158 Transcription, Genetic The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION. Genetic Transcription
D014162 Transfection The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES. Transfections
D014779 Virus Replication The process of intracellular viral multiplication, consisting of the synthesis of PROTEINS; NUCLEIC ACIDS; and sometimes LIPIDS, and their assembly into a new infectious particle. Viral Replication,Replication, Viral,Replication, Virus,Replications, Viral,Replications, Virus,Viral Replications,Virus Replications
