Isolation and characterization of cell lines derived from hamster kidney cells transformed by BK virus, and transforming activity of their DNA. 1983

L Possati, and G Ciarallo, and A Collesi, and C Rubini

Eight cell lines obtained from BK virus-transformed hamster kidney cells were characterized by some biological parameters as presence of BKV T antigen, growth properties and tumourigenicity. The transforming ability of their DNA on primary foetal rat fibroblasts was then studied, and transformed rat cells were characterized by the same biological parameters as above. Transformed hamster cells showed no correlation among presence of virus, growth properties and tumourigenicity; DNA from normal hamster kidney cells and from two BKV-transformed cell lines induced transformation on rat fibroblasts, but presence of BKV T antigen was detected only in one DNA-transformed rat cell line. The role of cellular and viral genes on neoplastic transformation is discussed.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D001739	BK Virus	A species of POLYOMAVIRUS apparently infecting over 90% of children but not clearly associated with any clinical illness in childhood. The virus remains latent in the body throughout life and can be reactivated under certain circumstances.

D002471	Cell Transformation, Neoplastic	Cell changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm, and other attributes conferring the ability to invade, metastasize, and kill.

D006224	Cricetinae	A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.	Cricetus,Hamsters,Hamster
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.

D000957	Antigens, Viral, Tumor	Those proteins recognized by antibodies from serum of animals bearing tumors induced by viruses; these proteins are presumably coded for by the nucleic acids of the same viruses that caused the neoplastic transformation.

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
