Frequency of BK Polyoma Virus in Bladder Cancer
The BK virus a member of the Polyomaviruses family was first isolated from the urine of the kidney recipient. Infection with this virus and infection usually occurs in childhood (5-9 years) but most of the time (90%) of sera are positive and without symptoms. Polyomaviruses including the BK virus have also been suggested to be a contributing factor to some cancers in humans such as brain tumors...
متن کاملPolyoma BK Virus: An Oncogenic Virus?
We report a case of a 65-year-old gentleman with a history of end stage renal disease who underwent a successful cadaveric donor kidney transplant four years ago. He subsequently developed BK virus nephropathy related to chronic immunosuppressant therapy. Three years later, misfortune struck again, and he developed adenocarcinoma of the bladder.
متن کاملHost range mutants of polyoma virus.
A line of polyoma-transformed mouse cells has been isolated which is fully susceptible to lytic infection by polyoma virus. This line has been used to select virus mutants which have lost most or all of their ability to grow in the untransformed parental line while retaining the ability to grow in the transformed derivative. These virus mutants are also defective in their ability to transform c...
متن کاملTranscription of a defective polyoma virus genome.
The circular genome of the cloned defective polyoma virus D-50 consists of tandemly repeated copies of the DNA sequence between 67 and 84 units on the wild-type polyoma virus DNA map. Each repeated copy thus contains the origin of viral DNA replication, which is located at about 71 map units. Viral RNA was synthesized in vitro using viral transcription complexes extracted late (30 hr) after inf...
متن کاملImmunological Determinants of Polyoma Virus Oncogenesis
Adult mice and hamsters can be made resistant to an isologous transplantable polyoma tumor by an inapparent infection with polyoma virus. This resistance is cell-mediated and seems not to be related to anti-viral serum antibodies. The basis of the resistance appears to be a transplantation type of cellular immunity directed against a "foreign" antigen contained in the tumor cell. Evidence has b...
