Common antigen in meningioma-derived cell cultures.

Serums of patients with intracranial meningiomas reacted in immunofluorescence assays with cell cultures and tumor imprints prepared from human meningiomas. Antibody in these serums appears to be specific for antigens in meningioma tissue and shows some cross-reactivity with neoplastic tissue of glial origin.

DNA polymerase activities in varions of visna virus, a causative agent of a "slow" neurological disease.

The presence is reported of an RNA-instructed DNA polymerase in visna virus, the causative agent of a "slow" neurological disease in sheep. The product synthesized by the RNA-directed reaction has been shown to be a DNA heteropolymer by the following criteria: synthesis requires the presence of all four deoxyriboside triphosphates; the product is resistant to ribonuclease and alkali but is degraded by DNase; and the product has a density of 1.420 in Cs(2)SO(4) solution, characteristic of DNA.Visna virions, like those of the oncogenic RNA viruses, contain DNA polymerase activities that respond to a variety of double-stranded DNAs and to synthetic DNA.RNA hybrids.
