“…Various strains of type-C oncornaviruses are widespread among species of the animal kingdom and there are a number of reports implicating their presence in human beings. Several laboratories have reported evidence associating type-C oncornavirus with human malignancies by the presence of viral coat proteins, reverse transcriptase, and provirus DNA sequences (DNA copies of the viral RNA genome) in these tissues (7)(8)(9)(10)(11)(12)(13)(14). Isolations of type-C oncornaviruses from cultured human tissues have been reported (15)(16)(17)(18)(19), but are clearly uncommon (20).…”

Single-stranded 3H-DNA probes complementary to the RNA of Rauscher murine leukemia virus and of simian sarcoma virus were prepared using techniques that permitted complete transcription of the viral genome of each virus. These probes were used in DNA-DNA hybridization studies with the cellular DNA from uncultured specimens of spleens and placentas of patients with systemic lupus erythematosus (SLE). No proviral DNA sequences related to these viruses were detected in these tissues. The results presented here do not support previously reported antigenic data implicating type-C oncornavirus infection of these organs in SLE. Type-C oncornaviruses, which belong to the family Retraviridae, consist of a ribonucleoproteifl core enclosed in a lipoprotein envelope that has surface projections of glycoproteins (1-3). The core contains the RNA genome and an RNA-directed-DNA-polymerase (4,5). The presence of this reverse transcriptase enables these viruses to transcribe DNA copies that become integrated into the DNA of the infected host cell (6). Various strains of type-C oncornaviruses are widespread among species of the animal kingdom and there are a number of reports implicating their presence in human beings. Several laboratories have reported evidence associating type-C oncornavirus with human malignancies by the presence of viral coat proteins, reverse transcriptase, and provirus DNA sequences (DNA copies of the viral RNA genome) in these tissues (7-14). Isolations of type-C oncornaviruses from cultured human tissues have been reported (15-19), but are clearly uncommon (20). . .

The dehonst;ation of Cype-C oncornavirus involvement in the pathogenesis Of glomerulonephritis in New Zealand mice (28,29) has led to speculation that this class of virus may be involved in human disease, although more recent studies in mice have contested this association (30,3 1).

“…C-type particles have also been observed by electron microscopy in normal human placentas (8). Sherr and Todaro (9) have found antigens crossreacting with the p30 protein of baboon endogenous virus (BaEV) (10) and RD1 14 virus (11) in two human tumors, while Strand and August (12) have found similar reactivity in various normal and malignant human tissues. Antigenic crossreactivity to oncornavirus p30 protein has also been found in the kidney of a patient with lupus erythematosis (13), while material crossreacting with Mason Pfizer p30 protein has been detected in extracts of human breast cancer cells (14).…”
