Abstract
Forty-one human conjunctival papillomas were histopathologically examined for koilocytosis and papillomavirus common antigen with a peroxidase-antiperoxidase technique immunospecific for genus-specific papillomavirus antigen. Koilocytotic cells, typically found in other papillomavirus-induced tumors, were present in 24 of the 41 specimens. Two of the 41 specimens were positive for viral antigen. The positive reactions were intranuclear within the superficial layers of the epithelium.

Abstract
The DNAs of the human papillomaviruses (HPVs) associated with the benign lesions of two patients suffering from epidermodysplasia verruciformis (patients JD and JK) were analyzed by using 12 restriction endonucleases. None of the restriction endonucleases were one-cut enzymes for the HPV DNA obtained from patient JD, referred to as the prototypical HPV-5, whereas five of them were one-cut enzymes for the DNA of the major virus found in patient JK, referred to as HPV-9. The molecular cloning of the two fragments resulting from the cleavage of HPV-5 DNA by endonuclease HindIII and of the single fragment obtained after treatment of HPV-9 DNA with endonuclease BamHI was performed in Escherichia coli after the fragments were inserted in plasmid pBR322. A cleavage map of the two cloned genomes was constructed. Little sequence homology (4 to 5%) was detected between HPV-5 and HPV-9 DNAs by DNA-DNA hybridization experiments in liquid phase at saturation; this homology was reproducibly higher than that (2 to 3%) detected under the same conditions between these DNAs and HPV-1a DNA. In addition, blot hybridization experiments performed under stringent conditions showed no or little sequence homology between the DNAs of HPV-5 and HPV-9 and those of HPV prototypes of types 1, 2, 3, 4, and 7 associated with skin warts. These results confirm that HPV-5 and HPV-9 are two distinct HPV types.

Abstract
The complete nucleotide sequence of human papillomavirus type 1a (7811 nucleotides) has been established. The overall organization of the viral genome is different from that of other related papovaviruses (SV40, BKV, polyoma). Firstly, genetic information seems to be coded by one strand. Secondly, no significant homology is found with SV40 or polyoma coding sequence for either DNA or deducted protein sequences. The relatedness of human and bovine papillomaviruses is revealed by a conserved coding sequence in the two species. Two regions can be defined on the viral genome: the putative early region contains two large open reading frames of 1446 and 966 nucleotides, together with several split ones, and corresponds to the transforming part of the bovine papillomavirus type 1 genome, and the remaining sequences, which include two open reading frames likely to encode structural polypeptide(s). The DNA sequence is analysed and putative signals for regulation of gene expression, and homologies with the Alu family of human ubiquitous repeats and the SV40 72-bp repeat are outlines.

Abstract
The entire genome of human papilloma virus type 1a was cloned in Escherichia coli using the plasmid pBR322 as vector. The integrity and the homogeneity of the viral DNA thus obtained was confirmed by restriction endonucleases analysis. Viral DNA isolated from a single wart was partially methylated at only one out of the four HpaII sites, d(C-C-G-G). Recognition sites for Bg/I, Bg/II, PstI and PvuII restriction endonucleases were located on the cloned genome.

Abstract
Limited digestion of simian virus 40 (SV40) DNA from both small- and large- plaque strains with the restriction endonuclease Z from Haemophilus aegyptius yielded 10 specific fragments. The number of nucleotide pairs for each fragment, determined by co-electrophoresis with phiX174 RF fragments produced by endonuclease Z, ranges from 2,050 to 80. The difference in the pattern between the large- and small-plaque strains is the disappearance of one fragment containing approximately 255 nucleotide pairs and the appearance of a new fragment with 145 nucleotide pairs. This finding can be explained either by deletions or insertions totaling 110 nucleotide pairs. Complementary RNA synthesized in vitro from the adeno-SV40 hybrid virus, strain ND-1, hybridized preferentially to four of the fragments of SV40 DNA.

Abstract
The time course of replication of simian virus 40 deoxyribonucleic acid (DNA) was investigated in growing monolayer cultures of subcloned CV1 cells. At multiplicities of infection of 30 to 60 plaque-forming units (PFU)/cell, first progeny DNA molecules (component 1) were detected by 10 hr after infection. During the following 10 to 12 hr, accumulation of virus DNA proceeded at ever increasing rates, albeit in a non-exponential fashion. The rate of synthesis then remained constant, until approximately the 40th hour postinfection, when DNA replication stopped. Under these conditions, the duration of the virus growth cycle was approximately 50 hr. The time needed for the synthesis of one DNA molecule was found to be approximately 15 min. At multiplicities of infection of 1 or less than 1 PFU/cell, the onset of the linear phase of DNA accumulation was delayed, but the final rate of DNA synthesis was the same, independent of the input multiplicity. This was taken as a proof that templates for the synthesis of viral DNA multiply in the cell during the early phase of replication. However, the probability for every replicated DNA molecule to become in turn replicative decreased constantly during that phase. This could be accounted for by assuming a limited number of replication sites in the infected cell.

Abstract
The superhelical, closed circular form of polyoma deoxyribonucleic acid (DNA) (Co 1) is bound in a 25S DNA-protein complex to the viral histone-like proteins after alkaline disruption of the virion. Nicked viral DNA or linear DNA are largely free of protein. Most of the viral protein disruption is in the form of capsomeres, sedimenting principally at 10S and 7S. Despite the relatively constant ratio of 10S to 7S material in many preparations, (1:5.5 to 1:6.0, respectively), the two classes of capsomeres are indistinguishable by electron microscopy and contain only P(2), P(3), and P(4) in molar ratios of approximately 5:1:1 or 6:1:1, respectively. Material with sedimentation rates of approximately 1 to 3S is enriched for P(5) and contains small amounts of P(2), P(3), and P(4). During the in vitro reassembly of DNA-free, shell-like particles from disrupted virus, proteins P(1), P(2), P(3), P(4), and P(7) are reincorporated efficiently, whereas P(5) and P(6) are not. The presence in empty reassembled particles of histone-like protein, expecially P(7), implies that at least this one of the minor protein components of the virion may participate in protein-protein interactions with other components of the capsid.

Abstract
Infection of primary or secondary cultures of Chinese hamster embryo cells with simian virus 40 at a multiplicity of 20 to 50 induced synthesis of the virus-specific intranuclear T antigen in 80 to 90% of the cells within 48 to 72 hr. In the infected cultures, 30 to 50% more cells were recruited into deoxyribonucleic acid (DNA) synthesis than in the controls, whether or not the cultures were confluent. The newly synthesized DNA was mostly cellular, since little virus was produced (as shown by various techniques: immunofluorescence for viral antigen, virus growth curves, and isolation of viral DNA from infected cultures). Transformed cells could be detected a few weeks after infection and produced tumors when inoculated into irradiated animals. Chromosomal changes were observed soon after infection (24 hr). Initially, there was a marked increase in the proportion of polyploid cells (8 to 14%), most of which were chromosomally normal. In a few weeks, a large majority of the infected population was polyploid (30 to 50%). Thus, the polyploid cells have the ability to proliferate. Evidence is presented to suggest that polyploid cells arise by stimulation of cells in the G(1), G(2), or S phases to undergo two or more successive periods of DNA synthesis without an intervening mitosis. With a subsequent loss or redistribution of chromosomal material, this may lead eventually to a biologically transformed cell; thus, it is suggested that the initial event(s) relevant to transformation occurs at the level of control of cellular DNA synthesis.
