They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.

Late transcription and simultaneous replication of simian adenovirus 7 DNA as revealed by spreading lytically infected cell cultures. (1/60)
Miller's technique of spreading DNA was applied to monkey cells productively infected with simian adenovirus 7. This permitted the visualization of cellular DNA transcription, both nucleolar and non-nucleolar, and of late transcription and replication of virus. Virus double-stranded DNA, thin fibres with very few nucleosome-like particles, were observed carrying either transcription or replication complexes. In addition, both RNP transcripts and replication forks were found on some virus duplex DNA. Virus single-stranded DNA replicative intermediates were identified on the basis of their increased thickness and contrast which results from the presence of a DNA binding protein. (+info)Biological activity of the intact and cleaved DNA of the simian adenovirus 7. (2/60)
Only the deproteinized DNA preparations of the simian adenovirus of the type 7 (SA 7) exhibited transforming and tumorigenic activity. The complex of the SA7 DNA with terminal protein (TP) did not exhibit either transforming or tumorigenic activity in cell cultures. In contrast to the transforming potential the infectious titers of the DNA - TP complex for the monkey kidney cells were 30-50 times higher than those of pure DNA. Cleavage of the SA7 DNA by specific endonucleases enhanced the tumorigenic potential of pure DNA, suppressed its infectivity and did not affect the lack of transformation capacity of the DNA - TP complex. The onc-gene was localized in the left terminal fragment with the minimal size 4,3x10(6)D in the case of R.Sal I. The tumorigenic activity was found to decrease with an increase in the size of the DNA fragment containing the onc-gene. (+info)Chimpanzee adenovirus CV-68 adapted as a gene delivery vector interacts with the coxsackievirus and adenovirus receptor. (3/60)
A replication-defective form of chimpanzee adenovirus type 68 (C68) has been developed to circumvent problems posed by widespread preexisting immunity to common human adenovirus vectors. To investigate the determinants of C68 tropism, its interaction with the coxsackievirus and adenovirus receptor (CAR) was studied. Although CHO cells were resistant to transduction by C68 as well as by adenovirus type 5 (Ad5), CHO cells expressing either human or murine CAR were transduced readily. C68 transduction, like Ad5 transduction, was blocked when cells were exposed to anti-CAR antibody or when virus was exposed to a soluble form of the CAR extracellular domain. These results indicate that gene delivery by C68 occurs by a CAR-dependent mechanism. (+info)Novel, chimpanzee serotype 68-based adenoviral vaccine carrier for induction of antibodies to a transgene product. (4/60)
An E1-deletion-containing adenoviral recombinant based on the chimpanzee serotype 68 (AdC68) was developed to express the rabies virus glycoprotein. Mice immunized with this construct (AdC68rab.gp) developed antibodies to rabies virus and remained resistant to challenge with an otherwise lethal dose of rabies virus. In naive mice immunized intranasally, the rabies virus-specific antibody responses elicited by AdC68rab.gp were comparable with regard to both titers and isotype profiles to those induced by an adenoviral recombinant based on human serotype 5 (Adhu5) expressing the same transgene product. In contrast, subcutaneous immunization with the AdC68rab.gp vaccine resulted in markedly lower antibody responses to the rabies virus glycoprotein than the corresponding Adhu5 vaccine. Antibodies from AdC68rab.gp-immunized mice were strongly biased towards the immunoglobulin G2a isotype. The antibody response to the rabies virus glycoprotein presented by Adhu5rab.gp was severely compromised in animals preexposed to the homologous adenovirus. In contrast, the rabies virus-specific antibody response to the AdC68rab.gp vaccine was at most marginally affected by preexisting immunity to common human adenovirus serotypes, such as 2, 4, 5, 7, and 12. This novel vaccine carrier thus offers a distinct advantage over adenoviral vaccines based on common human serotypes. (+info)Comparative sequence analysis of the largest E1A proteins of human and simian adenoviruses. (5/60)
The early region 1A (E1A) gene is the first gene expressed after infection with adenovirus and has been most extensively characterized in human adenovirus type 5 (hAd5). The E1A proteins interact with numerous cellular regulatory proteins, influencing a variety of transcriptional and cell cycle events. For this reason, these multifunctional proteins have been useful as tools for dissecting pathways regulating cell growth and gene expression. Despite the large number of studies using hAd5 E1A, relatively little is known about the function of the E1A proteins of other adenoviruses. In 1985, a comparison of E1A sequences from three human and one simian adenovirus identified three regions with higher overall levels of sequence conservation designated conserved regions (CR) 1, 2, and 3. As expected, these regions are critical for a variety of E1A functions. Since that time, the sequences of several other human and simian adenovirus E1A proteins have been determined. Using these, and two additional sequences that we determined, we report here a detailed comparison of the sequences of 15 E1A proteins representing each of the six hAd subgroups and several simian adenoviruses. These analyses refine the positioning of CR1, 2, and 3; define a fourth CR located near the carboxyl terminus of E1A; and suggest several new functions for E1A. (+info)A simian replication-defective adenoviral recombinant vaccine to HIV-1 gag. (6/60)
In animal models, E1-deleted human adenoviral recombinants of the serotype 5 (AdHu5) have shown high efficacy as vaccine carriers for different Ags including those of HIV-1. Humans are infected by common serotypes of human adenovirus such as AdHu5 early in life and a significant percentage has high levels of neutralizing Abs to these serotypes, which will very likely impair the efficacy of recombinant vaccines based on the homologous virus. To circumvent this problem, a novel replication-defective adenoviral vaccine carrier based on an E1-deleted recombinant of the chimpanzee adenovirus 68 (AdC68) was developed. An AdC68 construct expressing a codon-optimized, truncated form of gag of HIV-1 induces CD8(+) T cells to gag in mice which at the height of the immune response encompass nearly 20% of the entire splenic CD8(+) T cell population. The vaccine-induced immune response provides protection to challenge with a vaccinia gag recombinant virus. Induction of transgene-specific CD8(+) T cells and protection against viral challenge elicited by the AdC68 vaccines is not strongly inhibited in animals preimmune to AdHu5 virus. However, the response elicited by the AdHu5 vaccine is greatly attenuated in AdHu5 preimmune animals. (+info)Complete nucleotide sequences and genome organization of four chimpanzee adenoviruses. (7/60)
The complete nucleotide sequences for four adenoviruses-Simian Adenoviruses 21, 22, 23, and 24, originally isolated from chimpanzees, were determined. The genome organization of the chimpanzee adenoviruses was found to be similar to that of other adenoviruses. The viral gene products of the adenoviruses Simian Adenoviruses 22, 23, and 24 are very closely related to those of the (previously sequenced) chimpanzee adenovirus Simian Adenovirus 25. Simian Adenovirus 21 is most similar to human subgroup B adenoviruses HAdV-3, HAdV-7, and HAdV-35. Analysis of the capsid proteins hexon and fiber of the chimpanzee adenoviruses also supports the placement of Simian Adenovirus 21 in subgroup B and Simian Adenoviruses 22, 23, and 24 in subgroup E. (+info)Analysis of the first complete genome sequence of an Old World monkey adenovirus reveals a lineage distinct from the six human adenovirus species. (8/60)
Simian adenovirus 3 (SAdV-3) is one of several adenoviruses that were isolated decades ago from Old World monkeys. Determination of the complete DNA sequence of SAdV-3 permitted the first full genomic comparison of a monkey adenovirus with adenoviruses of humans (HAdVs) and chimpanzees, which are recognized formally as constituting six of the species (HAdV-A to HAdV-F) within the genus Mastadenovirus. The SAdV-3 genome is 34 246 bp in size and has a G+C content of 55.3 mol%. It contains all the genes that are characteristic of the genus Mastadenovirus and has a single VA-RNA gene and six genes in each of the E3 and E4 regions. The genetic organization is the same as that of HAdV-12, a member of the HAdV-A species. Phylogenetic analyses showed that although SAdV-3 is related marginally more closely to HAdV-A and HAdV-F than to other species, it represents a unique lineage that branched at an early stage of primate adenovirus divergence. The results imply that the genetic layout in SAdV-3 and HAdV-12 may also have characterized the common ancestor of all sequenced primate adenoviruses. (+info)
