Early RNA of adenovirus type 3 in permissive and abortive infections.
نویسندگان
چکیده
Early adenovirus type 3 cytoplasmic polyadenylated RNAs from HeLa and BHK-21 cells were detected and mapped on the viral genome by gel blotting and hybridization techniques. The sizes and locations of the 16 adenovirus type 3 RNAs were identical in the two cell types, although relative molarities of the various RNA species differed. Each of the early adenovirus type 3 RNAs was associated with polysomes in both cell types, suggesting that the abortive infection of hamster cells does not result from a defect in early adenovirus type 3 mRNA biosynthesis. No RNAs from regions transcribed late in infection of permissive cells were detected in BHK-21 cells.

متن کاملAltered expression of adenovirus 12 DNA-binding protein but not DNA polymerase during abortive infection of hamster cells.
Replication of human adenovirus type 12 DNA is blocked in abortively infected baby hamster kidney cells. The activity and accumulation of adenovirus 12 DNA polymerase is equivalent in infected hamster and human cell extracts. However, the accumulation of adenovirus type 12 DNA-binding protein is approximately 120-fold lower in extracts from infected hamster cells when compared to infected permi...
متن کاملTranscriptional blocks limit adenoviral replication in primary ovarian tumor.
PURPOSE Despite the success of conditionally replicating adenoviruses in tumor models, clinical success has been limited when they are used as a single modality agent. Overcoming the disparity in efficacy between in vivo animal models and human use is a key hurdle for better conditionally replicating adenovirus therapy in humans. We endeavored to identify biological blocks to adenoviral infecti...
متن کاملAbortive initiation is increased only for the weakest members of a set of down mutants of the adenovirus 2 major late promoter.
We have shown that accurate initiation of productive RNA synthesis in vitro at the adenovirus 2 major late promoter is accompanied by abortive initiation of very short transcripts (Luse, D. S., and Jacob, G. A. (1987) J. Biol. Chem. 262, 14990-14997). We made a set of sequence variants of this promoter, using every possible base at position -28 (in the TATA box) in the context of either the nor...

Adenovirus infections of immunocompromised pediatric hematopoietic stem cell transplant patients can develop into serious and often deadly multi-organ disease. There are no drugs approved for adenovirus infections. Cidofovir (an analog of 2-deoxycytidine monophosphate) is used at times but it can be nephrotoxic and its efficacy has not been proven in clinical trials. Brincidofovir, a promising ...
