The results of this study confirm that adenoviruses are the most resistant enteric viruses to inactivation by UV light and that adenovirus 40 appears to be the most resistant. The effect of freeze-thawing and storage in water may affect the sensitivity of some adenoviruses to inactivation by UV light.

A central quest in gene therapy and vaccination is to achieve effective long-lasting expression at minimal dosage. Adenovirus vectors are widely used therapeutics safely deliver genes into many cell types. Adenoviruses evolved use elaborate trafficking particle deconstruction processes, efficient progeny formation. Here, we discuss recent insights how human adenoviruses their double-stranded DN...

Production of an interferon-like substance was demonstrated in primary chick embryo cells inoculated with human adenoviruses. In this rescept various examined types behaved similarly. Treatment of the virus with homologous immune serum, heat or trypsin resulted in the loss of its inducing capacity. The presence of mycoplasma had no influence on the induction of the interferonlike substance due ...

BACKGROUND When recombinant adenoviruses are infused directly into the circulation, transgene expression is almost completely restricted to the liver. AIMS Efficiency and safety of adenovirus mediated gene transfer into damaged livers were examined in mice with liver cirrhosis or fulminant hepatitis. METHODS Liver cirrhosis and fulminant hepatitis were induced by intraperitoneal administrat...

We closely mimicked the in vivo setting in which sporadic hepatocarcinoma occurs by establishing a transgenic mouse model carrying regulatable SV40 early sequences under the control of the regulatory sequences of the human antithrombin III gene that confer hepatic expression. In this system, floxed dormant oncogenic sequences became functional after excision due to adenoviral expression of Cre ...

At least 70% of plus or minus strands of adenovirus-associated virus DNA contain self-complementary sequences at or near their termini. Self-annealing of these sequences generates circular molecules that are closed by duplex, hydrogen-bonded segments. The self-annealed segments are sensitive to exonuclease III and have a thermal stability comparable to that of double-stranded DNA molecules. Len...

The acquisition of the defective SV40 genome by a variety of human adenovirus serotypes by the process of transcapsidation has resulted in the addition of oncogenic potential for newborn hamsters to the previously nononcogenic adenovirus types 1, 2, 5, and 6. These serotypes have previously been grouped together by the high GC content of their DNA. Transcapsidation of the SV40 genome to weakly ...
