Adenovirus Release from the Infected Cell as a Key Factor for Adenovirus Oncolysis
نویسندگان
چکیده
Adenovirus release is not triggered until late times after viral infection, when the adenovirus death protein (ADP) accumulates to induce viral egress. Thus, the natural rate of adenovirus release may hinder the spread of oncolytic adenoviruses. Several experimental approaches have provided evidence indicating that promoting adenovirus release can be used to enhance their therapeutic potential. This review briefly summarizes what is known about the mechanism of adenovirus release and describes three different strategies, ADP overexpression, apoptosis induction, and bioselection, which can be used to enhance adenovirus release. Finally we will discuss some of the future perspectives that will contribute to the better use of progeny release for the improvement of the antitumor activity of oncolytic adenoviruses.

Characterization of avian adenovirus type-4 causing hydro-pericardium syndrome in broilers in Karachi, Pakistan
Avian adenovirus was isolated from naturally infected birds during 1990 to 2003 in the vicinity ofKarachi, Pakistan. The virus is known to cause hydro-pericardium syndrome (HPS) in poultry. The mortalitywas recorded 20-50% in commercial broilers. Fifty field samples were collected; however, six samples wereselected for molecular studies. These isolates were grown and characterized by cell cultu...

BACKGROUND Adenovirus vectors have lately been highlighted in gene therapies. We investigated the oncolytic effects of a chimeric adenovirus type 5 (Ad5) with replacement of Ad5 fiber knob with adenovirus type 35 (Ad35) fiber knob (Ad5F35) on human renal cell carcinoma (RCC). MATERIALS AND METHODS The conditionally replicating Ad5F35 vector was constructed and infected into RCC cell lines 786...

Objective(s) Recombinant adenoviruses are currently used for a variety of purposes, including in vitro gene transfer, in vivo vaccination, and gene therapy. Ability to infect many cell types, high efficiency in gene transfer, entering both dividing and non dividing cells, and growing to high titers make this virus a good choice for using in various experiments. In the present experiment, a reco...
