Targeting Adenovirus Vectors

Fiber-Modified Adenovirus Vectors Decrease

Canine adenovirus vectors: an alternative for adenovirus-mediated gene transfer.

Preclinical studies have shown that gene transfer following readministration of viral vectors is often inefficient due to the presence of neutralizing antibodies. Vectors derived from ubiquitous human adenoviruses may have limited clinical use because preexisting humoral and cellular immunity is found in 90% of the population. Furthermore, risks associated with the use of human adenovirus vecto...

Transcriptional targeting modalities in breast cancer gene therapy using adenovirus vectors controlled by alpha-lactalbumin promoter.

The breast-specific antigen alpha-lactalbumin is expressed in >60% of breast cancer tissues. To evaluate the effect of gene therapy for breast cancer by controlling adenovirus replication with human alpha-lactalbumin promoter, we investigated the activity of a 762-bp human alpha-lactalbumin promoter. Alpha-lactalbumin promoter showed significantly higher activity in MDA-MB-435S and T47D breast ...

Targeting of adenovirus vectors to tumor cells does not enable efficient transduction of breast cancer metastases.

Targeting of oncolytic adenoviruses to tumors can potentially increase their efficacy and safety profile after systemic application. We have developed recently a capsid-modified vector containing the adenovirus serotype 35 fiber shaft and knob inserted into an Ad5 capsid. This Ad5/35 vector infects cells via a coxsackievirus adenovirus receptor-independent pathway. Here we attempted to exploit ...
