Recombinant adenovirus-mediated gene transfer into the adult rat retina

Current Eye Research

Abstract

The present study was designed to evaluate the feasibility of gene transfer into the retina of adult rats, using a recombinant replication-defective adenovirus vector expressing a reporter gene. Purified recombinant adenovirus expressing beta-galactosidase (lacZ) (Ad5.hCMV.lacZ) at doses ranging from 1.4 x 10(2) to 1.4 x 10(6) plaque-forming units (pfu) were injected into the subretinal space of adult Lewis rats. The presence of lacZ was determined by histochemical assay and reverse transcription and polymerase chain reaction analysis (RT PCR) of total RNA extracted from eyes injected with recombinant adenovirus expressing lacZ. As assessed by biomicroscopy, the expression of lacZ was highest in the retinal pigment epithelium in a localized area corresponding to the site of injection. The level of lacZ expression was correlated with the amount of virus delivered to the subretinal space. Persistent but decreasing expression of lacZ was noted over time. RT PCR revealed the expression of messenger RNA for at least sixty days. The results of this study demonstrate that efficient and stable transfer of genetic material into the subretinal space of adult rats may be achieved using a recombinant adenoviral vector. The use of such vect...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
