Optimized riboswitch-regulated AAV vector for VEGF-B gene therapy.

Gene therapy would greatly benefit from a method to regulate therapeutic gene expression temporally. Riboswitches are small RNA elements that have been studied for their potential use in turning transgene expression on or off by ligand binding. We compared several tetracycline and toyocamycin-inducible ON-riboswitches for a drug responsive transgene expression.

Parvovirus nonstructural protein 2 interacts with chromatin-regulating cellular proteins.

Autonomous parvoviruses encode at least two nonstructural proteins, NS1 and NS2. While NS1 is linked to important nuclear processes required for viral replication, much less is known about the role of NS2. Specifically, the function of canine parvovirus (CPV) NS2 has remained undefined.

Functional roles of the membrane-associated AAV protein MAAP.

With a limited coding capacity of 4.7 kb, adeno-associated virus (AAV) genome has evolved over-lapping genes to maximise the usage of its genome. An example is the recently found ORF in the cap gene, encoding membrane-associated accessory protein (MAAP), located in the same genomic region as the VP1/2 unique domain, but in a different reading frame.

Comparative Study of Adeno-associated Virus, Adenovirus, Bacu lovirus and Lentivirus Vectors for Gene Therapy of the Eyes.

Background: The eye possesses unique anatomical features that make it a valuable target for gene therapy applications.

Objective: The aim of the current study was to compare transduction efficiency, safety and biodistribution of four viral vectors following intravitreal injection.

Method: Adenovirus (AdV), Adeno-Associated Virus (AAV), Baculovirus (BV) and Lentivirus (LV) vectors encoding Green Fluorescent Protein (GFP) were injected bilaterally intravitreally into adult C57BL/6OlaHsd mice.
