A dual function fusion protein of Herpes simplex virus type 1 thymidine kinase and firefly luciferase for noninvasive in vivo imaging of gene therapy in malignant glioma

PCR detection of thymidine kinase gen of latent herpes simplex Virus type 1 in mice trigeminal ganglia

  Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

Restriction Enzyme Analysis of Thymidine Kinase Gene in Four Iranian Isolates of Herpes Simplex Virus Type 1

In vitro Interaction of HSV-1 ORF P with Both Thymidine Kinase (TK) and an Unidentified Cellular Protein

Herpes simplex virus type-1 (HSV-1) is a neurotropic pathogen of humans that establishes latent infection in the sensory ganglia innervating the site of primary infection. A number of genes control HSV-1 pathogenicity and latency. Open reading frame P (ORF P) is one of these genes that might have a role in latency and pathogenesis. A complication in the analysis of the role of ORF P in the HSV-...

Rational Design of a Triple Reporter Gene for Multimodality Molecular Imaging

Multimodality imaging using noncytotoxic triple fusion (TF) reporter genes is an important application for cell-based tracking, drug screening, and therapy. The firefly luciferase (fl), monomeric red fluorescence protein (mrfp), and truncated herpes simplex virus type 1 thymidine kinase SR39 mutant (ttksr39) were fused together to create TF reporter gene constructs with different order. The enz...

Positron emission tomography imaging of cardiac reporter gene expression in living rats.

BACKGROUND Imaging reporter gene expression is useful for noninvasive monitoring of gene therapy. In this study, we imaged cardiac reporter gene expression in living rats using micro positron emission tomography (microPET). METHODS AND RESULTS Rats (n=10) underwent intramyocardial injection with 1x10(9) pfu of adenovirus carrying cytomegalovirus promoter-driving herpes simplex virus type 1 mu...
