Pattern Formation of Glioma Cells: Effects of Adhesion (2008)

Khain, Evgeniy, Nowicki, Michal O., Chiocca, E. Antonio, Lawler, S. E., Sander, Leonard M.

Glioblastoma multiforme is a malignant brain tumor. We investigate the clustering of glioma cells in vitro in order to shed light on brain tumor formation. In vitro experiments in a gel found a cell...

Nowicki, Michal O., Dmitrieva, Nina, Stein, Andrew M., Cutter, Jennifer L., Godlewski, Jakub, Saeki, Yoshinaga, ...

Therapies targeting glioma cells that diffusely infiltrate normal brain are highly sought after. Our aim was to identify novel approaches to this problem using glioma spheroid migration assays....

Effect of Tumor Microenvironment Modulation on the Efficacy of Oncolytic Virus Therapy (2007)

Kurozumi, Kazuhiko, Hardcastle, Jayson, Thakur, Roopa, Yang, Ming, Christoforidis, Gregory, Fulci, Giulia, ...

Background The tumor microenvironment is being increasingly recognized as an important determinant of tumor progression as well as of therapeutic response. We investigated oncolytic virus (OV)...

B-myb Promoter Retargeting of Herpes Simplex Virus γ34.5 Gene-Mediated Virulence toward Tumor and Cycling Cells

Chung, Richard Y., Saeki, Yoshinaga, Chiocca, E. Antonio

Deletion of the γ34.5 gene coding for virulence markedly reduces cytotoxicity mediated by herpes simplex virus type 1 (HSV-1) (J. M. Markert et al., Neurosurgery 32:597–603, 1993; N. S. Markovitz...

Complement Depletion Facilitates the Infection of Multiple Brain Tumors by an Intravascular, Replication-Conditional Herpes Simplex Virus Mutant

Ikeda, Keiro, Wakimoto, Hiroaki, Ichikawa, Tomotsugu, Jhung, Sarah, Hochberg, Fred H., Louis, David N., ...

Intravascular routes of administration can provide a means to target gene- and virus-based therapies to multiple tumor foci located within an organ, such as the brain. However, we demonstrate here...

Single-Step Conversion of Cells to Retrovirus Vector Producers with Herpes Simplex Virus–Epstein-Barr Virus Hybrid Amplicons

Sena-Esteves, Miguel, Saeki, Yoshinaga, Camp, Sara M., Chiocca, E. Antonio, Breakefield, Xandra O.

We report here on the development and characterization of a novel herpes simplex virus type 1 (HSV-1) amplicon-based vector system which takes advantage of the host range and retention properties of...

Regulation of herpes simplex virus γ134.5 expression and oncolysis of diffuse liver metastases by Myb34.5

Nakamura, Hideo, Kasuya, Hideki, Mullen, John T., Yoon, Sam S., Pawlik, Timothy M., Chandrasekhar, Soundararajalu, ...

Myb34.5 is a herpes simplex virus 1 (HSV-1) mutant deleted in the gene for ribonucleotide reductase (ICP6). It also carries a version of γ134.5 (a viral gene product that promotes the...

Functional Response of Tumor Vasculature to PaCO2: Determination of Total and Microvascular Blood Volume by MRI

Packard, Scott D, Mandeville, Joseph B, Ichikawa, Tomotsugu, Ikeda, Keiro, Terada, Kinya, Niloff, Stephanie, ...

In order to identify differences in functional activity, we compared the reactivity of glioma vasculature and the native cerebral vasculature to both dilate and constrict in response to altered...

MRI of Transgene Expression: Correlation to Therapeutic Gene Expression

Ichikawa, Tomotsugu, Högemanny, Dagmar, Saeki, Yoshinaga, Tyminski, Edyta, Terada, Kinya, Weissleder, Ralph, ...

Magnetic resonance imaging (MRI) can provide highresolution 3D maps of structural and functional information, yet its use of mapping in vivo gene expression has only recently been explored. A...
