Vascular endothelial growth factor (VEGF) mRNA isoform expression pattern is correlated with liver metastasis and poor prognosis in colon cancer.

Tokunaga, T., Oshika, Y., Abe, Y., Ozeki, Y., Sadahiro, S., Kijima, H., ...

Vascular endothelial growth factor (VEGF) is a well known factor that induces angiogenesis. Four isoforms, i.e. VEGF206, 189, 165, and 121, have been identified. We examined the isoform patterns of...

Comparison of radiobiological effective depths in 65-MeV modulated proton beams.

Tang, J. T., Inoue, T., Inoue, T., Yamazaki, H., Fukushima, S., Fournier-Bidoz, N., ...

To assess the achievement of uniformity of radiobiological effectiveness at different depths in the proton spread-out Bragg peak (SOBP), Chinese hamster ovary (CHO) cells were exposed to 65-MeV...

Murine P-glycoprotein on stromal vessels mediates multidrug resistance in intracerebral human glioma xenografts.

Takamiya, Y., Abe, Y., Tanaka, Y., Tsugu, A., Kazuno, M., Oshika, Y., ...

Human glioma usually shows intrinsic multidrug resistance because of the blood-brain barrier (BBB), in which membrane-associated P-glycoprotein (P-gp), encoded by the human multidrug resistance gene...

Thrombospondin 2 expression is correlated with inhibition of angiogenesis and metastasis of colon cancer

Tokunaga, T, Nakamura, M, Oshika, Y, Abe, Y, Ozeki, Y, Fukushima, Y, ...

Two subtypes of thrombospondin (TSP-1 and TSP-2) have inhibitory roles in angiogenesis in vitro, although the biological significance of these TSP isoforms has not been determined in vivo. We...

Ribozyme-mediated inactivation of mutant K-ras oncogene in a colon cancer cell line

Tokunaga, T, Tsuchida, T, Kijima, H, Okamoto, K, Oshika, Y, Sawa, N, ...

Mutation of c-K-ras oncogene is an important step in progression of colon cancer. We used a hammerhead ribozyme (KrasRz) against mutated K-ras gene transcripts (codon 12, GTT) to inactivate mutant...
