| Outline of Final Research Achievements |
The study conducted a hypoxial PET (positron emission tomography) and obtained tissue from a region diagnosed as a hypoxic region in glioblastoma tissue and from other regions. When the study cultured each tumor tissue and analyzed a factor related to oxidant stress such as HIF-1α with RT-PCR, it evidently found a influence by hypoxia in vivo.
The study compered responsiveness of anticancer drug between tumor in hypoxic region and other regions, but there was no significant difference. However, it was suggested that there was a difference in expression level of gene repair enzyme at each region and also a possible difference in effectiveness of anticancer drug under hypoxic stress.
