Biological characteristics of gene expression features in pancreatic cancer cell induced by proton and x-ray irradiation IV

The aim of the study is to disclose the distinct alteration of biological characteristics of gene expression features in pancreas cancer cell, MIAPaCa-2, irradiated by proton and x-ray. The survived MIAPaCa-2 cells after irradiation with proton and x-ray were isolated and gene expression profiles were analyzed. MIAPaCa-2 cells after x-ray irradiation were expanded. The expanded cells were either re-irradiated by proton with 8 Gy (n=4) or not irradiated (n=4). After 4 hours, RNA was extracted, followed by gene expression analysis.
