中文摘要
该计划基于我们最新的基础研究,这些研究已经改变了辐射生物学的范式,并证明了大脑对低剂量辐射(LDR)暴露高度敏感。最近,我们报道了头部LDR照射引起受照动物前额叶皮质DNA损伤并影响基因表达。我们还证实了肝脏照射后脑内存在旁观者效应。头部和肝脏照射都降低了脊椎密度、树突复杂性和树突长度,并改变了行为。此外,分批接触LDR还会造成DNA损伤,改变全球基因组甲基化,并诱导行为改变。
英文摘要
The program is based on our most recent fundamental studies that have shifted the paradigm of radiation biology and proved that the brain is highly sensitive to low dose radiation (LDR) exposure. Recently, we reported that head LDR exposure induced DNA damage and affected gene expression in the prefrontal cortex of irradiated animals. We also proved that bystander effects exist in the brain after liver irradiation. Both head and liver irradiation reduced spine density, dendritic complexity and dendritic length and altered behavior. Moreover, fractionated LDR exposure also caused DNA damage, altered global genomic methylation and induced behavioral changes.
