内容記述 | Heavy ion beams are a high-LET radiation that has greater biological effect than electron beams or X-rays. However, little is known about the effect of heavy ion beams on the proliferation and differentiation of human hematopoietic stem/progenitor cells (HSPCs). The present study examined the effect of heavy ion beams on gene expression in human HSPCs, especially during early stage of megakaryocytopoiesis. Human CD34+ cells were exposed to monoenergetic carbon-ion beams (290 MeV/nucleon, LET = 50 KeV/um) that were generated by an accelerator (Heavy Ion Medical Accelerator in Chiba). The expression of various genes related to early hematopoiesis, megakaryocytopoiesis/erythropoiesis, cytokine receptors and oxidative stress were analyzed by real-time RT-PCR. Friend leukemia virus integration 1, an early hematopoiesis-related gene, showed significantly higher mRNA expression than the control at 6 hr after irradiation. In contrast, no significant differences were observed in almost all of the other early hematopoiesis-related genes, cytokine receptor-coded genes and megakaryocytopoiesis/erythropoiesis-differentiation pathway-related genes, respectively. An analysis of the response of the genes to oxidative stress revealed the expression of heme oxygenase 1 to show a 1.5-fold and 11.9-fold increase from the day 0 control at 24 hr after 0.5 Gy and 2 Gy irradiation, respectively. Similarly, the NAD(P)H dehydrogenase-quinone 1 expression also showed a 22.0-fold and a 21.8-fold increase at 6 hr in comparison to the initial control. These results showed that the heavy ion beams affect megakaryocytopoiesis/erythropoiesis differentiation of human HSPCs on the gene expression level. | |||||
