中文摘要
在中子俘获治疗中,选择性地将硼掺入肿瘤细胞中是重要的。本研究采用流式细胞仪对细胞进行G 0/G1期和G2/M期分选,并采用ICP-AES测定各组分中硼浓度。结果表明,BSH和BPA在G2/M中的硼吸收速率高于G 0/G1。然而,BPA的差异更为突出。G2/M:G 0/G1比值随着BPA培养时间的变化而降低,从而表明BPA摄取的细胞周期依赖性。肿瘤细胞硼吸收的这种异质性应考虑微剂量学。
英文摘要
In neutron capture therapy, it is important to incorporate boron in tumor cells selectively. The present study used flow cytometry to sort the cells by G0/G1 phase and G2/M phase, and the boron concentration of each fraction was measured with ICP-AES. The results revealed that BSH and BPA, had higher rates of boron uptake in the G2/M than in the G0/G1. However, the difference was more prominent with BPA. The G2/M : G0/G1 ratio decreased as a function of time in culture in BPA, thereby indicating the cell cycle dependency of BPA uptake. Such heterogeneity of boron uptake in tumor cells should be considered for microdosimetry.
