Abstract

In contrast to total cell irradiation, local UV-microbeam irradiation can stimulate a significant diminution in the irradiated mature nucleoli in interphase mammalian cells in culture. This diminution is accompanied by the concomitant expansion of the unirradiated nucleoli within the same nucleus, and the total nucleolar volume per nucleus does not change appreciably. It is suggested that these nucleolar volume changes are the result of the dispersion, migration, and redistribution of the nucleolar material between competitive nucleolar organizer regions of the interphase nucleus.

摘要

与全细胞照射相比，局部紫外线微束照射可促使培养的间期哺乳动物细胞中受照射的成熟核仁显著缩小。这种缩小伴随着同一细胞核内未受照射核仁的相应扩大，且每个细胞核的总核仁体积没有明显变化。有人认为，这些核仁体积变化是核仁物质在间期细胞核竞争性核仁组织区之间分散、迁移和重新分布的结果。
