有丝分裂染色体结构一直是细胞生物学中的一个“谜,包裹在一个谜中,在一个谜”。观察到基因敲除或敲低凝聚素亚基或拓扑异构酶II只会导致最小的扰动,在整体染色体凝聚,再加上分析的早期阶段的染色体凝聚和组蛋白H1耗尽产生的影响,建议有必要重新考虑教科书模型的有丝分裂染色体凝聚和组织。
Mitotic chromosome structure has been the cell biology equivalent of a 'riddle, wrapped in a mystery, inside an enigma'. Observations that genetic knockout or knockdown of condensin subunits or topoisomerase II cause only minimal perturbation in overall chromosome condensation, together with analysis of early stages of chromosome condensation and effects produced by histone H1 depletion, suggest a need to reconsider textbook models of mitotic chromosome condensation and organization.
