Conrad et al. (Reports, 10 August 2012, p. 742) reported a doubling of RNA polymerase II (Pol II) occupancy at X-linked promoters to support 5' recruitment as the key mechanism for dosage compensation in Drosophila. However, they employed an erroneous data-processing step, overestimating Pol II differences. Reanalysis of the data fails to support the authors' model for dosage compensation.
康拉德等人(2012 年 8 月 10 日,第 742 页)在报告中指出,RNA 聚合酶 II(Pol II)在 X 连锁启动子上的占有率增加了一倍,以支持 5'募集,这是果蝇中剂量补偿的关键机制。然而,他们采用了一个错误的数据处理步骤,高估了 Pol II 的差异。对数据的重新分析不支持作者提出的剂量补偿模型。
