The previous report shows the minimal promoter (P1) contributes to the RNA activation in cells, while the role of the P1 has not yet been investigated in animal individuals. Here, female P1 knockout rabbits ( P1) were generated for the studies. The results showed that there is no significant difference in transmission ratio, and X-linked genes expression, and RNA localization between the female wild type (WT) and P1 rabbits, suggesting that P1 is non-essential for expression and XCI in rabbits. Our study has explored the function of P1 in animal level for the first time, and the results provide new ideas for future studies of XCI mechanisms.
先前的报告表明,微启动子(P1)有助于细胞中的 RNA 激活,而 P1 在动物个体中的作用尚未得到研究。在这里,我们生成了雌性 P1 敲除兔(P1)以进行研究。结果表明,雌性野生型(WT)和 P1 兔之间的传递率、X 连锁基因表达和 RNA 定位没有显著差异,这表明 P1 对于兔的表达和 XCI 并非必需。我们的研究首次在动物水平上探索了 P1 的功能,为未来研究 XCI 机制提供了新的思路。
