目的 建立转运蛋白颗粒复合物亚基11(Trappc11)诱导型基因敲除小鼠模型。方法和结果 在Trappc11基因外显子3~5的两侧分别引入loxP位点,利用CRISPR/Cas9技术获得F0代C57BL/6J小鼠;将通过PCR扩增及测序鉴定阳性的F0代C57BL/6J小鼠与C57BL/6J野生型小鼠交配、繁殖,获得F1代Trappc11flox/+小鼠;再将Trappc11flox/+小鼠与UBC-CreERT2小鼠交配,经过2代繁殖,最终获得Trappc11诱导型全身性基因敲除小鼠模型。结论 通过CRISPR/Cas9和Cre-loxP技术成功建立了Trappc11诱导型基因敲除小鼠模型,为揭示Trappc11在多器官系统疾病中的病理生理学作用提供了重要工具。 |

Abstract: |
Objective To establish an inducible knockout mouse model of trafficking protein particle complex subunit 11 (Trappc11). Methods and results LoxP sites were introduced on both sides of exon 3-5 of Trappc11, and then the CRISPR/Cas9 technique was used to establish F0 C57BL/6J mice. The positive F0 generation mice were identified by polymerase chain reaction amplification and sequencing. After that, F0 positive mice were mated with C57BL/6J wild type mice to obtain F1 Trappc11flox/+ mice. And then, Trappc11flox/+ mice were mated with UBC-CreERT2 mice, and finally Trappc11 inducible systemic knockout mouse model was obtained after 2 generations. Conclusion The Trappc11 inducible knockout mouse model is established using CRISPR/Cas9 and Cre-loxP, providing an important tool for revealing the pathophysiological role of Trappc11 in multi-organ system diseases. |
