一、发表文章转染简述:

文章使用美国Zeta Life公司,#Advanced DNA RNA转染试剂(#AD600150,Zeta Life, USA) 将构建的pCMV-GSDMD-N-HA 载体质粒DNA(图 6A)转染到原代奶牛子宫内膜上皮细胞(BEECs), 48小时后用Western blotting检测GSDMD,并检测到蛋白表达确定转染成功(图 6B)。

重建细胞炎症模型,提取总蛋白,GSDMD表达及其裂解的N使用蛋白质印迹法检测末端蛋白。结果表明 BEEC 暴露于 LPS(10 和 30 µg/ml)24 小时可以裂解 GSDMD 并导致焦亡(图 6C)

1、LPS Exposure for 24 h Leads to BEEC Inflflammation and Cleaved GSDMD to Pyroptosis

We constructed a pCMV-GSDMD-N-HA vector (Figure 6A) and transfected it to BEECs to overexpress GSDMD, and detected protein expression withWestern blotting after 48 h to ensure the transfection was successful (Figure 6B). The cell inflflammation model was rebuilt,

total proteinwas extracted, and GSDMD expression and its cleaved N terminal protein were detected using Western blotting. The resultsshowed that BEEC exposed to LPS (10 and 30 µg/ml) for 24 h could cleave GSDMD and lead to pyroptosis (Figure 6C).

2、Genetic Recombination

Genetic Recombination Technology was adopted to ligate bovine GSDMD DNA fragments into the ampicillin-resistant pCMV-HA vector and transform it into E. coli. Brieflfly, the bacteria were grown on an LB agar medium containing ampicillin sodium for 24 h at 37°C. A single colony was picked and added to the LB liquid medium containing ampicillin sodium and culturedfor 16 h at 37°C with shaking at 300×g. Plasmid DNA was extracted with an Endo[1]free Plasmid Mini Kit I and quantifified using a Polluton100+. The Zeta Life Transfection Kit was used to transfect the plasmid into BEECs, and LPSwas used to construct the cell inflflammation model. The cell total protein was extracted and detected by an HA tag and Western blotting to evaluate the GSDMD protein expression and its cleavage during cell pyroptosis. The vector construction, restriction endonuclease cleavage verifification, and sequencing verifification were done by Genecreate Biological Company。
