ABSTRACT
<p><b>OBJECTIVE</b>To construct antisense c-Jun N-terminal kinase 1 (JNK1) eukaryotic fluorescent expressing vector and JNK1-/- human embryo lung fibroblasts cell line.</p><p><b>METHODS</b>Trizol reagent was used to extract total RNA in HELF. The proper primers of JNK1 were chosen and synthesized. RT-PCR and gene recombinant techniques were used to construct the fragment of JNK1. After purification, the PCR products were cut, and JNK1 were inserted reversely into eukaryotic fluorescent expressing vector pEGFP-C1. Enzyme-cutting and DNA auto-sequencing were used to prove the successful construction of JNK1 eukaryotic expressing vector. Then plasmids were extracted and transfected into HELF cells and screen by G418 24 h later. Monoclone was chosen and cultured. Fluorescent imaging and Western blot were used to identify the JNK1-/- HELF cell line.</p><p><b>RESULTS</b>Sequence analysis of pEGFP-C1-as JNK1 plasmids was same as expected. The expression level of JNK1 was inhibited markedly.</p><p><b>CONCLUSION</b>Construction of antisense JNK1 eukaryotic fluorescent expressing vectors and JNK1-/- HELF cell line is successful.</p>
