JAKs expressions in cell line PC_(12) induced by soman intoxication / 第三军医大学学报

ABSTRACT

Objective To investigate the effect of soman on the Janus kinases (JAKs) expression in cell line PC 12 . Methods The PC 12 cell was used in these experiments and treated with soman at a concentration of 20 ?mol/L . RT PCR and Western blotting were employed to detect the mRNA and protein expressions of JAK1, JAK2 and JAK3 at the time points of 0, 6, 12 and 24 h. The products were sequenced by Sanger's double strand DNA sequence determination. Results The expression levels of JAK1, JAK2 and JAK3 mRNAs and proteins increased at 2 h, reached the highest at 12 h and decreased at 24 h, but they were still higher than those of the control. It was shown that the sequences of amplification products by RT PCR were the same to corresponding ones in GenBank. Conclusion Soman intoxication enhances the expression of Janus kinases in PC 12 cells. JAKs genes may play an important role in brain injury due to soman intoxication.
