A recombinant plasmid (pXJ41\|CKPα) containing a full length of protein kinase Cα cDNA in antisense orientation was transfected into human lung cancer LTEPa 2 cells by gene recombination and gene transfection.The LT·AS4 cells stably expressing antisense PKCα mRNA were constructed successfully.Expression of antisense PKCα mRNA in LT·AS4 cells was much higher than those of control cells transfected with the vector pXJ41\|neo only and parent cells.the PKCα level and PKC activity in LT·AS4 cells were much lo...
