ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of antisense oligonucleotides (ASODN) targeting protein kinase C alpha (PKCalpha) on the proliferation of A549 cells.</p><p><b>METHODS</b>PKCalpha ASODN and random oligonucleotides (RODN) were transfected into A549 cells mediated by polyethyleneimine, and the proliferation and clone formation of A549 cells were detected by CCK-8 and clone formation assay, respectively. The expression of PKCalpha in the transfected cells was analyzed by RT-PCR and Western blotting.</p><p><b>RESULTS</b>Compared with those in the control group, PEI group and PEI-RODN group, the proliferation and clone formation of A549 cells treated with ASODN targeting PKCalpha were significantly inhibited (P<0.05). The expressions of PKCalpha mRNA and protein in PKCalpha ASODN-transfected A549 cells were significantly lower than those in the other 3 groups (P<0.05).</p><p><b>CONCLUSION</b>The PKCalpha ASODN mediated by PEI down-regutates the expression of PKCalpha gene and suppress the proliferation and clone formation of A549 cells.</p>
