[Construction of hPARP1-deficient cell strain by RNA interference].
OBJECTIVE
To construct hPARP1-deficient cell strain which can be used in studying the functions and action mechanisms of hPARP1 gene.


METHODS
16-HBEs were transfected with two kinds of eukaryotic expression plasmids of hPARP1 gene short hairpin RNA to construct hPARP1-deficient cells (named as "16-HBEP1 and 16-HBEP2") and a negative control plasmids (named as 16-HBEN). The protein expression levels of hPARP1 gene in 16-HBE, 16-HBEP1 16-HBEP2 and 16-HBEN were detected by the western blotting to estimate the effects of RNA interference.


RESULTS
The construction of hPARP1-deficient cell strain was successful and the protein expression level of hPARP1 gene in the 16-HBEP1 and 16-HBEP2 were decreased 84.3% and 63.7% respectively as compared with that in 16-HBE.


CONCLUSIONS
The successes in constructing hPARP1-deficient strain offered an effective cell strain for studying the function of hPARP1 gene.
